It has been shown previously that microtubules, which act like scaffolding within a cell, can influence how tumour cells respond to paclitaxel chemotherapy. Professor Ahmed’s team has been looking at how microtubules are involved in resistance to paclitaxel. Their goal has been to improve the effectiveness of paclitaxel by including other drugs that make cancer cells more susceptible to damage done by this type of chemotherapy.
The team has shown, using cell lines in the laboratory, how an enzyme called FER regulates the stability of microtubules in ovarian cancer cells. They have also shown that tumour cells can become more sensitive to paclitaxel when FER is prevented from working properly, by removing it or targeting it with a specific small molecule. These results are an important achievement, which could be translated to patients to develop more effective therapies.
Professor Ahmed said, “These results provide strong evidence that by targeting FER we can improve the effectiveness of paclitaxel in killing tumour cells. The small molecules that target FER could potentially be developed into new drugs for ovarian cancer, to enhance the effectiveness of paclitaxel treatment.”
Chief Executive of Target Ovarian Cancer, Annwen Jones, said, “We are delighted to see the results of this important project. Through our research, we seek to optimise existing treatments and develop more effective treatments for ovarian cancer, leading to improvements in overall survival. Groundbreaking research such as this is only possible thanks to the generous funding we receive from individuals, trusts and legacies. In order to improve the long-term survival of women with ovarian cancer, we desperately need to provide more support for medical research such as this.”
