BACKGROUND The Par complex - comprising partition-defective 6 (Par6), Par3, and atypical protein kinase C (aPKC) - is crucial for cell polarisation, the loss of which contributes to cancer progression. Transforming growth factor β (TGFβ)-induced phosphorylation of Par6 on the conserved serine 345 is implicated in epithelial-to-mesenchymal transition (EMT)(More)
Defective regulation of the alternative pathway of the complement system is believed to contribute to damage of retinal pigment epithelial (RPE) cells in age-related macular degeneration. Thus we investigated the effect of complement activation on the RPE cell membrane by analyzing changes in membrane conductance via patch-clamp techniques and Ca2+ imaging.(More)
The reaction patterns of eight antibodies directed against blood group substances A, B and H, respectively, against Lewis B antigen, difucosylated carbohydrate antigens (DFCA), gastrointestinal cancer antigen CA 19-9 (GICA), carcinoma-associated antigen CA-50 and CEA, were studied in 68 rectal carcinomas using the avidin-biotin-peroxidase method.
