RT Journal Article SR Electronic T1 Luteolin-regulated MicroRNA-301-3p Targets Caspase-8 and Modulates TRAIL Sensitivity in PANC-1 Cells JF Anticancer Research JO Anticancer Res FD International Institute of Anticancer Research SP 723 OP 731 DO 10.21873/anticanres.14003 VO 40 IS 2 A1 SOKVISETH MOENG A1 SEUNG WAN SON A1 HYUN AH SEO A1 JONG SUN LEE A1 CHUNG KWON KIM A1 HYO JEONG KUH A1 JONG KOOK PARK YR 2020 UL http://ar.iiarjournals.org/content/40/2/723.abstract AB Background/Aim: MicroRNAs (miRNAs) play regulatory roles in pancreatic ductal adenocarcinoma (PDAC). However, it is still required to identify the function of miRNA-301-3p in pancreatic cancer cells. Materials and Methods: Effects of luteolin on cell growth, TRAIL cytotoxicity, and miR-301-3p levels were evaluated. The role of miRNA-301-3p in regulating cell proliferation, target gene expression, and TRAIL cytotoxicity were studied. Results: The levels of miR-301-3p were down-regulated in PANC-1 cells exposed to luteolin, which inhibits the growth of PANC-1 cells and sensitizes cells to TRAIL. The knockdown of miR-301-3p attenuates cell proliferation and enhances TRAIL cytotoxicity. In addition, caspase-8 was directly targeted by miR-301-3p. Conclusion: Our findings unveil a critical biological function of miR-301-3p in regulating cell proliferation and elevating an antiproliferative effect of TRAIL on cancer cells. Our observation of miR-301-3p/caspase-8 relationship can also serve to clarify the role of miR-301-3p in other cancer types and related diseases.
