miRNA isolation and 454 sequencing from N2 whole worms (Piano project, Kim subgroup)


small RNAs (<200 bp) were isolated from N2 whole worms and sequenced on the Roche 454 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.
