ET1 treatment of MDA-MB-231 cells induces DLX2 to DLX5 switch. Expression of DLX2 and DLX5 expression in of MDA-MB-231 cells treated with ET1. Subconfluent cultures were serum-starved and treated with vehicle alone (-) or ET1. RT-PCR analysis for DLX2, DLX5 and G3PDH was performed on total RNA isolated from individual wells.
