Effect of hypoxia on serine threonine kinase TGF-β receptor mRNA levels.
RNase protection analysis of mRNA extracted from HUVECs after exposure to 20% O2 or 1% O2 at indicated times. Control represents mRNA from normoxic HUVECs. Each lane contained 10 μg total RNA hybridized to the antisense RNA probe cocktail. Results are from a single gel in which lanes are separated for display purposes.
