Prostate cancer (PCa) is the most common cancer type in older men and often metastasizes to bone in advanced stages. Wnt proteins are implicated in carcinogenesis and especially WNT5A has been discussed to influence the clinical outcome of various cancer types, including PCa. In addition, WNT5A stimulates osteogenic differentiation and may thus not only be involved in PCa development, but also in the formation of subsequent skeletal metastasis. Here, we determined the role of ...

BMP6 is a member of the TGFβ superfamily with a high potential to induce new bone formation. Recently, we discovered that blood coagulum from the patient’s own blood (WBCD) modified with calcium salts serves as an appropriate autologous carrier for BMPs (OSTEOGROW device). Preclinical experiments indicate that BMP6 is efficacious when used in a significantly lower amounts than BMP2 and BMP7. Besides testing its osteogenic activity, we also tested the influence of the...

Rheumatoid arthritis (RA) is characterised by periarticular bone destruction leading to permanent disability. Some other forms of arthritis, such as arthritis in systemic lupus erythematosus (SLE), rarely produce bone lesions. Corresponding to that, inactivation of Fas produces a murine SLE-like phenotype, but alleviates bone loss during antigen-induced arthritis (AIA). Aim of this study was to identify cell populations differentially regulated in non-resorptive vs. resorptive...

Urolithiasis is characterized by formation and retention of solid crystals within the urinary tract. There are numerous causes that may lead to urinary stone formation. However, kidney stones are mostly composed of calcium oxalate that predominantly generates free radicals that are toxic to renal tubular cells.The aim of the study is to explore the toxic effect of oxalate to renal epithelial cells and to explore possible effects of antioxidants on its in...

Objectives: This cross-sectional study was done in order to assess the prevalence and determinants of vitamin D deficiency in children taking in account the following parameters: children’s age, season, geographic region and ethnicity.Methods: A cross-sectional prospective study was conducted in Israeli children aged 0–18 from Meuhedet Health Services during the year of 2016 in primary care pediatric clinics throughout all different geographic ...

To further characterize the role of serotonin (5HT) in bone metabolism, Wistar-Zagreb rat model consisting of the high-5HT and low-5HT subline with different platelet 5HT content and transporter (5HTT) activity has been used.Primary osteoclasts from the high-5HT subline had an increased expression of 5HTT, 5HT–2A receptor, Trap and cathepsin K, while osteoblasts showed no difference in the expression of 5HT elements or osteoblastic markers. However,...

Background: Pathophysiological calcification in the vasculature is a risk factor for cardiovascular disease (CVD). CVD are among the most common causes of death in patients with chronic kidney disease and crucial for kidney transplantation (RTX) outcomes.Aim: The aim of this study is to identify differences in the pattern and the onset of expression of regulators of calcification (RC) in atherosclerosis (AS) and media sclerosis (MS).<p class="abstext...

Glucocorticoids (GCs) are widely used to treat chronic inflammatory diseases such as rheumatoid (RA) and lead to multiple side effects including glucocorticoid induced osteoporosis (GIO). Our work challenges the dogma that transrepression of pro-inflammatory genes by the glucocorticoid receptor (GR) is solely responsible for reducing inflammation, whereas transactivation of genes is causing side effects.Using conditional and function selective mutant mic...
