Fig. 2From: Augmented expression of cardiac ankyrin repeat protein is induced by pemetrexed and a possible marker for the pemetrexed resistance in mesothelioma cellsCARP and IGFBP3 were differentially expressed in PEM-resistant cells. Expression of six candidate molecules in parent and PEM-resistant cells (PEM) were examined with Western blot analysis. Cell lysates were probed with antibody as indicated. Tubulin-α was used as a loading control. Dotted arrow indicates a non-specific signal and arrows shows authentic IGFBP3 signalsBack to article page
