Background and Aim: Non-alcoholic fatty liver disease, characterized by abnormal fat accumulation in the liver, is associated with obesity and insulin resistance. Vaspin is an adipokine secreted by adipose tissue, and its gene expression increases when insulin sensitivity is reduced. In this study, we made a comparison between 3D and 2D cultures in regard to the effects of vaspin on fatty acid metabolism.
Materials and Methods: The steatosis model was induced by oleic and palmitic acid in HepG2 cell line in two- and three-dimensional cultures (collagen gel). Then, the cells were treated with 100 ng/ml vaspin for 24 hours. We used Real time PCR for measurement of the expressions of FABP4, MCAD, FAS and ApoB100 genes.
Results: In two- and three-dimensional cultures, we found significant decrease in the expression of FABP4 and FAS genes. There was no significant difference between the expression of these genes in the two- and three-dimensional cultures. We detected significant increase in the expression of MCAD and ApoB100 genes in 2D and 3D cultures. We did not find any significant difference in the expressions of MCAD and ApoB100 genes between two- and three-dimensional cultures.
Conclusion: Alteration of the expressions of the genes involved in uptake, lipogenesis, oxidation and secretion of fatty acids occurred in the group treated with vaspin compared to the control group in the 2-D and 3-D cultures. But, we did not find any significant difference in the expressions of these genes between the 2-D and 3-D cultures. |
