Abstract

Adhesion of cancer cells to the extracellular matrix (ECM) causes a novel acquired chemotherapeutic drug‑resistant phenotype, referred to as cell adhesion-mediated drug resistance (CAM-DR). Our previous studies suggested that the adhesion molecule MGr1-Ag/37LRP may promote multidrug resistance in gastric cancer cells. Therefore, we investigated MGr1-Ag/37LRP binding-induced adhesion, and its role in CAM-DR. Initial studies revealed that, after adhesion to the ECM, the multidrug-resistant gastric cancer cell lines SGC7901/VCR and SGC7901/ADR showed significantly higher mean adhesive cell numbers than non‑resistant SGC7901 cells. We then investigated expression of MGr1-Ag/37LRP in gastric cancer cells adhering to laminin. Western blotting, RT-PCR and dual-luciferase reporter assays showed that laminin induced MGr1-Ag/37LRP expression and activity. In vitro and in vivo assays revealed that small interfering RNA against MGr1-Ag/37LRP significantly reduced CAM-DR in SGC7901/VCR cells. In vivo and in vitro analyses revealed that binding of MGr1-Ag/37LRP decreased intracellular drug accumulation by increasing P-glycoprotein and multidrug-associated protein expression, and inhibited drug-induced apoptosis by regulating Bcl-2 and Bax expression. These results indicate that MGr1-Ag/37LRP contributes to laminin-mediated CAM-DR in gastric cancer cells, and is a potentially effective target for reversing this phenomenon in gastric cancer.
