e13007Background: Genetic mutations in Mitofusin-2(MFN2) interrupt mitochondrial fusion and cause the untreatable neurodegenerative condition Charcot-Marie-Tooth disease type 2A(Nature, December 2016). MFN2 was initially identified as a hypertension-associated gene and implicated in the pathogenesis of multiple cancer types. However, underlying mechanisms of MFN2 in lung adenocarcinoma was unclear. Methods: MFN2 expression at protein level was examined in 30 pair lung adenocarcinoma/adjacent normal lung samples with immunohistochemistry staining. Then MFN2 knocked down in human lung adenocarcinoma cells A549 with lentiviral-mediated shRNA strategy. The effects of MFN2 knockdown on cell proliferation, cell cycle process, cell migration and invasion was investigated in A549 cells. MFN2-knockdown induced gene expression changes was analyzed by microarray assay and then functional pathway enrichment analysis was performed to identify critical pathways involved in MFN2-mediated lung adenocarcinoma development....
