To evaluate the effects of vitamin B6 in cartilage cells, we treated differentiated mesenchymal stem cells and the SW1353 chondrosarcoma cell line with vitamin B6 in the presence of IL1β, the inflammatory cytokine involved in OA.
Therefore, the inhibitory effects of single compounds isolated from RPH on the OA-related molecules were investigated using IL-1β-stimulated chondrosarcoma SW1353 (SW1353) cell model.
Human SW1353 chondrosarcoma cells were treated with IL-1β to mimic the OA-like chondrocyte injury in vitro, and Western blot was employed to examine the IL-1β-induced expression of VPS4B, phosphorylated p38, and apoptotic markers, namely active caspase-3 and cleaved poly (ADP-ribose) polymerase (PARP).
To evaluate the prophylactic function of DHA in OA, the effect of DHA on cartilage degeneration was assessed in interleukin‑1β (IL‑1β) stimulated human chondrosarcoma SW1353 cells or a rat model of adjuvant‑induced arthritis (AIA).
Using human SW1353, HS.819.T and CH2879 chondrosarcoma cell lines as model systems, we found that fluid shear stress induces the accumulation of cyclic AMP (cAMP) and interleukin-1β (IL-1β), which in turn markedly enhance chondrosarcoma cell motility and invasion via the induction of matrix metalloproteinase-7 (MMP-7).
In the present study, the OUMS-27 chondrocytic human chondrosarcoma cell line was treated with IL-1β with or without inhibitors of NF-κB signaling pathways.
Effects of icariin on the regulation of the OPG-RANKL-RANK system are mediated through the MAPK pathways in IL-1β-stimulated human SW1353 chondrosarcoma cells.
POMC gene transfer reduced nuclear factor-κB activity and the levels of interleukin-1β in HTB-94 chondrosarcoma cells and Raw 264.7 macrophages; it also reduced microvessel density in the synovium.
Here, to establish the signaling pathway to MMP-13 induction, effects of mitogen-activated protein kinase (MAPK) pathway and the possibility of some other signaling pathways involved are investigated in interleukin-1β (IL-1β)-treated human chondrosarcoma cell line, SW1353 cells.
It has also been characterized to be reactive and highly activated ADAMTS by IL-1 beta in both chondrosarcoma cells and human chondrocytes (Demircan et al.Arthritis Rheum 52:1451-1460, 2005).
SW-1353 human chondrosarcoma cells were used to study the effects of LG268 on interleukin-1beta (IL-1beta)-stimulated MMP production and collagen degradation.
Primary human adult articular chondrocytes and chondrosarcoma cell line HCS-2/8 were used to study changes in gene expression levels after stimulation with interleukin-1beta and bone morphogenetic protein, as well as the dependence on cell differentiation.
In the present study, using Affymetrix oligonucleotide array technology and real-time quantitative RT-PCR we have investigated the molecular mechanisms underlying the differential effect of IL-1 and TNF-alpha on gene expression in the human chondrosarcoma cell line, SW1353.
Human chondrosarcoma cells stimulated with inflammatory cytokines (interleukin-1beta [IL-1beta], tumor necrosis factor alpha) were used to study the effects of CDDO on the induction of MMPs and the invasion of cells through a collagen matrix.
To detect the message for membrane type 1 (MT1) matrix metalloproteinase (MMP) in articular cartilage and chondrosarcoma cells, to study its expression in osteoarthritis (OA), and to determine whether interleukin-1beta (IL-1beta) influences its expression.
