About the Project
Cancer is one of the leading causes of death world-wide therefore there is an urgent need for more fruitful treatments for cancer patients. At advanced stages of disease, conventional therapies are ineffective due to a small population of drug-resistant cells called cancer stem cells that can reform the tumour. Indeed, the spread of these cells to distant organs accounts for over 90% of patient deaths. Our aim is to discover how these resistant cells can be efficiently and permanently eliminated.
Thus, our research is focused on the novel regulatory mechanisms which govern the balance between stem cell maintenance and differentiation. Furthermore, by disentangling the heterogeneity within the tumour, we aim to identify the key players and properties that enable stem cells to cause cancer growth and spreading. We will also study the mechanisms involved in cell plasticity to understand how cancer cells respond to conventional therapies depending on their state. To this end, we will use mouse models, clinical association analyses, high-throughput approaches, next-generation sequencing, single cell technologies, patient-derived material and 3D organoids which very well models intra-tumour heterogeneity.
Our main goals are
• Characterize the cells that are resistant to current therapies.
• Force cancer cells to change their properties (lose their stemness becoming differentiated cells) so that they can no longer divide and reform a tumour.
• Understand the reversibility of the stemness process (as differentiated cells can also gain stem cell properties). It will help us to design trials to overcome resistance.
• Study how these resistant cells can be targeted by novel approaches or drug combinations.
By tackling the above-mentioned research goals, we hope to improve treatment of cancer by:
• Identifying patients that are likely to relapse and/or stop responding to the treatment.
• Reduce the number of possible therapeutic strategies.
• Design novel drug combinations to increase rates of response and cure through more precise use of cancer therapies.
• Improve patient’s survival.
Start dates are October, December, February and April each year.
