Improving Estimates of Compensatory cis-trans Regulatory Divergence.

ABSTRACT: Interspecific hybrids have played a key role in research on gene expression regulation. A growing number of studies have measured genome-wide allele-specific expression in hybrids and observed that cis-regulatory changes often oppose trans-acting changes affecting the same genes, suggesting stabilizing selection for compensatory changes. However, the most common method for estimating these effects is biased, producing artifactual patterns of compensatory evolution. Here I introduce a simple modification leveraging biological replicates that ameliorates the bias.

Conservation of mouse-human trans-regulatory circuitry despite high cis-regulatory divergence

Project description:The basic body plan and major physiological axes have been highly conserved during mammalian evolution, yet only a small fraction of the human genome sequence appears to be subject to evolutionary constraint. To quantify cis- versus trans-acting contributions to mammalian regulatory evolution, we performed genomic DNase I footprinting of the mouse genome across 25 cell and tissue types, collectively defining ~8.6 million transcription factor (TF) occupancy sites at nucleotide resolution. Here we show that mouse TF footprints conjointly encode a regulatory lexicon that is ~95% similar with that derived from human TF footprints. However, only ~20% of mouse TF footprints have human orthologues. Despite substantial turnover of the cis-regulatory landscape, nearly half of all pairwise regulatory interactions connecting mouse TF genes have been maintained in orthologous human cell types through evolutionary innovation of TF recognition sequences. Furthermore, the higher-level organization of mouse TF-to-TF connections into cellular network architectures is nearly identical with human. Our results indicate that evolutionary selection on mammalian gene regulation is targeted chiefly at the level of trans-regulatory circuitry, enabling and potentiating cis-regulatory plasticity. We performed genomic DNase I footprinting of the mouse genome across 25 cell and tissue types, collectively defining ~8.6 million transcription factor (TF) occupancy sites at nucleotide resolution.

Human gene regulatory evolution is driven by divergence in cis and trans

Project description:Gene regulation can evolve either by cis-acting local changes to regulatory element DNA sequences or by global changes to the trans-acting regulatory environment; however, the modes favored during recent human evolution are unknown. To date, studies investigating gene regulatory divergence between closely-related species have produced limited estimates on the relative contributions of cis and trans effects on DNA regulatory element activities at a global-scale. By leveraging a comparative ATAC-STARR-seq framework, we identified 10,779 regulatory regions with divergent activity in cis and 10,608 regulatory regions with divergent activity in trans between human and rhesus macaque lymphoblastoid cell lines (LCLs). This revealed substantially more trans effects than predicted and indicates trans-regulatory mechanisms play a larger role in human evolution than previously expected. We also discover that most species-specific regulatory elements (67%) diverge in both cis and trans, suggesting these two mechanisms jointly drive divergent regulatory activity in a single sequence.

Compensatory cis-trans regulation of mouse liver gene expression

Project description:Two inbred mouse strains, C57BL/6J and CAST/EiJ, were crossed to generate both initial and reciprocal F1 crosses. For each genetically distinct class of mice (F0 C57BL/6J, F0 CAST/EiJ, F1i - C57BL/6J x CAST/EiJ, F1r - CAST/EiJ x C57BL/6J, where the male parent is listed first), samples were collected from a single lobe of the liver from 6 male mice between the ages of 4 and 6 months. The 24 samples were then processed to generate strand-specific RNA-seq libraries, which were sequenced on the Illumina GAII platform using 72bp paired-end reads.

Cis- and trans- regulatory divergence between progenitor species determines gene-expression novelty in Arabidopsis allopolyploids

Project description:Gene-expression divergence between species shapes morphological evolution, but the molecular basis is largely unknown. Here we show cis- and trans-regulatory elements and chromatin modifications on gene-expression diversity in genetically tractable Arabidopsis allotetraploids. In Arabidopsis thaliana and Arabidopsis arenosa, both cis and trans with predominant cis-regulatory effects mediate gene-expression divergence. The majority of genes with both cis- and trans-effects are subjected to compensating interactions and stabilizing selection. Interestingly, chromatin modifications correlate with cis - and trans -regulation. In F1 allotetraploids, Arabidopsis arenosa trans factors predominately affect allelic expression divergence. Arabidopsis arenosa trans factors tend to upregulate Arabidopsis thaliana alleles, whereas Arabidopsis thaliana trans factors up- or down-regulate Arabidopsis arenosa alleles. In resynthesized and natural allotetraploids, trans effects drive expression of both homoeologous loci into the same direction. We provide evidence for natural selection and chromatin regulation in shaping gene-expression diversity during plant evolution and speciation.
