Abstract:
AIM To investigate the impact of varying dosages of Supplemented Wendan Decoction on the PI3K/Akt/FOXO1 glycolipid metabolic pathway in 3T3-L1 adipocytes.METHODS The CCK-8 assay was used to determine the concentration of Supplemented Wendan Decoction-medicated serum.The mature adipocytes differentiated from 3T3-L1 preadipocytes after induction were further divided into the blank control group,the model group,the rosiglitazone group(10 mg/L),and the Supplemented Wendan Decoction groups(5%,10%,and 20%),followed by the sample collections after 48 hours of treatment.Oil red O staining quantified lipid accumulation in 3T3-L1 adipocytes;extracellular glucose levels were measured using glucose oxidase(GOD)assay;RT-qPCR analyzed mRNA expressions of IRS-1,PI3K,Akt,GLUT4,IL-6,TNF-α and IL-1β;Western blot assessed protein expressions of INSR,IRS-1,PI3K-p85,Akt,FOXO1 and GLUT4.RESULTS No significant changes in cell viability(P>0.05)were observed in 3T3-L1 preadipocytes exposed to serum containing supplemented Wendan Decoction at different concentrations for 24,48,or 72 hours.The 3T3-L1 preadipocytes held the capacity to differentiate into mature adipocytes within a 14-day induction period.Compared to the model group,all supplemented Wendan Decoction groups exhibited reduced lipid accumulation in adipocytes and downregulated mRNA expression of IRS-1,IL-6,TNF-α and IL-1β(P<0.01);the low-dose group demonstrated increased mRNA expressions of PI3K and GLUT4(P<0.05,P<0.01),alongside elevated protein expressions of INSR,IRS-1,PI3K-p85,Akt and GLUT4(P<0.05,P<0.01);the medium-dose group showed enhanced GLUT4 mRNA expression,and upregulated protein expressions of INSR and FOXO1(P<0.01).After 24 hours intervention,the high-dose Supplemented Wendan Decoction group exhibited increased glucose consumption in adipocytes(P<0.01),and elevated protein expression of INSR,Akt and FOXO1(P<0.05,P<0.01).CONCLUSION Supplemented Wendan Decoction reduces lipid accumulation in adipocytes,regulates glucose and lipid metabolism,and promotes metabolic homeostasis through PI3K/Akt/FOXO1 signaling pathway.
