doi: 10.14336/AD.2025.0474

Figure Lengend Snippet: Stroke increases astrocytic gliosis and induced astrocytic polarization in RTN. (A) RTN chemo-sensitive phox2B-positive neurons (area circumscribed by red solid line) are located ventromedial to the VII, medial to the pyramidal tract. (B) Histological representation of the RTN location within the brainstem, illustrating the specific area analyzed in both WT, CAA, and stroke mice, in relation to the 7th Facial Nucleus (7 N), Scale bar = 300μm/50 μm (zoom). (C-G) Images show the GFAP expression in each group(F (2,18) =19.043, P ＜0.001), and dual-IF staining for GFAP with C3 (F (2,18) =19.851, P ＜0.001 ), GFAP with S100A10 (F (2,18) =21.306, P ＜0.001) in RTN from WT, CAA, and stroke mice at day 42 post-ischemia (n= 5 for WT group, n=7 for CAA-Sham group and n=9 for CAA-pd-MCAO group). Scale bar = 50 µm. * P <0.05; ** P <0.01; *** P <0.001. ns: non-significance. The data are shown as the mean ± SEM. After performing the Shapiro-Wilk normality test to examine the normal distribution, One-way analysis of variance (ANOVA) was employed to analyze the data pertaining to multiple groups, subsequently, multiple comparisons were conducted using the uncorrected Fisher's LSD test.

Article Snippet: Sections were then incubated overnight at 4°C with primary antibodies against Aβ (1:300, Abcam, Cat# ab201060), Phox2B (1:20, Bio-Techne, Cat# AF4940), GFAP (1:200, Novus, Cat# NB100-53809), C3 (1:200, Abcam, Cat# ab97462) S100A10 (1:200, Invitrogen, Cat# PA5-95505), LYVE1(1:200, CST, Cat# E3L3V) and in the blocking solution.

Figure Lengend Snippet: Effect of treatments on neuronal and glial function biomarkers in the prefrontal cortex. (A) BDNF mRNA fold change and (B) GFAP mRNA fold change. Data are represented as mean ± SEM ( n = 7). One-way ANOVA followed by Tukey’s post hoc test. # = vs. Control; $ = vs. SI; @ = vs. SI&RUT-SeNPs; * = vs. SI&OLA; P < 0.05.

Article Snippet: To evaluate astrocytic activation and neuronal survival, paraffin embedded cortical sections were subjected to IHC staining targeting glial fibrillary acidic protein (GFAP) (Cat. No. NB300-141, 1:600, Novus Biologicals, Centennial, CO, USA) and nuclear factor Kappa-B (NF-kB) (Cat. No. NB100-56712, 1:200, Novus Biologicals, Centennial, CO, USA).

Figure Lengend Snippet: RUT-SeNPs protect against GFAP staining in the prefrontal cortex of rats with SI. Photomicrographs of the prefrontal cortex from each group. GFAP immunoreactivity was detected in tissues using DAB chromogen, resulting in a brown color (arrow) (DAB, X400, Scale bar = 50 µm). The control group (A) had normal cortical anatomy and mild GFAP staining. The SI (B) and SI&Na2SeO3-treated (E) groups showed strong GFAP immunostaining. In contrast, the (C) SI&OLA, (D) SI&RUT, and (F) SI&RUT-SeNP-treated groups demonstrated decreased GFAP staining. (G) Quantitative analysis of immunostaining area % for GFAP was expressed as mean ± S.E.M ( n = 7). Statistical analysis by one-way ANOVA with Tukey’s post hoc test. # = vs. Control; $ = vs. SI; @ = vs. SI&RUT-SeNPs; * = vs. SI&OLA; P < 0.05.
