Chemotherapy induced nuclear translocation of CREB3L1 in MDAMB231 cells. Immunofluorescence analysis of GRP78 and CREB3L1 expression 24 h after cell treatment with doxorubicin and paclitaxel: (A) MCF7 cells, (B) BT474 cells, (C) MDAMB468 cells, (D) MDAMB231 cells. Note GRP78 staining (red), CREB3L1 staining (green), and merged staining (yellow) by cell type (63 × magnification, scale bar = 10 μm). (E) Fluorescence intensity (FI) of CREB3L1 and GRP78 expression. (F) Dot Blot FACS analysis of the cytoplasmic and nuclear expression of CREB3L1 in the different breast cancer cell lines.
