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.
