miR-200c inhibits TGF-β-induced-EMT to restore trastuzumab sensitivity by targeting ZEB1 and ZEB2 in gastric cancer

Gastric cancer is the fifth most common malignancy in the world, with Eastern Asia as one of areas with the highest incidence rates. Trastuzumab, a HER2-targeting antibody, combined with chemotherapy has been successfully employed for the gastric cancer patients with HER2 overexpression/amplification. However, trastuzumab resistance is a major problem in clinical practice. Here we observed that the trastuzumab-resistant gastric cancer cell line...
