Concordant with the in silico data suggesting LINC00261 association with EMT, only TGFβ-responsive lung and pancreatic cancer cell lines significantly downregulated LINC00261 expression upon exposure to TGFβ-1 for 24, 48, and 72 h (Figure 4f). This evidence concerns the gene TGFB1 and familial pancreatic carcinoma.
