ID Bioinformatics Resources six.8 database (http://david.ncifcrf.gov/home.jsp (accessed on 19 August 2021)) [49]. The false discovery rate (FDR) error control method (FDR 0.05) was utilised to correct the p-value. Ultimately, a threshold value of p 0.05 was set and signaling pathways had been obtained. The KEGG pathway enrichment analysis final results had been visualized utilizing ImageGP (EHBIO Gene Technology, Beijing, China) (http://ehbio/ImageGP (accessed on 19 August 2021)). two.1.5. Construction and Analysis of Compound arget athway (C ) Networks The targets linked with this pathway were obtained in the KEGG pathway enrichment evaluation. Cytoscape (3.eight.2) (NRNB, Bethesda, MD, USA) was made use of to visualize and analyze the C network. 2.two. Cell Culture and Adipogenic Differentiation The mouse preadipocyte cell line (3T3-L1) was obtained from the American Kind Culture Collection (Manassas, VA, USA) and grown in Dulbecco’s modified Eagle’s medium (DMEM; Cellgro, Manassas, VA, USA) containing 10 bovine calf serum (BCS; Gaithersburg, MD, USA) and 1 penicillin/streptomycin antibiotics (P/S; Gaithersburg, MD, USA). To induce adipogenesis, 3T3-L1 preadipocytes (four 104 cells/well)Biomolecules 2021, 11,4 ofwere grown within a 24-well plate for 2 days, then the culture medium was replaced together with the adipogenic differentiation medium containing 0.four /mL dexamethasone (SigmaAldrich, St. Louis, MO, USA), 10 fetal bovine serum (FBS; Gaithersburg, MD, USA), 1-methyl-3-isobutylxanthine (IBMX; Sigma-Aldrich, St. Louis, MO, USA), 1 P/S antibiotics, and 5 /mL insulin (Sigma-Aldrich, St. Louis, MO, USA). Right after incubation for two days, the culture medium was replaced with DMEM supplemented with ten FBS, 5 /mL insulin, and 1 P/S antibiotics each 2 days. Ultimately, the culture medium was replaced with DMEM containing ten FBS and 1 P/S antibiotics, which was changed each two days, as previously described [50]. Hispidulin (5, ten, 20, and 40 ) and p-synephrine (five, 10, 20, and 40 ) had been added individually or in mixture within the culture medium for the duration of adipogenic differentiation. Hispidulin (98 ) and p-synephrine (98 ) had been purchased from Sigma-Aldrich (St. Louis, MO, USA). 2.three. Measurement of Cell Viability The viability of 3T3-L1 preadipocytes was assessed utilizing a tetrazolium salt (WST-1)-based colorimetric assay kit (Ez-Cytox Cell Viability Assay Kit; Daeil Lab Service, Seoul, Korea). The 3T3-L1 preadipocytes (4 104 cells/well, 96-well plate) had been grown in ten BCS and 1 P/S antibiotics for 24 h, after which treated with hispidulin (5, ten, 20, and 40 ) and p-synephrine (5, 10, 20, and 40 ) individually or in mixture. Right after therapy for 24 h, EZ-Cytox reagent was added, plus the 3T3-L1 preadipocytes had been additional incubated for 40 min. The spectrophotometric absorbance was measured working with a PowerWave XS microplate reader (CB1 Activator site BioTek Instruments, Winooski, VT, USA) at 490 nm, as previously described [51]. two.4. Oil Red O Staining On day eight, differentiated cells had been fixed with 4 paraformaldehyde resolution (SigmaAldrich, St. Louis, MO, USA) for 1 h and stained with Oil Red O solution containing 0.5 Oil Red O (ORO; Sigma-Aldrich, St. Louis, MO, USA), 40 distilled water (DW), and 60 isopropanol (Sigma-Aldrich, St. Louis, MO, USA) for 1 h. Soon after washing with DW, lipid droplets stained with ORO were BRPF2 Inhibitor Gene ID imaged below an inverted microscope at 20magnification and eluted with 100 isopropanol. The spectrophotometric absorbance was measured on a PowerWave XS microplate reader at 540 nm, as pre
