Study Title | Possible PPARG-independent effects of DINCH and MINCH on central carbon metabolism |
Study Summary | In the third part of the project, we investigated the PPARG-independent effects of DINCH and MINCH on the central carbon metabolism of human SGBS cells. SGBS preadipocytes were treated for 12 days with 10 µM MINCH, 10 µM DINCH, or rosiglitazone in the presence of the PPARG inhibitor GW9662. Irreversible blocking of PPARG was achieved by incubating cells with 10 µM GW9662 1 hour before treatment and maintaining a regular treatment interval of 2 days. In conclusion, although the PPARG inhibitor GW9662 greatly reduced the effects of MINCH and rosiglitazone, slightly increased lipid accumulation along with increased lactate secretion and increased concentrations of pyruvate cycle metabolites were consistently induced by MINCH treatment even after PPARG inhibition. This suggests that MINCH exerts its effects on lipid accumulation and central carbon metabolism at least in part via a PPARG-independent mechanism. |

Project Title: | MINCH causes metabolic rewiring towards lipid accumulation and adipogenesis |
Project Summary: | Humans are ubiquitously exposed to plastic additives, including plasticizers. There is growing evidence that exposure to certain plasticizers is associated with the development of obesity due to their metabolism-disrupting properties. Following the restriction of the use of the phthalate plasticizer di-(2-ethylhexyl) phthalate (DEHP) due to its adverse health effects, it has been replaced by new substitutes such as the plasticizer diisononylcyclohexane-1,2-dicarboxylate (DINCH). Despite recent studies suggesting that the primary metabolite monoisononylcyclohexane-1,2-dicarboxylic acid ester (MINCH) promotes human adipocyte differentiation, the adipogenic properties of MINCH remain controversial. Because the metabolome largely reflects the molecular phenotype and is sensitive to perturbation by external factors, we used targeted metabolomics to investigate the effects of DINCH and MINCH on key metabolic pathways of adipocytes. Analysis of central carbon metabolism is particularly relevant because it provides cellular energy through the degradation of organic compounds and metabolic precursors for anabolic functions that are critical for adipocyte function, such as de novo lipogenesis. The project consists of three main studies: analysis of the effects of DINCH and MINCH on central carbon metabolism of human SGSB cells, analysis of the insulin response of DINCH- and MINCH-treated SGSB cells, and analysis of the effects of DINCH and MINCH on central carbon metabolism of human SGSB cells in the presence of the PPARG inhibitor GW9662. |
