    Effects of various p38 MAPK inhibitors on LPS-induced G-CSF mRNA in RAW264.7 and THP-1 macrophages. RAW264.7 cells ( a ) and THP-1 ( b ) were pretreated for 30 min with DMSO or 10 μM SB203580, SB202190, PD169316, SB239063, or SKF86002, then 100 ng/ml of LPS was added and incubation continued for 6 h, then the G-CSF mRNA levels were determined by RT-qPCR, normalized to GAPDH mRNA levels, and expressed relative to the value in the DMSO control, set as 1. The values are the mean ± SD for three separate experiments. * p

    SB202190 enhances cleavage of PARP when combined with glucose analogs. Western blot analysis of whole cell lysates from cells treated for 24 hours with 2-DG or D-allose alone or in combination with SB202190. Lysates were probed for cleaved and total PARP. Tubulin served as a loading control for protein. Cleaved PARP band density was quantified using ImageJ software with normalization to α-Tubulin. One representative experiment is shown, n = 3.

    TcdB, but not latrunculin B, induced IL-8 secretion in HMC-1 cells. TcdB (6 nM) induced the secretion of 605 ± 58 ng per 10 6 cells over 5 h of treatment, whereas controls showed a constitutive secretion of 29 ± 28 ng per 10 6 cells. IL-8 secretion induced by TcdB was prevented in the presence of the p38 MAPK inhibitor SB202190 (58 ± 21 ng per 10 6 cells). In contrast to TcdB, latrunculin B (Lat B; 2 μg/ml) did not induce a strong increase in IL-8 secretion compared to that in controls (52 ± 2 ng per 10 6 cells). Shown are mean values ± standard deviations from six separate experiments.

Immunoblot analysis shows the phosphorylation of p38 MAPK (p-p38) (upper panel) and ERK1/2 (p-ERK1/2) (middle panel). Beta-actin, shown in the lower panel, serves as a control for identical protein loads. (B) Effect of p38 MAPK inhibition by SB202190 (10 μM) on hexosaminidase release induced by TcdB (6 nM) or latrunculin B (2 μg/ml). In comparison to what occurred in control cells (100% ± 34%), the TcdB-induced (288% ± 8%) and the latrunculin B-induced (196% ± 23%) release of hexosaminidase was partially reduced by the p38 MAPK inhibitor SB202190 (TcdB, 236% ± 39%; latrunculin B, 133% ± 11%).

    Techniques: Activation Assay, Incubation, Expressing

    Increasing doses of the p38 MAPK cascade inhibitor, SB202190, and the p42/44 MEK inhibitor, PD98059, inhibited eosinophil chemotaxis. Eosinophils (1 × 10 6 cells) were added with IL-5 (30 ng/ml) to the upper chambers of a transwell plate. Chemotaxis

    Role of MAPK and NF-κB in the mannan induced SBD-1 expression in OREC. A OREC were treated with mannan and harvested at 0, 5, 15, 30, 45, and 60 min. Whole-cell lysates were prepared and used for Western blotting analysis with p38 and p-p38, ERK1/2 and p-ERK1/2, JNK and p-JNK, IκB and p-IκB, p65 and p-p65 antibodies. Protein levels are represented by the value shown in gray for the p-factor/factor. Statistical analyses were performed using the ImageJ software. B Effect of inhibitors on the mannan-induced SBD-1 mRNA expression was determined by qPCR. OREC were cultured with mannan, with or without the SB202190 p38 inhibitor, PD98059 ERK1/2 inhibitor, SP600125 JNK inhibitor, and PDTC NF-κB inhibitor. The relative mRNA abundance was calculated using the 2 −ΔΔCt method relative to β-actin. Data are mean ± SD ( n = 3). Different letters indicate significantly different means ( P
