In order to elucidate whether miR‐203a‐3p.1 is related to cancer metastasis by down‐regulation of IL‐24, HCC cells were transfected with miR‐203a‐3p.1 mimics or IL‐24, and cell migration and metastasis were assayed with Transwell chambers. The gene discussed is IL24; the disease is hepatocellular carcinoma.
