Cell culture supernatant was also collected from pericyte monocultures at the same time point. Supernatant was centrifuged at 4��C for 10?min at 1500?rpm. JNJ-26481585 cell line Protein was quantified using ProStain Protein Quantification kit (Active Motif), and equal amounts of protein were assayed for cytokine and chemokine concentration using a Luminex Magpix multiplexing platform (Luminex Corporation, Austin, TX). Quantification of cytokine/chemokine concentrations in the culture supernatants was carried out with a human cytokine/chemokine 42-plex bead panel (Millipore Corporation, Billerica, MA). Mutiplexing analysis was performed using reagents supplied by Millipore according to the manufacturers recommendations. Briefly, antibody-conjugated magnetic beads were incubated with cell culture supernatants (antigen) in a 96-well format followed by sequential incubations with biotinylated detection antibody and streptavidin-phycoerythrin. Bead complexes were then read on the Magpix multiplex platform (Luminex Corporation). Sensitivity of standards ranged between 3.2 and 10,000?pg/mL, giving a broad range of sensitivity. Standard curves and data analysis was performed PI3K inhibitor using Milliplex Analyst 5.1 software (Millipore Corporation). Statistical analysis A 3-way ANOVA was used to determine differences in NF-��B activation for the main effects of cell type (pericytes versus C2C12), time (BSLN, 3, 6, 24?h), and condition (control versus injured). Two-way ANOVA was used to investigate differences in NF-��B activation of respective cells types over time (BSLN, 3, 6, 24?h) and between conditions (control versus injured). A 2-way ANOVA was used to determine differences in endothelial cell proliferation between conditions (c.a. IKK��, d.n. IKK��, and e.v) and over time (24 and 48?h). Multiplex cytokine data for each individual cytokine of interest were tested for differences among conditions using a 1-way ANOVA. Significant main effects and interactions were investigated using t-tests or Tukey's honest significant difference post hoc test where appropriate. Significance was set a priori at P?(-)-p-Bromotetramisole Oxalate were cocultured with C2C12 myotubes using transwell inserts to examine the time course of pericyte and muscle cell NF-��B activation. In this coculture model, the C2C12 p65 DNA binding activity was significantly elevated at 3?h (2.5-fold, P?=?0.027) and 24?h (3.57-fold, P?=?0.001) relative to BSLN. There was no difference in C2C12 p65 DNA binding activity in INJ compared to CON (P?=?0.698). In the same cocultures, pericyte p65 DNA binding activity was increased relative to BSLN at 6?h (2.0-fold, P?=?0.007), and 24?h (2.33-fold, P?=?0.001). Pericytes trended toward greater p65 DNA binding activity in INJ compared to CON (P?=?0.085). Further, pericytes trended toward greater overall p65 DNA binding activity compared to C2C12 cells (P?=?0.079) (Fig.
