PRDM15 mutation prevents forebrain development through an Otx2 pathway

Project description:Acquiring correct brain anatomy and function requires extensive morphogenesis and patterning, which is regulated by a complex gradient of transcription factors. Members of the PR domain containing (PRDM) chromatin-modulating family of transcriptional regulators function in neuronal specification and brain patterning. Little is known about the function of PRDM15, even though it is predicted to have a role in the development of the central nervous system, and lies in the Down syndrome trisomy region of HSA21 and MMU16. Here, we show that PRDM15 is required for forebrain development and repression of hindbrain gene expression. The phenotype of Prdm15 mutants mimics that of Otx2 loss. Using RNA sequencing, we found that a PRDM15 dependent molecular pathway, which includes many homeodomain factors that pattern the forebrain, including OTX2 and PAX6, is disrupted in Prdm15 mutants. Consistent with the role of OTX2 as a master regulator of forebrain development, which represses rostral expansion of the hindbrain to maintain the brain rostro-caudal axis, conditionally inactivating PRDM15 in the forebrain also truncates the forebrain and disrupts the brain rostro-caudal axis. PRDM15 co-expresses with OTX2 in cells of the primordial anterior forebrain, a region where OTX2 is known to function, and PRDM15 binds to the Otx2 promoter, suggesting it may directly impact Otx2 expression. These findings place PRDM15 in the forebrain transcriptional hierarchy for the first time, revealing that PRDM15 is a candidate for pathogenesis in Down syndrome or other neurodevelopmental disorders.

Early limb bud transcriptome analysis between anterior and posterior domain

Project description:Shh signal mediated by Gli family of transcription factors regulates digit growth and patterning in early limb development. Shh expression in the posterior margin of the limb bud defines the zone of polarizing activity. However, much less is know about downstream targets that mediate Shh signal functions. In this dataset, we include the expression data obtained from dissected anterior and posterior halves of mouse limb bud respectively. These data are used to obtain 889 transcripts that were upregulated 1.3 fold or more in the posterior limb bud, and 1189 transcripts that were enriched in the anterior limb bud at 1.3 fold or more. Two samples were analyzed. We generate pairwise comparisons between anterior and posterior limb tissues. Genes with a fold-change ≥1.3 were selected.

Single-cell transcriptomics illuminates anterior-posterior patterning of the mesoderm in Drosophila embryos at gastrulation

Project description:Single-cell technology was used to investigate dynamic transcriptional changes in the blastula and gastrula of Drosophila embryos. Cells from embryo of stages 5 to 9 were isolated and subjected to library construction. Mesoderm cells were labeled with mCD8-GFP utilizing the GAL/UAS system. PCA identified 12 unique cell clusters that represent the blastoderm, mesoderm, endoderm and ectoderm anlage, primordia, and a sampling of differentiating cell types. In the cellular blastoderm, we found that the major wave of zygotic gene activation consists of two steps, which is supported by sub-clustering analysis. Trajectory analysis of stage 6-8 mesoderm cells suggested that transcription factors, previously linked to ectodermal segment polarity, also control mesoderm segmentation, patterning and differentiation. With the cells originating from the posterior ventral region of the blastoderm, trajectory analysis identified a group of cells that are multipotent progenitors giving rise to visceral muscles, Malpighian tubules as well as a new cell type. In summary, this single-cell study of gastrulation demonstrates early patterning involves trunk- versus pole-centered programs, the mesoderm is segmentally patterned, and a new cell type arises from the caudal mesoderm.

Molecular characterization of chick anterior and posterior half-scleorotomes by RNA-sequencing.

Project description:During amniote peripheral nervous system development, segmentation ensures the correct patterning of the spinal nerves relative to vertebral column. Along the antero-posterior (rostro-caudal) axis, each somite-derived half-sclerotome has intrinsic molecular properties that govern this segmentation process. Posterior half-sclerotomes express repellent molecules to restrict axon growth and neural crest migration to anterior half-sclerotomes. Here, we report an RNA-sequencing-based molecular characterization of anterior and posterior half-sclerotomes, using the chick embryo as a model organism.

Transcriptional trajectories highlight the transition from anterior-posterior to proximal-distal patterning in the early limb bud [scRNA-seq]

Project description:Limb patterning relies in a large part on the function of the Hox family of developmental genes. While the differential expression of Hox genes shifts from the anterior-posterior (A-P) to the proximal-distal (P-D) axis around embryonic day 11 (E11), whether this shift coincides with a more global change of P-D versus A-P patterning program remains unclear. By performing and analyzing the transcriptome of the developing limb bud from E10.5 to E12.5, at single cell resolution, we have uncovered transcriptional trajectories which revealed a general switch from A-P to P-D genetic program between E10.5 and E11.5. Interestingly, the transcriptional trajectories at E10.5 all end with cells expressing either proximal or distal markers suggesting a progressive acquisition of P-D identity. Moreover, we observed that distally expressed Hox genes, namely Hoxa13 and Hoxd13, act as a key determinant for P-D patterning as their transcriptional control results in their distal restricted expression, which in turn restricts Hoxa11 in the proximal limb bud domain, in progenitor cells of the zeugopod. Finally, we identified three categories of genes expressed in the distal limb mesenchyme characterized by distinct temporal expression dynamics. As anticipated from previous results, HOX13 binding was observed within or in the neighborhood of several of these genes consistent with previous evidence suggesting that the transition from the early/proximal to the late/distal transcriptome of the limb mesenchyme largely relies on HOX13 function.
