Figure 1. Temporal expression of HIF-1α under short-term and prolonged hypoxia.

Figure 1

HepG2 cells were exposed to 1% O2 for 0-24 h and the mRNA (A, B) and protein (C, D) expressions of HIF-1α, HIF-1β, NF-κB-p50, p65 and c-Rel were assessed. The results were expressed as the means (A) or means±SEM (B and D) of n = 4 independent experiments and normalized with β-actin (ACTB).
