Repression precedes independent evolutionary gains of a highly specific gene expression pattern

ABSTRACT: This study addresses how activator and repressor sequences evolve and interact during enhancer evolutiom in the context of a fatty acyl-CoA elongase gene that contributes to pheromone production in Drosophila. The highly specific tissue expression of the gene in the ejaculatory bulb resulted from the initial evolution of a repressor sequence prior to the independent evolution of an activator sequence.

Evolved Repression Overcomes Enhancer Robustness

Project description:Biological systems display extraordinary robustness. Robustness of transcriptional enhancers results mainly from clusters of binding sites for the same transcription factor, and it is not clear how robust enhancers can evolve loss of expression through point mutations. Here, we report the high-resolution functional dissection of a robust enhancer of the shavenbaby gene that has contributed to morphological evolution. We found that robustness is encoded by many binding sites for the transcriptional activator Arrowhead and that, during evolution, some of these activator sites were lost, weakening enhancer activity. Complete silencing of enhancer function, however, required evolution of a binding site for the spatially restricted potent repressor Abrupt. These findings illustrate that recruitment of repressor binding sites can overcome enhancer robustness and may minimize pleiotropic consequences of enhancer evolution. Recruitment of repression may be a general mode of evolution to break robust regulatory linkages.

Repression precedes independent evolutionary gains of a highly specific gene expression pattern.

Project description:Highly specific expression patterns can be caused by the overlapping activities of activator and repressor sequences in enhancers. However, few studies illuminate how these sequences evolve in the origin of new enhancers. Here, we show that expression of the bond gene in the semicircular wall epithelium (swe) of the Drosophila melanogaster male ejaculatory bulb (EB) is controlled by an enhancer consisting of an activator region that requires Abdominal-B driving expression in the entire EB and a repressor region that restricts this expression to the EB swe. Although this expression pattern is independently gained in the distantly related Scaptodrosophila lebanonensis and does not require Abdominal-B, we show that functionally similar repressor sequences are present in Scaptodrosophila and also in species that do not express bond in the EB. We suggest that during enhancer evolution, repressor sequences can precede the evolution of activator sequences and may lead to similar but independently evolved expression patterns.

Protein-coding changes preceded cis-regulatory gains in newly evolved transcription circuit

Project description:While changes in both the coding-sequence of transcriptional regulators and in the cis-regulatory sequences recognized by them have been implicated in the evolution of transcriptional circuits, little is known of how they evolve in concert. We describe an evolutionary pathway in fungi where a new transcriptional circuit (a-specific gene repression by Matα2) evolved by coding changes in an ancient master regulator followed millions of years later by cis-regulatory sequence changes in the genes of its future regulon. We discerned this order of events by analyzing a group of species in which the coding changes in the regulator are present, but the cis-regulatory changes in the target genes have not yet occurred. In this group we show that the coding changes became necessary for the regulator’s deeply conserved function and were therefore preserved. We propose that the changes first arose without altering the overall function of the regulator (although changing the details of its mechanism) and were later co-opted to “jump start” the formation of the new circuit.

NAB2-STAT6 Gene Fusions in Solitary Fibrous Tumor by Integrative Sequencing

Project description:<p>Transcriptome sequencing of solitary fibrous tumors / hemangiopericytomas from a variety of anatomic sites revealed recurrent gene fusions between two genes, NAB2 and STAT6. All SFTs examined exhibited an in-frame fusion transcript encoding a fusion protein containing the EGR1 interaction domain of NAB2 with the transcriptional activation domain of STAT6. Functional testing of the fusion alleles confirmed the conversion of the wt NAB2 repressor into a transcriptional activator. A range of individual fusion junctions can be detected by next-generation sequencing acro the sample set, highlighting the suitability of this method in the diagnostic characterization of SFTs. This study indentified the pathognomonic alteration in solitary fibrous tumors and illuminates a pathway towards targeted therapeutics for this cancer.</p>

H3K27ac in WT and Shh-/-, and Shh-/-;Gli3-/- E10.5 limb buds

Project description:Purpose: The response to Hedgehog signaling in the limb is driven by GLI bound enhancers. While most Hh targets in the developing limb bud appear to be regulated by the activity of GLI-repressor, the role of GLI activator in this regulation is unclear. Here we assess the roles of GLI activator and repressor in regulating H3K27ac to activate their enhancers. Methods: ChIP-seq was performed in Embryonic day 10.5 mouse limb buds from WT, Shh-/- and Shh-/-Gli3-/- embryos Results: We found that most GLI binding regions can be activated in the absence of both GLI activator and repressor, while a small subset require GLI activator for activity. These indicate that most GLI enhancers in the limb are regulated by GLI repression.

THE DNA BINDING LANDSCAPE OF THE MAIZE AUXIN RESPONSE FACTOR FAMILY [DAP-seq]

Project description:DAP-seq was used to generate genome-wide DNA:TF interaction maps for fourteen maize ARFs from the evolutionarily conserved class A ‘activator’ and class B ‘repressor’ clades. Among the distinct binding sites that were identified, we observed a high degree of overlap for ARFs of the same class, but found substantial differences in motif sequence, spacing, site preference, and association with auxin induced genes among clade A and clade B ARFs.
