Polymorphisms of DGAT1 and STAT5A genes in Xinong Saanen and Guanzhong goat breeds were investigated. PCR-RFLP, SSCP, and DNA sequencing were used to identify three SNPs: DQ380250:g.407_408insC in the DGAT1 gene, AJ237937:g.6798C>T and g.6852C>T in the STAT5A gene. In DGAT1 g.407_408insC locus, the frequencies of C– allele were 0.79–0.85, and frequencies of C+ allele were 0.21–0.15. At STAT5A g...
Here we report that RNA interference against ATM inhibited p53 accumulation in cells expressing oncogenic STAT5 and cooperated with Rb inactivation to suppress STAT5A-induced senescence. Knocking down ATM was also effective to bypass E2F1-induced senescence and in combination with Rb inactivation, inhibited RasV12-induced senescence. Cells that senesced in response to ca-STAT5A or RasV12 accumu...
STAT transcription factors are tyrosine phosphorylated upon cytokine stimulation and enter the nucleus to activate target genes. We show that Rac1 and a GTPase-activating protein, MgcRacGAP, bind directly to p-STAT5A and are required to promote its nuclear translocation. Using permeabilized cells, we find that nuclear translocation of purified p-STAT5A is dependent on the addition of GTP-bound ...
فعال شدن گیرنده هورمون رشد (ghr) از طریق اتصال آن با هورمون رشد (gh) میانجی گری می شود و مجموعه (gh-ghr) سبب تغییر در متابولیسم چربی ها، پروتئین ها، مواد معدنی و کربوهیدرا ت ها و همچنین تمایز سلول ها می شود. فاکتور موثر بر بیان هورمون های هیپوفیزی (pit-1) ، از فاکتورهای ناظم مثبت در سنتز هورمون رشد و پرولاکتین در هیپوفیز پستانداران است. فاکتور القاء کننده اطلاعات بیولوژیک و فعال کننده فعالیت رو...
specific trait candidate genes are sequenced genes with known biological activity. the effects of pou1f1 and stat5a on milk production traits have been studied in several studies. pou1f1 affects on transcription of prolactin and growth hormone gene, as well as, stat5a is known as a main mediator of growth hormone action on target genes and intracellular mediator of prolactin signaling. since th...
Organic anion transporting polypeptides (Oatp) mediate the transport of a wide variety of amphipathic organic substrates. Rat Oatp1b2 and human OATP1B3 are members of a liver-specific subfamily of Oatps/OATPs. We investigated whether prolactin (PRL) and growth hormone (GH) regulated Oatp1b2 and OATP1B3 gene expression via signal transducers and activators of transcription 5 (Stat5). Binding sit...
The most widely used plasticizer, di-(2-ethylhexyl) phthalate (DEHP), is known to affect lipid metabolism and adipogenesis. We studied the effects of dietary DEHP exposure on metabolism in rats as well as the role of the JAK/STAT pathway in this process. Eighty rats were exposed to DEHP (0, 5, 50 and 500 mg/kg/d) through dietary intake for 4 weeks. We then collected blood samples, liver, and ad...
Tudor staphylococcal nuclease (Tudor-SN) is a highly conserved and ubiquitously expressed multifunctional protein, related to multiple and diverse cell type- and species-specific cellular processes. Studies have shown that Tudor-SN is mainly expressed in secretory cells, however knowledge of its role is limited. In our previous work, we found that the protein level of Tudor-SN was upregulated i...
