This study was performed to evaluate the contribution of adiponectin to the production of interleukin (IL)-6, IL-8, vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-1 and MMP-13 in human endothelial cells and osteoblasts in arthritic joints. Cultured human umbilical vascular endothelial cells (HUVECs) and osteoblasts were stimulated(More)
To evaluate the extent to which fat mass contributes to serum osteopontin (OPN) concentration, we investigated whether serum OPN levels are decreased by exercise-induced fat mass loss and whether they are associated with body fat percentage in obese humans. Twenty‑three female college students were recruited to participate in an 8‑week body weight control(More)
We investigated whether taurine chloramine (TauCl), which is -endogenously produced by immune cells such as macrophages that infiltrate adipose tissue, affects the differentiation of preadipocytes into adipocytes or modulates the expression of adipokines in adipocytes. To study the physiological effects of TauCl on human adipocyte differentiation and(More)
This study was performed to evaluate whether endocan expression, which is known to be involved in tumor angiogenesis, was increased in rheumatoid arthritic tissues. In addition, the involvement of adiponectin in the regulation of endocan expression in arthritic joints was examined. Arthritic synovial tissues from patients with rheumatoid arthritis (RA) or(More)
To examine the possible role of taurine chloramine (TauCl) in modulating the expression of adipokines in adipose tissue associated with obesity, we evaluated the effect of TauCl in human differentiated adipocytes in response to IL-1β. To study the physiological effects of TauCl on adipokine expression, differentiated adipocytes were treated with IL-1β in(More)
Osteopontin (OPN) is known to be significantly involved in the pathogenesis of rheumatoid arthritis (RA). This study aimed to evaluate if the serum concentration of OPN in patients with RA before and after therapeutic treatments was correlated to disease activity and response to therapy. Blood samples from 40 patients with RA were collected at baseline and(More)
The aim of this study was to determine whether disease activity and the type of therapy differentially modulate serum adipokine levels in patients with rheumatoid arthritis (RA), and whether pre-therapy adipokine levels contribute to resistance to treatment. Fasting blood samples from 40 RA patients were obtained at baseline and six months following(More)
In obesity and diabetes, adipocytes show significant endoplasmic reticulum (ER) stress. Hyperglycemia-induced ER stress has not been studied in adipocyte differentiation and adipokine expression. Taurine has been known to protect the cells against ER stress. This study examined the effect of taurine on ER stress-induced adipocyte differentiation and(More)
