Identification of signaling pathways that specify a subset of migrating enteric neural crest cells at the wavefront in mouse embryos. Dev Cell 2024; 59:1689-1706.e8. [PMID: 38636517 DOI: 10.1016/j.devcel.2024.03.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 01/17/2024] [Accepted: 03/25/2024] [Indexed: 04/20/2024]
Abstract
During enteric nervous system (ENS) development, pioneering wavefront enteric neural crest cells (ENCCs) initiate gut colonization. However, the molecular mechanisms guiding their specification and niche interaction are not fully understood. We used single-cell RNA sequencing and spatial transcriptomics to map the spatiotemporal dynamics and molecular landscape of wavefront ENCCs in mouse embryos. Our analysis shows a progressive decline in wavefront ENCC potency during migration and identifies transcription factors governing their specification and differentiation. We further delineate key signaling pathways (ephrin-Eph, Wnt-Frizzled, and Sema3a-Nrp1) utilized by wavefront ENCCs to interact with their surrounding cells. Disruptions in these pathways are observed in human Hirschsprung's disease gut tissue, linking them to ENS malformations. Additionally, we observed region-specific and cell-type-specific transcriptional changes in surrounding gut tissues upon wavefront ENCC arrival, suggesting their role in shaping the gut microenvironment. This work offers a roadmap of ENS development, with implications for understanding ENS disorders.

Abstract
Hirschsprung disease (HSCR) is a rare congenital intestinal disease that occurs in 1 in 5,000 live births. HSCR is characterized by the absence of ganglion cells in the myenteric and submucosal plexuses of the intestine. Most patients present during the neonatal period with the first meconium passage delayed beyond 24 h, abdominal distension and vomiting. Syndromes associated with HSCR include trisomy 21, Mowat-Wilson syndrome, congenital central hypoventilation syndrome, Shah-Waardenburg syndrome and cartilage-hair hypoplasia. Multiple putative genes are involved in familial and isolated HSCR, of which the most common are the RET proto-oncogene and EDNRB. Diagnosis consists of visualization of a transition zone on contrast enema and confirmation via rectal biopsy. HSCR is typically managed by surgical removal of the aganglionic bowel and reconstruction of the intestinal tract by connecting the normally innervated bowel down to the anus while preserving normal sphincter function. Several procedures, namely Swenson, Soave and Duhamel procedures, can be undertaken and may include a laparoscopically assisted approach. Short-term and long-term comorbidities include persistent obstructive symptoms, enterocolitis and soiling. Continued research and innovation to better understand disease mechanisms holds promise for developing novel techniques for diagnosis and therapy, and improving outcomes in patients.

Life Sci 2021; 278:119577. [PMID: 33961858 DOI: 10.1016/j.lfs.2021.119577] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 04/23/2021] [Accepted: 04/29/2021] [Indexed: 12/11/2022]
Abstract
OBJECTIVES This study aims to investigate the role of demethylase ALKBH5 mediated demethylation of TAGLN mRNA in the occurrence of Hirschsprung's disease (HSCR), and to clarify how ALKBH5 reduces the m6A level of TAGLN mRNA and inhibits its degradation, thereby inhibiting the proliferation and migration of neural crest cells, and potentially contributing to the occurrence of HSCR. MATERIAL AND METHODS Quantitative real-time PCR (qRT-PCR) and Western-Blot (WB) were conducted to test the expression level of ALKBH5 and TAGLN genes. Cell function assays were adopted to detect cell phenotypes. The qRT-PCR and methylated RNA immunoprecipitation (MeRIP-qPCR) were used to test the regulation of TAGLN by ALKBH5. RESULTS 1. Compared with control intestinal tissue, the expression level of TAGLN and ALKBH5 in the aganglionic intestinal tissue of HSCR is increased. 2. The MeRIP-PCR and dualluciferase report confirmed that ALKBH5 could bind to m6A sites of TAGLN mRNA and reduce the m6A level of TAGLN mRNA. 3. In vitro cell experiments confirmed that overexpression of ALKBH5 can inhibit the degradation of TAGLN mRNA, increase the expression of TAGLN, thereby inhibiting cell proliferation and migration. 4. A zebrafish model of ALKBH5 overexpression was constructed. Studies have shown that ALKBH5 could inhibit the proliferation and migration of zebrafish enteric neurons. CONCLUSIONS ALKBH5 could demethylate TAGLN mRNA and up-regulate TAGLN expression, leading to the inhibition of proliferation and migration of enteric neural crest cells and contributing to the occurrence of HSCR.
