SNAI2 and cancer: Consistently, analysis of the RNA-seq data from another independent study (GSE92250) also showed that ELF3-AS1 knockdown led to SNAI2 mRNA upregulation in the A549 and Hela cell lines (Fig. 5I), suggesting the negative regulation of SNAI2 expression by ELF3-AS1 might be widely in cancers [22].
