Fig. 1. Effects of SiO2 on σ-1R expression and collagen production in HPF-a.

Fig. 1

a Representative western blot showing SiO2-induced σ-1R upregulation in a time-dependent manner. b Densitometric analysis of σ-1R from five experiments; * p < 0.05 vs the control group. c SiO2 upregulated collagen I and collagen III expression levels in a time-dependent manner. d Densitometric analysis of collagen I and collagen III from five experiments; * p < 0.05 vs the control group. e Representative immunocytochemical images showing that SiO2 increased σ-1R and collagen III expression levels in HPF-a, which was attenuated by pretreatment of BD1047 (10 μM)
