Hif binding site
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 . To determine whether HIF-1α binds these HREs, we performed a CHIP assay using anti-HIF-1α antibodies in A549 cells cultured under hypoxic (1.5% O 2 ) or normoxic (21% O … Web11 de nov. de 2015 · To identify the dependency of these transcriptional changes on HIF, we undertook Chromatin Immunoprecipitation linked next generation sequencing (ChIP-seq) …

Web14 de out. de 2009 · Background Hypoxia-inducible factor 1 (HIF-1) plays a key role in cellular adaptation to hypoxia. To better understand the determinants of HIF-1 binding and transactivation, we used ChIP-chip and gene expression profiling to define the relationship between the epigenetic landscape, sites of HIF-1 binding, and genes transactivated by … Web1 de mai. de 2002 · The structure shows that a 15–amino acid portion of HIF-1α (residues 561 to 575) adopts an extended, β strand–like conformation ( Fig. 1 A). It binds pVHL in a bipartite manner, with two discontinuous HIF-1α segments interacting with a continuous site on pVHL. A six-residue NH 2 -terminal segment (residues 561 to 566; N segment) that is ...
WebPretreatment with IL-10 altered the binding pattern, with 120 new HIF-1 and 188 new HIF-2 binding sites emerging. HIF-1 binding was most prominent in promoters, while HIF-2 … WebHIF-1α and HIF-1β can dimerize, and bind to the enhancer region to increase its promoter activity. HIF-1 commonly has the binding site “RCGTG” in the enhancer region.41,42,44
WebWe identified another potential HIF-1 binding site U, 5′-TGCGTGCG-3′, immediately upstream of site D, which differed from known HIF-1 binding sites by the presence of a G, rather than A, residue at the second position. Expression of p2.7, containing a 3-bp substitution in site U, was only induced 2-, 11-, ... 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
