objective: the incidence of breast cancer is approximately one million which makes this cancer one of the most common among women worldwide. breast cancer comprises 7% of the total death rate caused by cancers. several strategies that use tumor-associated antigen (taa) vaccination and early detection of breast cancer are clinically being developed. breast cancer is caused by increased over expr...
background: niche cells, regulating spermatogonial stem cells (sscs) fate are believed to have a reciprocal communication with sscs. the present study was conducted to evaluate the effect of ssc elimination on the gene expression of glial cell line-derived neurotrophic factor (gdnf), fibroblast growth factor 2 (fgf2) and kit ligand (kitlg), which are the main growth factors regulating sscs deve...
background: peroxisome proliferator activated receptor gamma (pparγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. these two isoforms are encoded by different mrnas, which are arisen by alternative promoter usage. there are two promoter regions upstream of pparγ gene. a 3 kb fragment, containing several transcription factor binding sites, acts as pparγ1 promoter re...
calorie restriction through ingesting no or minimal amounts of food and caloric beverages for periods of time is called fasting. fasting can affect body through changing in physical and metabolic adaptations, as well as mineral and hormonal status. however, psychological effects and sometimes medical complications are likely in case of inappropriate fasting. fasting is associated with changes i...
background: vast variety of intermediate factors including cell cycle regulators, growth factors, transcription factors, and signaling pathways are involved in hematopoietic stem cell (hsc) commitment and differentiation into distinct lineages. vhl, ecad, and runx3 are among these. epigenetics is currently introduced as a potential mechanism to control the gene regulation. the aim of this study...
Recently, the National Labor Relations Board (the “NLRB” or “Board”) issued three highly anticipated opinions following the Supreme Court’s decision in NLRB v. Kentucky River Community Care, Inc. , 1 involving the definition of the term “supervisor” under the National Labor Relations Act (the “NLRA” or “Act”). The Board’s decisions, which have been referred to as “the Kentucky River decisions,”...
lentinan a polysaccharide from medicinal mushroom i.e lentinus, has been known to have anticancer properties. telomerase activity is not observed in normal healthy cells, whereas in cancerous cells telomerase expression is high. telomerase represents a promising cancer therapeutic target. we investigated the inhibitory effect of lentinan on telomerase reverse transcriptase gene (htert) which is...
Dendritic cells (DCs) are key mediators of immune function through robust and tightly regulated presentation of antigen in the context of the MHC Class II. MHC Class II expression is controlled by the transactivator CIITA. CIITA expression in conventional DCs is uniquely dependent on an uncharacterized myeloid cell-specific promoter, CIITApI. We now identify in vivo the promoter structure and f...
