Researchers from the University of Liverpool have created a biomedical compound that has the potential to stop the spread of breast cancer. A recently published paper details these early findings.
Scientists from the Chemistry and Biochemistry Departments at the University of Liverpool and Nanjing Medical School in China have discovered a possible way to block proteins produced in the body when a patient has cancer and which causes its spread to other parts of the body. This process, called metastasis, is largely responsible for patient deaths.
The major problem hindering the successful treatment of commonly occurring cancers is not the primary tumour which can usually be removed by surgery, but its spread to other organs of the body.
Prof Philip Rudland, Emeritus Professor in the University of Liverpool’s Department of Biochemistry, explained: “As a general rule, cancer that has spread is treated with chemotherapy, but this treatment can rarely be given without severely harming or becoming toxic to the patient. The importance of our work was to identify a specific and important target to attack, without toxic side effects.”
The University’s research team have in the past discovered that specific proteins are involved in the metastatic process; these proteins are different from those involved in the production of the primary tumour. One such example is a protein called ‘S100A4’, and is the protein chosen by the research team to target for the identification of chemical inhibitors of metastasis, using model systems of cells from the highly metastatic and incurable hormone receptor-free breast cancer.
Dr Gemma Nixon, Senior Lecturer in Medicinal Chemistry at the University of Liverpool said: “This is an exciting breakthrough in our research. We now hope to take the next steps, and repeat this study in a large group of animals with similar metastatic cancers so that the efficacy and stability of the compounds can be thoroughly investigated and if necessary improved by further design and syntheses, prior to any clinical trials.”
“Significantly, this particular protein we’re investigating occurs in many different cancers, which could mean this approach may be valid for many other commonly occurring human cancers.”
