Genetic analysis of solid tumors and cancer modeling in Drosophila.

1) Genetic analysis of brain tumours. The study of genomic features in brain cancers should enable the discovery of characteristic gene-expression patterns that can be associated with functionally important states. Furthermore the understanding of the molecular abnormalities that cause this tumour are crucial for developing new strategies and approaches to treatment. The aim of our molecular studies on glioma is to capture a genetic portrait of this malignancy, in order to find out markers of tumour progression and of responsiveness/resistance to chemio- and radiotherapy.

2) Cancer modelling in Drosophila. Several aspects of human carcinogenesis can be profitably investigated using Drosophila as an in vivo model. Despite some obvious differences between flies and mammals, thanks to the high degree of conservation of most signaling pathways, analyses of the fly tumour suppressors have produced substantial contribution toward understanding the basic cell biology of tumourigenesis, in particular links between cell growth, cell proliferation and apoptosis. We induce genetic modifications in Drosophila epithelia generating clones of cells in which tumour suppressors and oncogenes are simultaneously mutated and investigate the mechanisms underlying malignant progression toward invasion and metastasis.
