Cleft lip and cleft palate (CL/P) in Esrp1 KO mice is associated with alterations in Wnt signaling and epithelial-mesenchymal crosstalk

ABSTRACT: To investigate the molecular mechanisms that lead to CL/P in Esrp1-/- mice, we performed RNA-Seq using RNAs collected from both epithelial cells and mesenchymal cells from control and Esrp1-/- embryos. We used a previously described method to separate facial ectoderm and mesenchyme from facial prominences at E12.0, a stage at which lip fusion is underway (Li and Williams, 2013). We collected pooled paired ectoderm and mesenchyme samples to obtain sufficient material for four replicates each of ectoderm and mesenchyme fractions from WT and Esrp1-/- embryos and prepared total RNA for RNA-Seq. We used paired end sequencing and obtained deep coverage with an average of 100 million read pairs per replicate. Preliminary analysis of transcripts per million (TPM) values in the RNA-Seq analysis from epithelial and mesenchymal control samples validated that they were derived from relatively pure populations of each cell type using a panel of standard epithelial and mesenchymal cell type-specific markers, including Esrp1

Ectoderm and mesenchyme gene expression in the developing mouse face

Project description:This investigation provides a robust multi-dimensional compendium of gene expression data relevant to mouse facial development. It profiles the transcriptome ofectoderm and mesenchyme from the three facial prominences in a time series encompassing their growth and fusion. Analysis of the dataset identified more than 8000 differentially expressed genes comprising dramatically different ectoderm and mesenchyme programs. The mesenchyme programs included many genes identified in earlier analyses as well hundreds of genes not previously implicated in craniofacial development. The ectoderm programs included over a thousand genes that highlight epithelial structure, cell-cell interactions and signaling. The dataset includes 45 .cel files, DABG probability and RMA log2 expression values for each probeset, and statistics for 9457 probesets representing 8575 genes. 45 total samples, with 15 conditions sampling three ages (E10.5, E11.5, E12.5), three facial prominences (mandibular, maxillary and fronto-nasal) and two tissue layers (ectoderm or mesenchyme), with 3 biological replicates per condition. Differential expression was determined after median filter for variance with three-way ANOVA, Benjamini-Hochberg multiple testing correction

A gene expression atlas of early craniofacial development

Project description:We present a gene expression atlas of early mouse craniofacial development. Laser capture microdissection (LCM) was used to isolate cells from the principal critical micro-regions, whose development, differentiation and signaling interactions are responsible for the construction of the mammalian face We examined the facial mesenchyme and adjacent neuroepithelium at E8.5, at E9.5 we obtain cells from the facial mesenchyme, olfactory placode/epidermal ectoderm, underlying neuroepithileium, and emerging mandibular and maxillary arches. AT E10.5 we sampled the medial and lateral prominences, olfactory pit, multiple regions of the underlying neuroepithelium the mandibular and maxillary arches, and Rathke's pouch. Mouse emrbyos were harvested at developmental stage E8.5 , E9.5, and E10.5 and cells were captured from microregions responsible for the construction of the mammalian face. RNA was extracted, labelled, and quantified using the Mouse ST-l microarray.

The Molecular Anatomy of Mammalian Upper Lip and Primary Palate Fusion at Single Cell Resolution

Project description:The mammalian lip/primary palate form when coordinated growth and morphogenesis bring the nasal and maxillary processes into contact, the epithelia co-mingle, remodel and clear from the fusion site to allow mesenchyme continuity. Although several genes required for fusion have been identified, an integrated molecular and cellular description of the overall process is lacking. Here we employ single cell RNA sequencing of the developing mouse face to identify ectodermal, mesenchymal, and endothelial populations associated with patterning and fusion of the facial prominences. This analysis indicated that key cell populations at the fusion site exist within the periderm, basal epithelial cells and adjacent mesenchyme. Overall, these data provide a comprehensive high-resolution description of the various cell populations participating in fusion of the lip/primary palate as well as formation of the nasolacrimal groove, and they furnish a powerful resource for those investigating the molecular genetics of facial development and facial clefting that can be mined for critical mechanistic information concerning this prevalent human birth defect.

Knockout mice reveal an essential role for Epithelial splicing regulatory proteins (Esrps) in mammalian development and epithelial splicing in vivo

Project description:Tissue- and cell-type specific regulators of alternative splicing (AS) are an essential layer of posttranscriptional gene regulation necessary for normal cellular function, patterning, and development. Here we report the Epithelial splicing regulatory proteins (Esrps) are required for patterning of multiple organs, with loss of both paralogs, Esrp1 and Esrp2, resulting in increasingly severe phenotypes. Global profiling of the Esrp splicing regulatory network from total epidermis revealed varied splicing sensitivity of Esrp targets upon loss of Esrp1 or double knockout. This may explain the progressive phenotypes seen in Esrp knockout mice, and these mice provide a unique genetic tool to evaluate functional consequences of epithelial splicing events in vivo. RNA from purified total epidermis (basal keratinocyte layer to cornified layer) of E18.5 mouse embryos were harvested by Trizol extraction. (Esrp1+/+, Esrp2-/- (n=2), Esrp1-/-, Esrp2+/+ (n=3), Esrp1-/-, Esrp2+/- (n=2), and Esrp1-/-, Esrp2-/- (n=2). 1 ug of total RNA was used for for RNA-seq library preparation using the TruSeq™ Stranded mRNA LT Sample Prep Kit (Illumina). 100x2 bp paired-end RNA-seq reads were generated on a HiSeq 2000 sequencer.

Snail-dependent epithelial splicing regulatory protein 1 (ESRP1) silencing drives malignant transformation of human pulmonary epithelial cells [miRNA]

Project description:The significance of epithelial-to-mesenchymal transition (EMT)-inducing transcription factors in the onset of non-small cell lung cancer has not been resolved. Here, we report increased Snail expression in pulmonary premalignant lesions relative to histologically normal-appearing pulmonary epithelium. Utilizing immortalized human pulmonary epithelial cells and isogenic derivatives, we document Snail-dependent anchorage-independent growth of the epithelial cells in vitro, as well as transformation, primary tumor growth, and metastatic behavior in vivo. Epithelial splicing regulatory protein 1 (ESRP1) tumor suppressor silencing was a requirement for Snail-driven transformation in vivo, and we identified ESRP1 loss in Snail-expressing pulmonary premalignant lesions in situ. Snail drives these and other carcinogenic signaling programs in an ALDH+CD44+CD24- pulmonary stem cell subset in which ESRP1 and stemness-repressing micro-RNAs are inhibited.

Expression data from mesodermal Tbx1-knockout otic vesicles and periotic mesenchyme at E11.5

Project description:The T-box transcription factor Tbx1 is expressed in the otic vesicle and surrounding periotic mesenchyme during inner ear development. Mesenchymal Tbx1 is essential for inner ear development, with conditional mutants displaying defects in both auditory and vestibular systems. We have previously identified reduced expression of retinoic acid metabolic genes in the periotic mesenchyme of mesoderm conditional Tbx1 mutants, using the T-Cre mouse line, implicating retinoic acid in mesenchymal-epithelial signaling downstream of Tbx1 in the periotic mesenchyme. In order to identify downstream effectors of mesenchymal-epithelial signaling downstream of mesenchymal Tbx1, we have utilized a gene profiling approach comparing embryonic day 11.5 otic vesicle and surrounding periotic mesenchyme from T-Cre-mediated conditional Tbx1 mutants (Mest-KO) and conditional heterozygous control litter mates (control). This data was used in conjunction with OV-only data (GSE34064) to identify expression changes within the periotic mesenchyme. E11.5 T-Cre-mediated conditional Tbx1 mutants (Mest-KO) and control (T-Cre conditional Tbx1 heterozygotes) embryos were microdissected to isolate the otic vesicle and surrounding periotic mesenchyme. Left and right ears from 3 embryos of the same genotype were pooled for each chip, and 3 biological replicates of each chip were performed.

Project description:We present a gene expression atlas of early mouse craniofacial development. Laser capture microdissection (LCM) was used to isolate cells from the principal critical micro-regions, whose development, differentiation and signaling interactions are responsible for the construction of the mammalian face. We examined the facial mesenchyme and adjacent neuroepithelium at E8.5, at E9.5, facial mesenchyme, olfactory placode/epidermal ectoderm, underlying neuroepithileium, and emerging mandibular and maxillary arches. AT E10.5 we sampled the medial and lateral prominences, olfactory pit, multiple regions of the underlying neuroepithelium the mandibular and maxillary arches, and Rathke's pouch. For these 103 samples, laser capture microdissection from serial and bioreplicated E8.5, E.9.5, and E10.5 frozen sections was used to make RNA using the ZR RNA MicroPrep kit (Zymo). Nugen RiboSpia Ovation Pico WTA System V2 was used target amplification. We used starting total RNA of at least 2 ng.

Transcriptomic Analysis of PNN- and ESRP1-regulation in Human Corneal Epithelial Cells

Project description:Pnn depletion in developing mouse corneal epithelium led to disrupted alternative splicing of multiple ESRP-regulated epithelial-type exons. In human corneal epithelial cells (HCET), ESRP1 and PNN displayed close localization in and around nuclear speckles and their physical association in protein complexes was identified. In this study, gene expression profiling was performed to identify PNN- and ESRP1-regulated alternative pre-mRNA splicing in human corneal epithelial cells. Immortalized human corneal epithelial cells harboring doxycycline-inducible shRNA against PNN or ESRP1 were created. Whole transcriptome array analysis on ESRP1 or PNN knockdown HCET cells revealed clear alterations in transcript level and splicing pattern of specific subsets of genes with significant overlaps in their candidate targets. Our data suggest that ESRP1 and PNN modulate alternative splicing of a specific subset of exons, but not general splicing events. ESRP1 and PNN may together participate in the regulation of epithelial-specific splicing program in a genome-wide fashion. Parental HCET, shRNA-PNN HCET, and shRNA-ESRP1 HCET cells were cultured for 3 days with/without doxycycline. Total RNA was isolated from four biological replicates of each sample group and then subjected to hGlue3_0 transcriptome array analysis.
