NLGN1 and nonpapillary renal cell carcinoma: In order to profoundly investigate the underlying molecular mechanism of NLGN1-AS1 regulation of ccRCC, we predicted three potential conjugated miRNAs of NLGN1-AS1 with Mirdb (http://www.mirdb.org/), PITAR (https://pictar.mdc-berlin.de/), and DIANA (http://diana.imis.athena-innovation.gr/) (Figure 4A).
