miRNA isolation and Illumina sequencing from N2 mixed-stage whole worms (Piano project, Kim subgroup)


small RNAs (<200 bp) were isolated from mixed-stage N2 whole worms and sequenced on the Illumina platform, and aligned to the WS190 genome using MegaBlast.

Series Description

The 3' untranslated region (3'UTR) constitutes a major site of post-transcriptional regulation of gene expression. Sequence elements in the 3'UTR interact with trans-acting regulators such as microRNAs that affect translation and stability. The overall aim is to use a 3'RACE cloning-sequencing stragety to identify the 3'UTRs of C. elegans transcripts and explore their heterogeneity in different developmental stages and tissues.
