Fig. 3: Flow cytometric analysis and in vivo tumorigenesis assay.

a, b Flow cytometry analysis was carried out to determine the changes in the cell cycle profile following circCTNNA1 knockdown or overexpression in SW620 and SW480 cells. c SW620 cells stably transfected with overexpression or SW480 transfected with shRNA vector were subcutaneously injected into female nude mice. d, e The tumor weight and volume were significantly increased in the circCTNNA1 overexpression group, and decreased in the sh-circCTNNA1 group. f IHC staining were conducted and IHC scores were calculated to determine the effects of circCTNNA1 on the expression of FOXM1 and downstream related proteins in xenograft tumor tissues. ***p < 0.001.
