4.Effect of high-fat diet on rabbit knee articular cartilage
Chinese Journal of Tissue Engineering Research 2014;(42):6775-6778
BACKGROUND:The increase of serum cholesterol levels is positively correlated with the increasing incidence of osteoarthritis. Little is known about the role of high-fat diet in the degeneration of articular cartilage and induced arthritis.
OBJECTIVE:To observe the morphology change of the articular cartilage of New Zealand rabbits after high-fat diet, and explore the role of food in the articular cartilage degeneration.
METHODS:Forty New Zealand white rabbits were randomly divided into two groups. In control group, rabbits were fed with basal diet. In high-fat diet group, rabbits were fed with high-fat diet (20%lard and 80%basal diet). Fasting blood samples was taken every 4 weeks, to detect the triglyceride and total cholesterol levels. After rabbit were fed for 28 weeks, the knee joint was grossly observed and the femoral condyle cartilage was scanned by scanning electron microscope.
RESULTS AND CONCLUSION:Compared with the control group, the triglyceride and total cholesterol levels were significantly increased in the high fat group (P<0.05). Under scanning electron microscope, the high-fat group showed rough surface of condylar cartilage, shal ow pouch, messy arrangement, irregular shape and uneven size. The surface of cartilage exhibited focal denudation, irregular arrangement, uneven porosity and fractured cavity. Under higher magnification, smal mountain-like structure of cartilage surface became shal ow and flattened, the pores disappeared. Long-term high-fat diet may induce and aggravate cartilage damage, suggesting it may be involved in the pathogenesis of osteoarthritis.

9.Noncompetitive antagonists and agonists of glutamate receptor regulate filopodia formation in epidermal cells and melanosome transfer: an experimental study
Chinese Journal of Dermatology 2013;46(12):871-876
Objective To investigate the regulatory effect of glutamate signaling pathway on filopodia formation in epidermal cells and on melanosome transfer.Methods Epidermal melanocytes and keratinocytes were isolated from human foreskin and subjected to subculture.After two to three passages of subculture,the melanocytes and keratinocytes were cultured alone or in combination with or without the presence of MK801 (an antagonist of N-methyl-D-aspartic acid (NMDA) receptor) of 100 μmol/L,or NMDA (the activator of NMDA receptor) of 100 μmol/L,for 24 hours.The melanocytes irradiated with UVB at 311 nm served as the control.Scanning electron microscopy was used to observe the appearance of filopodia and dendrites of melanocytes and keratinocytes.Melanosome transfer was visualized under confocal laser scanning microscopy after double immunofluorescent staining.Results Although no obvious changes were observed in the number of dendrites in monocultured melanocytes after treatment with MK801 or NMDA for 24 hours,dendrites became thinner at the terminus and longer with a decrease in the number and length of filopodia after MK801 treatment,but thicker and shorter with an increase in the number and length of filopodia after NMDA treatment compared with untreated monocultured melanocytes.In the coculture system,filopodia were observed between the untreated melanocytes and keratinocytes,and the number of filopodia in melanocytes was larger in the side adjacent to keratinocytes than in the opposite side.Compared with the untreated coculture system,the number of both filopodia connecting melanocytes and keratinocytes and filopodia extending from melanocytes to keratinocytes decreased in the coculture system after treatment with MK801 of 100 μmol/L,but increased after treatment with NMDA of 100 μmol/L,for 24 hours.Melanosomes were found in keratinocytes cocultured with melanocytes without treatment,which were decreased in number after 24-hour treatment with MK801 of 100 μmol/L,but increased in number and even present in keratinocytes nonadiacent to melanocytes after 24-hour treatment with NMDA of 100 μmol/L.Conclusion Glutamate signaling pathway may modulate the transfer of melanosomes from melanocytes to keratinocytes via modulating the appearance of melanocyte dendrites and formation of filopodia.
