Cancer cytogenetics
Research Achievements
My research has focused over the past 35 years on chromosome organisation and how
disruption of that organisation relates to human disease. My early work on cancer
cytogenetics identified novel non-random chromosome abnormalities together with their
prognostic implications, and helped unravel the genetic basis of complete and partial
hydatidiform moles. My thesis work in the Genetics Laboratory Oxford achieved improved
mapping for several human disease genes, including Duchenne muscular dystrophy,
haemophilia B and cystic fibrosis, and led to collaborative work on XY homology and
telomere structure. Moving to the Molecular Haematology Unit, my work has continued on
genetic analysis of human disease, including leukaemia, alpha thalassaemia with mental
retardation (ATR16), congenital dyserythropoietic anaemia (CDA1), but is principally now
concentrated on chromatin organisation and the regulation of globin gene expression.
Understanding fundamental aspects of gene regulation can provide insights into disease
processes. My group has found, within a model of erythroid differentiation, that the tendency
of genes to associate within the nucleus, which varies between different genes, is directly
dependent on the surrounding chromatin environment. We find that spatial associations are
a frequent occurrence between some active genes but that this is not due to shared
transcription factories and is not a functional necessity for transcription. We proposed that
active genes, particularly those on stretches of decondensed chromatin, can be brought into
close proximity on a probabilistic basis by the nucleation of multiple splicing associated
proteins and small nuclear ribonucleoproteins into nuclear speckles. Our findings contribute
to the growing body of evidence that the central processes of transcription, replication and
repair are all self-organised within the nucleus. We are now focusing on the physical
organisation of chromatin across the alpha globin gene regulatory region during erythroid
differentiation to determine the chromatin conformations required for active transcription.
Future Aims
The alpha globin gene region is one of the best-characterised segments of the genome and
it is an ideal model with which to investigate how chromatin domains are established and
altered during the course of development and differentiation. Analysis of single cells will be
an essential complement to the genome-wide studies of chromatin configurations
undertaken within the Unit. We plan to look in detail at the kinetics of transcription and at
spatial relationships within the alpha globin regulatory region in live cells, using superresolution microscopy. We will ask what part chromatin looping, involving enhancers and
promoters, Polycomb-bound sites and boundary elements, and chromatin condensation
contribute to gene regulation. Close collaboration with the Higgs group gives us access to a
range of potentially informative knockouts whilst we can characterise nascent transcription in
the various erythroid models. The organisation of transcription sites within the nucleus
requires further clarity and the arrival of STED imaging in the WIMM will allow us the look in
fine detail at the positioning of the globin genes with respect to RNA polymerase II and other
critical nuclear proteins.
In addition to these fundamental aspects of gene regulation we continue to characterise
disorders of red blood cells. Having identified a second gene underlying congenital
dyserythropoietic anaemia type 1 (CDA1) we are undertaking functional studies to
investigate the role that the two CDA1 genes, CDAN1 and c15orf41, play in normal
erythropoiesis, and why mutations in either of these genes cause such devastating
disruption to chromatin structure in erythroblasts.
The aims of my programme have been planned to integrate closely with the work of the
Higgs group to ensure a smooth transition on my retirement. To further that end my postdoc
Chris Babbs is also taking forward several projects, looking at unexplained anaemias,
unexpectedly severe thalassaemia, unlinked beta thalassaemia, surviving fetal hydrops and
zeta globin regulation, with the ultimate aim of restoring balanced globin expression in
thalassaemia patients.
How do These Aims Contribute to the Understanding and/or Management of Human
Disease
The breadth of my research programme uses both basic science and more clinicallyorientated projects to gain an understanding of human erythropoietic diseases. By
establishing principles governing successful transcription from the alpha globin genes we
hope to contribute to an understanding of how normal transcription may be restored in
disease. Conversely human erythroid disorders can shed light on the normal processes
required for transcription. We are unpicking the genetic abnormalities associated with
ATR16 syndrome, investigating the cause of erythroid abnormalities found in CDA1 and the
basis of a range of haemoglobinopathies. At a clinical level our findings have already been
very useful in family studies and genetic counselling.
Lay Summary of Research
Now that the human genome has been sequenced, the challenge for scientists is to
understand the normal functions of our genes and how those become disrupted in disease.
Such work may then allow us to develop novel therapies to counteract the effects of the
disregulation underlying genetic disease. We are concentrating on how the alpha globin
genes are normally switched on to produce globin protein during the development of red
blood cells. We want to see how specific regions of DNA are organised in a cell nucleus and
what may disrupt that organisation to affect protein production. We are also looking at other
genes than can have defects causing anaemias and thalassaemias. In addition to giving us
an understanding of how red blood cells develop, this work can be very useful for individual
families needing genetic counselling.
