Functionally, Kindlin-1 promoted colorectal cancer (CRC) cell proliferation in vitro and tumor growth in vivo, and was also required for CRC cell migration and invasion via an epithelial to mesenchymal transition.
The effects of kindlin-1 on the proliferation, migration and invasion of pancreatic cancer cells were investigated using an RNA interference technique.
Overexpression of kindlin-1 induced changes indicating epithelial-mesenchymal transition and transforming growth factor beta (TGFβ) signaling, constitutive activation of cell motility, and invasion (number of migrating cells, Kindlin-1 cells vs control, mean = 164.66 vs. 19.00, difference = 145.6, 95% CI = 79.1 to 212.2, P = .004; invasion rate, Kindlin-1-cells vs control = 9.65% vs. 1.92%, difference = 7.73%, 95% CI = 4.75 to 10.70, P < .001).
