Abstract

Cycloartenyl ferulate (CF) is abundant in brown rice with multiple biological-functions. It has been reported to possess antitumor activity, however, the related action mechanism of action of CF has not been clarified. Herein, we unexpectedly uncover the immunological regulation effects of CF and its molecular mechanism. We discovered that CF directly enhanced the killing capacity of natural killer (NK) cells for various Cancer cells in vitro. In vivo, CF also improved Cancer surveillance in mouse models of lymphoma clearance and metastatic melanoma dependent on NK cells. In addition, CF promoted Anticancer efficacy of the anti-PD1 antibody with improvement of tumor immune microenvironment. Mechanistically, we first unveiled that CF acted on the canonical JAK1/2-STAT1 signaling pathway to enhance the immunity of the NK cells by selectively binding to IFNγ receptor 1 (IFNγR1). Collectively, our results indicate that CF is a promising immunoregulation agent worthy of attention in clinical application in the future. Due to broad biological significance of IFNγ, our findings also provide a capability to understand the diverse functions of CF.
