Mouse Creld1 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Creld1 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Creld1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Creld1 gene (NCBI Reference Sequence: NM_133930 ; Ensembl: ENSMUSG00000030284 ) is located on Mouse chromosome 6. 10 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 10 (Transcript: ENSMUST00000032422). Exon 3~4 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Creld1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-263G9 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Homozygous KO is embryonic lethal: abnormal vasculature and brain and craniofacial development and reduced atrioventricular cushion size at E10.5. Exon 3 starts from about 20.48% of the coding region. The knockout of Exon 3~4 will result in frameshift of the gene. The size of intron 2 for 5'-loxP site insertion: 3493 bp, and the size of intron 4 for 3'-loxP site insertion: 863 bp. The size of effective cKO region: ~1000 bp. The cKO region does not have any other known gene.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

    Pugnaloni et al. Italian Journal of Pediatrics (2020) 46:61 https://doi.org/10.1186/s13052-020-00825-4 REVIEW Open Access Genetics of atrioventricular canal defects Flaminia Pugnaloni1, Maria Cristina Digilio2, Carolina Putotto1, Enrica De Luca1, Bruno Marino1 and Paolo Versacci1* Abstract Atrioventricular canal defect (AVCD) represents a quite common congenital heart defect (CHD) accounting for 7.4% of all cardiac malformations. AVCD is a very heterogeneous malformation that can occur as a phenotypical cardiac aspect in the context of different genetic syndromes but also as an isolated, non-syndromic cardiac defect. AVCD has also been described in several pedigrees suggesting a pattern of familiar recurrence. Targeted Next Generation Sequencing (NGS) techniques are proved to be a powerful tool to establish the molecular heterogeneity of AVCD. Given the complexity of cardiac embryology, it is not surprising that multiple genes deeply implicated in cardiogenesis have been described mutated in patients with AVCD. This review attempts to examine the recent advances in understanding the molecular basis of this complex CHD in the setting of genetic syndromes or in non- syndromic patients. Keywords: Congenital heart disease, Atrioventricular canal defect, Genetics Introduction extracellular matrix, leading to absent or incomplete fu- The atrioventricular canal defect (AVCD), also called sion of ventral (antero-superior) and dorsal (postero-in- atrioventricular septal defect, is a quite common con- ferior) atrioventricular cushions [2–4].

  • The Transcription Factor Sox7 Modulates Endocardiac Cushion
    Hong et al. Cell Death and Disease (2021) 12:393 https://doi.org/10.1038/s41419-021-03658-z Cell Death & Disease ARTICLE Open Access The transcription factor Sox7 modulates endocardiac cushion formation contributed to atrioventricular septal defect through Wnt4/ Bmp2 signaling Nanchao Hong1,2, Erge Zhang1, Huilin Xie1,2,LihuiJin1,QiZhang3, Yanan Lu1,AlexF.Chen3,YongguoYu4, Bin Zhou 5,SunChen1,YuYu 1,3 and Kun Sun1 Abstract Cardiac septum malformations account for the largest proportion in congenital heart defects. The transcription factor Sox7 has critical functions in the vascular development and angiogenesis. It is unclear whether Sox7 also contributes to cardiac septation development. We identified a de novo 8p23.1 deletion with Sox7 haploinsufficiency in an atrioventricular septal defect (AVSD) patient using whole exome sequencing in 100 AVSD patients. Then, multiple Sox7 conditional loss-of-function mice models were generated to explore the role of Sox7 in atrioventricular cushion development. Sox7 deficiency mice embryos exhibited partial AVSD and impaired endothelial to mesenchymal transition (EndMT). Transcriptome analysis revealed BMP signaling pathway was significantly downregulated in Sox7 deficiency atrioventricular cushions. Mechanistically, Sox7 deficiency reduced the expressions of Bmp2 in atrioventricular canal myocardium and Wnt4 in endocardium, and Sox7 binds to Wnt4 and Bmp2 directly. Furthermore, 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; WNT4 or BMP2 protein could partially rescue the impaired EndMT process caused by Sox7 deficiency, and inhibition of BMP2 by Noggin could attenuate the effect of WNT4 protein. In summary, our findings identify Sox7 as a novel AVSD pathogenic candidate gene, and it can regulate the EndMT involved in atrioventricular cushion morphogenesis through Wnt4–Bmp2 signaling.

This capacity has largely been ascribed to paracrine factors secreted by nerve-resident Schwann cells. Here, we used single-cell transcriptional profiling to identify ligands made by different injured rodent nerve cell types and have combined this with cell-surface mass spectrometry to computationally model potential paracrine interactions with peripheral neurons. These analyses show that peripheral nerves make many ligands predicted to act on peripheral and CNS neurons, in- cluding known and previously uncharacterized ligands. While Schwann cells are an important ligand source within injured nerves, more than half of the predicted ligands are made by nerve-resident mesenchymal cells, including the endoneurial cells most closely associated with peripheral axons. At least three of these mesen- chymal ligands, ANGPT1, CCL11, and VEGFC, promote growth when locally applied on sympathetic axons.

Molecular Genetic Analysis of CRELD1 in Patients with Heterotaxy Disorder by Samaneh Zhian A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Biology Thesis Committee: Deborah Duffield, Chair Cheryl Maslen Suzanne Estes Portland State University ©2011 ABSTRACT Heterotaxy refers to the abnormal arrangement of internal organs in relation to each other. Model organism studies have shown that functions of more than eighty genes are required for normal asymmetric left-right organ development. CRELD1 has been shown to be necessary for proper heart development and mutations in CRELD1 are known to increase risk of cardiac atrioventricular septal defects (AVSD). AVSD is the most common form of heart defect associated with heterotaxy, and we have previously shown that some individuals with heterotaxy-related AVSD have mutations in CRELD1 . Therefore, we propose to examine the CRELD1 gene in a large sample of patients with heterotaxy syndrome.

ABSTRACT (150 words) The assembly of neurotransmitter receptors in the endoplasmic reticulum limits the number of receptors delivered to the plasma membrane, ultimately controlling neurotransmitter sensitivity and synaptic transfer function. In a forward genetic screen conducted in the nematode C. elegans, we identified crld-1 as a gene required for the synaptic expression of ionotropic acetylcholine receptors (AChR). We demonstrated that the CRLD-1A isoform is a membrane-associated ER-resident protein disulfide isomerase (PDI). It physically interacts with AChRs and promotes the assembly of AChR subunits in the ER. Mutations of Creld1, the human ortholog of crld-1a, are responsible for developmental cardiac defects.
