Project description:Here we introduce a test for lineage-specific selection of cis-regulation that can be applied to any gene set of interest. Applying the test to hundreds of gene sets in two diverged subspecies of mouse, we find evidence for selection acting on the cis-regulation of several functional classes, including those involved in both physiology (e.g. mitochondria-related genes and growth regulators) and behavior (e.g. locomotory-related genes and memory-related genes). These positively selected gene sets implicate potential targets of positive selection that are supported by quantitative trait loci, and accurately predict a number of phenotypic differences between the two subspecies, suggesting that the divergence in these traits may have been driven by adaptive evolution.
Project description:We explored the relationship between the evolutionary dynamics of CTCF binding and the functional stability of higher order genome structures, by performing ChIP-seq experiments in closely related Mus species or strains and intersecting with Hi-C-derived topologically associating domains (TADs) and expression data. All experiments were performed in adult male liver samples in 3 biological replicates and with an input control set. We also generated RAD21 (cohesin subunit) ChIP-seq from a replicate of adult male mouse (C57BL/6J) liver to determine localization of cohesin with respect to CTCF.
Project description:We have identified candidate genes from the Feml2 QTL influencing femur length through allele specific expression analysis of growth plates in C57BL/6J x CAST/EiJ F1 hybrids. This work provides the foundation to identify novel genes affecting bone geometry.
Project description:Sequencing files provided here are mouse liver RNA-seq in two mouse strains: C57BL/6J and CAST/EiJ. This is part of a larger study published in PLoS Genetics (2021) "Harnessing natural variation to identify cis regulators of sex-biased gene expression in a multi-strain mouse liver model" that includes DNase-seq and H3K27ac ChIP-seq in mouse liver from the same two strains. This allows us to identify strain-shared ("core") and strain-unique sex-biased genes and enhancers.
