Cancer Biology Unit

The Cancer Biology unit within the Division of Cancer & Stem Cells is a multi-disciplinary research centre working on biological basic of cancer, and how we can use this to translate new findings on mechanisms and cancer processes into novel therapeutic approaches for cancer and other diseases.

We are funded by medical and cancer research charities, research councils and industry and have an active and lively basic and clinical scientific training programme at undergraduate and postgraduate levels.

Research issues

The research in the unit spans basic biology to clinical research focusing on translating new findings to clinical treatments, and involves strong collaborations with clinicians and industry.

Current research areas include imaging of key biological parameters within tumours, mechanisms of cancer growth, apoptosis, angiogenesis and metastatic pathways and stem cell evolution.

This includes in vivo and ex vivo modeling of the tumour microenvironment including: the process of epithelial-mesenchymal transition; analysis of paracrine interactions in tumour progression including HGF/c-met, Hedgehog, Gastrin, Vascular and Fibroblast growth factors; use of siRNAs using novel delivery systems for target validation; pre-clinical validation/target identification of compounds identified through indigenous knowledge systems; molecular biology of cancer progression, including contributions of regulation of alternative splicing, intestinal stem-cell transcription factor and tumour suppressor gene to carcinogenesis.

 

What we are doing about...

1. Failure of anti-cancer drugs in early clinical trials

A large proportion of anti-cancer drugs fail in early clinical trials. Our aim is to improve cancer models so that they are more relevant to individual patients, and so are better able to predict whether a particular patient is likely to respond to a specific anti-cancer therapy.

We have developed models that incorporate close-to-patient cancer epithelial cells for a number of the hard-to-treat solid cancers including colorectal, lung, oesophageal, and pancreatic cancer, which are more representative of real patient tumours.

In addition, the models include supporting cell-types such as fibroblasts which, through paracrine signalling, influence the growth and metastastic capacity of the cancer epithelial cells as well as their response to anti-cancer drugs.

Incorporation of bioluminescent/fluorescent probes allow the growth and response of individual populations of cells to be tracked in real-time during each assay and changes in the tumour microenvironment/onset of biological processes that may influence drug response (e.g. hypoxia, angiogenesis, apoptosis) to be monitored.

Our 3D in vitro models allow a range of drugs and drug combinations to be tested in a 384-well format, thereby enabling prediction of how cells with particular molecular characteristics respond to specific drugs/drug combinations. Application of this technology in the clinic will allow better patient stratification and increase the success-rate of anti-cancer drugs.

 

2. Cancer genetics and stem cell biology

A mixture of cell populations exists in a tumour but it is the small population of cancer-cells, called cancer stem-cells (CSCs, tumour-initiating-cells), which replenish themselves and sustain the tumour growth.

We try to explore the cellular origin of cancer following the lineage-tracing, isolation, reprogramming strategies and understanding of the mechanisms regulating the different steps of cancer initiation and progression.

We generate in vivo and in vitro models in defining the molecular and cellular origin of tumours which allow the expression and/or deletion of key regulators involved in: i) protein metabolism and intracellular pathway mediating protein degradation via the E3-ubiquitin ligase FBXW7 (hCDC4), ii) nuclear transcriptional programs through canonical Wnt/β-catenin signalling and iii) key pluripotent stem cell (PSC) regulators such as NANOG.

We’re also developing methods for PSC-derived human intestinal tissues and selective-targeting of CSC-differentiation (differentiation-therapy).

 

Current projects

Our current projects include:

  • Regulation of tumour progression by alternative splicing
  • Paracrine signalling in cancer development/progression

Outcomes

Spinout company: Exonate Limited 

Exonate Limited is a speciality pharmaceutical company recently spun out of The University of Nottingham. It focuses on the discovery and development of the first in a new class of drugs--SPHINXes--which will modulate angiogenesis.

Exonate’s founders have discovered and patented a novel approach underlying the mechanism of action of VEGF to bring significant advances to VEGF based therapeutics. VEGF is a validated therapeutic target and anti-VEGF-directed therapy currently constitutes the gold-standard treatment for AMD and other neovascular diseases of the eye as well as being one of the mainstays of treatment for several cancers.

2013

A study to investigate blood vessel function during angiogenesis was recently awarded a £398,000-project grant by the Medical Research Council. The work, led by Professor David Bates, will identify how blood vessels control their function as they grow, leading to new targets to prevent or stimulate exchange of nutrients or drugs between circulating blood and surrounding tissues. (April 2013)
