Moreover, the transfection of <i>miR-378a-3p</i> mimics into Li-7 and HuH-7 cells effectively decreased the PD-L1 mRNA and protein expression levels, and inhibited Treg differentiation in co-culture models by modulating the expression levels of certain cytokines. Furthermore, the overexpression of <i>miR-378a-3p</i> hindered cell proliferation and migration but facilitated apoptosis by repressing STAT3 signaling in HCC cells.
