Web1 de fev. de 2015 · Hypoxia and inflammation are intimately linked. It is known that nuclear factor κB (NF-κB) regulates the hypoxia-inducible factor (HIF) system, but little is known about how HIF regulates NF-κB. Here, we show that HIF-1α represses NF-κB-dependent gene expression. HIF-1α depletion results in increased NF-κB transcriptional activity both … Web21 de nov. de 2007 · Hif1a +/+ and Hif1a –/– kidneys were stained for collagen content (sirius red staining of collagen fibers shown in red; original magnification, ×200; n = 8 for mutant and n = 7 for control), macrophage marker F4/80 (original magnification, ×400; n = 3 in each group), and EMT marker FSP-1 (original magnification, ×400; n = 9 for mutant ...
