mRNA expression profile of selected oxygen sensing genes in the lung during recovery from chronic hypoxia
This study analyzed the time dependence decay of the mRNA of selected genes important for the hypoxia response. The genes chosen were the two isoforms of hypoxia-inducible factors, the three isoforms of the prolyl hydroxylase domain protein, the vascular endothelial growth factor and endothelial nit...
