STAT3 and hepatocellular carcinoma: found that miR‐500a‐3p promoted the characteristics and tumorigenicity of cancer stem cells in HCC through the STAT3 signaling pathway.[18] Consistent with these findings, we observed miR‐500a‐3p upregulation in HCC tissues and cells and that miR‐500a‐3p overexpression was associated with poorer OS and disease‐free survival in patients with HCC.
