Surprisingly MSLN was also detected at high levels in the duodenal papillotubular adenocarcinoma cell line TGBC18TKB and at moderate levels in the gastric signet ring carcinoma line Kato III, bladder transitional cell carcinoma line JMSU1, gall bladder carcinoma line TGBC2TKB and even weakly in the ovarian epitheloid line HeLa (Fig. 2). Here, MSLN is linked to bladder transitional cell carcinoma.
