Figure 6. Sodium selenite induced HSP70 expression in a time-dependent manner. HLECs were treated with 4 ng/ml sodium selenite for 12, 24, and 36 h, respectively. The expression of HSP70 at the mRNA and protein levels was quantified by RT–PCR and western blot analysis, respectively. Each experiment was performed in triplicate.
