Study Title	Short-term metabolic insulin response of DINCH- and MINCH-treated cells
Study Summary	In the second part of the project, we examined the short-term metabolic insulin response of DINAH- and MINCH-treated cells and compared them with rosiglitazone-differentiated cells. For this purpose, the human SGBS preadipocyte cell line was exposed to differentiation media conditioned with DINCH (10 nM or 10 µM), MINCH (10 nM or 10 µM), or rosiglitazone, and the insulin response was measured by analyzing the changes in glycolysis and PPP between insulin-stimulated and non-insulin-stimulated cells. In conclusion, the insulin response of glycolysis and PPP of cells treated with 10 µM MINCH, but not with 10 nM MINCH or DINCH, was similar to cells differentiated with rosiglitazone.

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of the use of the phthalate plasticizer di-(2-ethylhexyl) phthalate (DEHP) due to its adverse health effects, it has been replaced by new substitutes such as the plasticizer diisononylcyclohexane-1,2-dicarboxylate (DINCH).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.

Collection:

Collection ID:	CO003025
Collection Summary:	The SGBS cells were obtained from Prof. Martin Wabitsch laboratory at the University Clinic Ulm. SGBS preadipocytes were differentiated according to the standard protocol described previously (Wabitsch et al., 2001).
Sample Type:	Adipose tissue
Storage Conditions:	-80℃

Treatment:

Treatment ID:	TR003041
Treatment Summary:	SGSB preadipocytes were maintained at 37°C and 5% CO2 in 95% humidity. To examine the insulin response of SGBS treated with DINCH and MINCH, SGBS preadipocytes were treated for 18 days with differentiation media without the PPARG agonist rosiglitazone supplemented with DINCH or MINCH (10 nM and 10 µM). To obtain an adipogenesis reference, SGBS cells were differentiated with rosiglitazone for 18 days according to the standard differentiation protocol. After replacing the medium on day 17 with differentiation medium without insulin and overnight incubation (insulin starvation), cells were starved for 1 hour with differentiation medium without glucose and insulin (glucose + insulin starvation). Subsequently, cells were incubated with either differentiation medium with insulin (insulin-stimulated cells correspond to plus-insulin samples) or without insulin (unstimulated cells correspond to minus-insulin samples). During differentiation, a final concentration of 0.01% (v/v) MeOH and 0.02% (v/v) DMSO was added to all differentiation media. Continuous exposure was mimicked by replacing the cell culture medium every other day. Each treatment was performed in five biological replicates (n=5).

Sample Preparation:

Sampleprep ID:	SP003038
Sampleprep Summary:	Extraction of intracellular and extracellular metabolites was performed by a 1:1:1 methanol:water:chloroform extraction protocol. For the extraction of intracellular metabolites, the culture medium was removed and the cells were rinsed twice with 1 ml of 0.9% ice-cold NaCl. The rinsing solution was removed, and the metabolism of the cells was stopped by adding 400 µL of MeOH (-20 °C) followed by 400 µL of ice-cold H2O containing 10 µM d6-glutarate. Cells were collected using a cell lifter and 400 µL of chloroform was added. After shaking at 1,400 rpm and 4 °C for 20 min, the extraction mixture was centrifuged at 18,000 g and 4 °C for 5 min. Subsequently, 300 µL volume of the polar upper phase was collected and evaporated to complete dryness. For the extraction of extracellular metabolites, 300 µL of the supernatant was extracted by adding 400 µL MeOH (-20 °C) containing 100 nM MEHP, 100 µL ice-cold H2O containing 40 µM d6-glutarate, and 400 µL chloroform (-20 °C). Subsequent sample preparation was identical to the extraction of intracellular metabolites. Note: After measurement of the samples by LC-MS, the raw AUC values uploaded here were normalized to the internal standard (d6-glutarate, if applicable) and DNA content per well (measured by DAPI fluorescence). After normalization, log2 fold changes were calculated by dividing the normalized peak area from each replicate of each treatment by the normalized peak area from each control. Insulin data were not normalized to DAPI because fold changes were calculated by dividing the intensities of the insulin-stimulated cells by the noninsulin-stimulated cells from each treatment.
