Fig. 3. Effects of STS on silica-induced collagen type I/III expression. Collagen type I/III expression (A & B) was determined by Western blotting. The experiments were repeated three times with reproducible results. ^P < 0.05 vs. control; *P < 0.05 vs. negative control group. #P < 0.05, ##P < 0.01 vs. silica treatment group.
