FMNL2 and breast cancer: Compared to lower proliferative cells MCF7 and T47D, highly proliferative breast cancer cells MDA-MB-231, BT549 and SUM159 expressed high levels of FMNL2 along with high proliferative features including enhanced Ki67 and CyclinD1 levels, and reduced levels of p27 and p21 (Fig. 1c).
