摘要: CD133 on cancer stem cells is a potential therapeutic target. In this study, antibody (CD133mAb) treatment resulted in cell death hepatoma LM3, HepG2, Hep3B and Huh-7 cells, especially under low glucose condition. The also inhibited formation of spheroids, colonies, xenograft tumors. Ectopic enabled hepatocyte L02 to be suppressed by CD133mAb increased spheroid formation. caused primary HCC sensitized them Doxorubicin Cisplatin. effect was attributed suppressing autophagy promoting necrotic death. Therefore, targeting condition approach for hepatocarcinomas.
