Cancer and Genome stability
Cancer and Genome stability
The following groups perform research in this area:
SNF2 ATPases in genome stability and cancer
The maintenance of complete and undamaged genome is critical for survival. Because DNA is continuously exposed to genotoxic stress, cells have evolved different mechanisms that are specialised for correcting different types of DNA damage. These mechanisms play critical roles in the maintenance of genome integrity, and their...
DNA repair mechanisms and human disease
Our genome is constantly exposed to various types of DNA damage, both endogenous and exogenous. It has been estimated that the DNA in every cell of our body suffers thousands of DNA lesions per day, which, if left unattended, can lead to mutations and/or cell death. Our cells have evolved a variety of mechanisms to counteract...
Transcription factories; genome organization and gene regulation.
Human chromosomes are arguably the largest and most important biomolecules, but many aspects of their structure – and how structure affects function – remain unresolved. Our ultimate goal is to elucidate how the genome is folded, and how folding determines function. To this end, we apply a multi-...
Genome Stability and Cell Cycle
Our research goal is to elucidate how proliferating human cells safeguard their genomic DNA against various stresses coming from the environment (e.g., UV, radiation, chemicals) and from normal processes of cell growth (e.g., metabolic byproducts, DNA replication, transcription).
Regulation of mitotic progression and chromosome segregation
Cell division is the fundamental basis for growth and development of an organism. Millions of cell divisions have to occur before an organism reaches its final size. Throughout the life span of an organism, blood, skin and intestinal cells have to be constantly replaced by further cell division. High fidelity...
Structure and function of genes that regulate tumour phenotypes
Multiple cellular pathways are deregulated in tumours, some of which alter growth and the propensity for tumour cells to invade and spread to other sites. Our group focuses on two imprinted genes frequently disrupted in cancer, IGF2 ligand and IGF2 receptor (IGF2R). We have studied the structural basis of...
DNA replication and genome stability
Complete, accurate replication of the genome is crucial for life. Errors during DNA replication give rise to mutations that cause genetic disease; failures during genome replication directly underlie several human disorders. DNA replication is the direct target of many chemotherapeutic agents.
Post-transcriptional regulation of gene expression in cancer.
We study post-transcriptional aspects of gene regulation, and specifically how these differ between cancer cells and their normal counterparts. One project in this area focuses on translation initiation factor eIF3e (also known as INT6), high levels of which in breast cancer are...
Molecular dissection of centrioles, centrosomes and cilia
Centrioles organise the assembly of two important cell organelles: centrosomes and the cilia; our goal is to understand how these organelles function at the molecular level.
Molecular pathology of post-translational modification
The group is interested in the molecular mechanisms by which pathological perturbations in the post-translational modifications of proteins (including proteolytic maturation, oligomeric assembly, ubiquitination, phosphorylation and fatty acyl modification) can lead to severe human disease. Conditions resulting from...
