a WB of PIK3R3 and p21 both in LoVo and SW48 cells transfected with siNC, siPIK3R3#1, and siPIK3R3#2. b CCK8 assays of LoVo and SW48 cells transfected with PIK3R3-specific siRNA. c BrdU-positive cells percent of PIK3R3-knockdown LoVo and SW48 cells. d Cell cycle distribution of LoVo and SW48 cells transfected with siNC, siPIK3R3#1, and siPIK3R3#2 was measured by flow cytometry. e, f SA-β-gal staining of PIK3R3-knockdown LoVo or SW48 cells after treatment of Dox (0.25 μM, 48 h). Every assay repeated three times, and these numeral results were displayed as mean ± SD, *p < 0.05, **p < 0.01, ***p < 0.001, t-test.
