MCF10A cells were pretreated for 15 minutes with either DMSO, EtOH, or 10uM BIRB, followed by 60 minutes with either DMSO, EtOH, 25uM 4HNE, 5uM RSL3, 4HNE and BIRB or RSL3 and BIRB. Isolated protein was assessed by immunoblotting for prominin2, phospho-p38 (Thr180/Tyr182) and total p38. Shown is one replicate of three independent experiments (n=3).
