Abstract
AIMS Temporomandibular disorder can cause degenerative pathological changes by aseptic inflammation in the temporomandibular joint (TMJ). Vitamin D (VD) is known for maintaining calcium homeostasis, and recent studies indicated that VD and the vitamin D receptor (VDR) are important in inflammatory responses. In this study, we explored the anti-inflammatory effect of VD-VDR signaling axis in TMJ pathological degeneration. MAIN METHODS Mice ablated for Vdr (Vdr-/-res) were fed with a rescue diet to avoid hypocalcemia. With abnormal mechanical stimulation, unilateral anterior crossbite (UAC) induced temporomandibular disorders in mice. Histological staining, immunohistochemistry staining, and micro-CT analysis were performed to evaluate TMJ pathological changes. To identify the mechanisms in the aseptic inflammatory process, in vitro experiments were conducted on wild-type (WT) and Vdr-/- chondrocytes with compressive mechanical stress loading, and the related inflammatory markers were examined. KEY FINDINGS Vdr-/-res mice did not develop rickets with a high calcium rescue diet. The TMJ cartilage thickness in Vdr-/-res mice was significantly decreased with mechanical stress stimulation compared to WT mice. UAC-induced bone resorption was obvious, and the number of osteoclasts significantly increased in Vdr-/-res mice. The proliferation was inhibited and the gene expression of Il1b, Mmp3, and Mmp13 was significantly increased in Vdr-/- chondrocytes. However, WT chondrocytes showed significantly increased Tnfa gene expression as a response to mechanical stress but not in Vdr-/- chondrocytes. SIGNIFICANCE VD-VDR is crucial in TMJ pathological changes under abnormal mechanical stimulation. Deletion of Vdr exacerbated inflammatory response excluding TNFα, inhibited chondrocyte proliferation, and promoted bone resorption in TMJ.

Abstract
Growth plate chondrocytes are regulated by numerous factors and hormones as they mature during endochondral bone formation, including transforming growth factor beta-1 (TGFb1), bone morphogenetic protein 2 (BMP2), insulin-like growth factor-1 (IFG1), parathyroid hormone and parathyroid hormone related peptide (PTH, PTHrP), and Indian hedgehog (IHH). Chondrocytes in the growth plate's growth zone (GC) produce and export matrix vesicles (MVs) under the regulation of 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3]. 1α,25(OH)2D3 regulates MV enzyme composition genomically and 1α,25(OH)2D3 secreted by the cells acts on the MV membrane nongenomically, destabilizing it and releasing MV enzymes. This study examined the regulatory role 1α,25(OH)2D3 has over production and packaging of microRNA (miRNA) into MVs by GC cells and the release of miRNA by direct action on MVs. Costochondral cartilage GC cells were treated with 1α,25(OH)2D3 and the miRNA in the cells and MVs sequenced. We also treated MVs with 1α,25(OH)2D3 and determined if the miRNA was released. To assess whether MVs can act directly with chondrocytes and if this is regulated by 1α,25(OH)2D3, we stained MVs with a membrane dye and treated GC cells with them. 1α,25(OH)2D3 regulated production and packaging of a unique population of miRNA into MVs compared to the vehicle control population. 1α,25(OH)2D3 treatment of MVs did not release miRNA. Stained MVs were endocytosed by GC cells and this was increased with 1α,25(OH)2D3 treatment. This study adds new regulatory roles for 1α,25(OH)2D3 with respect to packaging and transport of MV miRNAs.

Vitamin D Receptor Gene Polymorphisms and Risk of Knee Osteoarthritis: Possible Correlations with TNF-α, Macrophage Migration Inhibitory Factor, and 25-Hydroxycholecalciferol Status. Biochem Genet 2021; 60:611-628. [PMID: 34370118 DOI: 10.1007/s10528-021-10116-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Accepted: 08/02/2021] [Indexed: 11/09/2022]
Abstract
Osteoarthritis (OA) etiology and pathogenesis not yet fully understood. We studied the role of vitamin D receptor single-nucleotide polymorphisms (VDR-SNPs), vitamin D3, serum and synovial macrophage migration inhibitory factor (MIF), and tumor necrosis factor-α (TNF-α) in the development and progression of knee OA (KOA). This study included 205 Egyptian subjects (105 patients with KOA and 100 unrelated, healthy matched subjects selected as controls). The patient group was divided into three groups according to KOA severity (mild, moderate, and severe), with 35 patients in each group. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used for the ApaI and TaqI SNPs. Vitamin D, serum and synovial TNF-α, and MIF assays were performed using ELISA kits. There were significantly lower serum levels of 25-hydroxycholecalciferol with significant increasing TNF-α and MIF levels in relation to disease severity among the cases (all: p˂0.05).Wild homozygous and heterozygous mutant genotypes (GG+GT) and G allele of ApaI demonstrated risk for KOA development, with odds ratio OR = 6.313 (95% confidence interval (CI) 2.074-19.210) and OR = 1.532 (95%CI 1.013-2.317), respectively. Homozygous mutant CC genotype and C allele of TaqI could be considered a risk factor associated with KOA development, with OR = 2.667 (95%CI 1.270-5.601) and OR = 0.737 (95%CI 0.496-1.095), respectively. VDR-SNPs, vitamin D3, TNF-α, and MIF could play an essential role in the pathogenesis and progression of KOA with mechanistic associations.

Abstract
The purpose of this study is to evaluate anti-inflammatory and chondro-protective effects of 1,25(OH)2D3 in human chondrocytes and SW1353 cells via investigating expressions of MMPs, TIMPs, VDR, and intracellular signalling pathway mediators such as TLR-2 and -4. The HC and SW1353 cells were treated with 1,25(OH)2D3 at 10, 100, and 1000 nM concentrations in the absence/presence of TNF-α (20 ng/mL) for 48 h. The mRNA expressions of MMP-1, -2, -3, -9, and -13, TIMP-1 and -2, VDR, TLR-2 and -4 in HC and SW1353 cells were detected by qPCR after treatments. The cytotoxicity and cell proliferation analyses were assessed by LDH and WST-1 assay, respectively. Protein levels of MMPs, TIMPs, and VDR were analysed by immunocytochemistry and ELISA methods. TNF-α markedly increased cytotoxicity for 24, 48, 72 h (p < 0.05) and vitamin D treatment was shown to diminish the cytotoxic effect of TNF-α. Cell proliferations increased by Vitamin D in a dose-dependent manner. mRNA expressions of MMP-1, -2, -3, -9, and -13, TLR-2 and -4 genes decreased with 1,25(OH)2D3 treatment (p < 0.05). VDR, TIMP-1 and -2 levels elevated after TNF-α exposure compared with the control group in HC cells (p < 0.05). Protein expression levels were determined using Western blotting, ELISA and immunocytochemistry. 1,25(OH)2D3 via binding to VDR, reversed the effects of TNF-α by inhibiting TLR-2 and 4. Decreased levels of VDR, TIMP-1 and -2 after TNF-α treatment were elevated by 1,25(OH)2D3 proportional with increasing 1,25(OH)2D3 doses. 1,25(OH)2D3 and TNF-α co-treatment decreased MMP-1, -2, -3, -9, and -13 levels were after TNF-α exposure.

Abstract
BACKGROUND Primary Osteoarthritis (OA) of the knee is a multifactorial disease that has an important genetic component, and several genes have been associated with its development. The vitamin D receptor has a role in skeletal metabolism that suggests a relationship with OA. The aim of this study was to analyze the association of Vitamin D receptor gene (VDR) polymorphisms in Mexican Mestizo patients. METHODS A case-control study was conducted in which 107 cases with primary OA of the knee and 114 controls were included. Cases were patients > 40 years of age with a Body mass index (BMI) of ≤27 and a radiological score for OA of the knee of ≥2. Controls were subjects > 40 years of age with a radiological score of < 2. VDR polymorphisms rs1544410, rs7975232, and rs731236 were analyzed by means of restriction endonucleases, and logistic regression was developed to evaluate risk magnitude. RESULTS A significantly increased risk was found of nearly two-fold for the allele T and TT genotypes of rs731236, independently of other well recognized risk factors. CONCLUSIONS The rs731236 polymorphism is associated with the risk of primary OA of the knee in Mexican Mestizo population.

Abstract
Malnutrition is considered a leading cause of growth attenuation in children. When food is replenished, spontaneous catch-up (CU) growth usually occurs, bringing the child back to its original growth trajectory. However, in some cases, the CU growth is not complete, leading to a permanent growth deficit. This review summarizes our current knowledge regarding the mechanism regulating nutrition and growth, including systemic factors, such as insulin, growth hormone, insulin- like growth factor-1, vitamin D, fibroblast growth factor-21, etc., and local mechanisms, including autophagy, as well as regulators of transcription, protein synthesis, miRNAs and epigenetics. Studying the molecular mechanisms regulating CU growth may lead to the establishment of better nutritional and therapeutic regimens for more effective CU growth in children with malnutrition and growth abnormalities. It will be fascinating to follow this research in the coming years and to translate the knowledge gained to clinical benefit.

Abstract
BACKGROUND Vitamin D receptors have been identified in the spinal cord, nerve roots, dorsal root ganglia and glial cells, and its genetic polymorphism association with the development of lumbar disc degeneration and herniation has been documented. Metabolic effects of active vitamin D metabolites in the nucleus pulposus and annulus fibrosus cells have been studied. Lumbar disc herniation is a process that involves immune and inflammatory cells and processes that are targets for immune regulatory actions of vitamin D as a neurosteroid hormone. In addition to vitamin D's immune modulatory properties, its receptors have been identified in skeletal muscles. It also affects sensory neurons to modulate pain. In this study, we aim to study the role of vitamin D3 in discogenic pain and related sensory deficits. Additionally, we will address how post-treatment 25-hydroxy vitamin D3 level influences pain and sensory deficits severity. The cut-off value for serum 25-hydroxy vitamin D3 that would be efficacious in improving pain and sensory deficits in lumbar disc herniation will also be studied. METHODS/DESIGN We will conduct a randomized, placebo-controlled, double-blind clinical trial. Our study population will include 380 cases with one-level and unilateral lumbar disc herniation with duration of discogenic pain less than 8 weeks. Individuals who do not have any contraindications, will be divided into three groups based on serum 25-hydroxy vitamin D3 level, and each group will be randomized to receive either a single-dose 300,000-IU intramuscular injection of vitamin D3 or placebo. All patients will be under conservative treatment. Pre-treatment and post-treatment assessments will be performed with the McGill Pain Questionnaire and a visual analogue scale. For the 15-day duration of this study, questionnaires will be filled out during telephone interviews every 3 days (a total of five times). The initial and final interviews will be scheduled at our clinic. After 15 days, serum 25-hydroxy vitamin D3 levels will be measured for those who have received vitamin D3 (190 individuals).

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disorder of the lung and whole body caused mainly by tobacco smoking. Patients with advanced COPD are in a state of undernutrition, referred to as pulmonary cachexia; the exercise performance and quality of life (QOL) of these patients are deteriorated, the vital prognosis is unfavorable, and the medico-economic burden posed by poorly nourished COPD patients is high. The mainstays of COPD treatment are pharmacotherapy, mainly with bronchodilators, and non-pharmacotherapeutic approaches such as respiratory rehabilitation and nutrition counseling. Nutritional supplement therapy, consisting primarily of high calorie intake, has been demonstrated to be effective for maintaining and improving the muscle strength and exercise tolerance in poorly nourished COPD patients. The efficacy of intake of various nutrients, besides a high calorie intake, for amelioration of the disease state of COPD has also been reported. The roles of adipokines in the pathophysiology of COPD have begun to receive attention recently, and not only their regulatory effects on appetite and nutritional status, but also their influence on systemic inflammation have been increasingly clarified. We review the papers on COPD and nutrition and discuss the role of nutritional supplement therapy in the treatment of COPD.

Abstract
Severe acute respiratory syndrome (SARS) coronavirus (SARS‐CoV) papain‐like protease (PLpro), a deubiquitinating enzyme, demonstrates inactivation of interferon (IFN) regulatory factor 3 and NF‐κB, reduction of IFN induction, and suppression of type I IFN signaling pathway. This study investigates cytokine expression and proteomic change induced by SARS‐CoV PLpro in human promonocyte cells. PLpro significantly increased TGF‐β1 mRNA expression (greater than fourfold) and protein production (greater than threefold). Proteomic analysis, Western blot, and quantitative real‐time PCR assays indicated PLpro upregulating TGF‐β1‐associated genes: HSP27, protein disulfide isomerase A3 precursor, glial fibrillary acidic protein, vimentin, retinal dehydrogenase 2, and glutathione transferase omega‐1. PLpro‐activated ubiquitin proteasome pathway via upregulation of ubiquitin‐conjugating enzyme E2–25k and proteasome subunit alpha type 5. Proteasome inhibitor MG‐132 significantly reduced expression of TGF‐β1 and vimentin. PLpro upregulated HSP27, linking with activation of p38 MAPK and ERK1/2 signaling. Treatment with SB203580 and U0126 reduced PLpro‐induced expression of TGF‐β1, vimentin, and type I collagen. Results point to SARS‐CoV PLpro triggering TGF‐β1 production via ubiquitin proteasome, p38 MAPK, and ERK1/2‐mediated signaling.

Abstract
Umbilical cord stroma mesenchymal stem cells were differentiated toward chondrocyte-like cells using a new in vitro model that consists of the random formation of spheroids in a medium supplemented with fetal bovine serum on a nonadherent surface. The medium was changed after 2 days to one specific for the induction of chondrocyte differentiation. We assessed this model using reverse transcriptase-polymerase chain reaction, flow cytometry, immunohistochemistry, and secretome analyses. The purpose of this study was to determine which proteins were differentially expressed during chondrogenesis. Differential gel electrophoresis analysis was performed, followed by matrix-assisted laser desorption/ionization mass spectrometry protein identification. A total of 97 spots were modulated during the chondrogenesis process, 54 of these spots were identified as 39 different proteins and 15 were isoforms. Of the 39 different proteins identified 15 were down-regulated, 21 were up-regulated, and 3 were up- and down-regulated during the chondrogenesis process. Using Pathway Studio 7.0 software, our results showed that the major cell functions modulated during chondrogenesis were cellular differentiation, proliferation, and migration. Five proteins involved in cartilage extracellular matrix metabolism found during the differential gel electrophoresis study were confirmed using Western blot. The results indicate that our in vitro chondrogenesis model is an efficient and rapid technique for obtaining cells similar to chondrocytes that express proteins characteristic of the cartilage extracellular matrix. These chondrocyte-like cells could prove useful for future cell therapy treatment of cartilage pathologies.

Lee CSD, Chen J, Wang Y, Williams JK, Ranly DM, Schwartz Z, Boyan BD. Coordinated tether formation in anatomically distinct mice growth centers is dependent on a functional vitamin D receptor and is tightly linked to three-dimensional tissue morphology. Bone 2011; 49:419-27. [PMID: 21601024 DOI: 10.1016/j.bone.2011.05.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2011] [Revised: 04/27/2011] [Accepted: 05/04/2011] [Indexed: 11/17/2022]
Abstract
Bone bridges linking the epiphysis and metaphysis termed "tethers" have been found in the femoral growth plates of C57Bl/6 mice and are disrupted when the vitamin D receptor (VDR) is ablated. It is unknown if tethers are found in other growth centers, if they are regulated in a comparable manner, or if they have a functional role in skeletal development or stability. To address this, distal femoral growth plates (GPs) and spheno-occipital synchondroses (SOSs) of wild-type C57Bl/6 mice from 2 to 15 weeks of age were analyzed using μCT scans. The GPs and SOSs of VDR+/+ and VDR-/- mice fed regular or rescue diets to restore mineral homeostasis until 10 weeks of age were also scanned. Tethers in GPs and SOSs both thickened and accumulated in number as these growth centers decreased in size. Ablating the VDR made GPs and SOSs rachitic and nearly eliminated tether formation. Rescue diets restored the volume of both growth centers but only partially restored growth center thickness and tether formation, suggesting that lα,25-dihydroxy vitamin D(3) partially regulates tether formation in these growth centers via its receptor. In VDR+/+ mice 2-15 weeks in age, growth center thickness was inversely correlated to animal weight whereas tether phenotype (tether volume/growth center volume, tether number/mm, tether width, tether spacing) was significantly related to animal weight. In both 2-15 week old VDR+/+ and 10 week old VDR+/+ and VDR-/- mice on normal and rescue diets, tether phenotype (tether number/mm, tether spacing) had strikingly similar relationships to growth center thickness. These results show that tethers are present in growth centers in different anatomic and undergo developmental changes in a comparable manner; in both sites, VDR-regulated tether formation is strongly linked to growth center morphology; and tether formation is associated with body weight, suggesting a role in maintaining growth plate stability during growth.

Abstract
1Alpha,25-dihydroxyitamin D(3) (1,25D3) deficiency leads to impaired bone mineralization. We used the human pre-osteoblastic cell line SV-HFO, which forms within 19 days of culture an extracellular matrix that starts to mineralize around day 12, to examine the mechanism by which 1,25D3 regulates osteoblasts and directly stimulates mineralization. Time phase studies showed that 1,25D3 treatment prior to the onset of mineralization, rather than during mineralization led to accelerated and enhanced mineralization. This is supported by the observation of unaltered stimulation by 1,25D3 even when osteoblasts were devitalized just prior to onset of mineralization and after 1,25D3 treatment. Gene Chip expression profiling identified the pre-mineralization and mineralization phase as two strongly distinctive transcriptional periods with only 0.6% overlap of genes regulated by 1,25D3. In neither phase 1,25D3 significantly altered expression of extracellular matrix genes. 1,25D3 significantly accelerated the production of mature matrix vesicles (MVs) in the pre-mineralization. Duration rather than timing determined the extent of the 1,25D3 effect. We propose the concept that besides indirect effects via intestinal calcium uptake 1,25D3 directly accelerates osteoblast-mediated mineralization via increased production of mature MVs in the period prior to mineralization. The accelerated deposition of mature MVs leads to an earlier onset and higher rate of mineralization. These effects are independent of changes in extracellular matrix protein composition. These data on 1,25D3, mineralization, and MV biology add new insights into the role of 1,25D3 in bone metabolism and emphasize the importance of MVs in bone and maintaining bone health and strength by optimal mineralization status.

Abstract
The extrarenal synthesis of 1α,25 dihydroxyvitamin D3 (1,25D) has been demonstrated in a number of cell types including osteoblasts and cells of the monocyte/macrophage lineage. The skeleton appears responsive to serum levels of the 1,25D precursor, 25 hydroxyvitamin D3 (25D), in terms of bone mineralization parameters. The effect of metabolism of 25D into active 1,25D by osteoclast lineage cells is unknown. We found that CYP27B1 mRNA expression increased with exposure of human peripheral blood mononuclear cells (PBMCs) to macrophage colony-stimulating factor in the presence or absence of receptor activator of nuclear factor-κB ligand. Consistent with this, human osteoclast cultures incubated with 25D produced measurable quantities of 1,25D. Osteoclast formation from either mouse RAW264.7 cells or human PBMCs in the presence of physiological concentrations of 25D resulted in significant up-regulation of the key osteoclast transcription factor, nuclear factor of activated T cells-c1 in PBMCs and a number of key osteoclast marker genes in both models. The expression of the osteoblast coupling factor, ephrin-b2, was also increased in the presence of 25D. Levels of CYP27B1 and nuclear factor of activated T cells-1 mRNA correlated during osteoclastogenesis and also in a cohort of human bone samples. CYP27B1 short-hairpin RNA knockdown in RAW264.7 cells decreased their osteoclastogenic potential. 25D dose dependently reduced the resorptive capacity of PBMC-derived osteoclasts without compromising cell viability. 25D also reduced resorption by RAW264.7- and giant cell tumor-derived osteoclasts. Conversely, osteoclasts formed from vitamin D receptor-null mouse splenocytes had increased resorptive activity compared with wild-type cells. We conclude that 25D metabolism is an important intrinsic mechanism for optimizing osteoclast differentiation, ameliorating osteoclast activity, and potentially promoting the coupling of bone resorption to formation.

Abstract
BACKGROUND Although pulsed electromagnetic fields (PEMFs) are used to treat delayed unions and nonunions, their mechanisms of action are not completely clear. However, PEMFs are known to affect the expression of certain genes. QUESTIONS/PURPOSES We asked (1) whether PEMFs affect gene expression in human osteoblastlike cells (MG63) in vitro, and (2) whether and to what extent stimulation by PEMFs induce cell proliferation and differentiation in MG-63 cultures. METHODS We cultured two groups of MG63 cells. One group was treated with PEMFs for 18 hours whereas the second was maintained in the same culture condition without PEMFs (control). Gene expression was evaluated throughout cDNA microarray analysis containing 19,000 genes spanning a substantial fraction of the human genome. RESULTS PEMFs induced the upregulation of important genes related to bone formation (HOXA10, AKT1), genes at the transductional level (CALM1, P2RX7), genes for cytoskeletal components (FN1, VCL), and collagenous (COL1A2) and noncollagenous (SPARC) matrix components. However, PEMF induced downregulation of genes related to the degradation of extracellular matrix (MMP-11, DUSP4). CONCLUSIONS AND CLINICAL RELEVANCE PEMFs appear to induce cell proliferation and differentiation. Furthermore, PEMFs promote extracellular matrix production and mineralization while decreasing matrix degradation and absorption. Our data suggest specific mechanisms of the observed clinical effect of PEMFs, and thus specific approaches for use in regenerative medicine.

Abstract
PURPOSE Liver has an important role in metabolism of vitamin D. This study aimed to evaluate the patterns of vitamin D-parathyroid hormone (PTH) disturbance and correlate it in patients with non-cholestatic chronic liver disease (CLD). METHODS A total of 40 healthy controls and 90 consecutive patients with evidence of non-cholestatic CLD due to hepatitis C (n = 28), hepatitis B (n = 26), autoimmune hepatitis (n = 19), and cryptogenic causes (n = 17) were enrolled. Cirrhosis was evident in 51 patients. Serum concentrations of 25-hydroxy vitamin D, PTH, calcium, phosphate, and liver enzymes were measured. Child-Pugh classification was determined in cirrhotic patients. RESULTS Vitamin D deficiency (<50 nmol/l) was found in 46 (51.1%) patients and vitamin D insufficiency (50-80 nmol/l) in 15 (16.7%) patients. Secondary hyperparathyroidism (serum PTH > 6.8 pmol/l) was present in 6 (6.7%) patients. The prevalence of vitamin D deficiency was significantly higher in cirrhotic versus noncirrhotic patients (76.5 vs. 17.9%; P < 0.001), whereas there was no significant difference in serum calcium, phosphate, and PTH levels. Child-Pugh class B and C patients had significantly lower vitamin D level compared with class A patients (P < 0.001), whereas there was no significant difference in serum calcium, phosphate, and PTH levels. No significant correlation was seen between vitamin D and PTH, calcium or phosphate levels. Lower serum level of vitamin D was associated with coagulopathy, hyperbilirubinemia, hypoalbuminemia, anemia, and thrombocytopenia. CONCLUSIONS Vitamin D inadequacy and the severity of liver dysfunction move in parallel in patients with non-cholestatic CLD. Vitamin D assessment and replacement should be considered in the management of patients with non-cholestatic CLD.

Abstract
1,25-dihydroxy-vitamin D3 [1alpha,25(OH)2D3] is a critical regulator of bone development. Protein disulfide isomerase A3 (Pdia3) is a multifunctional protein that has been associated with rapid membrane-initiated signalling by 1alpha,25(OH)2D3 in several cell types. To identify the physiological roles of Pdia3 in skeletal development, we generated Pdia3-deficient mice. No homozygous mice were observed at birth, indicating that the targeted disruption of the Pdia3 gene resulted in embryonic lethality. Pdia3 deficiency also resulted in skeletal manifestations as revealed by muCT analysis of femurs from 15-week-old heterozygous mice. The Pdia3+/- mice had increased metaphyseal bone volume and trabeculae compared to Pdia3+/+ mice. In contrast, the area and thickness of cortical bone at the femoral mid-diaphysis of Pdia3+/+ mice significantly exceeded that of Pdia3+/- mice. In vitro studies in osteoblast-like MC3T3-E1 cells showed that silencing of Pdia3 abolished 1alpha,25(OH)2D3-induced rapid activation of protein kinase C (PKC) while overexpression of Pdia3 resulted in augmentation of PKC activity by 1alpha,25(OH)2D3. Taken together, these data indicated that Pdia3 plays a crucial role in 1alpha,25(OH)2D3-regulated bone formation and the Pdia3-PKC signalling pathway might be involved in this process.

Abstract
Traumatic brain injury is a significant clinical problem for which there is still no effective treatment. Recent laboratory and clinical data demonstrate a potentially beneficial role for neurosteroids, such as progesterone and allopregnanolone, in the treatment of traumatic brain injury, ischemic stroke and some neurodegenerative disorders. Unlike single-target agents, progesterone affects many of the molecular and physiological processes in the cascade of secondary damage after a traumatic brain injury. This article updates a 2006 Future Neurology review of the research on progesterone and its metabolites in the treatment of traumatic brain injury, and presents new evidence that vitamin D deficiency can reduce progesterone neuroprotection, while combining progesterone with vitamin D produces better functional outcomes after TBI compared with eithertreatment alone.

Abstract
BACKGROUND Matrix vesicles have been implicated in the mineralization of calcified cartilage, bone and dentin for more than 40 years. During this period, their exact role, if any in the nucleation of hydroxyapatite mineral, and its subsequent association with the collagen fibrils in the organic matrix has been debated and remains controversial. SCOPE OF REVIEW This review summarizes studies spanning the whole history of matrix vesicles, but emphasizes recent findings and several hypotheses which have been recently introduced to explain in greater detail how matrix vesicles function in biomineralization. MAJOR CONCLUSIONS It is now generally accepted that matrix vesicles have some role(s) in mineralization; that they are the initial site of mineral formation; that MV bud from the plasma membrane of mineral forming cells, but that they take with them only a subset of the materials found in the parent membrane; that the three proteins, alkaline phosphatase, nucleotide pyrophosphatase phosphodiesterase and annexin V have important roles in the process and that matrix vesicles participate in regulating the concentration of PPi in the matrix. In contrast, many open questions remain to be answered. GENERAL SIGNIFICANCE Understanding the role of matrix vesicles in biomineralization will increase our knowledge of this important process.
