In an in vivo mouse xenograft model, these miRNAs significantly decreased the tumorigenicity of colon cancer cells, suggesting that miR‐342‐5p and miR‐608 inhibit proliferation and metastasis by downregulating ARD1 expression, highlighting the important role of miRNAs in regulating ARD1 and its downstream signaling pathways [33]. The gene discussed is NAA10; the disease is malignant colon neoplasm.
