This has become a more frequent phenomenon in most neurological and neurodegenerative diseases as well as in dementia. In recent years such event of protein aggregation has linked to other disease conditions, disorders or adverse health conditions. Interestingly, aggregation of protein also plays role in development, growth or metabolism. Most often physiological proteins are initially bio-synthesised in native or nascent geometrical forms or conformations but later they undergo specific folding pattern and thereby acquire a stable configuration that is biologically relevant and active. It is highly important that these proteins remain in their biologically active configuration in order to exert their functional properties. Any alteration or change to this structural configuration can be detrimental to their specific functions and may cause pathological consequences leading to the onset of diseases or disorders. Several factors such as the action of chaperones, binding partners, physiological metal ions, pH level, temperature, ionic strength, interfacial exposure (solid-liquid, liquid-liquid, gas-liquid), mutation and post translational modification, chemical changes, interaction with small molecules such as lipids, hormones, etc. and solvent environment have been either identified or proposed as important factors in conferring the ultimate status of protein structure and configuration. \u0000Among many misfolding protein conformations, self-assembly or aggregation is the most significant. It leads to the formation of highly oligomeric self-aggregates that precipitate and interfere with many biochemical processes with serious pathological consequences. The most common implication of protein aggregation leading to the formation of deposits / plaques of various morphological types is the onset of neurological and neurodegenerative diseases that include Alzheimer’s, Parkinson’s, Huntington, ALS (Amyotrophic Lateral Sclerosis), CJD (Creutzfeldt Jakob Dementia), Prion diseases, Amyloidosis and other forms of dementia. However increasingly studies revealed that protein aggregation may also be associated with other diseases such as cancer, type 2 diabetes, renal, corneal and cardiovascular diseases. Protein aggregation diseases are now considered as part of “Proteinopathy” which refers to conditions where proteins become structurally abnormal or fail to fold into stable normal configurations. In this review, we reflect on various aspects of protein self-aggregation, potential underlying causes, mechanism, role of secondary structures, pathological consequences and possible intervention strategies as reported in published literatures. \u0000\u0000","PeriodicalId":50601,"journal":{"name":"Current Proteomics","volume":"26 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74040726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An increase in catalase activity (4.8876 ±\u00001.7123) whereas decrease in antioxidant GSH levels (0.213 ± 0.015µmol/ml) have been observed in SZ brain. Elevated\u0000TBARS level (0.3801 ± 0.0532ug/ml) were obtained in brain regions SZ patients compared with their controls that reflects\u0000an increased lipid peroxidation (LPO).\u0000\u0000\u0000\u0000Conclusion: We propose the role of HNE modified proteins possibly associated with the pathology of\u0000schizophrenia. Our data revealed increase lipid peroxidation as a consequence of increased TBARS production.\u0000Furthermore, altered cellular antioxidants pathways related to GSH and CAT also highlight the involvement of oxidative\u0000stress in schizophrenia pathology.","PeriodicalId":50601,"journal":{"name":"Current Proteomics","volume":"141 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80061153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developments in proteomic tools have\u0000also resulted in their application for addressing the safety and authenticity issues including meat species identification,\u0000detection of animal by-products, non-meat ingredients and tissues in meat products, traceability, identification of genetically\u0000modified ingredients, chemical residues and other harmful substances. Proteomic tools are also being used in some of the\u0000potential areas like understanding the effect of animal transportation, stunning, slaughter stress, halal authentication and\u0000issues related to animal welfare. Emerging advances in proteomic and peptidomic technologies and their application in\u0000traceability, meat microbiology, safety and authentication is taking a major stride as an interesting and complementary\u0000alternative to DNA based methods currently in use. Future research in meat science need to be linked to emerging\u0000metabolomic, lipidomic and other omic technologies for ensuring integrated meat quality and safety management. In this\u0000paper, a comprehensive overview of the use of proteomics for the assessment of quality and safety in meat value chain and\u0000their potential application is discussed.\u0000","PeriodicalId":50601,"journal":{"name":"Current Proteomics","volume":"96 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75238463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
