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:Retinoic acid (RA), the bioactive derivative of vitamin A, is essential for vertebrate heart development. Both excess and reduced RA signaling lead to cardiovascular malformations, particularly affecting the cardiac outflow tract (OFT). The cellular mechanisms underlying the effects of RA signaling during OFT morphogenesis are not fully understood. To address this question, we used transient maternal RA supplementation to rescue the early lethality resulting from inactivation of the murine retinaldehyde dehydrogenase 2 (Raldh2) gene. By embryonic day 13.5, Raldh2-/- hearts exhibited OFT septation defects. Although cardiac neural crest cells (cNCC) were present in OFT cushions of Raldh2-/- mutant embryos, we observed that cNCC were ectopically located in the peripheral region of the endocardial cushions, closer to the myocardium rather than immediately subjacent to the endocardium. Mislocated cNCC were aligned in parallel instead of perpendicular arrays to the endocardial surface within the proximal OFT. Supernumerary mesenchyme was generated both in and ex vivo within the cushions by Raldh2-/- mutant endocardium and found in place of the cNCC in a subendocardial, medial position. Although mislocated and misoriented, mutant cNCC resembled wildtype cells in their compaction density and individually elongated shape. Our data show that RA signaling acts on cNCC orientation relative to the septation plane and position within OFT cushions during septation process. Transcriptomic analysis and pathway-specific readout suggest that up-regulation of the Bmp pathway may be responsible for increased endothelial-to-mesenchymal transition, leading thereby to displacement of cNCC. E10.5 stage embryonic mouse outflow tracts were microdissected. Four pools of four outflow tracts were established for wildtype (WT) and mutant (Raldh2-/-) embryos derived from dams whose food had been supplemented with all-trans-RA (Sigma) directly mixed into powdered food at 0.1 mg/g food and offered between E7.5 and E8.5. Total RNA was extracted using Macherey-Nagel NucleoSpin® RNA columns without on-column DNase digestion.

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:A high concentration of maternal retinoic acid (RA), the active derivative of vitamin A, is well known as a teratogenic agent which can cause developmental defects. Our previous studies have shown that the maternal administration of RA to mice within a narrow developmental window induces outflow tract (OFT) septum defects, which closely resembles human transposition of the great arteries (TGA), although the responsible factors and pathogenic mechanisms of the TGA induced by RA still remain unknown. To identify the candidate genes involved in the altered development of the OFT in RA-induce TGA model, we isolated the RNA from E9.5 control and RA-treated OFT regions, and performed a microarray analysis. Approximately 200 outflow tract region were isolated from control and RA-treated embryos (embryonic day 9.5). We sought to obtain the candidate genes involved in the altered development of the OFT in RA-induce heart defects.

Project description:Heart development is known to be influenced by haemodynamics, however the effects of abnormal load on gene expression are not clearly defined. To determine the hearts transcriptional response to stress, a model of haemodynamic alteration, outflow tract (OFT) banding, was employed in the chick embryo at HH21. Stereological and expression analysis were performed at HH29, with targeted expression studies at HH35. We defined a phenotype of left sided heart dilation and performed RNA sequencing on OFT-banded hearts compared to Sham controls. Globin transcripts were depleted in the RNA during library preparation, and 28 differentially expressed genes were identified. Expression appeared to represent a mechanism of cardioprotection with calcium sequestering, metabolic and developmental genes highlighted. Significant reductions in apoptosis were also seen. We have presented a model of left sided dilation in OFT-banded hearts and found differential expression of genes that may be associated with stress and maintaining cardiac output.

Project description:The transcription factor Nkx2.5 is required for specification of pharyngeal arch second heart field (SHF) progenitors that contribute to outflow tract (OFT) and right ventricle (RV) formation. Multiple sets of microarray data were analyzed to identify genes that are candidate targets of Nkx2.5 in the second heart field. These sets are: 1) publicly available data for cardiothoracic tissue from E9.5 Nkx2.5 wild-type, heterozygous and homozygous embryos; 2) an analysis of mouse E10.5 pharyngeal arch tissue; 3) an analysis of mouse E12.5 heart tissue; and 4) a temporal analysis of the cardiogenic cell line P19CL6. This combined analysis identified 11 genes (Lrrn1, Elovl2, Safb, Slc39a6, Khdrbs1, Hoxb4, Fez1, Ccdc117, Jarid2, Nrcam, and Enpp3) expressed in SHF-containing pharyngeal arch tissue whose regulation is dependent on Nkx2.5 expression.
