The inhibitory effects of targeted regulatory genes on the proliferation and invasion of osteosarcoma cells were studied through various in vitro experiments include bioinformatics combined with tissue microarray research, transcription factor prediction combined with co-expression analysis to predict the transcription factor of targeted regulatory genes in osteosarcoma. The RXR protein family, LKB1, AMPK pathway, and mTOR are closely related to the body’s immune regulation. The oral administration of Bexarotene could inhibit the proliferation and able to up-regulate the expression of LKB1 gene in living osteosarcoma tissue. The xenograft model of immunodeficiency nude mice used in this study was reason for reduced the potential immunoregulatory effect of drug targeted LKB1 therapy to a certain extent. However, overexpression of LKB1 in vivo, and combined immunotherapy may become an important immunotherapy approach for osteosarcoma. LKB1 targeted therapy can potentially be used as one of the alternative treatments for mTOR inhibitors.","PeriodicalId":54956,"journal":{"name":"International Journal of Human Genetics","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2021-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48268877","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}

One of the closely related species to Homo sapiens is Neanderthals, which became extinct about 30,000 years ago. The aim of this research is to compare Homo sapiens with Neanderthals and chimpanzees to understand the patterns of inheritance and survival instincts of Homo sapiens. Results show that out of all selected groups of genes in this study, metabolism, and language genes are found to be the most evolving group of genes. This shows that these most evolving genes are contributing to the advancement of Homo sapiens. However, after comparing human intelligence genes with the primates, it is found that exonic regions are contributing more to the evolution of human intelligence hence, making Homo sapiens unique in terms of intelligence.","PeriodicalId":54956,"journal":{"name":"International Journal of Human Genetics","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43695248","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}

While eight of those SNPs, five from FTO and one each from MTCH2, DENNDIA and THADA genes, were found to be associated in the first set involving obese PCOS cases, only three SNPs (IRS2-intronic, LOC107984901-intergenic and SUMO1P1-regulatory variants) showed association in the 2nd set involving non-obese cases. The SNPs associated in the two cohorts were distinct and mutually exclusive. However, all the SNPs associated in either obese or non-obese PCOS cohorts were not only risk-prone but also broadly represented a metabolic pathway, involving mostly obesity and T2DM related genes, prompting one to surmise if the recent spurt in PCOS prevalence is not driven by changes in the lifestyles.","PeriodicalId":54956,"journal":{"name":"International Journal of Human Genetics","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41856093","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}
