Análise integrada de sinais biológicos envolvidos na regulação bioenergética e controle de qualidade celular em doenças degenerativas.



The paradigm of mitochondrial biology has been dramatically changed over the last years. Besides their ability in generating ATP, mitochondria have been recently classified as key intracellular sensors, integrators and effectors; therefore playing a critical role in cellular homeostasis. Our lab has been working during the last years in deciphering the mitochondrial “node” function as well as its contribution to cellular biology. The main focus of our lab is to understand the role of mitochondria in integrating intracellular signals that affect function, morphology and life/death decisions of somatic cells (especially those long-lived differentiated cells such as cardiac myocytes) under health and disease conditions. We use different molecular, biochemical and physiological approaches to discover and validate new mitochondrial-related targets that affect cardiac biology. We also generate/screen new molecules capable of modulating mitochondrial “node” function with further application in therapeutics. Our lab has already worked on three molecules that affect mitochondrial “node” function, which might be used in the future to treat cardiac ischemia injury and heart failure (ongoing studies). Finally, our lab is currently interested in better understanding how mitochondrial quality control mechanisms (including mitochondrial retrograde signaling, aldehydic metabolism, protein turnover, dynamics and clearance) affect the biology of cardiac cells (including cardiac myocytes, fibroblast and mast cells) as well as progenitor cell fate decisions (stemness-and-differentiation decision). These studies will help us to develop more powerful and selective molecules to treat cardiac diseases.
