Article Title: Mechanisms of Nifedipine-Downregulated CD40L/sCD40L Signaling in Collagen Stimulated Human Platelets

doi: 10.1371/journal.pone.0127054

Figure Lengend Snippet: Platelets were pretreated with 5 μ M nifedipine or nifedipine combined with various drugs for 3 min followed by addition of collagen for 6 min. The expression of phospho-P38MAPK and total-P38MAPK (A), phospho-ERK1/2 and total ERK1/2 (B), phospho-HSP27 and total-HSP27 (C) were determined. Date were expressed as means ± SEM ( n = 5). *** p < 0.001 compared with collagen alone group; ++ p < 0.01, +++ p < 0.001 compared with respective collagen+nifedipine-treated group.

Article Snippet: The phospho-HSP27, total-HSP27, phospho-p38 mitogen-activated protein kinase (p38MAPK), total-p38MAPK, phospho-ERK1/2, total-ERK1/2 antibodies were purchased from Cell Signaling Technology (Beverly, MA, USA).

doi: 10.1371/journal.pone.0127054

Figure Lengend Snippet: Nifedipine initially activates PPAR-β/-γ followed by increased formation of NO/cyclic GMP and down-regulation of p38MAPK/ERK1/2/HSP27 signaling as well as ROS generation, which then attenuates MMP-2 activity and ultimately inhibits sCD40L release from activated platelets.

Article Title: Inhibition of Ras GTPases prevents Collagen‐Induced Arthritis by Reducing the Generation of Pathogenic CD4 + T Cells and the Hyposialylation of Autoantibodies

doi: 10.1002/acr2.11169

Figure Lengend Snippet: Farnesylthiosalicylate (FTS) inhibits phosphorylation of mitogen‐activated protein kinases (MAPKs) and T‐cell proliferation following T‐cell antigen receptor (TCR) stimulation. Isolated mouse CD4+ T cells were stimulated with anti‐‐CD3/28 antibodies and treated with FTS 10 µM (green) or vehicle (red) for 30 minutes. A , Bar graphs depict the relative phosphorylation level (arbitrary units of intensity per densitometry) of the indicated kinases included in the RayBio Mouse MAPK Pathway Phosphorylation Array, as analyzed per the manufacturer’s protocol. B , Flow cytometry data expressed as overlay histograms depicting phosphorylated (p)‐extracellular signal‐regulated kinase (Erk)1/2, p‐AKT, and p‐p38 levels, determined by phospho‐flow‐cytometry with phospho‐specific antibodies, as detailed in the Methods section. T cells treated with FTS or control media are shown in green and red, respectively, whereas unstained counterpart samples are in grey. C , CD4+ T cells were labeled with carboxyfluorescein succinimidyl ester (CFSE) and activated by plate‐bound anti‐CD3 and soluble anti‐CD28 monoclonol antibodies (mAbs), treated with the indicated concentration of FTS, and cultured for 72 hours. Shown is a representative experiment (CFSE‐dilution flow cytometry histograms) out of two independent experiments, and the bar graphs depict mean ± SD of triplicates. Samples were analyzed for statistical significance by Student's t test (*** P < .001, ** P < .01, and * P < .05).

Figure Lengend Snippet: TPVP-DHA treatment of MIA PaCa-2 cells significantly decreases phosphorylation status of MAPK signaling pathways. MIA PaCa-2 cells were treated with 5 μM of TPVP-DHA for 72 h. Two hundred micrograms of total protein extracts were incubated with RayBiotec MAPK Phosphorylation Arrays following the manufacturer supplied protocol. Chemiluminescence was used to image the membrane and results were quantified using NIH ImageJ software. Images of the original blot and heat maps are shown on left and quantitative results are shown on right. Percent change in MAPK-phosphorylation status was calculated relative to MAPK-phosphorylation in cells treated with 6-TPVP alone.

RayBiotec MAPK Pathway arrays: Asynchronous cultures were treated with 5 μM DHA, 6-TPVP and TPVP-DHA for 72 h. Total protein extracts were prepared following the manufacturer supplied protocol and two hundred microgram of total protein extracts were incubated with RayBiotec MAPK Pathway Phosphorylation Arrays.
