A central problem of oncology is represented by the fact that the most molecularly targeted anticancer drugs produce only transient therapeutic effects due to the clonal selection of drug-resistant tumor cells.

Current studies

Our projects are oriented to the development of experimental models able to recapitulate in vitro and in vivo the complexity of the mechanisms underlying the process of tumor evolution and the development of drug resistance. By using a combination of biochemistry, molecular and cellular biology approaches as well as preclinical in vivo models, the current projects are aimed at gaining insight into the general mechanisms of cell transformation and to develop tumor-specific therapies based on "synthetic lethality".

One of the key hallmarks of cancer cells is sustained growth, which require a complex metabolic rewiring with an enhancement of anabolic pathways and a profound alteration of redox homeostasis. In particular, we focus on genetic and pharmacological approaches that modify the metabolic profile and redox homeostasis of cancer cells to trigger their response to pro-apoptotic stimuli.
