RGS16 regulated by let-7c-5p promotes glioma progression by activating PI3K-AKT pathway

Frontiers of Medicine 2023, Volume 17, Issue 1,   Pages 143-155 doi: 10.1007/s11684-022-0929-y

Abstract: Moreover, previous studies confirmed that let-7c-5p, a well-known microRNA, can act as a tumour suppressorMoreover, RGS16 was validated as a direct target gene of miR let-7c-5p.The overexpression of miR let-7c-5p obviously downregulated the expression of RGS16, and knocking downmiR let-7c-5p had the opposite effect.Thus, we suggest that the suppression of RGS16 by miR let-7c-5p can promote glioma progression and may
