Indian Hedgehog Signaling in the Postnatal Growth Plate

ABSTRACT: In order to characterize mRNA expression in the growth plate, we microdissected postnatal rat growth plates into their constituent zones and used microarray analysis to assess the abundences of individual transcripts. Expression patterns of PTHrP and Ihh-related genes were confirmed using real-time PCR. Using a gli1-lacZ mouse, Gli1 expression, presumably representing Ihh signaling, was visualized during pre- and postnatal development.

Microdissection was used to collect individual growth plate zones from proximal tibiae of 1-wk rats and gene expression was analyzed using microarray.

The G Protein-Coupled Receptor ADGRG6 Maintains Mouse Growth Plate Homeostasis by Negatively Regulating IHH Signaling

Project description:ADGRG6 is a cartilage-enriched G protein-coupled receptor (GPCR). Using molecular mouse genetics and spatial transcriptomics approaches, we demonstrated that Adgrg6 has a vital role in regulating chondrocyte differentiation and growth plate homeostasis by positively regulating the formation and/or maintenance of the PTHrP (+) cell population and negatively regulating the IHH signaling in postnatal growth plates.

The function of morphogen Indian Hedgehog in the colon

Project description:The morphogen Indian Hedgehog plays a very important role during intestinal embryogenesis, but also maintains homeostasis of the adult gut. Intestinal Indian Hedgehog is expressed by the intestinal epithelium and signals in paracrine manner to fibroblasts in the stromal compartment. Unresolved deletion of Ihh from the intestinal epithelium leads to a severe enterocolitis. We studied the short term changes in the colon upon deletion of Ihh from the epithelial layer.

Gene expression profiling of conditional ablation of Indian hedgehog in the mouse uterus

Project description:Conditional ablation of Indian hedgehog (Ihh) in the murine uterus results in mice that are sterile due to defects in embryo implantation. We performed microarray analysis on these mice at the time point at which the Ihh target genes are induced by the administration of exogenous hormone to mimic day 3.5 of pregnancy. This analysis identified 863 genes altered by the conditional ablation of Ihh. Of these, genes that regulated the cell cycle were overrepresented. In addition, genes involved in epidermal growth factor (EGF) and estrogen (E2) signaling were found to be deregulated upon Ihh ablation. Furthermore, upon conditional ablation of Ihh, 15 month old mice exhibited hallmarks of estrogenized uteri such as cystically dilated glands and hyalinized stroma. Thus, Ihh regulates embryo implantation by impacting the cell cycle, EGF signaling, and E2 signaling. Keywords: two group comparison

A multipartite enhancer ensemble coordinates pleiotropic developmental functions of Indian hedgehog

Project description:Copy number variations (CNVs) including enhancers frequently appear associated with disease, induced by pathomechanisms that are poorly understood. Here we show through transgenic reporter and genome editing studies in mice that Indian hedgehog (Ihh) is regulated by a constellation of enhancers of unusual complexity and we uncover how duplications within this enhancer architecture cause phenotypes reminiscent of those observed in human patients. At least nine enhancers with distinct combinations of activities orchestrate the expression of Ihh in the digit anlagen, growth plates, skull sutures, and digit tips. Consecutive deletions show that they function in an additive manner resulting in growth defects. Duplications, in contrast, cause not only dose-dependent upregulation of Ihh, but also misexpression, leading to phenotypes influenced by the copy number and relative positioning of individual elements. Taken together, our results uncover a complex regulatory landscape at the Ihh locus and exemplify the intricate and precise control of gene expression during morphogenetic processes.

Cyclic tensile strain enhances the expression of Indian hedgehog and progression of ossification of the human cervical posterior longitudinal ligament

Project description:The initiation and/or progression of ossification of the posterior longitudinal ligament (OPLL) is associated with cyclic tensile strain, but the pathomechanism of OPLL remains unclear. Indian hedgehog (Ihh) and its related signaling are key factors in normal enchondral ossification. However, the relation of OPLL to Ihh is unclear. The purpose of this study is to investigate the contribution of mechanical strain to OPLL and the relation of Ihh to OPLL.
