Evaluation of gene expression by real time PCR TLR 2 and 4 PCR primers were used. Quantitative amounts of each gene were standardized against the GAPDH housekeeping gene. Real-time PCR was performed using

a BioRad MiniOpticon System (BioRad Laboratories, Ltd.) with a SYBR green fluorophore. Reactions were performed in a total volume of 20 μl, including 10 μl of 2x SYBR Green PCR Master Mix, 1 μl of each primer at 10 ng, and 1 μl of the previously reverse-transcribed GW 572016 cDNA template. The protocols used were as follows: PF-3084014 solubility dmso denaturation (95°C for 10 min), and amplification repeated 40 times (95°C for 30 s, 52°C for 30 s, 72°C for 30 s, and acquisition temperature for 15 s). Statistical analysis All data are expressed as the mean ± standard deviation (SD) and were representative of at least two different experiments. Comparisons between individual data points were made

using the Student’s t-test and performed using one-way ANOVA analysis (Least Significant Difference (LSD) as post-hoc test). Throughout the figures and legends, the following terminology was used to denote statistical significance:**, p < 0.01, *, p < 0.05.
