Figure Lengend Snippet: Fgl1 upregulation in WAT and liver in mice models of cancer cachexia. ( A ) Interventional design for B16F10 cachexia mouse model studies. ( B ) Tumor weight of B16F10 mice on day 18 after cell injection ( n = 3 per group). ( C ) Tumor-free body weight of PBS and B16F10 injected mice on day 18 ( n = 3 per group). ( D , E ) RNA-seq design and analysis ( n = 3 per group). ( F ) KEGG pathway analysis of RNA-seq data ( n = 3 per group). ( G ) mRNA expression of Fgl1 in eWAT. The expression of each gene was normalized to actin. ( n = 3 per group). ( H ) Protein expression of Fgl1 in eWAT. ( n = 3 per group). ( I ) Gene expression of FGL1 in the spleen, muscle, kidney, lung, liver, stomach, and intestine from the mice ( n = 3 per group). All values are presented as mean ± standard error of the mean (SEM). P values were determined by two-tailed Student’s t-test, with * p < 0.05, ** p < 0.01, and *** p < 0.001 indicating different levels of statistical significance compared to control. ns, not significant

Article Snippet: The B16F10 cell line was maintained in Dulbecco’s Modified Eagle Medium (DMEM, Sangon Biotech, E600003) supplemented with 10% fetal bovine serum (FBS, Sangon Biotech, E600052) and 1% penicillin-streptomycin (P/S, Sangon Biotech, E607011).

Figure Lengend Snippet: Early treatment with FGL1 was effective in promoting tumor growth, while intermediate and late-stage treatment exhibited little effect. ( A ) Experimental design of FGL1 treatment time point. ( B ) FGL1-fc injection on day 7 promotes B16F10 growth ( n = 5 per group). ( C ) FGL1-Fc injection on day 14 does not impact B16F10 growth ( n = 5 per group). All values are presented as mean ± SEM. P values were determined by one-way analysis of variance (ANOVA), with * p < 0.05, ** p < 0.01, and *** p < 0.001 indicating different levels of statistical significance compared to control. ns, not significant

Figure Lengend Snippet: FGL1-fc treatment counteracts cancer cachexia by alleviating body weight loss and WAT and muscle wasting. ( A ) Study design for the FGL1-fc treatment. ( B ) Tumor-free body weight% change of B16F10 tumor-bearing mice treated with vehicle and FGL1-fc ( n = 5 per group). ( C ) Measurement of the food intake (the food intake of mice is calculated as the average of a cage of 5 mice). ( D ) Fat percentage of mice ( n = 5 per group). ( E ) Lean mass percentage of mice ( n = 5 per group). ( F – I ) Representative anatomical image, weight, hematoxylin and eosin ( H & E ) staining and adipocyte size of eWAT ( n = 5 per group). ( J – M ) Representative anatomical image, weight, H&E staining and cross-section area of gastrocnemius muscles ( n = 5 per group). All values are presented as mean ± SEM. P values were determined by one-way ANOVA, with * p < 0.05, ** p < 0.01, and *** p < 0.001 indicating different levels of statistical significance compared with control. ns, not significant

Figure Lengend Snippet: FGL1-fc reverses lipid and muscle metabolism alterations in B16F10 cachectic mice. ( A ) Three pathways of fatty acid metabolism. ( B ) FGL1-fc counteracts a decline in the expression of fatty acid synthesis genes FAS and SCD1 ( n = 5 per group). ( C ) Both B16F10 tumor and FGL1-fc do not impact the gene expression of lipolysis ( n = 5 per group). ( D ) FGL1-fc does not counteract the decrease in the expression of fatty acid storage gene DGAT2 ( n = 5 per group). ( E ) Levels of HSL or p-HSL in eWAT ( n = 4 or 5 per group).
