Overview

Adult tissue homeostasis is maintained by the accurate integration of the different signaling pathways required to preserve cell identity. Stem cell maintenance and cell lineage determination are regulated by the coordinated activity of specific signaling pathways that converge on chromatin to activate and repress well-defined transcriptional programs. By shaping the epigenomic landscape of cells, transcription factors and chromatin modifying complexes orchestrate these processes. During tumor formation driver oncogenic mutations lead to the emergence of a progenitor-like state characterized by a change in cell identity and an extensive transcriptional reprograming. This reprograming is the result of widespread rearrangement in the repertoire of active functional elements, due to alterations at different levels in their regulation: mutation in their sequence, in the expression of different transcription factors, or aberrant activity of chromatin modifying enzymes, often mutated in cancer.

In our laboratory we investigate how external and internal stimuli are integrated at the chromatin level. In particular, by using a comprehensive approach, we aim to describe the role of chromatin modifying enzymes and transcription factors in the maintenance of adult stem cells and in doing so characterize the transcriptional mechanisms and the chromatin associated events involved in tumor formation and metastatic progression. Through the extensive characterization of these mechanisms our ultimate goal is the identification of putative targets for novel pharmacological approaches. Stem cells epigenetics

Research Projects

  • Understand the transcriptional and epigenetic events driving non-alcoholic fatty liver disease (NAFLD) and liver cancer formation and progression.
  • Characterize the transcriptional mechanisms and chromatin modifying enzymes required to maintain intestinal stem cell identity.
  • Characterize the transcriptional and epigenetic mechanisms required for the growth of hepatic metastasis from colorectal cancer.
  • Exploit patients-derived tumor organoids as models for pre-clinical studies.
