eri-1 (mg366)

miRNA isolation and 454 sequencing from eri-1(mg366) young adult whole worms (Piano project, Kim subgroup)


small RNAs (<200 bp) were isolated from eri-1(mg366) young adult 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.
