Cytotoxicity in MDA-MB-231 cells after MHI-palbociclib treatment is significantly greater than after treatment with palbociclib. After exposure to 1 µM of indicated compound for 24 h, dying cells were stained by propidium iodide (red). Photographs were taken by a Floid imaging station (460× magnification). Representative images of three independent experiments are shown.
