Long noncoding RNAs (lncRNAs) have been emerged as critical regulators of gene expression at epigenetic, transcriptional and post-transcriptional level, yet what genes are regulated by lncRNAs remains to be characterized. To assess the effects of a specific lncRNA on gene expression, increasing researchers profiled the genome-wide or individual gene expression level changes after knocking down or overexpressing the lncRNA. However, no online repository is currently available to collect these differentially expressed genes regulated by lncRNAs.
To make it convenient for researchers to know what genes are regulated by a lncRNA or which lncRNAs regulate a given gene of interest, researchers at the Harbin Institute of Technology have developed LncRNA2Target: a comprehensive resource of differentially expressed genes after lncRNA knockdown or overexpression.
In this database system, target genes of a lncRNA are defined as the differentially expressed genes after knocking down or overexpressing the lncRNA. By reviewing all published lncRNA papers, we manually curated the differentially expressed target genes confirmed by qRT-PCR or western blot, and identified all the differential target genes from the microarray or RNA-seq data.
