A study of pancreatic cancer showed that circRNA-FOXK2 is significantly overexpressed in pancreatic cancer cells and tissues and can act as a sponge for miR-942, thereby promoting the expression of ANK1, GDNF, and PAX6, which in turn promote cell growth and migration via cell cycle progression and apoptosis. This evidence concerns the gene ANK1 and familial pancreatic carcinoma.
