Identification of intermediate-size non-coding RNAs involved in the UV-induced DNA damage response in C. elegans.

ABSTRACT:

Background

A network of DNA damage response (DDR) mechanisms functions coordinately to maintain genome integrity and prevent disease. The Nucleotide Excision Repair (NER) pathway is known to function in the response to UV-induced DNA damage. Although numbers of coding genes and miRNAs have been identified and reported to participate in UV-induced DNA damage response (UV-DDR), the precise role of non-coding RNAs (ncRNAs) in UV-DDR remains largely unknown.

Methodology/principal findings

We used high-throughput RNA-sequencing (RNA-Seq) to discover intermediate-size (70-500 nt) ncRNAs (is-ncRNAs) in C. elegans, using the strains of L4 larvae of wild-type (N2), UV-irradiated (N2/UV100) and NER-deficient mutant (xpa-1), and 450 novel non-coding transcripts were initially identifie
