Article Title: Blockage of p38MAPK in astrocytes alleviates brain damage in a mouse model of embolic stroke through the CX43/AQP4 axis.
Article Snippet: Background: Cerebral edema, a significant complication arising from acute ischemic stroke (IS), has a critical influence on morbidity and mortality. p38MAPK has been shown to promote neuronal apoptosis and brain damage.. However, the role of the p38MAPK inhibitor SKF-86002 in protecting against ischemic injury and cerebral edema remains unclear.. Methods: Infarct area was examined by TTC staining in middle cerebral artery occlusion (MCAO) mice.

Article Title: Inhibition of p38α MAPK restores neuronal p38γ MAPK and ameliorates synaptic degeneration in a mouse model of DLB/PD
Article Snippet: .. Both non-tg and α-syn tg mice were treated with SKF-86002 (20 mg/kg; MedChemExpress, Monmouth Junction, NJ), which was dissolved in 10% dimethyl sulfoxide (DMSO) (non-tg, n = 6; α-syn tg, n = 5 for cohort 1; non-tg, n = 10; α-syn tg, n = 8 for cohort 2) or vehicle control 10% DMSO (vehicle) (non-tg, n = 7; α-syn tg, n = 6 for cohort 1; non-tg, n = 9; α-syn tg, n = 9 for cohort 2) and administered five times per week for 12 weeks by intraperitoneal injection. ..

(I) The effect of SKF83566 on human NSCs proliferation in the presence of JNK inhibitor SP600125. (J) The effect of SKF83566 on human NSCs proliferation in the presence of ERK inhibitor PD98059. (K, L) The number of secondary neurospheres formed from SKF83566-treated control or p38 MAPK-knockdown NSCs. For B, D, F-J, N = 3 independent experiments. Data are mean ± SEM. ***P < .001, **P < .01, *P < .05, 2-way ANOVA, followed by Tukey’s multiple comparisons test.

Article Snippet: SKF83566 was purchased from Tocris Bioscience; ESI-05, HJC0350, SB203580, SKF86002, PD98059, SP600125 were purchased from MedChemExpress; Cell CountingLite 2.0 Luminescent cell viability assay was purchased from Vazyme.

Techniques: Control, Knockdown

Stimulation of human PBMCs with spike glycoprotein S1 (100 ng/mL) for 60 min activated p38 MAPK and was inhibited by treatment with dexamethasone (100 nM) or SKF 86002 (1 μM). Values are mean ± SEM for at least 3 independent experiments (** p < 0.01; **** p < 0.0001, compared with unstimulated control or spike glycoprotein S1 stimulation; one-way ANOVA with post-hoc Tukey’s test).

Article Snippet: The following drugs were used: BAY11-7082 (Sigma), CRID3 sodium salt (Tocris), SKF 86002 dihydrochloride (Tocris) and dexamethasone (Sigma).

Techniques:

Effects of pre-treatment with BAY11-7082 (1 μM), SKF 86002 (1 μM) and CRID3 (1 μM) on TNFα ( a ), IL-6 ( b ), IL-1β ( c ) and IL-8 ( d ) production in human PBMCs. Culture supernatants were collected following stimulation for 24 h and analysed using human ELISA kits for TNFα, IL-6, IL-1β and IL-8. Values are mean ± SEM for at least 3 independent experiments (ns: not significant; ### p <0.001 versus unstimulated control; #### p < 0.0001 versus unstimulated control; * p < 0.05; ** p < 0.01; *** p < 0.001, compared with spike glycoprotein S1 stimulation; one-way ANOVA with post-hoc Tukey’s test).
