HNRNPA2B1 and breast carcinoma: We further clarified the subcellular localization of HNRNPA2B1 by immunofluorescence assay using glioma GL261 cells and breast cancer MDA-MB-231 cells, which showed that HNRNPA2B1 was expressed predominantly in the nucleus and to a lesser extent in the cytoplasm (Figures 2(s) and 2(t)).
