Computational Identification of microRNA-17-3p in Breast Cancer Cells.

Background: MicroRNAs (miRNAs) are small, highly conserved non-coding RNA molecules involved in the RNA silencing and post-transcriptional regulation of gene expression. miRNAs are well conserved in both plants and animals, and are thought to be a vital and evolutionarily ancient component of gene regulation and also act as oncogenes or tumor suppressors. It is known that Express Sequence Tags (EST) are a short sub-sequence of cDNA sequence, which contain information of condition or tissue specific transcripts (coding and non-coding) of an organism.
