Survival analysis of pancreatic cancer samples showed that low expression of UCA1, TM4SF1-AS1, LINC00941, DNMBP-AS1, and CASC8 improved OS more than high expression, whereas high expression of SNHG10 and SOCS2-AS1 improved OS more than low expression (P < 0.001, Supplementary Fig. S5A). This evidence concerns the gene TM4SF1 and familial pancreatic carcinoma.
