Professor Grant Stewart received his first degree in Cellular and Molecular Pathology at the University of Bristol (1996). He subsequently joined the laboratory of Professor Malcolm Taylor at the University of Birmingham to do a Ph.D. studying the heterogeneity of the chromosomal instability syndrome, Ataxia-Telangiectasia (A-T), and the role of the ATM (Ataxia-Telangiectasia Mutated) gene in sporadic leukaemia. During the course of his Ph.D., he identified mutations in DNA double strand break (DSB) gene, hMRE11, also contributed to the development of a syndrome similar to A-T (A-T-like disorder or ATLD), firmly establishing a genetic link between the hMre11 DSB repair complex and ATM.

Continuing his growing interest in the cellular response to DNA damage, he moved in 2002, with a European Molecular Biology Organisation (EMBO) Long Term Fellowship, to the laboratory of Professor Stephen Elledge at Baylor College of Medicine (Houston, Texas). Whilst at Baylor, he identified a novel DNA double strand break repair protein called Mediator of DNA Damage Checkpoint 1 (MDC1) and demonstrated it played a role in recruiting other DSB responsive proteins to the sites of DNA breaks to facilitate repair and cell cycle checkpoint activation.

In 2005 Professor Grant Stewart moved back to the University of Birmingham with a CR-UK Career Development Fellowship to start up his own laboratory. During the course of this fellowship, his group identified a novel human immunodeficiency syndrome associated with defective repair of DNA DSBs called RIDDLE syndrome. Through a collaboration his laboratory was able to identify the gene mutated in RIDDLE syndrome as RNF168 and that the encoded protein facilitates the recruitment of DSB repair proteins, such as 53BP1 and BRCA1, to sites of DNA damage by promoting relaxation of the chromatin structure surrounding the break.

In 2009 Professor Grant Stewart received the Lister Institute Research Prize for his work on human DNA repair deficiency disorders. In 2011 Professor Grant was awarded a CR-UK Senior Fellowship to continue his research into understanding how the cell detects and repairs damage to its DNA and how defects in this process contribute to human disease and cancer development.

Current research in the Stewart laboratory focuses on the identification and functional characterisation of novel human disease genes associated with defects in DNA repair and/or abnormal DNA replication. The Stewart group has a long-standing interest in understanding how the ATM/ATR-dependent DNA damage response is regulated, how ubiquitin controls DNA double strand break repair and the link between the Fanconi Anaemia pathway and replication stress.

Genome instability is a genetic trait that is common to all cancer. Abnormal repair of DNA damage is the most frequent underlying cause of genome instability and probably represents the most important event that contributes to, and in some cases initiates the development of cancer. Therefore, cellular pathways that control the repair of damaged DNA as well as those that regulate cell cycle checkpoints and the apoptotic machinery represent an inherent anti-tumour barrier that must be surpassed for a tumour to develop. The principal focus of the laboratory is to determine how the cell detects and faithfully repairs damage to its DNA. The biochemical pathways involved in this process are collectively termed the DNA damage response (DDR) and consist of those that regulate DNA damage detection, cell cycle checkpoint activation, DNA repair and apoptosis.

Much of our insight about how DDR proteins function and the biological consequences if this fails, has come about from the study of rare inherited human syndromes associated with genome instability and a high prevalence of cancer e.g. Ataxia-Telangiectasia and Fanconi Anaemia. A large proportion of the research on going in the Stewart laboratory centres around understanding how defects in DDR pathways contribute to human disease (which includes providing a genetic diagnosis for patients with a suspected DNA repair deficiency disorder) and identifying novel human disease genes associated with genome instability and a predisposition to the development of cancer.

Current research in the Stewart laboratory:

• Identification and characterisation of novel genes within the ATR-dependent DNA damage response pathway that give rise to Seckel Syndrome and Microcephalic Primordial Dwarfism.
• Identification and characterisation of novel human disorders caused by mutations in genes that encode proteins involved in DNA replication.
• Investigating how different mutations in the ATM-Nbn-Mre11-Rad50 DNA double strand break repair pathway give rise to distinct clinical phenotypes.
• Understanding how histone methylation functions to prevent DNA damage-induced replication catastrophe.
• Discovering novel proteins that play a role in maintaining genome stability.
