Autophagy modulates osteoarthritis-related gene expression in human chondrocytes.
OBJECTIVE Autophagy, an evolutionarily conserved process for the bulk degradation of cytoplasmic components, serves as a cell survival mechanism. The purpose of this study was to elucidate the role of autophagy in human chondrocytes and pathophysiology of osteoarthritis (OA). METHODS Autophagy in articular cartilage and primary chondrocytes was assessed using antibodies for the autophagy mark...
متن کاملRegulation of c-maf gene expression by Pax6 in cultured cells.
c-Maf is a bZip transcription factor expressed in developmental and cellular differentiation processes. Recently, a c-maf knockout mouse model, showing abnormal lens development, has been reported. In order to study the regulation mechanisms of c-maf gene expression during the differentiation process we have cloned and functionally characterized the rat c-maf (maf-2) gene. The rat c-maf gene is...
متن کاملSUMOylation attenuates c-Maf-dependent IL-4 expression.
The function of transcription factors can be critically regulated by SUMOylation. c-Maf, the cellular counterpart of v-maf oncogene, is a potent transactivator of the IL-4 gene in Th2 cells. We found in a yeast two-hybrid screen that c-Maf can interact with Ubc9 and PIAS1, two key enzymes of the SUMOylation pathway. In this study, we report that c-Maf co-localized with these two SUMO (small ubi...
متن کاملc-Maf regulates IL-10 expression during Th17 polarization.
IL-10 production by Th17 cells is critical for limiting autoimmunity and inflammatory responses. Gene array analysis on Stat6 and T-bet double-deficient Th17 cells identified the Th2 transcription factor c-Maf to be synergistically up-regulated by IL-6 plus TGFbeta and associated with Th17 IL-10 production. Both c-Maf and IL-10 induction during Th17 polarization depended on Stat3, but not Stat6...
متن کاملVitamin C Protects Chondrocytes against Monosodium Iodoacetate-Induced Osteoarthritis by Multiple Pathways
Osteoarthritis (OA) is the most prevalent joint disease. Dietary intake of vitamin C relates to a reduction in cartilage loss and OA. This study examined the efficacy of vitamin C to prevent OA with the in vitro chondrosarcoma cell line (SW1353) and the in vivo monosodium iodoacetate (MIA)-induced OA rat. Results demonstrated that, in SW1353 cells, treatment with 5 μM MIA inhibited cell growth ...
