Liu et al. (2017) reported that SP1 could bind to the promoter region of SNHG14 to unregulate its expression in clear cell renal cell carcinoma (ccRCC). Enhanced expression of lncRNA SNHG14 promoted cell migration and invasion by promoting N-WASP protein level. Wu et al. (2016) found that SP1 was a direct target of miR-429, which was able to inhibit cell proliferation, migration, and invasion. This evidence concerns the gene SP1 and nonpapillary renal cell carcinoma.
