TALPID3/KIAA0586 Regulates Multiple Aspects of Neuromuscular Patterning During Gastrointestinal Development in Animal Models and Human. Front Mol Neurosci 2022; 14:757646. [PMID: 35002618 PMCID: PMC8733242 DOI: 10.3389/fnmol.2021.757646] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Accepted: 11/10/2021] [Indexed: 12/26/2022] Open
Abstract
TALPID3/KIAA0586 is an evolutionary conserved protein, which plays an essential role in protein trafficking. Its role during gastrointestinal (GI) and enteric nervous system (ENS) development has not been studied previously. Here, we analyzed chicken, mouse and human embryonic GI tissues with TALPID3 mutations. The GI tract of TALPID3 chicken embryos was shortened and malformed. Histologically, the gut smooth muscle was mispatterned and enteric neural crest cells were scattered throughout the gut wall. Analysis of the Hedgehog pathway and gut extracellular matrix provided causative reasons for these defects. Interestingly, chicken intra-species grafting experiments and a conditional knockout mouse model showed that ENS formation did not require TALPID3, but was dependent on correct environmental cues. Surprisingly, the lack of TALPID3 in enteric neural crest cells (ENCC) affected smooth muscle and epithelial development in a non-cell-autonomous manner. Analysis of human gut fetal tissues with a KIAA0586 mutation showed strikingly similar findings compared to the animal models demonstrating conservation of TALPID3 and its necessary role in human GI tract development and patterning.

Abstract
BACKGROUND Postoperative incontinence and constipation still remain the major complications of anorectal malformations (ARMs), despite improvements in their treatment. One of the most important factors that affect postoperative anorectal function is malformations in the lumbosacral spinal cord. However, far too little attention has been paid to the underlying mechanism that produces these malformations. MATERIALS AND METHODS The levels of sonic hedgehog (Shh), patched homolog 1 (Ptch1), and zinc finger-containing transcription factors 1 (Gli1) expression were investigated in the lumbosacral spinal cord in ethylenethiourea-exposed rat fetus with ARMs, and Shh, Ptch1, and Gli1 expression was confirmed with immunohistochemical staining, quantitative real-time polymerase chain reaction, and western blot analyses during lumbosacral spinal cord development both in the ARMs and normal rat embryos. RESULTS Our results have shown that Shh, Ptch1, and Gli1 expression in the lumbosacral spinal cord of rat embryos with ARMs was decreased at both the messenger RNA and protein levels, when compared with their expression levels in normal tissues (P < 0.05). CONCLUSIONS This study demonstrated that the expression of Shh, Ptch1, and Gli1 in lumbosacral spinal cord was remarkably reduced during late developmental stages in fetal rats with ARMs. These findings offered some important insights into the involvement of the Shh-Ptch1-Gli1 signaling pathway in the pathogenesis of lumbosacral spinal cord maldevelopment in rat fetus with ARMs, which leads to complications after procedures for ARMs.

Abstract
Aim The aim of the study was to investigate the signal transduction mechanism of Hedgehog–vascular endothelial growth factor in oxygen-induced retinopathy (OIR) and the effects of cyclopamine on OIR. Methods An OIR model was established in C57BL/6J mice exposed to hyperoxia. Two hundred mice were randomly divided into a control group, an OIR group, an OIR-control group (treated with isometric phosphate-buffered saline by intravitreal injection), and a cyclopamine group (treated with cyclopamine by intravitreal injection), with 50 mice in each group. The retinal vascular morphology was observed using adenosine diphosphatase and number counting using hematoxylin and eosin-stained image. Quantitative real-time quantitative polymerase chain reaction was used to detect mRNA expression. Protein location and expression were evaluated using immunohistochemistry and Western blot. Results The OIR group and OIR-control group demonstrated large-area pathological neovascularization and nonperfused area when compared with the control group (both P<0.05). The area of nonperfusion and neovascularization in the cyclopamine group was significantly reduced compared with the OIR and OIR-control groups (both P<0.05). Compared with the control group, the OIR and OIR-control groups had more vascular endothelial cells breaking through the inner limiting membrane. The number of new blood vessel endothelial cell nuclei in the cyclopamine group was significantly reduced (both P<0.05) when compared with the OIR and OIR-control groups. The mRNA and protein expressions of Smoothened, Gli1, and vascular endothelial growth factor in the signal pathway of the OIR and OIR-control groups were significantly higher than those of the control group; however, in the cyclopamine group, these factors were reduced when compared with the OIR and OIR-control groups (all P<0.05). Conclusion Our data suggest that abnormal expression of the Hedgehog signaling pathway may be closely associated with the formation of OIR. Inhibiting the Smoothened receptor using cyclopamine could control retinal neovascularization, providing new ideas and measures for the prevention of oxygen-induced retinal neovascularization.
