Cardiac Sex Differences in the Transcriptome of C57 Male and Female E9.5 Hearts

Purpose: The goals of this study are to compare E9.5 male and female C57 mouse embryonic hearts transcriptome profiling (RNA-seq) to conclude cardiac sex differences at the mRNA level. Methods: mRNA profiles of E9.5 male and female C57 mouse embryonic hearts were generated by deep sequencing, n=4 for each sex, using Illumina HiSeq2500. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows-Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. Results: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to the mouse genome (build mm10) and identified 16,460 transcripts in the mouse hearts.
