Current objectives of the research in my group are the investigation of transcriptional and epigenetic mechanisms in human cancers and the development of innovative therapeutic strategies. Transcription factors are central nodes in multiple oncogenic pathways and represent attractive targets for development of new cancer therapeutics. However, very few direct pharmacological inhibitors of transcription factors are currently available. My group is investigating various approaches, including small molecule inhibitors, small interfering RNAs and oligonucleotides, to block the activity of oncogenic transcription factors. Furthermore, extensive modifications of the epigenetic landscape occur along with deregulated activity of transcription factors and are at the basis of the phenotypic reprogramming associated with tumor development, progression and treatment resistance. We are investigating the role of epigenetic regulators in tumor progression and treatment resistance and the impact of specific inhibitors on these processes. Novel epigenetic effectors, such as promoter-associated long noncoding RNAs, microRNAs and RNA binding proteins, are also investigated as potential targets for innovative therapeutic strategies. Ultimately, stem-like tumor cells in human tumors are emerging as important players in tumor progression, metastasis and treatment failure. It is therefore becoming apparent that it is necessary to block the cancer stem-like cell subpopulation in order to have an effective and lasting impact of the disease. With this intent we are exploring the biological pathways responsible for self-renewal, expansion and maintenance of stem-like tumor cells in human cancers. A major focus is on the processes that underlie the epigenetic and metabolic reprogramming and sustain the stem-like phenotype. In collaboration with the prostate cancer biology group at the IOR, we have established protocols and experimental models to study cancer cells with stem-like features in vitro and in vivo. These systems are used to study the specific features of cancer stem cells and test inhibitors of key pathways to establish their potential for therapeutic applications.
