Resumo do Projeto

Autophagy is a lysosomal-dependent degradative pathway that promotes recycling of cytoplasmic components, such as organelles and proteins, aiming at maintaining cellular homeostasis.
This process can be activated under different stressful situations, such as starvation, oxidative stress and DNA damage. Deficiencies in this pathway were associated to cardiopathies, cancer, neurodegeneration and aging. In this lab, we develop a project that aims at investigating autophagy in response to UV-induced lesions on the DNA in skin human fibroblasts, as well as the importance of this degradative pathway in glioma cells exposed to different chemotherapeutic agents.
