Triglycerides are a type of fat found in the blood. Having a low HDL cholesterol level. HDL is sometimes called the "good" cholesterol because it helps remove cholesterol from your arteries. Having high blood pressure. If your blood pressure stays high over time, it can damage your heart and lead to other health problems. Having a high fasting blood sugar. Mildly high blood sugar may be an early sign of diabetes. What causes metabolic syndrome? Metabolic syndrome has several causes that act together: Overweight and obesity An inactive lifestyle Insulin resistance, a condition in which the body can't use insulin properly. Insulin is a hormone that helps move blood sugar into your cells to give them energy. Insulin resistance can lead to high blood sugar levels. Age - your risk goes up as get older Genetics - ethnicity and family history People who have metabolic syndrome often also have excessive blood clotting and inflammation throughout the body. Who is at risk for metabolic syndrome? The most important risk factors for metabolic syndrome are: Abdominal obesity a large waistline An inactive lifestyle Insulin resistance There are certain groups of people who have an increased risk of metabolic syndrome: Some racial and ethnic groups. Mexican Americans have the highest rate of metabolic syndrome, followed by whites and blacks. People who have diabetes People who have a sibling or parent who has diabetes Women with polycystic ovary syndrome PCOS People who take medicines that cause weight gain or changes in blood pressure, blood cholesterol, and blood sugar levels What are the symptoms of metabolic syndrome? How is metabolic syndrome diagnosed? The most important treatment for metabolic syndrome is a heart-healthy lifestyle, which includes: A heart-healthy eating plan, which limits the amount of saturated and trans fats that you eat. It encourages you to choose a variety of nutritious foods, including fruits, vegetables, whole grains, and lean meats. Aiming for a healthy weight Managing stress Getting regular physical activity Quitting smoking or not starting if you don't already smoke If making lifestyle changes is not enough, you may need to take medicines. Can metabolic syndrome be prevented? The best way to prevent metabolic syndrome is through the heart-healthy lifestyle changes. NIH: National Heart, Lung, and Blood Institute. Start Here.

| Introductory Chapter: An Overview of Metabolic Syndrome and Its Prevention | IntechOpen | Proteins altered in MDD 19 Figure 1 and Supplementary Table 1 are predominantly related to oxidative phosphorylation Figure 2. In fact, the great majority of the proteins are subunits of cytochrome c, ATP synthase, or NADH dehydrogenase. An animal model of depression revealed that complexes from the electron transport chain were inhibited in the cerebellum and cortex when the animals were submitted to conditions of chronic mild stress Rezin et al. Therefore, the poor functioning of oxidative phosphorylation due to decreased electron transport chain activity Hroudová et al. Mitochondrial dysfunction has been linked to depression and may be explained by deficiencies in both concentration and activity of proteins required for the proper functioning of the electron transport chain Gardner and Boles, According to clinical studies, adults as well as children diagnosed with a primary OXPHOS disease present a higher incidence of major depression when compared to unaffected controls Koene et al. Also, significant decreases of mitochondrial ATP production rates and mitochondrial enzymes ratios were observed in MDD patients Gardner et al. Antidepressants, such as citalopram and venlafaxine promote changes in NADH dehydrogenase and cytochrome c oxidase, which indicates that those electron transport chain complexes are desirable drug targets and potential markers for MDD Hroudova and Fisar, Proteins found to be altered in BPD 48 Figure 1 and Supplementary Table 1 are mostly related to the TCA cycle and the electron transport chain Figure 2. Microarray analyses on postmortem brain tissue revealed that several mRNAs linked to the production of mitochondrial electron transport chain complexes I—V were expressed in lower levels in BPD Sun et al. Those findings agree with an important association between BPD and mitochondrial dysfunction Konradi et al. As the mitochondrial electron transport chain is responsible for OXPHOS, consequently, it accounts for most of the oxygen consumption by the cell and also is responsible for substantial ROS production Wang et al. Since polyunsaturated fatty acids, which constitute neuronal cell membranes, are very vulnerable to damage by ROS, BPD mitochondrial dysfunction may lead to overproduction of those reactive compounds, resulting in oxidative stress Wang et al. Catalase and other previously mentioned antioxidant enzymes, such as peroxiredoxins, glutathione S-transferase and superoxide-dismutase, were found to be altered in BPD, which confirms the theory that oxidative stress plays a role in BPD occurrence. Hence, valproate and lithium, which are the most commonly used mood stabilizers in the treatment of BPD, were shown to have neuroprotective effects when oxidative stress was induced in rat brains Cui et al. It has been reported that chronic treatment with those drugs results in an increased expression of cellular glutathione S-transferase Wang et al. Additionally, treatment with N-acetylcysteine, a precursor of antioxidant glutathione, led to a significant improvement in the course of BPD treatment Berk et al. Psychiatric disorders are highly prevalent worldwide and can have an early onset. This allows for substantial impairment for patients in both productive and social aspects of life, resulting in low level of education, work absenteeism, unemployment, social isolation, marital disruption, and the need for caregiving in many cases Kessler et al. One of the main underpins in psychiatry is the diagnosis, which relies entirely on a clinical evaluation when symptoms become evident. Although, when the disorder reaches this stage, it is usually already fully established, which indicates a higher severity in combination with less effective treatments Saia-Cereda et al. The underlying pathophysiology of these disorders remains undetermined and studies aiming to help in early detection and early intervention could yield substantial improvements to the outcome of the disorders Insel, For that reason, the use of quantitative proteomics to investigate disease-specific protein and pathway signatures can improve the understanding of psychiatric disorders Filiou et al. The presence of metabolic alterations related to energy pathways have been recurrently implied as one of the physiological features of SCZ, BPD, and MDD Shao et al. By collecting information acquired from patient postmortem brain proteomic research, with a focus on energy metabolism, we could establish molecular similarities among the disorders, in addition to highlighting which pathways were most affected in each one. This study highlights the importance of the connection between psychiatrists and researchers to facilitate access to patient samples and stimulate a more comprehensible knowledge base acquired in this field. Consequently, the constant update and increase of data deposited in postmortem brain banks will contribute to a better comprehension of the pathophysiological mechanisms of psychiatric disorders, which can in turn improve the diagnosis, treatment, and potential to overcome these conditions, resulting in improvements in quality of life for the patients.

The following factors increase your chances of having metabolic syndrome: Age. Your risk of metabolic syndrome increases with age. In the United States, Hispanics — especially Hispanic women — appear to be at the greatest risk of developing metabolic syndrome. The reasons for this are not entirely clear. Carrying too much weight, especially in your abdomen, increases your risk of metabolic syndrome. You're more likely to have metabolic syndrome if you had diabetes during pregnancy gestational diabetes or if you have a family history of type 2 diabetes. Other diseases. Your risk of metabolic syndrome is higher if you've ever had nonalcoholic fatty liver disease, polycystic ovary syndrome or sleep apnea. Having metabolic syndrome can increase your risk of developing: Type 2 diabetes. If you don't make lifestyle changes to control your excess weight, you may develop insulin resistance, which can cause your blood sugar levels to rise. Eventually, insulin resistance can lead to type 2 diabetes. Heart and blood vessel disease. High cholesterol and high blood pressure can contribute to the buildup of plaques in your arteries. These plaques can narrow and harden your arteries, which can lead to a heart attack or stroke. A healthy lifestyle includes: Getting at least 30 minutes of physical activity most days Eating plenty of vegetables, fruits, lean protein and whole grains Limiting saturated fat and salt in your diet Maintaining a healthy weight Not smoking.

Energy metabolism and metabolic syndrome -
In the group with diabetes, the risk of developing hypertension is twice and that of ischemic heart disease is approximately thrice as high. The risk of heart disease augments with an increase in the number of diverse risk factors, including obesity, diabetes, hypertension, hyperlipidemia, and heart disease, poses about 36 times higher risk when 3—4 risk factors are present simultaneously [ 1 ].
Furthermore, these diseases are known to enhance the risk of cancer, immunodeficiency, aging, and dementia, which are not directly linked to lifestyle-related diseases [ 2 , 3 ]. According to a — survey in the United States, According to a study by the Japanese Ministry of Health, Labor, and Welfare, one in two men and one in five women over the age of 40 years fall into MetS and its pre-groups.
In this introductory chapter of the book, I will outline 1 the mechanism of MetS and 2 recent research trends on the effective use of brown and beige adipocytes, which have gained attention as an approach for enhancing MetS reserves.
White adipose tissue WAT predominantly contains white adipocytes that are accountable for triglyceride storage. They also serve as endocrine organs by secreting diverse hormones, including adipokines. More than 10 hormones and miRNAs, including TNF-α, PAI-1, leptin, adiponectin, resistin, apelin, and chemelin, are adipokines secreted by white adipocytes [ 8 ].
These act as paracrine and perform crosstalk with nerves and several organs to help control blood glucose and lipid levels [ 8 , 9 ]. When normal body weight is maintained, the ratio of progenitor cells to white adipocytes is balanced and adipokines aid to control them with insulin.
However, if excessive intake of sugar and fat pursues, progenitor cells differentiate into white adipocytes, which then enlarge and attain their fat storage limit. Under such conditions, adipokines are irregularly secreted by white adipocytes, that are unable to transmit their signals appropriately [ 10 ].
WAT hypertrophy and abnormal adipokine secretion, resulting in mild chronic inflammation and insulin resistance, cause MetS development. Insulin resistance is defined as the inhibition of insulin-mediated signaling pathways, resulting in a hyperglycemic state. The mechanisms of insulin resistance associated with obesity are complex; however, the following are believed to be the major factors [ 8 , 11 , 12 ].
Due to tissue hypertrophy in obese subcutaneous fat, macrophage infiltration occurs through chemokines, including CCL2, triggering inflammation.
Macrophages differentiate into M1 macrophages, which activate innate immunity and generate inflammatory mediators. Inflammatory adipokine secretion from hypertrophic WAT also augments. TNF-α and IL-6, inflammatory adipokines, activate inhibitory molecules, including SOCS and JNK, which suppress IRS and inhibit insulin signaling causing insulin resistance.
Furthermore, PIP3 is degraded by phospholipid phosphatases, including PTEN, and stresses the endoplasmic reticulum, diminishing its function and inhibiting GLUT-4 migration to the plasma membrane.
Insulin resistance augments free fatty acids FFAs throughout the body, which strongly affect inflammation and insulin resistance [ 13 ]. The resulting ectopic deposition of FFAs in muscles and the liver results in serine phosphorylation in IRS-1, which inhibits insulin signaling.
FFAs also activate the NF-κB pathway and induce inflammation. Ectopic deposition of FFA also elevates diacylglycerol levels in the liver, resulting in reduced hepatic glycogen synthesis.
Conversely, white adipocytes secrete anti-inflammatory adipokines, including leptin, adiponectin, and apelin. Apelin promotes insulin sensitivity, glucose uptake, and lipolysis [ 14 ]. Recent studies have implied that obese individuals have elevated levels of leptin and apelin, thus causing resistance to these adipokines.
Persistent insulin resistance leads to abnormal glucose and lipid metabolism, resulting in high blood glucose and lipid concentrations. In the hyperglycemic state, ketone bodies are synthesized, causing type II diabetes mellitus T2DM.
Additionally, high LDL cholesterol causes adherence of oxidized lipids to blood vessels, which are phagocytosed by macrophages activated by chronic inflammation, creating plaques, thereby causing atherosclerosis.
Hypertrophic WAT increases the secretion of PAI-1, an adipokine that augments blood pressure and causes hypertension. Furthermore, hyperlipidemia, triggered by enhanced FFAs levels, is the source of a variety of other diseases.
Although FFAs bind to albumin and other blood proteins and are not toxic, excess FFAs impair the pancreatic mitochondria, causing dysfunction [ 15 ] and inability to secrete insulin, resulting in a more advanced form of T2DM. Chronic inflammation and disruption of the immune system cause chronic renal failure CDK , cancer, and aging [ 2 , 3 ].
Thus, MetS initiating with obesity leads to a state of insulin resistance and mild chronic inflammation, which in turn triggers consecutive development of diverse diseases.
Once T2DM, atherosclerosis, or chronic renal failure develop, their reversal becomes tremendously challenging. Therefore, to prevent MetS, it is imperative to eliminate insulin resistance and chronic inflammation during the pre-metabolic syndrome stage.
Here, we discuss brown and beige adipocytes, which have gained prominence as the best approach to improving metabolic syndrome.
Brown adipocytes are so named owing to their brown, muscle-like color; nevertheless, they accumulate and degrade fat rapidly. Beige adipocytes, which materialize in WAT upon cold stimulation, have an excellent ability like that of brown adipocytes but are not as brownish [ 16 ].
These adipocytes originate from different developmental lineages. Recently, it has been proposed that there may be numerous beige adipocytes depending on the WAT type [ 17 ]. Marker genes specific to brown and beige adipocytes have been found, including Cd and Cited1, specific for beige adipocytes, and Prdm16, Ucp1, and Pgc-1α are common markers for brown and beige adipocytes [ 18 , 19 ].
Brown and beige adipocytes are heat-producing cells that generate nonshivering heat through diverse mechanisms [ 16 , 20 , 21 ]. In the mitochondrial inner membrane, energy, including NADH, produced by the TCA circuit is employed to pump protons outside of the membrane, creating an energy difference inside and outside the membrane for ATP synthesis.
Brown and beige adipocytes have numerous mitochondria expressing uncoupling protein 1 UCP1 in their inner membrane.
On cold stimulation exposure, UCP1 opens ion channels and conjugates with anions, including long-chain fatty acids, to bring protons into the membrane. The energy lost in this process is converted to thermal energy, producing nonshivering heat. As mitochondria rush to restore the proton gradient via the TCA circuit, fatty acids are positively degraded by β-oxidation to produce acetyl CoA.
In this manner, brown and beige adipocytes generate heat in response to cold stimuli, causing rapid fatty acid degradation. Although not deliberated here, mechanisms other than UCP1 that activate heat production have recently been identified and several regulators have been determined [ 22 , 23 ].
This may be critical for reducing obesity, especially in the elderly and obese populations with few UCP1-positive adipocytes. It is well established that nonshivering heat produced by brown adipose tissue BAT is involved in thermoregulation of body temperature when animals awaken from hibernation and in humans in response to alterations in body temperature at birth.
Thermogenesis by UCP1 in brown adipocytes has been observed to be closely related to obesity and T2DM [ 24 ]. For example, in mice, UCP1 does not function well in individuals prone to obesity, and UCP1 functions well in individuals that are not prone to obesity. In humans, BAT, which is abundant in newborns, drastically decreases as they grow older or develop MetS, although it plays an imperative role in maintaining health in adults.
This decline is one of the reasons for the rapid rise in the incidence of MetS in adults over 40 years of age [ 25 ]. Therefore, augmenting the number of brown and beige adipocytes is expected to be an effective means of obesity and MetS [ 26 ]. Brown adipocytes not only play a role in fat metabolism through thermogenesis but have also been found to secrete cytokines, including FGF, follistatin, IL-6, CLCX14, or miRNA batokines , upon thermogenic activation.
Batokines work as paracrine and endocrine molecules and crosstalk with several organs [ 27 , 28 ]. For example, BMP8 promotes sympathetic innervation and angiogenesis in BAT, whereas NRG4 promotes sympathetic axon elongation and secretion.
FGF21 is released from BAT activated by thermogenesis and the liver, protecting against hyperlipidemia and nonalcoholic liver disease.
Thermogenesis-activated BAT also secretes IL-6, which helps maintain BAT metabolic homeostasis and enhances gluconeogenesis in the liver. Additionally, CLCX14 induces M2 macrophages and myostatin regulates skeletal muscle function.
Thus, batokines secreted from BAT and beige adipocytes are anticipated to suppress MetS. Activation of beige or brown adipocytes is primarily mediated by a pathway involving the β3-adrenergic receptor β3-AR [ 29 ].
Activated PKA phosphorylates pJMJD1A, CEBP, ATF2, and other proteins via p38 MAPK to enhance the expression of PPARγ, PGC1a, PRDM16, NFIA, and others [ 30 ]. Enhanced expression of PPARγ and PRDM16 induces browning and PGC1a augments the number of mitochondria, resulting in the induction of UCP1, CIDEAR, COX8b, CDK5, and others.
Experiments in mice in which PRDM16 was disrupted have demonstrated that it is vital for brown adipose tissue maintenance and WAT browning [ 31 ]. The transcription factor Zfp also plays a pivotal role in BAT development and cold-induced regulation.
Additionally, IFR4 ablation in mice drastically decreases thermogenesis and energy consumption [ 33 ]. This indicated that IRF4 interacts with PGC1α and is involved in energy expenditure. It is noteworthy that continuous cold stimulation is essential for the differentiation of pre-brown to brown adipocytes and white to beige adipocytes.
It has been reported that the modification from white to beige adipocytes is trans-differentiation, which returns to its original state once cold stimulation is stopped [ 34 ]. However, pathways have been found to activate BAT or induce beige adipocytes independent of BAT β3-AR signaling [ 35 ].
For example, adenosine A2A receptors bind to adenosine released by brown fat cells, and their activation can induce beige adipogenesis and suppress obesity [ 36 ].
It has also been demonstrated that UCP1 knockout mice adapt to cold environments by employing other compensatory pathways [ 38 ]. This β3-AR signaling-independent pathway will also be an imperative target for enhancing beige adipocytes in the future.
Beige adipocytes in humans have beneficial effects in alleviating insulin resistance and weight loss [ 39 ] and treating metabolic syndrome by converting into beige adipocytes which have been attempted.
The most representative approach for WAT browning is cold stimulation. Even in humans, cold exposure at 17°C every 2 h for 6 weeks augments BAT activity and reduces body fat percentage [ 40 ].
Thus, continuous cold stimulation is a simple and effective means to enhance BAT or beige adipocytes. BAT activation by agonists has also been explored.
Because the β3-AR of BAT acts on noradrenaline secreted by cold stimulation, β3-AR agonists also induce thermogenesis. For example, mirabegron, a β3-AR agonist, induces BAT activity and augments resting energy expenditure by up to 5.
PPARγ receptor agonists, such as rosiglitazone, also activate SIRT1-PRDM16 and induce beige adipocyte development in mice [ 43 ]. However, β3-AR and PPARγ receptors are distributed throughout the body, and their side effects are challenging and have not yet been acknowledged for the treatment of metabolic disorders.
Thus, researchers at Columbia University Medical Center are attempting to provide them specifically using a skin patch. The skin patch was equipped with several tiny needles. Additionally, cell therapy for direct BAT augmentation by transplantation is also being considered, as brown and beige fat cells can be produced from iPS cells and diverse other cells [ 45 , 46 ].
Moreover, there is also a requirement for foods that can reduce fat and promote the activation of BAT and WAT beige [ 47 ]. Active consumption of these foods will help obtain a lean body and prevent metabolic syndrome. Because cold stimuli are received by TRP channels on the vagus nerve, compounds that stimulate TRP channels, including capsaicin, gingerol, and allyl isothiocyanate, are expected to have a cold stimuli-like effect.
For example, when ingested, capsaicin or capsinoids activates the exchange nerve through its TRPV1 channel, and adrenaline is secreted [ 48 ]. When capsinoids were continuously ingested for 6 weeks, there was an increase in BAT and cold-induced heat production [ 40 ].
Additionally, EPA and DHA, or intestinal bacterial metabolites of unsaturated fatty acids, also have TRPV1 activating effects and have been reported to improve cold-induced heat production in BAT [ 49 ].
Food components with noradrenaline-like structures can stimulate β3-AR, and their continuous intake may induce brown or beige adipocytes.
We reported that Kikyo , the constituents of Bofutsushosan Chinese medicine , contain components that transdifferentiate mouse white adipocytes into beige adipocytes [ 50 ]. Another group reported that p-synephrine extracted from Citrus unshiu Marcow contains a component that converts to beige adipocytes [ 51 ].
It has also recently been demonstrated that sirtuins are closely involved in browning [ 52 ], SIRT3 is involved in mitochondrial function maintenance, and SIRT5 regulates UCP1. Furthermore, SIRT1 aids in the BAT gene transcription via PPARγ and activates PGC-1a [ 53 ]. Because SIRT1 is reduced by aging and age-related diseases, enhancing SIRT1 activity may prevent metabolic syndrome pathogenesis.
Additionally, it has been noted that chitosan, although not differentiating into beige adipocytes, acts on adipokines and has an inhibitory effect on obesity [ 55 ]. Experiments employing an animal model of diet-induced obesity indicated that chitosan oligosaccharide capsules activated the JAK2-STAT3 signaling pathway to mitigate leptin resistance, inhibit lipogenesis, and reduce lipid accumulation [ 56 ].
Obesity and MetS are becoming global diseases. The mechanisms by which MetS is caused have been elucidated. It is now comprehended that insulin resistance and mild chronic inflammation elimination are critical for MetS improvement and prevention and that augmenting brown and beige fat cells, which secrete batokines and improve insulin resistance, are vital for improving MetS.
Furthermore, recent progress in research on brown and beige adipocytes has been remarkable, and existence of UCP1-independent nonshivering heat and signaling pathways that exclude β3-ARs have been demonstrated. The significance of using brown and beige adipocytes in metabolic syndrome treatment is expected to intensify in the future.
We look forward to further research on brown and beige adipocytes. Licensee IntechOpen. This chapter is distributed under the terms of the Creative Commons Attribution 3.

While some proteins are constitutively phosphorylated, the majority present transitory phosphorylation, depending on the cellular conditions at a given time.
Proteome analyses of the corpus callosum, the largest white matter structure in the human brain, rich in glial cells revealed that several proteins were differentially phosphorylated Saia-Cereda et al.
Among them was the mammalian target of rapamycin mTOR , a kinase that is a component of the mTORC1 pathway, and it plays a role in regulating protein synthesis, mainly by direct and indirect phosphorylation Hay and Sonenberg, , as well as being an important regulator of intracellular communicatory mechanisms in glial cells Lisi et al.
The AMP-activated protein kinase AMPK is a cellular energy sensor and signal transducer that is regulated by a wide variety of metabolic stresses and AMPK directly phosphorylates multiple components in the mTORC1 pathway Inoki et al.
The relationship between mTOR and AMPK signaling pathways would make mTOR sensitive to even the lowest ATP depletion Tokunaga et al. Therefore, the observation of changes in phosphorylation profile in mTOR emphasizes impaired energy production in glial cells of SCZ patients.
Transketolase and 6-phosphogluconolactonase are related to oxidation-reduction process and were altered in SCZ. They are key enzymes in the pentose phosphate pathway PPP , which synthesizes the reduced form of nicotinamide adenine dinucleotide phosphate NADPH and ribosephosphate Horecker, ; Zhao et al.
This evidence, along with the lower levels of pyruvate reported, points to glycolysis being a key pathway in the pathophysiological processes of SCZ Martins-De-Souza et al.
Furthermore, aconitase, isocitrate dehydrogenase, malate dehydrogenase and oxoglutarate dehydrogenase have been found to be altered in SCZ and are related to the TCA cycle.
This points to alterations in mitochondrial pathways which are consistent with the concept that the broad mitochondrial processes are affected in the disorder Ben-Shachar, ; English et al. Whether it is mitochondrial function or glucose metabolism that is affected first in the establishment of SCZ has yet to be elucidated Martins-de-Souza et al.
Proteins altered in MDD 19 Figure 1 and Supplementary Table 1 are predominantly related to oxidative phosphorylation Figure 2. In fact, the great majority of the proteins are subunits of cytochrome c, ATP synthase, or NADH dehydrogenase.
An animal model of depression revealed that complexes from the electron transport chain were inhibited in the cerebellum and cortex when the animals were submitted to conditions of chronic mild stress Rezin et al. Therefore, the poor functioning of oxidative phosphorylation due to decreased electron transport chain activity Hroudová et al.
Mitochondrial dysfunction has been linked to depression and may be explained by deficiencies in both concentration and activity of proteins required for the proper functioning of the electron transport chain Gardner and Boles, According to clinical studies, adults as well as children diagnosed with a primary OXPHOS disease present a higher incidence of major depression when compared to unaffected controls Koene et al.
Also, significant decreases of mitochondrial ATP production rates and mitochondrial enzymes ratios were observed in MDD patients Gardner et al. Antidepressants, such as citalopram and venlafaxine promote changes in NADH dehydrogenase and cytochrome c oxidase, which indicates that those electron transport chain complexes are desirable drug targets and potential markers for MDD Hroudova and Fisar, Proteins found to be altered in BPD 48 Figure 1 and Supplementary Table 1 are mostly related to the TCA cycle and the electron transport chain Figure 2.
Microarray analyses on postmortem brain tissue revealed that several mRNAs linked to the production of mitochondrial electron transport chain complexes I—V were expressed in lower levels in BPD Sun et al.
Those findings agree with an important association between BPD and mitochondrial dysfunction Konradi et al. As the mitochondrial electron transport chain is responsible for OXPHOS, consequently, it accounts for most of the oxygen consumption by the cell and also is responsible for substantial ROS production Wang et al.
Since polyunsaturated fatty acids, which constitute neuronal cell membranes, are very vulnerable to damage by ROS, BPD mitochondrial dysfunction may lead to overproduction of those reactive compounds, resulting in oxidative stress Wang et al.
Catalase and other previously mentioned antioxidant enzymes, such as peroxiredoxins, glutathione S-transferase and superoxide-dismutase, were found to be altered in BPD, which confirms the theory that oxidative stress plays a role in BPD occurrence.
Hence, valproate and lithium, which are the most commonly used mood stabilizers in the treatment of BPD, were shown to have neuroprotective effects when oxidative stress was induced in rat brains Cui et al. It has been reported that chronic treatment with those drugs results in an increased expression of cellular glutathione S-transferase Wang et al.
Additionally, treatment with N-acetylcysteine, a precursor of antioxidant glutathione, led to a significant improvement in the course of BPD treatment Berk et al. Psychiatric disorders are highly prevalent worldwide and can have an early onset.
This allows for substantial impairment for patients in both productive and social aspects of life, resulting in low level of education, work absenteeism, unemployment, social isolation, marital disruption, and the need for caregiving in many cases Kessler et al.
One of the main underpins in psychiatry is the diagnosis, which relies entirely on a clinical evaluation when symptoms become evident. Although, when the disorder reaches this stage, it is usually already fully established, which indicates a higher severity in combination with less effective treatments Saia-Cereda et al.
The underlying pathophysiology of these disorders remains undetermined and studies aiming to help in early detection and early intervention could yield substantial improvements to the outcome of the disorders Insel, For that reason, the use of quantitative proteomics to investigate disease-specific protein and pathway signatures can improve the understanding of psychiatric disorders Filiou et al.
The presence of metabolic alterations related to energy pathways have been recurrently implied as one of the physiological features of SCZ, BPD, and MDD Shao et al. By collecting information acquired from patient postmortem brain proteomic research, with a focus on energy metabolism, we could establish molecular similarities among the disorders, in addition to highlighting which pathways were most affected in each one.
This study highlights the importance of the connection between psychiatrists and researchers to facilitate access to patient samples and stimulate a more comprehensible knowledge base acquired in this field. Consequently, the constant update and increase of data deposited in postmortem brain banks will contribute to a better comprehension of the pathophysiological mechanisms of psychiatric disorders, which can in turn improve the diagnosis, treatment, and potential to overcome these conditions, resulting in improvements in quality of life for the patients.

Diseases, including type 2 diabetes, heart disease, hypertension, stroke, chronic renal annd, and nonalcoholic hepatitis, are caused by incorrect Ketabolic, irregular lifestyle, megabolic environmental metabbolism. They are characterized by the onset of obesity and the concomitant development of one or more other diseases. In the group with diabetes, the risk of developing hypertension is twice and that of ischemic heart disease is approximately thrice as high. The risk of heart disease augments with an increase in the number of diverse risk factors, including obesity, diabetes, hypertension, hyperlipidemia, and heart disease, poses about 36 times higher risk when 3—4 risk factors are present simultaneously [ 1 ].
