Induced expression of PPM1A inhibits ER-negative but not ER-positive growth in vitro. a PPM1A and Vinculin protein expression in multiple breast cancer lines cell. b Doxycycline-induced protein expression of PPM1A and vinculin in MCF7, MDA-MB-231 and SUM159 breast cancer cells. c–e Analysis of breast cancer cell line proliferation upon PPM1A expression. f–h Analysis of breast cancer cell line anchorage-independent colony formation upon PPM1A expression. All error bars represent SD, and n = 3. p-values were calculated using Student’s t-test
