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. AS, Ascites; Ag, Antigen; OA, oleic acid; BMS, BMS309403. 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

Article Title: Potential involvement of peroxisome proliferator-activated receptors in the inhibition of mammary lipid synthesis during diet-induced milk fat depression

doi: 10.3168/jds.2024-25575

Figure Lengend Snippet: Effect of trans- 10, cis- 12 CLA and peroxisome proliferator-activated receptor gamma (PPAR-γ) agonist troglitazone (TG) and antagonist T0070907 (T07) on lipogenesis in a bovine mammary epithelial cell line (MAC-T). Lipogenesis was measured by incorporation of 14 C acetate into lipids during the last 4 h of treatment and expressed relative to the control. Cells were treated for 24 h in basal medium with 75 μ M trans- 10, cis- 12 CLA, 5 μ M TG, 5 μ M T07, or combinations of these treatments in the presence or absence of 10 μ M of 9- cis retinoic acid (9c RA). Values represent LSM ± SEM (includes intra- and interexperimental run error). Means are scaled relative to control (control set to 100; n = 6 wells per treatment across 2 independent experiments). Means that do not share a letter (a–d) differ ( P < 0.05).

Article Snippet: Treatments included 5 μM PPAR-γ agonist troglitazone (TG; Calbiochem, San Diego, CA), 5 μM PPAR-γ antagonist T0070907 (T07; Calbiochem, San Diego, CA), 10 μM cis-9 retinoic acid (9cRA; Sigma, St. Louis, MO), and 75 μM trans-10,cis-12 CLA, either individually or in combination.
