HNRNPC and breast cancer: Notably, hsa-miR-944 was down-regulated in BC tissues compared with normal tissues from 3 GEO datasets (Additional file 1: Table S4) and HNRNPC was up-regulated in BC tissues from other 4 GEO datasets (Additional file 1: Table S5), validating the potential negative correlation between hsa-miR-944 and HNRNPC.
