Article Title: Protective Effects of Irisin Against LPS-Induced Intestinal Injury and Its Influence on Gut Microbiota in Septic Mice
doi: 10.2147/JIR.S542608
Figure Lengend Snippet: ( A ) The intestinal apoptosis of mice in each group was detected by TUNEL fluorescent staining. Nuclei were labeled with blue fluorescence (DAPI), and cell apoptosis was labeled with green fluorescence. Scale bar = 100 μm. ( B ) The density of TUNEL-positive cells was analyzed. ( C ) Irisin alleviated bacteremia in septic mice, as assessed by incubating peripheral blood on a blood agar plate. The black arrows in the figure indicate the bacterial colonies. ( D ) The CFU of bacteremia were count and analyzed (CFU/mL). *P < 0.05, **P < 0.01, vs Ctrl group; # P < 0.05, ## P < 0.01, vs LPS group. ( E ) The correlation between endogenous irisin/FNDC5 and various biomarkers in serum and intestinal tissue was evaluated. The Spearman correlation coefficient, which ranges from −1 to 1, is depicted in varying shades of blue, transitioning from light to dark. Specific values are marked in the respective areas, indicating the direction and strength of the correlation between the two variables. The triangles, both black and white, signify that the P-values for these correlations are statistically significant ( ▲ P < 0.05, ▲▲ P < 0.01).
