The achievement of more accurate diagnosis would greatly benefit the management of patients with osteogenesis imperfecta (OI). In this study, we present the largest OI sample in China as screened by next generation sequencing. In particular, we successfully identified 81 variants, which included 45 novel variants. We further did a genotype-phenotype analysis, which helps make a better understanding of OI. INTRODUCTION: This study aims to reveal the gene mutation spectrum and the genotype-phenotype relationship among Chinese OI patients by next generation sequencing (NGS)...

The midbrain-hindbrain boundary (MHB) acts as an organizer and controls the fate of neighboring cells to develop into either mesencephalic (midbrain) or metencephalic (hindbrain) cells by secreting signaling molecules like Wnt1 and Fgf8. The zebrafish is an excellent vertebrate model for studying MHB development due to the ease of gene manipulation and the possibility of following cellular dynamics and morphogenetic processes using live imaging. Currently, only very few reporter and/or Cre-driver lines are available to study gene expression at the MHB, hampering the understanding of MHB development, and traditional transgenic technologies using promoter/enhancer fragments or bacterial artificial chromosome (BAC)-mediated transgenesis often do not faithfully recapitulate endogenous expression patterns...

WNT1-inducible signaling pathway protein-1 (WISP-1) is an extracellular matrix-related protein that plays multiple roles in cellular physiology and pathology. Accumulating evidence shows that WISP-1 is involved in the process underlying fibrotic diseases. However, the correlation between WISP-1 and renal fibrosis is unknown. In this study, we hypothesized that WISP-1 levels might be correlated with renal fibrosis and could be used as a noninvasive biomarker to screen for renal fibrosis in patients with chronic kidney disease (CKD)...

BACKGROUND: Osteogenesis Imperfecta (OI) is a heritable bone fragility disorder usually caused by dominant variants in COL1A1 or COL1A2 genes. Over the last few years, seventeen genes including twelve autosomal recessive and five autosomal dominant forms of OI, involved in various aspects of bone formation, have been identified. METHODS: Whole exome sequencing followed by conventional Sanger sequencing was performed in single affected individual IV-3 in the present family...

OBJECTIVE: Smooth muscle cells (SMCs) of the proximal thoracic aorta are embryonically derived from the second heart field (SHF) and cardiac neural crest (CNC). However, distributions of these embryonic origins are not fully defined. The regional distribution of SMCs of different origins is speculated to cause region-specific aortopathies. Therefore, the aim of this study was to determine the distribution of SMCs of SHF and CNC origins in the proximal thoracic aorta. APPROACH AND RESULTS: Mice with repressed LacZ in the ROSA26 locus were bred to those expressing Cre controlled by either the Wnt1 or Mef2c (myocyte-specific enhancer factor 2c) promoter to trace CNC- and SHF-derived SMCs, respectively...

Large epidemiological studies clearly demonstrate that multiple episodes of acute kidney injury contribute to the development and progression of kidney fibrosis. Although our understanding of kidney fibrosis has improved in the past two decades, we have limited therapeutic strategies to halt its progression. Myofibroblast differentiation and proliferation remain critical to the progression of kidney fibrosis. Although canonical Wnt signaling can trigger the activation of myofibroblasts in the kidney, mediators of Wnt inhibition in the resident progenitor cells are unclear...

PURPOSE OF REVIEW: This review summarizes our current knowledge on primary osteoporosis in children with focus on recent genetic findings. RECENT FINDINGS: Advances in genetic research, particularly next-generation sequencing, have found several genetic loci that associate with monogenic forms of inherited osteoporosis, widening the scope of primary osteoporosis beyond classical osteogenesis imperfecta. New forms of primary osteoporosis, such as those related to WNT1, PLS3, and XYLT2, have identified defects outside the extracellular matrix components and collagen-related pathways, in intracellular cascades directly affecting bone cell function...

Here we investigate the role of epigenetic factors in controlling the timing of cranial neural crest cell differentiation. The gene coding for histone H3 lysine 9 methyltransferase G9A was conditionally deleted in neural crest cells with Wnt1-Cre. The majority of homozygous-null animals survived to birth but thereafter failed to thrive. Phenotypic analysis of postnatal animals revealed that the mutants displayed incomplete ossification and 20% shorter jaws as compared to their wild-type littermates. At E13...

Glioma is the most common primary brain tumor in adults. Six3 is a human homologue of the highly conserved sine oculis gene family and essential transcription regulatory factor in process of eye and fetal forebrain development. However, little is known about the role of Six3 in human tumorigenesis. The aim of this study is to investigate the methylation/expression of Six3 and reveal its function and action mechanism in glioma. Our results showed that Six3 was down-regulated in human glioma tissues and human glioma SHG-44, U251, SF126 and U373-MG cells compared with the normal tissues...

Guarana (Paullinia cupana) is a plant originated in Brazil that presents a beneficial effect on body weight control and metabolic alterations. The aim of this study was to evaluate the effects of guarana on genes and miRNAs related to adipogenesis in 3T3L1 cells. The anti-adipogenic effect of guarana was evaluated by Oil Red-O staining. Gene and miRNA expression levels were determined by real time PCR. The Cebpα and β-catenin nuclear translocation were evaluated using immunocytochemistry. Our data indicated that the triglyceride-reducing effect of guarana was dose-dependent from 100 to 300 µg/mL (-12%, -20%, -24% and -40%, respectively, p < 0...

WNT proteins drive the development and maintenance of many tissues, including bone. It is less clear which of the many WNT proteins act on bone or where these WNTs act in the skeleton; however, loss-of-function mutations in WNT1 cause bone fragility in children and adults. In this issue of the JCI, Joeng and colleagues demonstrate that bone formation is under the control of WNT1 produced by osteocytes, the cells that reside deep in the bone matrix and form dendritic networks. The implication of WNT1 in the control of bone formation identifies a potential new target for the treatment of low bone mass disorders, such as osteoporosis...

Mutations in WNT1 cause osteogenesis imperfecta (OI) and early-onset osteoporosis, identifying it as a key Wnt ligand in human bone homeostasis. However, how and where WNT1 acts in bone are unclear. To address this mechanism, we generated late-osteoblast-specific and osteocyte-specific WNT1 loss- and gain-of-function mouse models. Deletion of Wnt1 in osteocytes resulted in low bone mass with spontaneous fractures similar to that observed in OI patients. Conversely, Wnt1 overexpression from osteocytes stimulated bone formation by increasing osteoblast number and activity, which was due in part to activation of mTORC1 signaling...

Electroacupuncture (EA) has been demonstrated to promote the functional recovery of neurons following spinal cord injury (SCI); however, the mechanisms underlying its effects have yet to be elucidated. The Wnt/β-catenin signaling pathway has been implicated in the regulation of the balance between growth, proliferation and differentiation of neural precursor cells. The present study aimed to investigate the effects of EA therapy on Wnt/β‑catenin‑regulated gene expression and neuronal recovery in rats with SCI...

Adequate placental angiogenesis is critical for the establishment of the placental circulation and thus for normal feto-placental growth and development. Fatty acid-binding protein-4 (FABP4) plays a pro-angiogenic role in endothelial cells; however, very little information is available in placental first trimester trophoblast cells. Here we report that exogenously added FABP4 (exo-FABP4) stimulated tube formation (as a measure of in vitro angiogenesis) in HTR8/SVneo trophoblastic cells. HTR-8/SVneo cells were incubated in the presence of exogenously added FABP4 at different concentrations and time points...

Cyclin-dependent kinase 5 (Cdk5) is recognized as a unique member among other Cdks due to its versatile roles in many biochemical processes in the nervous system. The proper development of neuronal dendrites is required for the formation of complex neural networks providing the physiological basis of various neuronal functions. We previously reported that sparse dendrites were observed on cultured Cdk5-null Purkinje cells and Purkinje cells in Wnt1(cre) -mediated Cdk5 conditional knockout (KO) mice. In the present study, we generated L7(cre) -mediated p35; p39 double KO (L7(cre) -p35(f/f) ; p39(-/-) ) mice whose Cdk5 activity was eliminated specifically in Purkinje cells of the developing cerebellum...
