Home / About / Academic staff profiles / Health and Clinical Sciences / Timothy Barrow

Senior Lecturer in Genomics

I joined the University of Sunderland in 2017, following postdoctoral positions at Universitätsklinikum Freiburg (Germany), Brigham and Women's Hospital (Boston, USA) and the Northern Institute for Cancer Research (Newcastle, UK).

My main research interests are in the field of cancer epigenetics, predominantly in relation to the development and progression of chronic lymphocytic leukaemia.

I also have an interest in the effects of environmental exposures upon the epigenome, such as the effects of particulate matter air pollution, which I will be pursuing through collaborative work with Project ELEFANT.

Teaching and supervision

I lecture on topics related to genetics, epigenetics and cancer, mainly for BSc (Hons) Biomedical Science.

Research interests for potential research students

I am able to supervise students on projects related to genetic and epigenetic changes in leukaemia.

Research

My main research interests are in the field of cancer epigenetics and epigenetic epidemiology.

My postdoctoral work at Universitatsklinikum Freiburg (Germany) and Brigham and Women's Hospital (Boston, MA) focussed upon epigenetic changes in solid tumours, such as loss of genomic imprinting in breast cancer (Int J Cancer 137(3): 537-47) and smoking-associated hypermethylation of the APC tumour suppressor gene in colorectal cancer (J Pathol 243(3): 366-75).

At the Northern Institute for Cancer Research (Newcastle University, UK) I developed an interest in the chronic lymphocytic leukaemia (CLL) epigenome. My work has focused on epigenetic changes during disease progression that modulate drug sensitivity, and analysis of retrotransposon (LINE-1 and Alu) methylation.

I also have an interest in epigenetic changes in response to environmental exposures, especially with regard to how these are implicated in carcinogenesis. My collaborative work has included examining the impact of morphine exposure on nuclear and mitochondrial DNA methylation in different regions of the rat brain (Epigenetics 12(12): 1038-47) and demonstrating, for the first time, that exposure to carcinogenic compounds and endocrine disruptors can modify RNA m6A methylation (Environ Res 175: 228-34).
