(A) Depletion of PP1cγ1 did not affect fibrinogen adhesion. n=4. (B) Compared to control siRNA, the decreased adhesion of PP1cβ depleted cells were significant at ◆p=0.005, *p=0.001. n=5-6. (C). Compared to control siRNA, the increased adhesion of PP1cα depleted cells were significant at ◆p=0.01, *p<0.0001. n=8-12. (D) Compared to control HA, the decreased adhesion of PP1cα HA overexpressing cells were significant at ◆p<0.001, *p=0.006. n=5-9.
