Small RNA target genes
5,929 (GSE3008), 4,032 (GSE6682), and 7,696 (GSE5228) genes were predicted to be post-transcriptionally regulated by small RNAs since their transcribed regions are targets by at least one smallRNA in antisense orientation. 3,325 genes are common to all three datasets and a total number of 9,166 different genes are predicted targets of small RNAs in antisense orientation. The complete lists of genes predicted to be down-regulated by small RNAs can be downloaded as text files: 5929.txt; 4032.txt; 7696.txt; 3325.txt; 9166.txt.
