Figure Lengend Snippet: The enhanced APC function of B cells by OA in vitro is achieved through H3K27ac-mediated upregulation of PPAR γ expression. A Protein expression of β -actin and H3K27ac in 3 w OvCa-bearing mouse ascitic CD19 + B cells pretreated with BMS and treated with OA was assessed by WB. β -Actin was used as the internal control to calculate the relative expression level of H3K27ac. B The enrichment percentage of H3K27ac at the PPAR γ , CD80, CD86, and CD83 promoter regions was quantified using ChIP-seq analysis. C Correlation analysis of PPAR γ and APC function-related genes (CD80, CD86, CD83, MHC II) in B cells in OvCa patients in the TCGA database (n = 426). D Analysis of protein interaction among FABP4, PPAR γ , CD80, CD86, and CD83. E The enrichment percentage of PPAR γ at the CD80, CD86, and CD83 promoter regions was quantified using ChIP-seq analysis. F Mean fluorescence intensity of CD80, CD86, and CD83 in 3 w OvCa-bearing mouse ascitic CD19 + B cells pretreated with BMS, GW9662/Trog, and treated with OA was detected by flow cytometry.

Data are presented as the mean ± SD of three independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, ns, not significant

Article Snippet: In the mechanistic study, mouse ascitic CD19 + B cells (1 × 10 6 /ml) were pretreated with fatty acid binding protein 4 gene (FABP4) inhibitor (BMS309403, MedChemExpress; Cat# HY-101903; 50 μM), PPARγ antagonist (GW9662, MedChemExpress; Cat# HY-16578; 25 μM), and PPAR γ agonist (Troglitazone, Trog, MedChemExpress; Cat# HY-50935; 10 μM) for 2h, respectively.

Figure Lengend Snippet: The mechanism diagram of combining adoptive immunotherapy with APC-function-enhanced B cells and LDC improves anticancer immunity in metastatic OvCa mice. In vitro, OA enhances the expression of CD80/CD86/CD83 of B cells through the H3K27ac-mediated upregulation of PPAR γ expression. Then, the B cells are adoptively transferred into the abdominal cavity of metastatic OvCa mice. In the abdominal cavity, LDC facilitates the APC function of the transferred B cells by causing apoptosis of cancer cells. The transferred B cells promote the activation, proliferation, and differentiation of T cells, which release higher levels of effector molecules (IL-2, GZMB, and IFN- γ , etc.), and facilitate the formation of lymphoid aggregates, finally improving anticancer immunity. LDC, low-dose chemotherapy

Figure Lengend Snippet: The measurement of p-STAT3, STAT3, and PPARγ through western blot analysis (n = 6). All data are expressed as means ± standard error of the mean (SEM). Statistical significance was determined in comparison to the model group, with thresholds set at * p < 0.05, ** p < 0.01, and *** p < 0.001.
