Scientific activity
Since 1989 she has been involved in CNR institutional research projects as well as in projects sponsored by the European Community and by public and private Italian Institutions (Ministry of Health, Ministry of Education, University and Research, Associazione Italiana per la Ricerca sul Cancro, Telethon and Cariplo Foundation).
She is interested in the study of inborn defects in transcription and/or DNA repair and their relationships with physical and mental development, cancer proneness and aging. In particular, she has experience in the genetic and molecular analysis of DNA repair processes in human cells and in the biochemical and molecular characterisation of patients with hereditary disorders defective in nucleotide excision repair (NER), namely trichothiodystrophy (TTD), xeroderma pigmentosum (XP) and Cockayne syndrome (CS). She has been involved in the definition of genotype-phenotype relationships in a large sample of patients affected by TTD, XP or CS and she demonstrated that instability of the repair/transcription factor TFIIH is a typical trait of TTD. Her present research interest is investigating the impact of NER alterations in different skin cell-types and during cell/tissue differentiation.
