Article Title: Response of chondrocytes to shear stress: antagonistic effects of the binding partners Toll-like receptor 4 and caveolin-1.

doi: 10.1096/fj.11-184861

Figure Lengend Snippet: Figure 3. TLR4 and caveolin-1 exert antagonistic effects on shear-induced IL-6 synthesis in human chondrocytes. T/C-28a2 chondrocytes were subjected to shear stress (20 dyn/cm2) or static conditions (0 dyn/cm2) for 2 h (A, B) or 48 h (C, D). In select experiments, T/C-28a2 chondrocytes were transfected with either a siRNA oligonucleotide sequence specific for TLR4 (A) or caveolin-1 (D) or scrambled siRNA control before their exposure to fluid shear. In separate experiments, cells were transfected with either a plasmid containing the cDNA of caveolin-1 (B) or TLR4 (C) or an empty vector (control) prior to shear exposure. TLR4 (A, C) or caveolin-1 (B, D) and IL-6 protein (top panels) and mRNA expression (bottom panels) were determined by Western blot analysis and qRT-PCR, respectively. -Actin and GAPDH served as internal controls in immunoblotting and qRT-PCR assays, respectively. Western blots are representative of 3 independent experiments, all revealing similar results. Data represent means se of 3 independent qRT-PCR experiments. *P 0.05 vs. static control; ŒP 0.05 vs. shear alone.

Figure Lengend Snippet: Figure 8. Fluid shear induces the binding of the NF-B p65 subunit to the IL-6 promoter in human chondrocytes. T/C-28a2 chondrocytes were subjected to fluid shear stress (20 dyn/cm2) or static conditions (0 dyn/cm2) for 48 h (A, B, F, G) or 2 h (C–E, H–J). In select experiments, T/C-28a2 cells were transfected with the indicated siRNAs or cDNA constructs before exposure to shear stress. In separate experiments, T/C-28a2 cells were subjected to fluid shear stress (20 dyn/cm2) for 2 h in the presence or absence of a MEK1/2 inhibitor [U0126 (10 M) or PD98095 (20 M)]. A–E) Nuclear extracts were then isolated, and NF-B-specific DNA-protein complex formation was determined by gel shift. F–J) Supershift assays using an anti-p65 Ab were carried out as outlined in Materials and Methods. Results of a competition experiment using 200-fold unlabeled NF-B oligonucleotide (cold probe) are shown. Gels are representative of 3 independent experiments, all revealing similar results.

Figure Lengend Snippet: Figure 9. Fluid shear induces the binding of the NF-B p65 subunit to the IL-6 promoter in human chondrocytes. T/C-28a2 cells were subjected to fluid shear stress (20 dyn/cm2) or static conditions (0 dyn/cm2) for 48 h (A, B) or 2 h (C–G). Cells were transfected with the indicated siRNAs or cDNA constructs or treated with prescribed pharmacological inhibitors before exposure to shear stress. Cross-linked chromatin was immunoprecipitated using an antip65 antibody (left panel). In ChIP assays, the anti-RNA polymerase II antibody was used as a positive control, whereas the normal mouse IgG and anti-TLR4 antibodies were used as negative controls. DNA purified from both the immunoprecipitated (IP) and preimmune (input) specimens were subjected to PCR amplification using primers for the GAPDH (control) and p65 promoter genes. All experiments are representative of 3 independent experiments, all revealing similar results.
