RAC1 and hepatocellular carcinoma: The two studies 34, 35 mutually complement and support our current and previous 9 research in a sense: for one thing, the top connectivity highlighted the possible role of RAC1 in the down‐regulation of miR‐146a‐5p in HCC; for another, the two studies 34, 35 established the validated role of RAC1 in miR‐related HCC and proved the vigorous validity of bioinformatics tools in the present research, rendering us the potential role of RAC1 in miR‐146a‐5p‐related HCC.
