Results in brief
Targeting microRNAs for ColoRectal Cancer Therapy
The work carried out during my Career Integration Grant involved the analysis of microRNA deregulation in colorectal cancer and the discovery of novel methods to target microRNA deregulation. We screened and analysed microRNA expression in primary and metastatic colorectal cancer cases collected as part of clinical trials as well as publically available databases. We published data highlighting the contribution of some of these microRNAs in colorectal cancer initiation and progression and their potential predictive and prognostic role. More recently we ran high-throughput siRNA and drug screenings to define vulnerabilities and mechanisms of resistance associated with microRNA deregulation. We validated hits from our screenings in vitro and in vivo by using colorectal cancer patients’ material. We also identified microRNAs promoting cancer phenotype downstream of oncogenic pathways such as KRAS, TP53 and PTEN. We studied the contribution of these microRNAs in controlling cell adhesion, metabolism and angiogenesis. The definition of molecular mechanisms of drug sensitivity or resistance associated with microRNA deregulation may help to tailor cancer treatment by defining novel therapeutic strategies and implementing patient’s stratification in prospective studies. The Career Integration Grant contributed toward the set-up of my own research group and allowed me to generate preliminary data that proved to be critical in getting further internal (Institute of Cancer Research London) and external research funding from cancer charities (Cancer Research UK) and the National Health System through the National Institute for Health Research in England. The Career Integration Grant also contributed to transfer my knowledge and my skills in the area of microRNAs to other fields of application and other institutions in Europe as supported by a number of novel collaborations with Institutions in Italy and Sweden. These collaborations involve the use of microRNAs as predictive/prognostic biomarkers in cancer and internal medicine. The award of the Career Integration Grant represented a crucial step in my re-integration in Europe as it provided me with research funding when I needed it most and also because it represented an important credential to secure additional financial support and a long term position in one of the top ranking research institutions in Europe facilitating my transition to a permanent position as a clinician/scientist.

Project objective
MicroRNAs are small non-coding RNAs involved in cell homeostasis and carcinogenesis. MicroRNA deregulation is associated with colorectal cancer (CRC) progression. My study proposes to identify genetic and epigenetic events leading to microRNAs deregulation and use them as targets for drug development. My research proposal will address two important questions. First it will assess the contribution of genetic and epigenetic events in controlling microRNA genes and cancer phenotype. Second it will define synthetic lethal interaction between microRNA genes aberration and kinase genes in order to define novel target for therapy.Mutations and promoter methylation of microRNA genes and microRNA processing genes will be analyzed by massive parallel sequencing in a first cohort of CRC. Mathematical and in vitro analysis will be performed to test whether a mutation is a driver or passenger one. The frequency of driver mutations and promoter methylation will be confirmed in a large case-control study encompassing 2500 CRC patients. Mutational and methylation status will be matched with clinical-pathological features in order to detect correlations with clinical outcome. In order to translate my findings into drug development, genetic aberration in microRNA genes will be reproduced in CRC cell lines. Isogenic cell lines harboring the wild type or the mutant allele will be tested for cell viability in a parallel RNAi screening using siRNA libraries targeting kinase. Protein kinases are important mediators of microRNA function. More importantly, catalytic inhibitors of kinase can be easily developed making them attractive targets for synthetic lethality screening and drug development.
