Figure Lengend Snippet: Effect of NAM on the brain NAD+ content and acetylated form of NFκB (p65) in brains of STZ-induced diabetic mice. ( a ) Brain NAD+ content. ( b ) Relative protein abundance of the acetylated NFκB (p65) obtained by western blot analysis and representative images of brain acetylated NFκB (p65) in each condition. ( c ) Relative protein abundance of the acetylated NFκB (p65) obtained by IHC analysis and representative images of brain acetylated NFκB (p65) in each condition. Abbreviations used: NAD+, oxidized form of nicotinamide adenine dinucleotide; NAM LD, low-dose, NAM-treated, diabetic mice; NAM HD, high-dose, NAM-treated, diabetic mice; non-T1D, group of mice without T1D; T1D, group of mice with T1D. Data are expressed as the mean (standard deviation) of 4–5 mice/group. Images of 10 randomly selected fields were used for quantification. The scale bar shown in the images represents 100 µm. Statistically significant differences among groups for each variable were determined using a parametric ANOVA test followed by Tukey’s posttest. Differences were considered significant when p -value < 0.05. Specifically, * p -value < 0.05 vs. non-diabetic group; † p -value < 0.05 vs. diabetic group.

Figure Lengend Snippet: Relationship between relative NAD+ content and biomarkers of inflammation and microglial activation in brains from diabetic mice. ( a ) Correlation between relative levels of brain NAD+ content and IHC protein abundance of brain NFκB (p65). ( b ) Correlation between relative levels of brain NAD+ content and IHC protein abundance of brain acetyl-NFκB (p65). ( c ) Correlation between relative levels of brain NAD+ content and IHC protein abundance of brain IBA-1. ( d ) Correlation between relative levels of brain NAD+ content and IHC protein abundance of brain BDKRB-1. ( e ) Correlation between relative levels of brain NAD+ content and IHC protein abundance of brain TNFα. ( f ) Correlation between relative levels of brain NAD+ content and IHC protein abundance of brain F4/80. The relationship between parameters was tested using a parametric Pearson’s correlation test. The relative levels of brain NAD+ were calculated taking as 1 the mean of individual values for this parameter in untreated diabetic mice. Mice of all groups were considered for analysis.

Article Title: White spot syndrome virus (WSSV) modulates lipid metabolism in white shrimp

doi: 10.1038/s42003-023-04924-w

Figure Lengend Snippet: The indicated tissues of PBS-injected and WSSV-injected shrimp were collected at 12 hpi and 24 hpi and subjected to a , b lipase activity measurement and ( c ) free fatty acid quantification. Lipase activity was increased in infected hepatopancreas at 12 hpi. Free fatty acids were increased in hemocytes and hemolymph at 12 hpi, whereas a significant decrease of free fatty acids was found in infected hepatopancreas at 24 hpi. Each bar represents mean ± SD, n = 2 ~ 3 pool samples (3 shrimp per pool). Asterisks indicate differences between WSSV and PBS groups (* p < 0.05, ** p < 0.01). Hcy hemocytes, Hly hemolymph, Stm stomach, Hep hepatopancreas.
