The Stress Study Laboratory (LABEEST) studies the stress response by quantifying stress markers as well as their effect on cardiac and metabolic responses in animal models.
We have focused on the role of plasma lipoprotein metabolism and associated proteins particularly relevant for the development of atherosclerosis, diabetes and obesity. Hormonal, nutritional and pharmacological regulation of key proteins involved in the metabolism of plasma lipoproteins are investigated with the goal of elucidating molecular mechanisms and putative therapeutic targets for cardio-metabolic disturbances. Scientific contributions have been made concerning the understanding of CETP (cholesteryl ester transfer protein) gene expression and its effects regarding atherosclerosis susceptibility and possible new functions of this protein (Oliveira HCF, Raposo HF. Adv Exp Med Biol. 2020). Together with Anibal Vercesi group, we have demonstrated that mitochondrial bioenergetic function and redox state alterations are present in hyperlipidemic states that predispose to atherosclerosis (Oliveira HCF, Vercesi AE.Mol Aspects Med. 2020)
