The research activity of Dr. Moretti is mainly within the oncology field. Her interest is.related to the mechanisms that regulate cell response to stress signals, mostly those derived from DNA damage. Furthermore, the involvement of hormones in these processes is being investigated. Recent research has demonstrated the role of the MDM proteins, MDM2 and MDM4 in the growth arrest and apoptotic responses and in the regulation of the oncosuppressor p53 activity in normal and tumor cells. MDM4/MDM2 heterodimer exerts a relevant role of in the regulation of p53 function, especially in the control of its protein levels. Upon stress conditions raised by chemo- and radiotherapeutic drugs, the levels of the two regulators change substantially, the function of the heterodimer is redirected towards other targets, and the oncosuppressive activity of p53 is displayed. As part of this project, it has developed a patent (RM2012A000060 – EU 1408/2639240) about a peptide able to disrupt the heterodimer and activate p53. The project currently granted by AIRC aims to increase the knowledge about the peptide activity and to improve its pharmacodynamics properties in order to evaluate the efficiency and feasibility of its application.
More recently, this research conducted in collaboration with Dr. Rossella Lucà has allowed us to define the important role of MDM4 in the development of chemotherapy resistance and metastasis formation in ovarian cancer.
A second project aims to understand the role of steroid receptor as a disease modifier in the facioscapulohumeral dystrophy (FSHD), in order to define the potential application of estrogens to slow down the clinical course of the disease.
