Additionally, the authors speculate that lncRNA CASC7 inhibits miR-26, inhibits ASPN, inhibits TGF-β, and promotes XIAP, to activate the SMAD/XIAP pathway in EC, thus improving survival and the invasiveness of endometrial cancer cells [33] PRELP protein may function as a molecule anchoring basement membranes to the underlying connective tissue [34]. Here, AGO2 is linked to endometrial cancer.
