GMNN and breast cancer: Similar association was also detected in breast cancer cell lines, where we found that cell lines expressing the highest levels of geminin e.g., MDA-MB-231 and MDA-MB-453 showed predominantly nuclear c-Abl expression (Fig. 5F), whereas cell lines expressing low levels of geminin e.g., MCF7 and SKBR3 showed predominantly cytoplasmic c-Abl expression (Fig. 5F).
