To identify cell lines that express TG2, we quantified TG2 by qPCR and western blot analysis in a panel of eight human ovarian cancer cell lines, finding it variable but with good consistency between transcript and protein levels for each cell line except for the TOV3041G cell line which has less TG2 protein expression than is predicted by the mRNA transcript levels, potentially due to intrinsic differences in translational regulation (Figures 1A, B). This evidence concerns the gene TGM2 and ovarian cancer.
