GABARAPL1 and breast cancer: In order to characterize the pathway allowing epigenetic modifications to control GABARAP family expression, we first analyzed GABARAP, GABARAPL1 and GABARAPL2 mRNA levels using qRT-PCR in MCF-7 and MDA-MB-453 (BC cell lines) and MCF-10A (Breast immortalized but non tumoral cell line) cell lines (Fig. 3a).
