It has been extensively researched over the past decades, but the underlying mechanisms of its growth, proliferation, invasion, and metastasis require further investigation. Dysregulation of O-GlcNAcylation which is one of the most abundant post-translational modifications, impacts on the malignant features of breast cancer. O-GlcNAcylation is broadly recognized as a nutrient sensor and participates in cells' survival and death. Through its involvement in protein synthesis and energy metabolism, especially glucose metabolism, O-GlcNAcylation enables adaptation to a hostile environment. It supports the migration and invasion of cancer cells and may be crucial for breast cancer metastasis.

NOX hyperactivation has been associated w several diseases. This enzyme is a membrane-bound complex made up of six subunits when it is active. These enzymatic subunits are considered to be potent inhibitors of enzyme activity and good targets for reducing oxidative stress. Methods: The present study aimed to analyze the possible targets: the different subunits of NOX, for their interactions with apocynin to identify its possible mechanism of inhibition for NOX, using in silico tools. Monomer, dimer, and trimer of apocynin were docked to various subunits of NOX. Results: Comparable glide scores were obtained when the monomer and dimer of apocynin were docked with p47phox complete subunit of NOX and were better than in comparison to trimer. Free Energy of Binding (FEB) was highest in the case of the trimer (-37.4 Kcal/mol), followed by the dimer (-21.2 Kcal/mol) and monomer (-18.2 Kcal/mol). Dimer obtained the highest glide score of 8.25 (FEB =-25.1 Kcal/mol) with p67phox-isoform 2. The PH domain of p47phox and the SH3 domain of p67phox have their own best binding energy with dimmer. While molecular docking with Rac-Zn-GD, P, dimer, and trimer have shown comparable FEB. The residues, on which the ligands were found to interact, were of major significance being present in those domains that vicinity to inhibit or activate the complex and are important for the protein structure and functioning. MDS studies have confirmed the findings that the Apocynin trimer molecule has superior stability and interactions with the enzyme complex. Conclusion: It can be concluded from the study that trimer and dimer have better interactions in terms of FEB with p67phox and p47phox, indicating the reported findings in the literature.","PeriodicalId":9845,"journal":{"name":"Cellular Physiology and Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46003103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been linked to inflammation, oxidative stress, insulin resistance, hormonal changes (i.e. alterations in the levels or activity of hormones which can occur due to a variety of factors, including aging, stress, disease, medication, and environmental factors), and impaired muscle satellite cell activation. The gut microbiome is also essential for muscle health, and supplements such as probiotics, prebiotics, protein, creatine, and betaalanine can support muscle growth and function while also promoting gut health. Chronic low-grade inflammation is a leading cause of sarcopenia, which can activate signaling pathways that lead to muscle wasting and reduce muscle protein synthesis. Insulin resistance, hormonal changes, and impaired muscle satellite cell activation contribute to sarcopenia, and high levels of fat mass also play a role in the pathogenesis of sarcopenia. Resistance exercise and dietary supplementation have been shown to be effective treatments for sarcopenia. In addition, a combination of resistance exercise and supplementation has been shown to have a more significant beneficial effect on anthropometric and muscle function parameters, leading to a decrease in sarcopenic state. Thus, understanding the relationship between the gut microbiome and muscle metabolism is crucial for developing new treatments for sarcopenia across age groups.</p>","PeriodicalId":9845,"journal":{"name":"Cellular Physiology and Biochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9830250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
