A new regulatory mechanism of response to metabolic stress

The Chromatin Biology group aims to define the mechanisms involved in the cellular response to different types of stress such as metabolic, oxidative and genotoxic stress. In particular, they focus on the impact of a family of enzymes, Sirtuins (responsible for the cellular stress response) in the maintenance of genome stability under these conditions and their impact in aging and different types of cancers, with a special focus on hematologic malignancies.

Dr. Vaquero’s group has just published an article in Science Advances journal in which they have identified and characterized enzymatic activity of Sirtuin SIRT7 that provides new evidence to understanding its regulatory capacity in the cellular response to different types of stress which damages cellular integrity.

The regulation of this response acquires special relevance since these types of stresses can produce alterations in the DNA and instability at the cell’s energy flow, and are directly involved in the appearance of pathologies such as cancer, neurodegenerative diseases, or a number of endocrine pathologies.
