    Figure Lengend Snippet: Fig. 5. Knockdown of FNDC5 reverses the protective effect of ELK4 on OSAS-related neuroinflammation and cognitive dysfunction. (A) The mean time of escape latency during 5 days of training (F (1, 40) = 469.4, p < 0.0001), mean percentage of time in the target quadrant (t = 21.49, df = 8, p < 0.0001), and mean number of mouse platform crossings on day 6 (t = 4.802, df = 8, p = 0.0014) in the MWM test. (B) The levels of IL-1β (t = 3.102, df = 8, p = 0.0146), IL-6 (t = 3.713, df = 8, p = 0.0059), TNF-α (t = 3.540, df = 8, p = 0.0076), IL-10 (t = 3.452, df = 8, p = 0.0087), TGF-β1 (t = 3.142, df = 8, p = 0.0138), and BDNF (t = 3.309, df = 8, p = 0.0107) in the hippocampal tissues of mice were examined using ELISA. (C) The levels of oxidative stress markers MDA (t = 3.184, df = 8, p = 0.0129), SOD (t = 4.381, df = 8, p = 0.0023), and GSH (t = 4.809, df = 8, p = 0.0013) in the hippocampal tissues of mice were examined. (D) The neuronal pathomorphology in the brain tissues of mice was observed using HE staining. (E) Apoptosis in neurons in the brain tissues of mice was observed using TUNEL (t = 4.674, df = 8, p = 0.0016). (F) Microglial activation in the brain tissues of mice was observed using immunofluorescence staining of Iba1 (t = 7.648, df = 8, p < 0.0001). (G) Irisin contents in the hippocampal tissues of mice were examined using ELISA (F (5, 24) = 27.65, p < 0.0001). For A-C and E-F, unpaired t-test; for G, one-way ANOVA; for A-1, two- way ANOVA. Data are expressed as the means ± SEM; n = 5; *p < 0.05, **p < 0.01, ***p < 0.001.

    Article Snippet: Membranes were blocked in Trisbuffered saline and 5 % skimmed milk for 1 h at room temperature (RM) and incubated overnight at 4◦C using primary antibodies against ELK4 (1/800; 14666–1-AP; ProteinTech Group, Chicago, IL, USA), FNDC5 (1/3000; ab174833; Abcam), and GAPDH (1/5000; ab181602; Abcam).

    Fig. 6. Schematic illustrating the mechanism. Reduced ELK4 expression in OSA reduces FNDC5 transcriptional expression, leading to pro-inflammatory activation of microglia and cognitive dysfunction. OSA progression was alleviated by activating ELK4-mediated FNDC5 transcriptional expression.
