Down Regulation of Osteocalcin Gene in Chickens Treated with Cadmium
Background: Cadmium is one of the heavy metals with harmful effects on different body organs and systems. The aim of this study was to investigate the harmful effects of cadmium, as a heavy metal, on the histological structure of bone and the expression of osteocalcin gene. Methods: Forty chickens were obtained, anesthetized and their femurs were surgically removed. The real time polymerase ch...
متن کاملRoles of Chromatin insulators in gene regulation and diseases
With advances in genetic science, the dynamic structure of eukaryotic genome is considered as basis of gene expression regulation. Long-distance communication between regulatory elements and target promoters is critical and the mechanisms responsible for this connection are just starting to emerge. Chromatin insulators are key determinants of proper gene regulation and precise organization of c...
متن کاملEffect of dexamethasone on hexamethylene bisacetamide-induced Friend cell erythrodifferentiation.
Friend erythroleukemic cells can be induced to differentiate by chemicals such as dimethyl sulfoxide and hexamethylene bisacetamide (HMBA) in a dose-dependent manner. Others have shown that dexamethasone and other steroid hormones can inhibit the differentiation induced by dimethyl sulfoxide. We show here that dexamethasone has a dual mode of action on the HMBA-induced differentiation of a Frie...
متن کاملregulation studies of telomerase gene in cancer cells by lentinan
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...
