The expression profile of miRNA in response to IFN-γ-driven ferroptosis in melanoma


ABSTRACT: Anti-PD-1 immunotherapy has been established to be greatly effective in melanoma treatment, but the low response rate and occurrence of treatment resistance significantly hinder its efficacy. Recent studies have demonstrated that IFN-γ secreted by tumor-infiltrating CD8+T cells suppresses the expression of Xc- system to induce ferroptosis of tumor cells. However, whether the escape of tumor cells from ferroptosis facilitates the resistance to immunotherapy and the upstream regulatory mechanism remain elusive. MiRNAs participate in ferroptosis execution and can be delivered systemically by nanoparticle or alternative carriers, through which obvious therapeutic effect on cancer has been obtained. Herein, through RNA sequencing, we first obtained miRNAs expression profile of melanoma cells in IFN-γ-potentiated ferroptosis.
