Yao et al. identified circ_0030167, a key molecule derived from BMMSC-EVs, which inhibits the invasion, migration, proliferation, and stemness of pancreatic cancer cells by sponging miR-338-5p and targeting the Wif1/Wnt8/β-catenin axis [156]. The gene discussed is WIF1; the disease is familial pancreatic carcinoma.
