Core Tip

Core Tip: Gastric cancer (GC) is primarily treated with oxaliplatin-based chemotherapy. Patients who receive chemotherapy often develop resistance. Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a novel oncogene. Recent studies suggested that CIP2A is linked to chemoresistance in various cancers. The purpose of this study was to look into the relationship between CIP2A expression and oxaliplatin resistance in GC. The findings revealed that GC tissues have higher CIP2A expression than matched adjacent normal gastric tissues, and CIP2A expression plays an important role in the chemoresistance of GC, suggesting a new treatment strategy for GC.
