a The cell proliferation test with CCK-8 reagent indicated that overexpression of PDX1, EN2, and MSX1 promotes proliferation of the HCT116 colon cancer cell line. The overexpression of each gene was verified through FLAG-tag capture. b Transwell invasion assays with HCT116 cells overexpressing PDX1, EN2, and MSX1 were conducted, and invading cells were stained with crystal violet. Overexpression of PDX1, EN2, and MSX1 was found to accelerate migration and confer invasive properties.
