CELIS, Luis Gustavo et al. Lipolitic effect of Resveratrol in cells 3T3-L1. Salud, Barranquilla [online]. 2008, vol.24, n.2, pp.165-171. ISSN 0120-5552.

Introduction: The obesity it is one of the main risk factor for develop insulin resistance and type 2 diabetes, one component of calorie restriction in mammals it is given by Sirtuins proteins among them (SIRT 1), which have the capacity of inhibit the expression of the genes control by the nuclear receptor PPARγ, promoting the mobilization of the fatty acids from the adipocyte and avoiding their storage. Objective: The purpose of this work is to evaluate the capacity of Resveratrol (flavonoid found in grape skin) as a lipolytic agent on adipose cells differentiated by Rosiglitazone. Materials and methods: Fibroblast preadipocyte adipogenesis was carried out using Rosiglitazona, incubating murine 3T3-L1 cells in the presence of a differentiation cocktail of Rosiglitazone, Isobutil Xantine and Dexametasone, monitoring between days 0 to 10 of differentiation every two days. Subsequently doses of Resveratrol and Rosiglitazone were added to each cells culture and followed up until day 6, to make sure the Resveratrol effect. The triglycerides quantification was performed qualitatively by red oil stain and quantitatively by isopropanol extraction and absorbance measurement at 510 nm. Results and analysis: The results allowed us to see the Resveratrol lipolytic effect on the adipocyte cells, because the amount of triglycerides was lower than the cultures differentiated by Rosiglitazone. This could be caused by the Resveratrol capacity of stimulate the SIRT 1 activity, which also inhibit PPARγ. Conclusions: This kind of work will help in develop new interventions in the treatment of the obesity and complications.
