Abstract
Aim: Blocking lipogenesis could significantly inhibit the progression of pancreatic cancer. Exploring the regulatory mechanisms of lipogenesis by lncRNA SNHG16 might be of great significance to control the development of pancreatic cancer. Methods: The proliferation, migration, invasion and lipogenesis were determined with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, wound healing, transwell and Oil Red O staining assays, respectively. The interactions among lncRNA SNHG16, miR-195 and SREBP2 were analyzed by dual luciferase reporter assays. Results: Both the knock down of lncRNA SNHG16 and SREBP2 and overexpression of miR-195 suppressed the proliferation, migration, invasion and lipogenesis in pancreatic cancer cells. LncRNA SNHG16 directly sponged miR-195 to modulate the lipogenesis via regulating the expression of SREBP2. Conclusion: LncRNA SNHG16 accelerated the development of pancreatic cancer and promoted lipogenesis via directly regulating miR-195/SREBP2 axis.
