Analysis of hypoxia-inducible factor-1alpha (HIF-1alpha) null mutant hepatocytes subjected to hypoxic conditions for 8 hours. The HIF-1alpha transcription factor is a key regulator of oxygen homeostasis. Results provide insight into hepatocyte gene expression changes induced by short-term hypoxia.

(Submitter supplied) The primary aim of this study was to evaluate the changes in hepatocyte gene expression under short-term hypoxic conditions in wild type and HIF-1a null cultures. To this end, hypoxia treated cultures were subjected to incubation with 1% O2/5% CO2/94% N2 at 37° C for eight hours prior to RNA isolation. Duplicate normoxic controls were established from separate animals wherein cultures were untreated and treated with Adbgal. more...

(Submitter supplied) Keloids are reactive or spontaneous fibroproliferative dermal tumors characterized by the exaggerated and uncontrolled accumulation of extracellular collagen. Current approaches to mitigate keloidogenesis are largely procedural in nature. However, a better understanding of its biological drivers may lead to novel targeted treatments for keloids. Through whole-genome expression analysis, we found that a HIF-1α transcriptional footprint is preferentially upregulated (activation score=2.024; p=1.05E-19) in keloid fibroblasts (KFs) compared to normal dermal fibroblasts (NFs). more...

(Submitter supplied) The liver is one of most important organs in our bodies. It performs many essential functions including metabolism, synthesis, secretion, detoxification, and storage. Hepatocytes are the principal cell type in the liver and are involved in multiple liver-specific functions. There have been several efforts to develop in vitro culture systems capable of maintaining hepatocyte-specific phenotype over long time periods. more...
