Fig. 8. Exogenous BMP-7 reduced silica-induced an increase of transcription factors. The levels of Snail (A, B and G), Slug (A and H), Twist (A, D and I), ZEB-1 (A, C and E) and ZEB-2 (A and F) were significantly decreased in lenti-BMP-7 cells compared with levels in lenti-GFP cells. *P < 0.05 vs. control, #P < 0.05 vs. silica + lenti-GFP.
