The use of natural toxins to treat cancer is not a novel idea and some toxin-derived drugs like Paclitaxel are well established in the clinic and more drugs are in development. All these treatments are effective in controlling tumour cell growth, unfortunately, they have significant toxicity toward healthy cells. For decades, researchers all over the world had tried to find the “magic bullet” that can discriminate between cancerous and healthy cells to target these treatments specifically to cancer cells and reduce their toxicity.
All cells present on their surface proteins with sugar molecules attached to them and recently it has been found that cancer cells have different ways to attach these sugars. These differences have been already used in cancer diagnosis and prognosis, but they can also be used to specifically direct drugs toward cancer. Intriguingly, one powerful toxin produced by some strains of a Salmonella enterica uses some of the sugars to attach and penetrate the cells.
In this project, we will investigate the possibility to exploit the component of the salmonella toxin as a drug delivery system able to selectively target cancer cells by evaluating the toxicity of nTT toward a panel of tumour cell lines. We will also design different ways to attach a payload (drug, imaging moiety, theranostic agent) to the toxin component to specifically deliver them to cancer cells. Eventually, we will also engineer its sequence to improve specificity and selectivity towards tumour cells.
This is a cross-disciplinary project involving elements of molecular biology, drug discovery and organic chemistry. In this project, you will gain experience in wide range of techniques such as general microbiology, cell culture, molecular biology, protein expression and purification, fluorescent and confocal microscopy, flow cytometry techniques. You will also learn about bioconjugation chemistry and chemical characterization by LC-MS.
Informal enquiries are encouraged, please contact the lead supervisor Dr Massimiliano Baldassarre (Massimiliano.email@example.com) for further information.
Essential background of student:
Applicants should hold a 1st Class UK Honours degree (or international equivalent) in a relevant subject. Those with a 2:1 UK Honours degree (or international equivalent) may be considered, provided they have (or are expected to achieve) a Distinction or Commendation at Master’s level.
This project will be based within the Institute of Medical Sciences (IMS), part of the School of Medicine, Medical Sciences and Nutrition, at the University of Aberdeen. The IMS is located on the Foresterhill Health Campus, one of the largest clinical complexes in Europe, which also includes the Institute of Applied Health Sciences, the Rowett Institute, and a large teaching hospital.
