Syk

Platelets (3 x 10⁸/mL) were preincubated with Y27632 (10 uM), R406 (1 uM), or a combination of Y27632 and R406 for 20 minutes followed by stimulation with oxLDL (50 ug/mL) for 15 seconds and lysis. Samples were then separated by SDS-PAGE and were immunoblotted for phospho-MLCSer19, followed by reprobing for β-tubulin. (Fi) Representative blots. (Fii) Densitometric analysis of 3 independent experiments. *P < .05. Data are presented as mean ± SEM. Experiments were carried out in the presence of apyrase (2 U/mL), indomethacin (10 uM), and EGTA (1 mM).

BCWM.1 and MWCL-1 cells treated with either vehicle or fostamatinib at the indicated concentrations for two hours, then protein extracts were analyzed by Western blotting for the activation status of MEK, p44/42 MAPK, and Akt with phospho-specific antibodies.

(C) Z-138 and JEKO-1 cells were simultaneously  exposed  to sorafenib and R406  at  the  indicated doses, and cell viability was determined at 48 hours by annexin  V/PI  staining.  Bars represent the mean ± SD of 3 independent experiments. CI value is indicated for each combination. (D)  Primary MCL cells from 7 patients were simultaneously exposed to sorafenib and R406 at the indicated doses for 48 hours, and cell viability was determined as above. Bars represent the mean ± SEM of all the samples analyzed. CI value is indicated for each combination.

Dectin-1 is involved in activation of NLRP3-inflammasome by Malassezia spp. IL-1b secretion from mature human mono-DCs incubated with Syk-inhibitors (piceatannol, R406 or P505), 1 h prior to exposure to medium, MSU, b-glucan, nigericin or live M. furfur (MOI = 10) was determined after 6 h by ELISA.

B cells were stimulated by irradiated CD40L+ L cells. Forward scatter vs. BrdU incorporation analysis (day 5) in the gated CD19+ CLL cells (D). The distribution of cells with high FSC (blasts, right quadrants) and proliferation (BrdU+, upper quadrants) are shown.

Change of protein and mRNA with or without the pretreatment of Syk inhibitors. After pretreated with PRT062607 and Piceatannol for 30 min before A. fumigatus hyphae stimulation, activation of Syk was inhibited by 1 μM PRT062607 (p < 0.05), 2 μM PRT062607 (p < 0.01), 5 μM Piceatannol (p < 0.05), 10 μM Piceatannol (p < 0.01) a compared with untreated cells. mRNA expression of IL-1β, IL-6, IL-8 and CXCL1 induced by A. fumigatus hyphae were significantly suppressed b. mRNA expression of IL-1β, IL-6, IL-8, CXCL1 downregulated significantly by 1 μM PRT062607, 2 μM PRT062607, 5 μM Piceatannol, 10 μM Piceatannol. **means p < 0.01, *p < 0.05.

WT mouse primary macrophages were untreated as control (lane 1) or treated with 0.1μg/ml E. coli LPS (lane 5-8), 10μM E-64 (lane 2 and 6), 250μM PMSF (lane 3 and 7), or 20μM MNS (lane 4 and 8). The cells were continuously cultured for 16 hrs. Extracts from whole cells or nuclei were separately purified and subjected to WB analysis with antibody against pERK2, LITAF, or actin/tubulin as control.

Dose titration effects of sotrastaurin (Sotr), GS-9973 (GS) on GSK-3 and AKT phosphorylation were evaluated in anti-IgM-stimulated CLL cells. One representative experiment out of 3 performed is shown.
