POMT2 and gastric carcinoma: In line with previous findings of Salomé S. Pinho's group (in collaboration with our group) that in human gastric carcinomas, expression levels of POMT2 correlate with altered structures of N-glycans on E-cadherin (40), we now demonstrate a link between classic O-mannosylation and N-glycosylation of cadherins, which was for the first time analyzed in such depth.
