Expression of glutathione S-transferase π and α isoforms in breast cancer cell lines. Expression of glutathione S-transferase (GST)-π and GST-α isoforms in breast cancer cell lines. Protein lysates were obtained from exponentially growing MDA-MB-231, F10, and MCF-7/COX-2 cells. Western blot analyses using polyclonal GST-π and GST-α antibodies were performed. β-actin was used as a loading control.
