CD274 and hepatocellular carcinoma: IHC analysis of the in situ HCC tissues demonstrated significant enhancement in SOCS2, STAT5A, STAT5B, α‐SMA, FAP, Ki‐67, and PD‐L1 in specimens with higher miR‐500a‐3p expression and suppression in specimens with lower miR‐500a‐3p expression, while the IHC expression of SOCS2 showed an opposite trend (Figure 6L; Figure S5B, Supporting Information).
