Article Title: Activation of the Immune-Metabolic Receptor GPR84 Enhances Inflammation and Phagocytosis in Macrophages
doi: 10.3389/fimmu.2018.01419
Figure Lengend Snippet: GPR84 antagonist abrogates the enhanced inflammatory response mediated by 6-OAU. (A) Intracellular cyclic AMP levels were measured in CHO-GPR84 cells pre-treated with the antagonist followed by forskolin and 6-OAU stimulation. Data are represented as the mean ± SEM of the percentage of the response to forskolin in the absence of agonists n = 3 independent experiments. (B–H) Bone marrow-derived macrophages were treated with LPS (0.1 µg/ml) for 2 h before pre-treatment with vehicle (0.3% DMSO), 10 µM antagonist for 30 min, or 200 ng/ml Pertussis toxin for 90 min. Afterward cells were stimulated with either vehicle (0.3% DMSO) or 1 µM 6-OAU for either 10′ for protein isolation or 1 h for RNA extraction. (B) Cell lysates were prepared and western blotting conducted for either phosphorylated Akt (P-AKT) or ERK 1/2 (P-ERK), followed by stripping and re-staining for β-actin as a loading control. Representative images from n = 3 independent experiments. (C–H) mRNA expression of Tnf α (C) , Il-6 (D) , Il-12 (E) , Ccl5 (F) , Ccl2 (G) , and Cxcl1 (H) was analyzed by q-PCR. Data are presented as mean ± SEM of n = 4–7 separate experiments. Statistical significance was assessed using one-way ANOVA with Dunnett’s multiple comparison post hoc test. * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001 versus vehicle; # P ≤ 0.05, ## P ≤ 0.01, ### P ≤ 0.001 versus 6-OAU.

Article Title: Pegylated liposomal-paclitaxel induces ovarian cancer cell apoptosis via TNF-induced ERK/AKT signaling pathway
doi: 10.3892/mmr.2018.8811
Figure Lengend Snippet: ERK/AKT signaling pathway is involved in the activation of the TNF/caspase-3 cascade within ovarian cancer cells. (A) Inhibition of ERKIR decreased caspase-3 expression levels within CAOV-3 cells compared with in the control group. (B) Inhibition of ERKIR inhibited TNF-induced CAOV-3 cell apoptosis compared with in the control group. (C) PL-PTX-induced CAOV-3 cell apoptosis was inhibited via an ERK inhibitor compared with in the control group. **P

Article Title: BACE1 gene silencing alleviates isoflurane anesthesia-induced postoperative cognitive dysfunction in immature rats by activating the PI3K/Akt signaling pathway
doi: 10.3892/mmr.2018.9453
Figure Lengend Snippet: BACE1 gene silencing activates the PI3K/Akt signaling pathway. (A) The mRNA expression of caspase-3 was reduced, and that of PI3K and Akt was increased following reverse transcription-quantitative polymerase chain reaction. (B) The protein expression of caspase-3 was reduced, and that of PI3K and Akt was increased by silencing BACE1, (C) as determined by western blot analysis. *P

Article Title: Astragalus polysaccharide alleviates LPS-induced inflammation injury by regulating miR-127 in H9c2 cardiomyoblasts
doi: 10.1177/2058738418759180
Figure Lengend Snippet: APS reduced LPS-induced inflammation injury by down-regulating miR-127 and inhibiting NF-κB and JNK and promoting PI3K/AKT signaling pathways in H9c2 cells. (a) H9c2 cells were treated with LPS or co-treated with APS and LPS, and then expression levels of miR-127 in H9c2 cells were measured by qRT-PCR. (b)–(d) Protein expression levels of p65/p-p65, lκBα/p-lκBα JNK/p-JNK, c-Jun/p-c-Jun, PI3K/p-PI3K, and AKT/p-AKT were detected by western blot. Different letters above the bars (a, b, c) indicate that the means of different groups were significantly different ( P
