Effect of hypoxia on gene expression by human hepatocytes (HepG2)

Abstract excerpt

The full extent to which hypoxia produces gene expression changes in human cells is unknown. We used late-generation oligonucleotide arrays to catalog hypoxia-induced changes in gene expression in HepG2 cells. Five paired sets of cultures were subjected to either control (room air-5% CO(2)) or hypoxic (1% O(2)-5% CO(2)) conditions for 24 h, and RNA was analyzed on an Affymetrix cDNA array containing approximately...
