Genome-wide expression analysis of Caenorhabditis elegans AXIN mutant

Purpose: The goal of this study is to identify differentially expressed genes in pry-1/Axin mutant compare to N2 wild-type (WT). Our study represents the first analysis of Axin transcriptome in C. elegans and facilitates investigations of axin mediated processes. Whole animal total RNA was extracted from L1 synchronized worms and mRNA profiles of WT and pry-1(mu38) animals were generated by paired end deep sequencing, using Illumina HISeq 2000. The sequence reads that passed quality filters were analyzed using ce6 with Burrows–Wheeler Aligner (BWA) followed by eXpress to estimate transcript abundances. Differentially-expressed genes were called at a false discovery rate (FDR) of 0.05% using the DESeq package in R.
