Project description
Combating mechanical resistance in pancreatic cancer
As tumours grow, they generate mechanical stresses due to increased cell proliferation and extracellular matrix remodelling. This results in increased pressure within the tumour and blood vessel constriction, impairing perfusion and drug delivery. Losartan, an anti-hypertensive drug, can alleviate vessel compression and improve chemotherapy response in pancreatic cancer patients. However, mechanical stresses can also induce chemotherapy resistance, compromising therapeutic outcomes. The ERC-funded MechanoResistance project aims to address chemotherapy resistance caused by mechanical constriction. Researchers will employ pancreatic cancer models to investigate the underlying mechanisms using cutting-edge bioengineering and biology techniques. Following validation of these findings in human tumour biopsies, innovative inhibitors will be tested in combination with losartan and immunotherapy as an improved anti-cancer strategy.
Objective
Cancer progression is closely associated with generation of mechanical stresses that cause the compression of tumor vessels, drastically reducing delivery of drugs. My co-workers and I found that host cells and extracellular matrix in tumors generate these stresses. Furthermore, we identified the anti-hypertensive losartan to alleviate intratumoral stresses and decompress vessels, allowing drugs to enter the tumor. My colleagues tested losartan in pancreatic cancer patients and found improved responses to chemo-radiation. Nonetheless, losartan cannot alleviate all stresses, and my preliminary data indicate that they induce chemotherapy resistance (“mechanoresistance”). Thus, even though vessel decompression facilitates drugs entering the tumor, mechanoresistance renders cancer cells insensitive to drugs. Alleviating mechanoresistance is an urgent clinical need, but this mechanism has not been well studied and strategies to overcome it have not been developed successfully. To address this challenge, I will employ a mixture of cutting-edge bioengineering and biology methods to identify the intracellular mechanisms that promote mechanoresistance, using in vitro and mouse models of pancreatic cancer. I will then employ inhibitors/drugs of the identified mechanisms to overcome mechanoresistance in vitro and in vivo to determine if they increase the efficacy of chemotherapy. I will also confirm whether these drugs work more effectively with losartan or alone. Using the best performing regimen, I will assess the immunological effects and efficacy in combination with immunotherapy, which has yet to induce a benefit in pancreatic cancer trials. In parallel, in order to take this ground-breaking goal of improving pancreatic cancer therapy to the clinic, I will examine the existence of the same mechanoresistance mechanisms in human tumors. The project will introduce novel, patient-specific, therapeutic strategies to directly boost clinical trials in pancreatic cancer patients.
