PURPOSE OF REVIEW: Cardiometabolic diseases increasingly afflict our aging, dysmetabolic population. Complex signals regulating low-density lipoprotein receptor-related protein (LRP) and frizzled protein family members - the plasma membrane receptors for the cadre of Wnt polypeptide morphogens - contribute to the control of cardiovascular homeostasis. RECENT FINDINGS: Both canonical (β-catenin-dependent) and noncanonical (β-catenin-independent) Wnt signaling programs control vascular smooth muscle (VSM) cell phenotypic modulation in cardiometabolic disease...

Bone loss is a serious clinical issue in patients with cerebral palsy (CP). Sclerostin has garnered interest as a key mechanosensor in osteocytes, leading to considerations of the therapeutic utilization of anti-sclerostin medications. This study was undertaken to determine associations among mechanical unloading, sclerostin levels, and bone imbalance in patients with CP. A total of 28 patients with CP participated in this cross-sectional study. The following measurements were taken: anthropometrics, clinical diagnosis of CP subtype and ambulatory status, bone mineral density (BMD) z-scores at the lumbar spine and hip, and blood biochemical markers, including sclerostin, parathyroid hormone (PTH), osteocalcin, C-terminal telopeptide, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, creatinine, calcium, and phosphorus...

BACKGROUND: Observational studies have shown a beneficial effect of obesity on bone health; however, most of those studies were not based on bone biopsies. Metabolic syndrome (MetS) could have an effect on bone remodeling. However, there are no data on the effects of MetS in the presence of renal osteodystrophy. OBJECTIVE: The aim of this study was to investigate associations between MetS and renal osteodystrophy using the bone histomorphometric turnover-mineralization-volume (TMV) classification...

The present study extends our previous findings that exercise, which prevents the onset of insulin resistance and type 2 diabetes (T2D), also prevents the detrimental effects of T2D on whole-bone and tissue-level strength. Our objective was to determine whether exercise improves bone's structural and material properties if insulin resistance is already present in the Otsuka Long-Evans Tokushima Fatty (OLETF) rat. The OLETF rat is hyperphagic due to a loss-of-function mutation in cholecystokinin-1 receptor (CCK-1 receptor), which leads to progressive obesity, insulin resistance and T2D after the majority of skeletal growth is complete...

Bone loss is the result of a negative unbalance between bone formation ad bone resorption. In the last years, the studies on the Wnt canonical pathway have highlighted its crucial role in bone balance through its influence on the activity and maturation of the osteoblast line and in the Receptor Activator of Nuclear Factor κ B (RANK) - RANK ligand (RANKL)/Osteoprotegerin (OPG) system. These mechanisms are involved not only in the pathological processes inducing not only systemic bone loss (ie. Postmenopausal osteoporosis, glucocorticoid-induced osteoporosis, etc...

During development and homeostasis, precise control of Wnt/β-catenin signaling is in part achieved by secreted and membrane proteins that negatively control activity of Wnt co-receptors, Lrp5 and Lrp6. Lrp4 is related to Lrp5/6 and is implicated in modulation of Wnt/β-catenin signaling presumably through its ability to bind to the Wise (Sostdc1)/Sost (Sclerostin) family of Wnt antagonists. To gain insights into the molecular mechanisms of Lrp4 function in modulating Wnt signaling, we performed an array of genetic analyses in murine tooth development, where Lrp4 and Wise play important roles...

BACKGROUND: Romosozumab is a monoclonal antibody that inhibits sclerostin and rapidly increases bone mineral density (BMD) through a dual effect on bone by increasing bone formation and decreasing bone resorption, as shown in a global phase 2 study in postmenopausal women with low bone mass. Here, we report the key results of a phase 2, double-blind, placebo-controlled, dose-ranging study to assess the efficacy and safety of romosozumab in postmenopausal Japanese women with osteoporosis...

Sclerostin inhibits Wnt/β-catenin signaling pathway, thereby decreasing bone formation. Osteoblast stimulating actions of parathyroid hormone (PTH) are mediated by suppression of sclerostin. Thus, sclerostin may reflect both bone metabolism and parathyroid function. The study was aimed to analyze the patterns of the changes of mineral and bone biomarkers for 9 months following kidney transplantation (KTx). Thirty-five patients after KTx were included into a 9-month observational study. Serum creatinine, calcium, phosphorus, 25-OH vitamin D, PTH, fibroblast growth factor 23 (FGF-23), sclerostin, and bone-specific alkaline phosphatase (BAP) were measured before KTx, and 1, 2 weeks, and 1, 2, 3, 4, 5, 6, and 9 months thereafter...

Sclerostin is a known inhibitor of the Wnt signaling pathway which is involved in osteogenesis and, when inactivated, stimulates bone formation. To our knowledge, this effect has not been studied in the context of distraction osteogenesis (DO). Tibial DO was conducted on a total of 24 wild-type mice, which were then divided into 2 groups-a saline injection group (control) and an anti-sclerostin (Scl-Ab) injection group (treatment). The mice in the treatment group received 100 mg/kg intravenous injections of the antibody weekly until killing...

Psoriatic Arthritis (PsA) is characterized by bone erosive damage often associated with exuberant bone formation especially in enthesial sites. Dkk-1 and sclerostin are the main inhibitors of the WNT/β-catenin signaling pathway and play a key role in the regulation of both bone formation and resorption. We performed this study in order to compare the serum levels of the WNT-pathway regulators along with bone turnover markers (BTM) and parathyroid hormone (PTH) between three different groups: one group of female patients affected by PsA, one group of female patients affected by rheumatoid arthritis (RA), and healthy female controls (HC)...

OBJECTIVE: We have previously demonstrated that LIPUS stimulates endochondral ossification with decreased expression of sclerostin. The Wnt signaling pathway was examined in vitro to further address the effect of LIPUS on endochondral ossification. MATERIALS AND METHODS: ATDC5 cells were plated at an initial density of 6 × 10 cells/well in a 6-multiwell plate and cultured in the presence of 5% FBS plus ITS. The bottom of the culture plate was treated every day with LIPUS for 20 minutes...

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...

Osteogenesis imperfecta (OI) is the most common inherited form of bone fragility and includes a heterogenous group of genetic disorders which most commonly result from defects associated with type 1 collagen. 85%-90% of cases are inherited in an autosomal dominant manner and are caused by mutations in the COL1A1 and COL1A2 genes, leading to quantitative or qualitative defects in type 1 collagen. In the last decade, defects in several other proteins involved in the normal processing of type 1 collagen have been described...

BACKGROUND: Sclerostin is an inhibitor of the wingless-type mouse mammary tumor virus integration site family/β-catenin signalling pathway (WβcSP), which plays an important role in bone metabolism and in vascular biology. It could act protective regarding atherosclerosis development through its effect on WβcSP in vascular cells. Nevertheless, results of studies analyzing association between circulating sclerostin level (CSL) and atherosclerotic diseases (AD) are showing conflicting results...

Osteoporosis induction in a sheep model by steroid administration combined with ovariectomy recapitulates decreased bone formation and substandard matrix mineralization in patients. Recently, the role of osteocytes has been frequently addressed, with focus on their role in osteoclastogenesis. However, the quantification of receptor activator of NF-κB ligand (RANKL) and osteoprotegerin (OPG) signaling in osteocytes was not studied in sheep. The current study reproduced the sheep model of osteoporosis to study the RANKL/OPG ratio correlation to the method of osteoporosis induction...

PURPOSE OF REVIEW: Over the past decades, osteocytes have emerged as mechano-sensors of bone and master regulators of bone homeostasis. This article summarizes latest research and progress made in understanding osteocyte mechanobiology and critically reviews tools currently available to study these cells. RECENT FINDINGS: Whereas increased mechanical forces promote bone formation, decrease loading is always associated with bone loss and skeletal fragility. Recent studies identified cilia, integrins, calcium channels, and G-protein coupled receptors as important sensors of mechanical forces and Ca(2+) and cAMP signaling as key effectors...

Bone morphogenetic proteins (Bmp) are well-known to induce bone formation following chondrogenesis, but the direct role of Bmp signaling in the osteoblast lineage is not completely understood. We have recently shown that deletion of the receptor Bmpr1a in the osteoblast lineage with Dmp1-Cre reduces osteoblast activity in general but stimulates proliferation of preosteoblasts specifically in the cancellous bone region, resulting in diminished periosteal bone growth juxtaposed with excessive cancellous bone formation...
