Research progress on the etiology and pathogenesis of adolescent idiopathic scoliosis.

Research progress on the etiology and pathogenesis of adolescent idiopathic scoliosis. Chin Med J (Engl). 2020 Jan 16;: Authors: Peng Y, Wang SR, Qiu GX, Zhang JG, Zhuang QY Abstract Etiology of adolescent idiopathic scoliosis (AIS), a complicated three-dimensional spinal deformity with early-onset, receives continuous attention but remains unclear. To gain an insight into AIS pathogenesis, this review searched PubMed database up to June 2019, using key words or medical subject headings terms including "adolescent idiopathic scoliosis," "scoliosis," "pathogenesis," "etiology," "genetics," "mesenchymal stem cells," and their combinations, summarized existing literatures and categorized the theories or hypothesis into nine aspects. These aspects include bone marrow mesenchymal stem cell studies, genetic studies, tissue analysis, spine biomechanics measurements, neurologic analysis, hormone studies, biochemical analysis, environmental factor analysis, and lifestyle explorations. These categories could be a guidance for further etiology or treatment researches to gain inspiration. PMID: 31972723 [PubMed - as supplied by publisher]

Coexistence of abnormal skeletal growth and reduced bone mineral density in the context of adolescent idiopathic scoliosis (AIS) suggests disturbed bone metabolism existing in such patients. Our previous study suggested increased proliferation ability and decreased osteogenic differentiation ability of Bone marrow mesenchymal stem cells (BM-MSCs) of AIS.

ConclusionOur findings indicated that GPR126-NTFs play a role in skeletal development, and the inclusion/exclusion of exon6 may regulate the bone formation-related functions of GPR126. The convex/concave asymmetric expression of GPR126-exon6in may be an important factor in abnormal bone formation of AIS.Graphical abstractThese slides can be retrieved under Electronic Supplementary Material.

Contributors : Jianguo Zhang ; Qianyu Zhuang ; Guixing QiuSeries Type : Expression profiling by arrayOrganism : Homo sapiensAbnormal osteogenic differentiation of mesenchymal stem cells (MSCs) is implicated in the pathogenesis of Adolescent idiopathic scoliosis(AIS). However, the biological roles of long noncoding RNAs (lncRNAs) in the regulation of osteogenic differentiation of MSCs are unknown.We used LncRNA microarray analyses of bone marrow (BM) MSCs from non-AIS patients and AIS patients and identified significant differentially expressed lncRNAs in AIS BM-MSCs.

Abstract To investigate the role of mTOR signaling pathway in bone marrow mesenchymal stem cells (BMSCs) differentiation into osteoblast in degenerative scoliosis (DS). The rat model of DS was established. Thirty-two Sprague-Dawley (SD) rats were selected and divided into the normal control group, the positive control group (normal rats injected with rapamycin), the negative control group (DS rats injected with PBS) and the experiment group (DS rats injected with rapamycin). H&E staining was performed to observe the osteogenesis of scoliosis. The BMSCs were obtained and assigned into seven groups: the normal contr...

li PY Abstract Osteogenesis imperfecta is an inherited connective tissue disorder with wide phenotypic and molecular heterogeneity. A common issue associated with the molecular abnormality is a disturbance in bone matrix synthesis and homeostasis inducing bone fragility. In very early life, this can lead to multiple fractures and progressive bone deformities, including long bone bowing and scoliosis. Multidisciplinary management improves quality of life for patients with osteogenesis imperfecta. It consists of physical therapy, medical treatment and orthopaedic surgery as necessary. Medical treatment consists of b...

Authors: Chen C, Xu C, Zhou T, Gao B, Zhou H, Chen C, Zhang C, Huang D, Su P Abstract Abnormalities of membranous and endochondral ossification in patients with adolescent idiopathic scoliosis (AIS) remain incompletely understood. To investigate abnormalities in the melatonin signaling pathway and cellular response to melatonin in AIS, a case‑control study of osteogenic and chondrogenic differentiation was performed using human mesenchymal stem cells (hMSCs). AIS was diagnosed by physical and radiographic examination. hMSCs were isolated from the bone marrow of patients with AIS and control subjects (n=12 each), ...
