Abstract

Curcumenol, an effective ingredient of Wenyujin, has been reported that exerted its antitumor potential in a few Cancer types. However, the effect and molecular mechanism of curcumenol in lung Cancer are largely unknown. Here, we found that curcumenol induced cell death and suppressed cell proliferation in lung Cancer cells. Next, we demonstrated that Ferroptosis was the predominant method that contributed to curcumenol-induced cell death of lung Cancer in vitro and vivo for the first time. Subsequently, using RNA sequencing, we found that the long non-coding RNA H19 (lncRNA H19) was significantly downregulated in lung Cancer cells treated with curcumenol, when compared to untreated controls. Overexpression of lncRNA H19 eliminated the Anticancer effect of curcumenol, while lncRNA H19 knockdown promoted Ferroptosis induced by curcumenol treatment. Mechanistically, we showed that lncRNA H19 functioned as a competing endogenous RNA to bind to miR-19b-3p, thereby enhanced the transcription activity of its endogenous target, ferritin heavy chain 1 (FTH1), a marker of Ferroptosis. In conclusion, our data show that the natural product curcumenol exerted its antitumor effects on lung Cancer by triggering Ferroptosis, and the lncRNA H19/miR-19b-3p/FTH1 axis plays an essential role in curcumenol-induced ferroptotic cell death. Therefore, our findings will hopefully provide a valuable drug for treating lung Cancer patients.
