1 Upregulation of STAT3 level ameliorated the inhibitive effects of miR-4458 on cells proliferation and PD-L1 expression in cells. mir-4458 signal transducer and activator of transcription 3 Sus scrofa
2 For in vivo studies, overexpression of miR-4458 hindered tumor growth, decreased the proportion of PD-1+ T cells, the expression of PD-L1 and IL-10, upregulated the proportion of CD4+ T, CD8+ T cells as well as the expression of IFN-gamma and IL-2, which were all reversed by overexpression of STAT3, and the effects of STAT3 were counteracted after knockdown of PD-L1. mir-4458 signal transducer and activator of transcription 3 Sus scrofa
