Mitochondria are key organelles involved in ATP production and regulation of several signaling cascades that ultimately affect cell death and survival. Mitochondrial dysfunction plays a critical role in the development and progression of cardiovascular diseases, such as myocardial infarction. Therefore, mitochondria have become an attractive therapeutic target for the treatment of cardiov…
4-hydroxy-2-nonenal (4-HNE) is a major by-product of lipid peroxidation, a process that is exacerbated under oxidative stress conditions. This aldehyde is highly reactive with proteins, lipids and DNA, causing target loss of function and degradation in most cases. For this reason, accumulation of 4-HNE has been correlated with the establishment and progression of many diseases, including …
Our current results demonstrate that intracellular protein quality control [machinery that detects, repairs and disposes cytotoxic proteins] is impaired during muscle dysfunction and wasting. We also show that pharmacological activation of β2-adrenoceptor induces an overall improvement of protein quality control-related mechanisms in skeletal muscle. Our next step is to establish a causal…

Heart failure (HF) is the leading cause of morbidity and mortality worldwide. Patients with HF are classified into two subgroups: HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). For decades, the majority all scientific attention was focused on the understanding of HFrEF due to of its practical diagnostic criteria and high prevalence of morbidity …
Mitochondria are organelles that continually undergo fusion and fission. These opposite processes work together to maintain the shape, size, number and function of mitochondria. Recently, our group demonstrated that reestablishing mitochondrial fusion-fission balance through exercise or drug therapy is sufficient to restore mitochondrial bioenergetics and improves the prognosis of heart f…
Heart failure is a degenerative syndrome that affects over 20 million people worldwide, being considered an important health public problem. Overall, 50% of heart failure patients die in the time-window of 5 years after diagnostics. Heart failure is classified into 2 classes: heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). H…

Currently affecting 8 million people, mainly in Latin America (endemic area), Chagas Disease (CD) is caused by the protozoan Tryoanosoma cruzi (T. cruzi). The 2 medicines (Benznidazole and Nifurtimox) avaliable to treat CD focus on killing the parasite and are partially effective only in the acute phase of the disease. Based on this, new targets and therapies are needed. It was recently d…
Sustained loss of skeletal muscle mass and function occurs mainly during degenerative processes. Increased proteolytic activity (i.e. autophagy) has been extensively associated with muscle atrophy. However, proteolysis is also crucial for the maintenance of cellular homeostasis. In fact, autophagy serves as a protective system against non-functional proteins/organelles through a sophistic…
Despite scientific and therapeutic advances, ischemic heart disease is still the leading cause of death worldwide. This pathology is caused by decreased blood flow (ischemia), which promotes tissue damage and cell death according to the intensity and time of ischemia, thus causing biochemical and functional changes to the myocardium. Among these changes, the increase in intracellular calc…

Geroscience has been successful in identifying evolutionarily conserved genes and molecular mechanisms capable of increasing longevity, mainly in the nematode Caenorhabditis elegans (C. elegans). However, it is still not clear whether this prolonged period of life is associated with improved healthspan (either relative or absolute). Healthspan is defined by the period of life in which an …
Doxorubicin is an anthracycline widely used to treat different types of cancer including leukemia, lymphomas and breast cancer. However, it has high risk of cardiotoxicity since it accumulates and negatively affects cardiac mitochondrial proteostasis and bioenergetics. Disruption of mitochondrial proteostasis triggers a conserved signaling pathway termed mitochondrial unfolded protein res…
The health benefits of exercise have long been recognized. The importance of autophagy for this process is now also well-established. New research suggests that significant benefits from exercise depend on selective degradation of defective mitochondria through mitophagy, but the mechanisms connecting these processes are unknown. This project aims to fill this critical gap in our knowledg…
