Three Dimensional (3D) conformational change of chromatin organization upon RA mediated Hox PG5 induction

ABSTRACT: Changes in the transcriptional status of developmentally regulated genes, including Hox genes, go along with changes in the chromatin organisation as shown in cultured cells as well as in the developing embryo. The signals that affect the 3D structure of the genome are less understood. The tight regulation of Hox PG5 genes by RA might be accompanied by the physical separation of active and inactive Hox genes in the r5-6 and r8 domains in the hindbrain. To examine the role of RA on higher order chromatin conformation, we employed high-resolution circular chromosome conformation capture followed by high throughput sequencing (4C-Seq). We performed 4C-seq at E14.5, using the Hoxa5 and b5 promoters as view-points on Hox PG5 negative (rhombomers 5-6) and positive domains (rhombomer 8). 4C-seq was also performed with cortex as an entirely Hox negative control tissue.

4C-seq: Temporal dynamics and developmental memory of 3D chromatin architecture at Hox gene loci

Project description:Hox genes are essential regulators of embryonic development. They are activated in a temporal sequence following their topological order within their genomic clusters. Subsequently, states of activity are fine-tuned and maintained to translate into domains of progressively overlapping gene products. While the mechanisms underlying such temporal and spatial progressions begin to be understood, many of their aspects remain unclear. We have systematically analyzed the 3D chromatin organization of Hox clusters in vivo, during their activation using high-resolution circular chromosome conformation capture (4C-seq). Initially, Hox clusters are organized as single 3D chromatin compartments decorated with bivalent chromatin marks. Their progressive transcriptional activation is associated with a dynamic bi-modal 3D organization, whereby the genes switch one after the other, from an inactive to an active 3D compartment. These local 3D dynamics occur within a larger constitutive framework of interactions within the surrounding Topological Associated Domains, which confirms previous results that regulation of this process in primarily cluster intrinsic. The local step-wise progression in time can be stopped and memorized at various body levels and hence it may accounts for the various chromatin architectures previously described at different anterior to posterior body levels for the same embryo at a later stage.

Proteomics of Resistance to Halo Blight in Common Bean

Project description:Phaseolus vulgaris was inoculated with water, and Pseudomonas syringae pv phasiolicola R5 (avirulent) and R8 (virulent) and sampled 24 h later. Tags 126, 127N, and 128C were assigned to water-treated control replicates; tags 129C, 130N, and 131 were assigned to R8-inoculated (susceptible) replicates; and tags 127C, 128N and 130C were assigned to R5-inoculated (resistant) replicates.

A Switch Between Topological Domains Underlies HoxD Genes Collinearity in Mouse Limbs (4C-Seq)

Project description:During limb development, Hoxd genes are transcribed in two waves: Early on, when the arm and forearm are specified and subsequently, when digits form. While the latter phase is controlled by enhancers centromeric to the HoxD cluster, we show here that the early phase requires enhancers located in the opposite telomeric gene desert. The transition between the two types of regulations involves a functional switch between two distinct topological domains, as reflected by a subset of genes mapping centrally into the cluster, which initially interact with the telomeric domain and subsequently shift to establish new contacts on the opposite side. This transition between two regulatory landscapes generates an intermediate area of low Hox dose developing into the wrist, the transition between our arms and our hands. This intriguing correspondence between genomic and morphological boundaries illustrates the mechanism underlying collinear Hox gene regulation in our developing appendages.

Multimodal Hox5 activity generates motor neuron diversity [RNA-seq]

Project description:Motor neurons (MNs) are the final output of circuits driving fundamental behaviors, such as respiration and locomotion. Hox proteins are essential in generating the MN diversity required for accomplishing these functions, but the transcriptional mechanisms that enable Hox paralogs to assign distinct MN subtype identities despite their promiscuous DNA binding motif are not well understood. Here we show that Hoxa5 can modify chromatin accessibility in all mouse spinal cervical MN subtypes and engages TALE co-factors to directly bind and regulate subtype-specific genes. We identify a paralog-specific interaction of Hoxa5 with the phrenic MN-specific transcription factor Scip and show that heterologous expression of Hoxa5 and Scip is sufficient to suppress limb-innervating MN identity. We also demonstrate that phrenic MN identity is stable after Hoxa5 downregulation and identify Klf proteins as potential regulators of phrenic MN maintenance. Our data identify multiple modes of Hoxa5 action that converge to induce and maintain MN identity.
