About

Lesley Tannahill has worked in a wide variety of Biomedical research teams in the UK and Switzerland and has gained a lot of expertise in Molecular Biology, Epigenetics and Proteomics. Recent experience has included a strong clinical component with emphasis on Cancer Research.

Qualifications

  • PhD in Medicine 1987 
  • BSc (Hons) Pharmacology, University of Edinburgh, 1983

Biography

Lesley Tannahill qualified with a BSc (Hons) in Pharmacology from the University of Edinburgh in 1983. She then went on to study for a PhD in Neuroendocrinology (Medicine) at the MRC Brain Metabolism Unit in Edinburgh. In 1986 she moved to Switzerland to gain more experience in the Molecular Sciences.

Since then, Lesley has worked mainly on Endocrine related Cancer in Switzerland and the UK. During the last few years in Birmingham, Lesley’s research focus has switched to looking for DNA methylation biomarkers that could be used in a screening test for Colorectal Cancer.

Research

Lesley is working on the development of a non-invasive screening test for pre-symptomatic diagnosis of colorectal cancer. Colorectal cancer (CRC) is the third most common malignancy in the world and is the second leading cause of cancer mortality. However, survival rates are good if the cancer can be detected at an early stage and surgically resected.

Epigenetic alterations, such as CpG island methylation are known to play an important role in driving neoplastic change and may provide a valuable target for the identification of early tumours. Novel target genes have been identified using methylation micro arrays. Validation of these results by Pyrosequencing has shown these genes to be frequently hypermethylated in premalignant colorectal adenomas.

In collaboration with MRC-Holland, Lesley is establishing a screening assay in stool DNA to examine the methylation pattern of up to 26 of these methylation markers in stool DNA using Multiplex-Ligation-dependant-Probe-Amplification (MLPA) technology.
