انواع سرطان ها، که در اثر عوامل مختلف از جمله ژنتیکی، اپی ژنتیکی، شیمیایی، اشعه یونیزان و غیره ایجاد می شوند، پس از اختلالات قلبی عروقی، جایگاه دوم علل مرگ و میر را درجهان تشکیل می دهند. سرطان دهان ششمین سرطان شایع در جهان بوده که باعث اختلال در عملکرد عضو درگیر، ناهنجاری غیر قابل ترمیم در شکل ظاهری بافت های دهان و صورت شده و نهایتا" منجر به مرگ می گردد. امروزه نقش عوامل اپی ژنتیکی، که بدون ت...
Within the tumor suppressor protein INK4 ~inhibitor of cyclin-dependent kinase 4! family, p15INK4B is the smallest and the only one whose structure has not been determined previously, probably due to the protein’s conformational flexibility and instability. In this work, multidimensional NMR studies were performed on this protein. The first tertiary structure was built by comparative modeling w...
N-WASP is a cytoplasmic molecule mediating Arp2/3 nucleated actin polymerization. Mice with a keratinocyte-specific deletion of the gene encoding N-WASP showed normal interfollicular epidermis, but delayed hair-follicle morphogenesis and abnormal hair-follicle cycling, associated with cyclic alopecia and prolonged catagen and telogen phases. The delayed anagen onset correlated with an increased...
Transplantation of vascular cells derived from human pluripotent stem cells (hPSCs) offers an attractive noninvasive method for repairing the ischemic tissues and for preventing the progression of vascular diseases. Here, we found that in a serum-free condition, the proliferation rate of hPSC-derived endothelial cells is quickly decreased, accompanied with an increased cellular senescence, resu...
Aberrant promoter hypermethylation profile of cell cycle regulatory genes in malignant astrocytomas.
Aberrant hypermethylation of the CpG islands in the promoter region plays a casual role in the inactivation of various key genes involved in the cell cycle regulatory cascade, which could result in loss of cell cycle control. The aim of the present study was to investigate the role of promoter methylation of genes with a proven involvement in the cell cycle regulation of malignant astrocytomas....
The 9p21.3 locus is the best replicated region to date for coronary artery disease (CAD). We investigated the association of 9p21.3 common variants with CAD, candidate gene expression including ANRIL, a non-coding RNA, followed by in vitro validation. Five variants, rs10757278, rs10757274, rs2383206, rs1333049 and rs4977574 were genotyped in 1,034 cases and 1,034 controls. Gene expression of C9...
