Recently, long noncoding RNAs (lncRNAs) have been emerged as pivotal regulators in various human cancers, including pancreatic ductal adenocarcinoma (PDAC). SPRY4-intronic transcript 1 (SPRY4-IT1) was reported to be upregulated in some kind of human cancers. Here, we elucidated the biological functions and possible clinical values of SPRY4-IT1 on PDAC. In present study, expression of SPRY4-IT1 in PDAC tissues and corresponding normal tissues were explored by qRT-PCR experiments. The link between SPRY4-IT1 expression levels and clinicopathological significance was further analyzed. In addition, the oncogenic role of SPRY4-IT1 was detected both in vitro and in vivo. The results demonstrated that SPRY4-IT1 was abnormally upregulated in PDAC tissues and cell lines. Tumor stage and differentiation grade was closely correlated with SPRY4-IT1 expression. Additionally, decreased SPRY4-IT1 contributed to tumor suppressive effect through attenuating cell growth, clonogenic ability and facilitating apoptosis via Bcl-2/caspase-3 pathway in PANC1 and Capan-2 cells. Furthermore, the xenograft study confirmed the tumor proliferation-promoting role of SPRY4-IT1 in PANC1 cells. Taken together, these findings indicated that SPRY4-IT1 is a potential therapeutic target and prognosis biomarker for the patients with PDAC.
