WebRather, distinct patterns of binding were observed. At common binding sites there was a tendency to greater enrichment of DNA in the anti-HIF2α chromatin immunoprecipitations, suggesting that affinity for HIF-2α was at least as high as for HIF-1α, whereas at other sites, binding was essentially restricted to HIF-1α. WebHypoxia response elements from these genes consist of a HIF-1 binding site (that contains the core sequence 5'-CGTG-3') as well as additional DNA sequences that are required … Web7 de jul. de 2024 · To assess the effects of HIF-1α binding at these sites, CRISPR/Cas9 guides were designed to delete one or both of the binding sites .

Here, an attempt was made for mining HRE and identifying functional HIF binding sites (HBS) in a genome-wide analysis of C. carpio. For this, gene information along with the 5,000-nt upstream (−4,900 to +100) sequences of 31,466 protein coding genes was downloaded from “Gene” and “RefSeq” databases. Ver mais Cyprinus carpio, commonly known as common carp, is a worldwide distributed freshwater carp fish of Family Cyprinidae, having vulnerable conservation status, and is a widely cultivated aquaculture species contributing about … Ver mais There are several reports on the in silico identification and prediction of HBS in the genome-wide analysis of mammals and fish (Benita et al., … Ver mais WebTo understand how HIF-1α regulates ASAP3 expression, we identified two potential HIF-1α–binding sites (HRE1-2) within the promoter and upstream of the transcription start site .
