RHOA and non-small cell lung carcinoma: Based on the above study, we speculated that miR-31-3p may participate in the metastasis of NSCLC by activating the RhoA/ROCK-2 signaling pathway, mainly by verifying the expression of miR-31-3p in NSCLC tissues, and to detect the difference in NSCLC cell function and mechanism when its expression changes in order to provide a target for clinical treatment of NSCLC.
