XIST and familial pancreatic carcinoma: For example, lncRNA SNHG5 facilitated growth and invasion of melanoma by regulating the miR-26a-5p/TRPC3 pathway [41]; lncRNA OIP5-AS1 predicted poor prognosis and regulated cell proliferation and apoptosis in bladder cancer [42]; lncRNA XIST enhanced pancreatic cancer cells invasion through promotion of TGF-β2 expression by targeting miR-141-3p [43].
