ELOVL2 Knockout

Download

By generating CRISPR-mediated elovl2 knockout, we are planning to study the crucial role of elovl2 for multi-tissue synthesis of 22:6n-3 in vivo. Endogenously synthesized PUFAs are important for transcriptional regulation of lipogenic genes in Atlantic salmon. This study demonstrates key roles of elovl2 at two penultimate steps of PUFA synthesis in vivo and suggests Srebp-1 as a main regulator of endogenous PUFA synthesis in Atlantic salmon.

RNAseq

Stranded RNAseq libraries were prepared from 1µg total RNA from liver tissue using TruSeq Stranded mRNA library preparation kit (Illumina, San Diego, USA) using double unique indices (#20022371), according to the manufacturer's instruction (Part 15031057 Rev.E). Libraries were sequenced at the Norwegian Sequencing Centre (NSC). All libraries were pooled, and the same pool was sequenced on 4 flow cell lanes on a HiSeq 3000 machine (Illumina), generating 100bp single-end reads.

Sanger sequencing

The three different CRISPR target sites within the elovl2 gene (T1-3) were characterised by Sanger sequencing, sequencing on average 8 clones per individual.
