Objective:
To investigate the inhibitory effects of tetramethoxystilbene, a selective CYP1B1 inhibitor, on adipogenic differentiation of C3H10T1/2 multi-potent mesenchymal cells.
Methods:
In vitro cultured C3H10T1/2 cells at full confluence were induced by adipogenic agents (10 µg/ml insulin, 2 µmol/L dexamethasone and 0.5 mmol/L 3-isobutyl-1-methylxanthine) and exposed simultaneously to TMS at the final concentrations of 1.0, 2.0 or 4.0 µg/ml. Oil Red-O staining was used to observe the cell differentiation. The expression of peroxisome proliferator-activated receptor gamma (PPARγ) and its target genes cluster of differentiation 36 (CD36) and fatty acid binding protein 4 (FABP4) were quantified by real-time RT-PCR and Western blotting.
Results:
Oil Red-O staining and TG contents revealed that TMS suppressed induced differentiation of C3H10T1/2 cells. TMS exposure of the cells dose-dependently decreased both mRNA and protein expressions of PPARγ, a key nuclear transcription factor during adipogenesis, and also lowered the mRNA expressions of PPARγ target genes CD36 and FABP4.
Conclusion:
TMS can suppress adipogenic differentiation of C3H10T1/2 cells by inhibiting PPARγ
Insights
Tetramethoxystilbene (TMS) inhibits adipogenic differentiation in mesenchymal stem cells. This selective CYP1B1 inhibitor suppresses key adipogenesis markers, offering potential therapeutic strategies.
Area of Science:
- Cell Biology
- Biochemistry
- Pharmacology
Background:
- Adipogenesis, the process of fat cell differentiation, is a complex mechanism regulated by specific molecular pathways.
- Dysregulation of adipogenesis is implicated in metabolic disorders such as obesity and diabetes.
- Selective CYP1B1 inhibitors are being explored for their potential therapeutic applications.
Purpose of the Study:
- To investigate the inhibitory effects of tetramethoxystilbene (TMS), a selective CYP1B1 inhibitor, on the adipogenic differentiation of C3H10T1/2 multi-potent mesenchymal cells.
- To elucidate the molecular mechanisms underlying TMS's effect on adipogenesis.
Main Methods:
- C3H10T1/2 cells were induced to differentiate into adipocytes using standard adipogenic agents.
- Cells were treated with varying concentrations of TMS (1.0, 2.0, 4.0 µg/ml).
- Oil Red-O staining assessed lipid accumulation, while real-time RT-PCR and Western blotting quantified the expression of PPARγ, CD36, and FABP4.
Main Results:
- TMS significantly suppressed adipogenic differentiation in a dose-dependent manner, as evidenced by reduced lipid accumulation.
- Both mRNA and protein levels of peroxisome proliferator-activated receptor gamma (PPARγ), a critical transcription factor in adipogenesis, were decreased by TMS.
- Expression of PPARγ target genes, CD36 and FABP4, was also downregulated by TMS treatment.
Conclusions:
- Tetramethoxystilbene (TMS) effectively suppresses adipogenic differentiation of C3H10T1/2 cells.
- The mechanism involves the inhibition of PPARγ expression and its downstream target genes.
- TMS demonstrates potential as a therapeutic agent for conditions associated with aberrant adipogenesis.
