MCF10A cells were plated on slides pre-coated with laminin. Cells were treated for 60 minutes with either EtOH, DMSO, 25uM 4HNE, 5uM RSL3, 4HNE and 10uM KRIBB1 or RSL3 and KRIBB11. Cells were stained for total HSF1 and counterstained with DAPI. Images were taken at 20x magnification. Scale bar is 50 microns. Shown is one replicate of three independent experiments (n=3).
