Fig 3. Effects of the ROCK1 inhibition on pancreatic cancer cells and cancer-associated fibroblasts.

A) Fasudil dose response curves in pancreatic cancer cells treated for 72 hours. B) Tumor cell migration in ROCK1 siRNA treated cells. C) Fluorescence microscopic analysis of fasudil treated, co-cultured pancreatic cancer cells and cancer-associated fibroblasts. Cells were treated with fasudil for 48 hours and then were stained for α-SMA (red), Collagen I (green), and DNA (blue). D) Fluorescence microscopic analysis of fasudil treated CAFs. E) Fasudil treated, mono- and co-cultured pancreatic cancer cells and cancer-associated fibroblasts were harvested and analyzed by immunoblotting (dot blot) for Collagen I expression under non-denaturing conditions.
