MiD49 suppresses the growth and metastasis of pancreatic cancer (PC) cells in vivo. (A) MiD49 expression was determined by qPCR and western blot analyses in SW1990 cells (MiD49, expression vector encoding MiD49; EV, empty vector). (B) Tumor growth curves of the two groups of MiD49 and EV are shown. (C) Harvested tumors and their weights were compared between the two groups. Scale bar, 1 cm. (D) The expression level of MiD49 was determined by immunohistochemical (IHC) staining in tumor tissues from the two groups of MiD49 and EV. Scale bars, 10 µm. (E) Ki-67 staining by IHC analysis in tumor tissues from the two groups of MiD49 and EV. Scale bars, 10 µm. (F) Incidence of pulmonary metastasis in the two groups of MiD49 and EV. MiD49, mitochondrial dynamics protein of 49 kDa. *P<0.05.
