Knockdown of ROCK1 by siRNA in pancreatic cancer cell inhibits cell proliferation.
A) ROCK1 was detected in pancreatic cancer cell lines (PANC-1, Mia PaCa-2, SU.86.86, BxPC3, AsPC-1, and HS766T), the immortalized normal pancreatic ductal epithelial cell line (HPDE6), and the cancer associated fibroblasts (CW-1) by Western blotting. B) Western blotting analysis of ROCK1 knockdown by siRNA over the course of 72 hours. (C) Western blotting analysis of ROCK1 knockdown by siRNA (72 hour treatment) in two cell lines, SU.86.86 and PANC-1. (D) Growth curves of pancreatic cancer cells (PANC-1 and SU.86.86) treated with siRNA to ROCK1. * P < 0.001 (compared to the untreated control). UT, untreated; tR, transfection reagent only; NT, non-targeting; ASD, cell death (positive) control; R1, ROCK1 siRNA1; R2, ROCK1 siRNA 2.
