Abstract
Objectives: To explore the molecular mechanisms in which vitamin D (VD) regulates T cells, especially Th17 cells in collagen-induced arthritis (CIA). Methods: DBA1/J mice induced for CIA were intraperitoneally treated with VD. CIA clinical symptoms and inflammatory responses including Th1/Th17/Tregs percentages were determined and compared. Mouse naïve CD4+ T cells transduced with miR-124 inhibitor or not were polarized to Th17 cells with or without VD. Subsequently, cellular differentiation and IL-6 signaling moleculars were analyzed. Results: VD treatment significantly delayed CIA onset, decreased incidence and clinical scores of arthritis, downregulated serum IgG levels and ameliorated bone erosion. VD downregulated IL-17A production in CD4+ T cells while increased CD4+Foxp3+Nrp-1+ cells both in draining lymph nodes and synovial fluid in arthritic mice. VD inhibited Th17 cells differentiation in vivo and in vitro and potentially functioning directly on T cells to restrain Th17 cells through limiting IL-6R expression and its downstream signaling including STAT3 phosphorylation, while these effects were blocked when naïve CD4+ T cells were transduced with miR-124 inhibitor. Conclusions: VD treatment ameliorates CIA via suppression of Th17 cells and enhancement of Tregs. miR-124-mediated inhibition of IL-6 signaling, provides a novel explanation for VD's role on T cells in CIA mice or RA patients and suggests that VD may have treatment implications in rheumatoid arthritis.

Oelzner P, Petrow PK, Wolf G, Bräuer R. 1,25-Dihydroxyvitamin D3 prevents bone loss of the secondary spongiosa in arthritic rats by an increase of bone formation and mineralization and inhibition of bone resorption. BMC Musculoskelet Disord 2014; 15:345. [PMID: 25315028 PMCID: PMC4210592 DOI: 10.1186/1471-2474-15-345] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2014] [Accepted: 09/22/2014] [Indexed: 02/07/2023] Open
Abstract
Background Active vitamin D metabolites have been shown to have protective effects in experimental arthritis especially when used as preventive treatment. However, because the direct effects of 1,25-dihydroxyvitamin D3 (1,25(OH) 2D3) on bone formation and resorption are very complex, the net effect of 1,25(OH)2D3 on histomorphometric parameters of bone turnover and mineralisation should be investigated. Therefore, we examined the influence of 1,25(OH)2D3 therapy on arthritis-induced alterations of periarticular and axial bone as well as disease activity, inflammation and joint destruction in antigen-induced arthritis (AIA) of the rat. Methods AIA was induced in 20 eight-week-old female Wistar rats. 10 rats without arthritis were used as healthy controls. AIA rats received 1,25(OH)2D3 (0.2 μg/kg/day, i.p., n = 10) or vehicle (n = 10) at regular intervals for 28 consecutive days beginning 3 days before arthritis induction. Bone structure of the secondary spongiosa of the periarticular and axial bone was analyzed using histomorphometry. Parameters of mineralization were investigated using tetracycline labelling. Clinical disease activity, inflammation and joint destruction were measured by joint swelling and histological investigation, respectively. Results AIA led to significant periarticular bone loss. 1,25(OH)2D3 treatment resulted in a highly significant increase in trabecular bone volume and bone formation rate in comparison to both vehicle-treated AIA and healthy controls at periarticular (p < 0.01 and p < 0.001, respectively) and axial bone (p < 0.001 and p < 0.001, respectively). In addition, bone resorption was reduced by 1,25(OH)2D3 at the axial bone (p < 0.05 vs. vehicle-treated AIA). Joint swelling as well as histological signs of inflammation and joint destruction were not influenced by 1,25(OH)2D3. Conclusions The results of the study indicate a marked osteoanabolic effect of 1,25(OH)2D3 presumably due to a substantial increase in mineralization. Thus, 1,25(OH)2D3 may be an effective osteoanabolic treatment principle to antagonize the inflammation-associated suppression of bone formation in rheumatoid arthritis.

Abstract
The effect of milk extract of Semecarpus anacardium Linn. nut milk extract (SA) was studied to gain some insight into this intriguing disease with reference to collagen metabolism. Arthritis was induced in rats by injecting Freund's complete adjuvant containing 10mg of heat killed mycobacterium tuberculosis in 1 ml paraffin oil (0.1 ml) into the left hind paw of the rat intradermally. After 14 days of induction, SA (150 mg/kg body weight/day) was administered orally by gastric intubations for 14 days. Decreased levels of collagen and glycosaminoglycans (GAGS) components (chondroitin sulphate, heparan sulphate, hyaluronic acid) and increase in the levels of connective tissue degrading lysosomal glycohydrolases such as acid phosphatase, beta-glucuronidase, beta-N-acetyl glucosaminidase and cathepsin-D observed in arthritic animals were reverted back to near normal levels upon treatment with SA. The drug effectively regulated the uriniray markers of collagen metabolism namely hexosamine, hexuronic acid, hydroxyproline and total GAGS. Electron microscopic studies also revealed the protective effect of SA. Hence, it can be suggested that SA very effectively regulate the collagen metabolism that derange during arthritic condition.

Abstract
Localised bone loss in the form of bone erosions and peri-articular osteopenia constitutes an important criteria for the diagnosis of rheumatoid arthritis. In the present study, the effect of Semecarpus anacardium Linn. nut milk extract (SA) on the metabolism of bone turn over has been studied by analyzing various markers of bone turnover and by histological and radiological analysis of the joints in adjuvant arthritis in rats. Arthritis was induced in rats by injecting Freund's complete adjuvant containing 10mg of heat killed mycobacterium tuberculosis in 1 ml paraffin oil (0.1 ml) into the left hind paw of the rat intradermally. After 14 days of induction, SA (150 mg/kg body weight/day) was administered orally by gastric intubations for 14 days. SA significantly reverted the alterations in the bone turnover observed in arthritic animals by modulating the levels of calcium, phosphorus and the activities of the enzymes names tartrate resistant acid phosphatase, acid phosphatase and alkaline phosphatase. The drug increased the bone weights that were found to be decreased during arthritis. Protective effect of SA was also observed by the decrease in the levels and expression of tumour necrosis factor alpha (TNF-alpha) as well as the histopathological and radiological observations. From all these observations it can be concluded that SA possesses strong anti-arthritic property by regulating bone turnover.

Abstract
This study was designed to determine the effect of bone resorption on the development of generalized osteopenia in adjuvant-induced arthritic rats. Thirty of a total of sixty male SD rats, 6 weeks of age, were injected with killed mycobacterium butyricum suspended in mineral oil into the right hind paw and assigned to six groups of 5 animals each. The other thirty animals served as the age-matched noninjected controls. Animals were sacrificed at 4, 7, 10, 14, 21, and 28 days post-injection after measuring the bilateral hind-paw volumes. Twenty-four-hour urinary samples were obtained before sacrifice and the levels of deoxypyridinoline (D-Pyr) and creatinine (CR) were measured. Plasma intact osteocalcin levels were measured by a sandwich enzyme immunoassay at the start, 14 and 28 days after injection. Bone mineral measurement and histomorphometrical analyses were performed on specimens of the third lumbar vertebral body. On the seventh day after injection, arthritic rats showed significant decreases in the values of bone mineral content (BMC) and density (BMD) when compared to controls. Urinary D-Pyr/Cr ratios, however, did not increase on the seventh day, showing a significant increase on the tenth day after injection. The serum osteocalcin level was significantly reduced on the fourteenth day. The trabecular bone volume (BV/TV) in the arthritic rats showed a significant decrease from the seventh day. The trabecular thickness (Tb.Th) value significantly decreased on the seventh day after injection.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A specific HPLC system was developed to assess urinary excretion of collagen crosslinks (pyridinoline (Pyr) and deoxypyridinoline (D.Pyr)) in two models of osteopenia in rats, ovariectomy and adjuvant polyarthritis. The sensitivity of this method was in the picomolar range. In ovariectomized rats, a specific model of bone resorption, Pyr and D.Pyr levels rose early, reaching a peak 2 weeks after surgery. Both levels remained raised during the whole observation period (6 weeks) with no change in the Pyr/D.Pyr ratio. So, in this high bone turnover model, hyperresorption is reflected by the parallel increase of both crosslinks resulting in a significant decrease of bone mineral density (BMD) at 6 weeks (-7.3% vs. control). In polyarthritic rats, in the 2 post-adjuvant weeks, Pyr levels increased in parallel with inflammatory parameters, whereas D.Pyr levels remained unchanged. This is in agreement with our previous report that at the end of the 2nd week after adjuvant there is no change in bone resorption. From the 3rd week, both Pyr and D.Pyr increased. The Pyr/D.Pyr ratio was always significantly higher in polyarthritic rats. These results suggest that the early increase of Pyr level reflects non-osseous collagen breakdown and that bone resorption occurs at a later stage when D.Pyr rises, leading to a dramatic decrease of BMD at 4 weeks (-17.7% vs. control). Taken together, our results suggest that in rat as in human, urinary Pyr is a marker of bone and cartilage breakdown, whereas D.Pyr is a specific marker of bone loss. This automated method described may constitute a very useful tool to evaluate bone and/or cartilage breakdown in rats and for the assessment of protective treatments.

Abstract
Adjuvant polyarthritis (AP) in rats is known to result in extensive bone loss. This study investigates the mechanisms responsible for the early trabecular osteopenia evaluated at a single point in time--2 weeks after adjuvant injection--in the hindpaw of female Lewis rats using biochemical and histomorphometric methods. At this early point in time, the inflammation was generalized (inflammatory score, 20; albumin/globulin, -80% versus control). Histomorphometric analysis of the noninjected femur showed that the trabecular bone volume was significantly decreased (-28% versus control) in both proximal and distal parts, and the femur growth rate was unaffected. The trabecular osteopenia was associated with a 90% decrease in osteoid surface and a concomitant thinning (-19%) of the trabeculae. Both the double-fluorescence-labeled surface and the osteoblast surface were also markedly decreased (-75%). In addition, the mineral apposition rate was reduced (-50%) and the bone formation rate was decreased by as much as 90%. The trabecular bone volume was decreased in relation with the extent of double-fluorescence labeling (r = 0.38, p = 0.03) and bone formation rate (r = 0.42, p = 0.01), suggesting that the generalized osteopenia resulted from the reduced bone formation. This was associated with a 26% reduction in plasma osteocalcin. Neither the osteoclast surface nor the number of osteoclasts was consistently affected. However, urinary hydroxyproline was increased by 100-200%, which likely reflected the cartilage and bone destruction at the site of injection. The present data show that the early extensive osteopenia observed 2 weeks after AP induction in rats results from defective bone formation with unchanged bone resorption. The role of cytokines in such an inhibitory effect on bone formation remains to be determined.

Abstract
The ability of the new nitrogen-containing bisphosphonate disodium-1-hydroxy-3-(1-pyrrolidinyl)-propylidene-1,1-bisphosphona te (EB-1053) to inhibit osteoclastic resorption was examined in vitro and in vivo. Results were compared to those obtained with 3-amino-1-hydroxypropylidene-1,1-bisphosphonate (pamidronate or APD). In vitro, when tested in osteoclast precursor-dependent systems (fetal mouse metacarpals and a coculture system), EB-1053 suppressed 45Ca release effectively and was found to be about 10 times more potent than pamidronate (ED50 = 2.5 x 10(-7) versus 2.5 x 10(-6) M, respectively). The EB-1053-inhibited osteoclastic resorption could be reversed by treatment with parathyroid hormone (PTH). In vivo, daily subcutaneous injections of EB-1053 to young growing rats for 7 days increased metaphyseal bone mass in tibiae dose dependently. In these experiments EB-1053 was about 50 times more potent than pamidronate. These studies show that EB-1053 is a very potent bisphosphonate that has potential use in the treatment of skeletal disorders.

Abstract
MC 903 is a novel vitamin D analogue which has been tested for its effects on cell differentiation and cell proliferation in vitro using the human histiocytic lymphoma cell line U937, and on calcium metabolism in rats in vivo. In the present investigation MC 903 was compared to the natural metabolite of vitamin D3, 1 alpha,25-dihydroxycholecalciferol [1,25(OH)2D3] and to its synthetic analogue 1 alpha-hydroxycholecalciferol [1 alpha (OH)D3]. MC 903 was found to be a potent inducer of cell differentiation and to inhibit cell proliferation and DNA-synthesis in concentrations comparable to those observed with 1,25(OH)2D3. 1 alpha (OH)D3, which is only active after metabolic conversion to 1,25(OH)2D3, was more than 100 times less potent. Oral or intraperitoneal administration of MC 903 to rats showed that the compound was at least 100 times less active than 1,25(OH)2D3 and 1 alpha (OH)D3 in causing hypercalciuria, hypercalcemia and bone calcium mobilisation. The low vitamin D activity of MC 903 was further confirmed by administration of the compound to rachitic rats. The strong direct effects of MC 903 on cell proliferation and cell differentiation, coupled with its decreased activity as a classical vitamin D makes this compound an interesting candidate for studies in human proliferative disorders such as psoriasis.
