LINC00641 and renal cell carcinoma: To determine the molecular mechanism by which LINC00641 mediated RCC cell proliferation and invasion, the online database (http://starbase.sysu.edu.cn/starbase2/index.php) was used to predict the potential target miRNAs that could bind with the LINC00641 sequence and miR-340-5p was selected as the best potential target of LINC00641 (Fig. 3a).
