After binding, … Web1 de fev. de 2024 · HIF-2 binding sites were observed to associate with tissue-specific transcription factors, suggesting that interactions with other transcription factors might …
WebWe also show that hypoxic regulation of Ang-2 is HIF-dependent and demonstrate that HIF-1alpha binds in human microvascular endothelial cells (HMVEC) to an evolutionary … 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 …
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 … Web9 de jun. de 2011 · Although HIF-α proteins were originally defined as part of a dimer with HIF-1β that bound DNA at hypoxia response elements, interactions with other …
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 …
