Figure 1. Expression of TLR4 mRNA in SV40-HCEs cultured under 20% O2 (control group) or 2% O2 (hypoxia group). The expression of the mRNA of TLR4 decreased to about 10% of the control group under hypoxic conditions. The p-values were calculated using two-tailed paired t tests. The asterisk indicates a p<0.05.
