GCDC Project-led Studentship - School of Physical Sciences & School of Biosciences: Identification of the cellular targets of the Malaysian phytochemical pentamethoxyflavone, a candidate agent for the chemoprevention of colorectal cancer
School of Physical Sciences and School of Biosciences, University of Kent, Canterbury, with placements at Universiti Malaysia Sarawak, Malaysia
The incidence of colorectal cancer (CRC) has risen at an alarming rate in Malaysia, becoming the second most common cancer in males and third most common in females. Other southeast Asian Lower and Middle Income Countries (LMICs) show a similar profile, and CRC is now an area of unmet medical need in the region.
Our collaborator in Malaysia, Dr Isabel Lim Fong (Universiti Malaysia Sarawak), has discovered that pentamethoxyflavone (PMF), a compound isolated from the common Malaysian plant Orange Jasmine (Murraya paniculata), can kill both precancerous and cancerous colon cells in vitro. It will also prevent progression of colon polyps into CRC in vivo, an effect known as cancer chemoprevention. The cellular target(s) of this chemoprevention activity are unknown, and their identification is critical as it will allow the generation of a more potent and selective PMF-like molecule with optimised drug-like properties ready for clinical trial.
The aim of this project to identify the cellular targets of PMF that drive cancer chemoprevention. To achieve this a tagged version of PMF will be generated to pull out and identify proteins from cells that bind to this compound. This is a proof-of concept project to be repeated in the future with other plant extract-derived compounds in Malaysia that target cancer and other non-communicable diseases.
This project is part of the University of Kent’s Global Challenges Doctoral Centre (GCDC), established to enable UK researchers to collaborate with those in LMICs to address their development needs. As well as the primary scientific project, the student will receive interdisciplinary GCDC training, and undertake trips to Malaysia to work with collaborators.
- Tag PMF with biotin and covalent modifiers in various positions through chemical synthesis, and then use cellular assays to identify which has the activity most similar to PMF itself.
- Perform pull-down studies on the lysates of precancerous and cancer colon cells to separate the proteins bound by PMF. The proteins will then be identified by mass spectrometry.
- Cellular studies to determine whether loss of function of each protein target in cells recapitulates the PMF cancer chemoprevention phenotype.
This project will be jointly supervised by:
Prof Michelle Garrett
(Kent Biosciences) who has a leading record in cancer therapeutics
Dr Christopher Serpell
(Kent Physical Sciences) who is an expert in chemical manipulation of biomolecules
Dr Isabel Fong Lim
(Universiti Malaysia Sarawak), remotely, who is the global leader in PMF studies
They will provide a rich interdisciplinary research environment, and the student will be integrated into both the Garrett and Serpell groups, as well as making trips to Dr Fong in Malaysia for training.
