Expression profiling by high throughput sequencing
Summary
Previous studies have suggested a strong association between lower MSH3 expression, reduced somatic repeat expansion, and slower disease onset and progression. The effects of a homozygous knock-out in the Msh3 gene on transcriptome phenotypes in striatum in six-month-old WT and zQ175 mice were studied. Striatum was isolated from 6-month-old mice. Transcriptomic analysis (RNASeq) was performed on four genotypes with 8 replicates per genotype: WT (WT for Htt and Msh3), zQ175 (zQ175 for Htt, WT for Msh3), WT.Msh3.HOM (WT for Htt, Homozygous for Msh3 KO), and zQ175.Msh3.HOM (zQ175 for Htt, Homozygous for Msh3 KO).
Overall design
RNASeq analysis was performed on samples from the striatum tissues of 6-month-old mice with one of the following four genotypes: WT, WT.Msh3.HOM, zQ175, zQ175.Msh3.HOM. N = 8 per group (4M/4F except zQ175.Msh3.HOM which had 5M/3F).
