Suppression of SNAIL2, a zinc finger protein member of the SNAIL superfamily of epithelial-mesenchymal transition-inducing transcription factors (EMT-TFs) commonly overexpressed in pancreatic cancer patients, restored sensitivity of pancreatic cancer cell lines KLM1 and KMP5 to chemotherapy drug gemcitabine through an IGF binding protein 2 (IGFBP2)-dependent mechanism in vitro and in vivo (50). This evidence concerns the gene SNAI1 and familial pancreatic carcinoma.
