Emx2 underlies the development and evolution of marsupial gliding membranes

ABSTRACT: We study the genomic and developmental basis of the mammalian gliding membrane, or patagium, an adaptative trait that has repeatedly evolved in different lineages, including in closely related marsupial species. Through comparative genomic analysis of fifteen new marsupial genomes, both from gliding and non-gliding species, we find that the Emx2 locus experienced lineage-specific patterns of accelerated cis-regulatory evolution in gliding species. We confirm our finding via epigenomics, transcriptomics, and in vivo marsupial transgenics.

Expression data from Emx2 wildtype and knockout olfactory epithelium

Project description:Emx2 is a homeobox transcription factor that plays a critical role in development. Olfactory sensory neuron axons from Emx2 knockout mice fail to innervate their target tissue, the olfactory bulb. Homeobox transcription factors may also play an important role in olfactory receptor expression. We used microarrays to analyze differences in mRNA abundance in the olfactory epithelium of Emx2 wildtype and knockout embryonic day 18.5 mice. Keywords: Knockout-Wildtype comparision Total RNA from 9 Emx2 wildtype and 9 Emx2 knockout mice was analyzed. Equal amounts of RNA from 3 animals was pooled to create one biological sample, 3 pools per genotype, 6 chips total. RNA was hybridized to the Affymetrix Mouse Exon 1.0 ST array.

Transcription profiling of mouse Emx2 knock-out urogenital epithelium

Project description:Series of samples studying effect of knock out Emx2 in urogenital epithelium of mouse embryos at E10.5. Experiment Overall Design: The epithelial cells of the gonadal primordium were obtained by Laser Microdissection System. The specimens prepared from three individuals were mixed as one pool. There are three experimental replicates in each genotype, 3-pools of wild-type and 3-pools of Emx2 KO mouse.

Emx2 defines bidirectional polarity of neuromasts by changing hair-bundle orientation and not hair-cell positions

Project description:The bidirectional sensitivity of neuromasts to water flow in the zebrafish lateral line system is attributed to the opposite orientation of the hair bundles on top of sensory hair cells (HC) within a neuromast. After each HC precursor divides to form two nascent HCs, HCs of the same bundle orientation are positioned on one side of the neuromast, across from HCs with opposite bundle orientation. The transcription factor emx2 is expressed in only one of the sibling HCs. Loss or gain of function of emx2 in HCs causes unidirectional hair bundle orientation in neuromasts. It is not clear whether Emx2 is required specifically in establishing hair bundle orientation after HC formation or Emx2 has an earlier role in HC fate and/or positioning, which indirectly changes hair bundle orientation. A phenomenon, in which nascent sibling HCs exchange positions with each other, has been postulated to be the mechanism for HCs to acquire their designated positions within the neuromast. We asked whether Emx2 is involved in positional acquisition of HCs within the neuromast. Using live-imaging and our emx2 reporter we find that the HC rearrangement, redefined as two processes named Rock & Roll are required for HCs to acquire their positions. Although Emx2 regulates the duration of the Rock and the frequency of Roll of nascent HCs, it is not required for their positional acquisition. Instead, Emx2 regulates the morphology of nascent HCs, which facilitates the rearrangement process.

Epithelial planar bipolarity emerges from Notch- mediated asymmetric inhibition of Emx2

Project description:This dataset consists of single-cell RNA-seq (mcSCRBseq) data of neuromast hair cells from wild type and Emx2 mutant zebrafish larvae. Posterior lateral-line neuromast hair cells were isolated by fluorescence activated cell sorting (FACS) from the dissociated trunks of wild type and Emx2-mutant Tg[myo6b:actb1-EGFP] transgenic zebrafish larvae expressing the green fluorescent protein EGFP in hair cells and unipotent hair-cell progenitors (UHCPs).

Gene regulatory dynamics during craniofacial development in a carnivorous marsupial

Project description:Marsupials and placental mammals exhibit significant differences in reproductive and life history strategies. Marsupials are born highly underdeveloped after an extremely short period of gestation, leading to prioritization of the development of structures critical for post-birth survival in the pouch. Critically, they must undergo accelerated development of the oro-facial region compared to placentals. Previously we described the accelerated development of the oro-facial region in the carnivorous Australian marsupial, the fat-tailed dunnart Sminthopsis crassicaudata that has one of the shortest gestations of any mammal. By combining genome comparisons of the mouse and dunnart with functional data for the enhancer-associated chromatin modifications, H3K4me3 and H3K27ac, we investigated divergence of craniofacial regulatory landscapes between these species. While genes involved in regulating facial development were largely conserved in mouse and dunnart, the regulatory landscape varied significantly. Additionally, a subset of dunnart-specific enhancers were associated with genes highly expressed only in dunnart relating to cranial neural crest proliferation, embryonic myogenesis and epidermis development. Comparative RNA-seq analyses of facial tissue revealed dunnart-specific expression of genes involved in the development of the mechanosensory system. Accelerated development of the dunnart sensory system likely relates to the sensory cues received by the nasal-oral region during the postnatal journey to the pouch. Together these data suggest that accelerated development in the dunnart can be driven by dunnart-specific enhancer activity. Our study highlights the power of marsupial-placental comparative genomics for understanding the role of enhancers in driving temporal shifts in development.
