Recent statistics show that 1:2 people in the UK will develop cancer during their life. Of particular interest are new therapeutics that potentially allow a specific focus on tumours that are aggressive, metastatic and associated with poor prognosis.
A PhD student at N.U. is synthesising metal chelators that protect neurons against oxidative damage. These compounds have molecular features that enable them to cross the blood brain barrier by making them substrates of LAT-1. The compounds contain powerful Fe3+ chelator groups, hydroxypyridinones.
Metal chelators are known to be promising therapeutic agents against some forms of cancer (disruption of metal homeostasis, disruption of ROS formation, iron deprivation). Non-targeted chelators of the hydroxypyridinone family are known to have anti-cancer properties. Moreover, LAT-1 is over-expressed in some forms of cancer. We hypothesise that our compounds could preferentially target these cancer cells, inhibit their proliferation and promote cell death. Our compounds are available (more are being made) and ready for screening against cancer cell lines. Strikingly, LAT-1 status is considered a novel biomarker for high grade malignancy in prostate cancer and preliminary data within our group using prostate cancer cell lines show a differential sensitivity between PC3 (more aggressive) and DU145 cells thus demonstrating an effect of these compounds on cell survival and death.
The first aim of this project will be to high throughput screen for cytotoxicity across a range of well characterised sets of cells derived from normal and cancerous cells. We will stratify according to LAT-1 status as well as confirm the mode of entry and mechanism of action of these drugs The second aim will be to screen other cell behaviours that alter in cancer progression. For example, we will use a combination of end point assays (eg. clonogenic, comet and caspase) with sophisticated and established kinetic real time analysis, xcelligence.
