Clinicopathological and prognostic significance of myofibrillogenesis regulator-1 protein expression in pancreatic ductal adenocarcinoma.

Myofibrillogenesis regulator-1 (MR-1) expression was detected in different malignancies and is associated with poor prognosis. However, its role in pancreatic ductal adenocarcinoma (PDAC) has not been fully elucidated. Thus, the aim of this study was to investigate the association of MR-1 expression with clinicopathologic features and prognosis in patients with PDAC.

Sunitinib reverse multidrug resistance in gastric cancer cells by modulating Stat3 and inhibiting P-gp function.

Sunitinib, a small-molecule multi-targeted tyrosine kinase inhibitor, has been applied in phase II clinical trial as second-line treatment for advanced gastric cancer. In this study, we determined the effect of Sunitinib on the multidrug resistance in gastric cancer cells selected by vincristine. Our results showed that Sunitinib significantly enhanced the cytotoxicity of adriamycin, vincristine, etoposide, 5-Fluorouracil, and cisplatin in multidrug-resistant gastric cancer cells (SGC7901/VCR).
