Project description:Purpose: The goal of this study was to evaluate changes in the transcriptome profile during periocular neural crest differentiation into corneal endothelium and keratocytes. Methods: RNA profiles of chick embryonic day (E3) periocular neural crest, E5 corneal endothelium, and E7 corneal endothelium plus keratocytes were generated in triplicate by deep sequencing using Illumina HS4000. Bowtie2 and HISAT were used to map clean reads to reference gene and genome, respectively. An average mapping ratio of 76.26% to the reference gene and 93.10% to the genome were generated with Galgal5 reference assembly.Transcripts were normalized and presented as Fragments Per Kilobase Million (FPKM). Differentially expressed genes between pNCvsEn and pNCvsKEn were examined. Expression of some candidate genes was validated by in situ hybridization. Results: 790 transcripts were enriched between pNC and En, and 865 transcripts were enriched between pNC and KEn. Enriched transcripts correspond with KEGG pathways involved in cell proliferation, synthesis of extracellular matrix, focal adhesion, metabolism, and cancer. The RNA-Seq data serves as platform for further analyses of the molecular networks involved in NCC differentiation into corneal cells, and provides insights into genes involved in corneal dysgenesis and adult diseases.

Project description:To investigate the gene expression in human corneal epithelial overexpressing hsa-miR-145 by transfection , we have employed Whole Human Genome Oligo Microarray (Agilent) as a screening platform to identify gene regulation. We discovered a differential gene expression in HCE cells transfected with hsa-mIR-145 against cells with scrambled sequences. Among them, genes related with corneal development, integrity, differentiation and inflammatory responses were found and this was validated by real-time PCR. HCE cells transfected with hsa-miR-145 or scrambled sequences were collected at 24 hours after transfection. Total RNA was extracted by Trizol/chloroform and purified with RNeasy mini spin column. RNA samples with 28S/18S ratios in the range of 1.4 to 1.8 were used for expression RNA profiling using Whole Human Genome Oligo Microarray (Agilent).

Project description:Neural crest defects lead to congenital heart disease involving outflow tract (OFT) malformation. Integrin-linked-Kinase (ILK) plays important roles in multiple cellular processes and embryogenesis. ILK is expressed in neural crest cells (NCC), but its role in NCC and OFT morphogenesis remains unknown. We used microarrays to detail the global programme of gene expression underlying the morphogenesis of the cardiac neural crest and outflow tract. The outflow tract of control and ILK mutant mouse embryos at E10.5 were dissected and dissociated. Neural crest cells were FACS sorted and used for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Cranial neural crest cells (NCC) give rise to the majority of the cartilage, bone, connective tissue, and sensory ganglia in the head, and also participate in the remodeling of the cardiac outflow tract and pharyngeal arch arteries during cardiovascular development. Our preliminary results show that targeted deletion of focal adhesion kinase (FAK) in murine NCC results in cardiovascular and craniofacial alterations, resembling human congenital heart diseases The objective of this project is to elucidate the underlying mechanisms by which FAK mediates NCC function during development. Compare gene expression in cranial neural crest cells of E11.5 wild type and FAK mutants. FAK is a tyrosine kinase that transduces integrin and growth factor signaling pathways. Abnormal growth factor signaling leads to cardiovascular malformations caused by deficient cardiac NCC function. However, a direct role for FAK in NCC morphogenesis has not been demonstrated. We will test the hypothesis that FAK is a downstream target of essential growth factor signaling in cranial neural crest cells during development. 1) Generate E11.5 mouse embryos that are either control (FAK+/flox) or NCC specific FAK knockout (Wnt1Cre;FAKflox/flox). 2) Determine genotype by PCR. 3) Dissect head and torax from the different genotypes. 4) Obtain NCC from dissected tissue by magnetic cell sorting using p75 antibody. 5) Prepare total RNA from speciments. We will pool the NCC from 3 different embryos of the same genotype, and send total RNA to TGEN for probe preparation, hybridization and array result analysis.

Project description:Combining an in vitro hNCC differentiation protocol with epigenomic profiling, we provide the first whole-genome characterization of cis-regulatory elements in this highly relevant cell type. With this data at hand, we have characterized the chromatin state and dynamics of all human gene promoters during the course of NCC in vitro differentiation. Most importantly, we have identified a large cohort of active and NCC-specific enhancers, which we showed to be functionally relevant in vivo, in the context of embryonic development. Finally, through sequence analysis of the identified NCC enhancers, we uncovered the orphan nuclear receptors NR2F1 and NR2F2 as novel hNCC transcriptional regulators both in vitro and in vivo.
