Cyclophilin B promotes cell proliferation, migration, invasion and angiogenesis via regulating the STAT3 pathway in non-small cell lung cancer

This study aimed to investigate the role and regulatory mechanism of CypB in NSCLC progression. The expression levels of CypB was detected in NSCLC samples and cell lines by ELISA, western blot and immunohistochemistry assay. In addition, CCK8, colony formation, scratch and transwell assays were used to evaluate the proliferation, migration and invasion of A549 cells with CypB silencing. The expression of angiogenesis related proteins and pathway-related factors were detected by western blot. In NSCLC samples, CypB expression was upregulated. The expression of CypB was significantly reduced in the siRNA-cyclophilin B group. In addition, CypB silencing inhibited cell proliferation, migration and invasion. The expression of angiogenesis related proteins and pathway-related factors have also changed significantly. These findings suggested that CypB silencing may suppress the proliferation, invasion, migration and angiogenesis of A549 cells via inhibiting STAT3 pathway.
