The Butterworth group work on applying synthetic and biological chemistry to study and solve biological problems of relevance to human health. One key theme of this work is the utilisation of the cell’s biological machinery to selectively activate molecules to kill cancer cells with specific mutations, or to selectively reprogram the activity of key immune cells. We have several breast cancer focussed collaborations with biomedical researchers and clinicians at Manchester and beyond. These include projects with funding from the Wellcome Trust (~£5 million seeding drug discovery award, looking at novel kinase inhibitors in TNBC), CRUK and MRC CiC (together ~£400k, looking at novel kinase modulators as immune-oncology agents in TNBC with Katie Finegan).
My research group investigates the mechanisms by which mitogen-activated protein kinases (MAPK) regulate cancer biology and therapeutic response, with a particular focus on triple-negative breast cancer. Using a combination of established pharmacological inhibitors, novel and exclusive pre-clinical mouse models, human samples and in vivo techniques, my group’s central aim is to translate findings at the molecular level into valid therapeutic avenues and/or biomarkers of cancer progression and therapy response. Current projects include studies into ERK5 and MEK5 inhibitors, and further characterisation of the role of ERK5 in inflammatory responses and metastatic spread.
During development, cells transition from a progenitor state to differentiation with defined timing, or to quiescence from which they may be reactivated. Understanding how such transitions and their timing are regulated is key in understanding how tissues are built, maintained, repaired or subverted in disease.
In recent years, our understanding of how cells make cell state transitions has been transformed by the application of single cell molecular technology that revealed a large degree of non-genetic heterogeneity in seemingly homogeneous populations of cells. In neural progenitors, single cell imaging with unstable reporters has revealed asynchronous pulsatile fluctuations in regulatory gene expression, which is masked by static measurements of population averages. Thus, cell fate transitions may not be driven simply by genes being turned on or off, but by a change in the dynamics of gene expression for example, from fluctuating or pulsatile expression to a more stable state.
Cells in every organism can process external signals thanks to clever systems that enable the information encoded by the signals to be transmitted inside the cell. These systems, also known as pathways, allow healthy cells to communicate with each other and to respond to changes in their environment. Consequently, diseases can occur when these networks are disrupted or inappropriately stimulated. For example, we have identified a pathway that causes cancer cells to grow and divide in an uncontrolled manner, forming a tumour. We have also found that a similar pathway is responsible for instructing brain cells to die. The importance of this finding is highlighted by the fact that excessive loss of brain cells is associated with neurological disorders characteristic of age-related degenerative diseases or associated with brain injury. Based on these initials findings my laboratory is interested in understanding how pathways transmit specific information within the cells, so that strategies to repair networks of signal transduction can be developed to treat diseases.
The tissues of our bodies are extremely complicated at the cellular level, comprising different types of cells arranged with precise geometry. Within this complex system, the direction in which a cell divides is a crucial tool used to shape tissues and determine cell fate. Defects in division orientation have lethal consequences: they cause failures in embryonic development and are associated with cancer.
To coordinate cell division across a tissue, cells must be able to “read” their external cellular environment and orient their division accordingly. The mechanisms that control this remain unclear, but we know that cues from the extracellular matrix play a vital role. These cues must be fed to a cellular structure called the mitotic spindle, the positioning of which determines cell division orientation. Understanding the mechanisms used by the cell to correctly position the spindle is a key focus of our lab. In particular, we are investigating how molecular forces are balanced inside the cell to position the mitotic spindle and how these internal mechanisms are linked to the external cellular environment in order to coordinate spindle orientation across a tissue.
Mr Mohammed Absar
Clinical Director of the Greater Manchester Cancer Breast Pathway Board
Roger Hunt has been a consultant histopathologist at Wythenshawe Hospital, Manchester since 2011. His special interests include breast pathology, particularly the immunohistochemistry of prognostic and predictive markers. Roger actively supports various aspects of ongoing clinical research at Wythenshawe and has a strong background in multi-professional medical education. Roger has held Foundation Programme Director, Director of Medical Education and RCPath NW Learning lead roles and is a visiting professor at Manchester Metropolitan University, where he is the clinical lead for the Scientist Training Programme MSc course.
Roger was the Chair of the Greater Manchester Breast Clinical Subgroup from 2007-9. He is a member of the UK NEQAS Immunohistochemistry Scientific Advisory Board and has advised on the revision of national NICE guidelines for early and locally advanced breast cancer and also cancers of unknown primary origin.
Roger has held various roles at the Royal College of Pathologists, and is an FRCPath examiner for the and has been a member of the England Regional Council and the Working Group on Cancer Services.
Medical Physicist and Lecturer
I am a Consultant Histopathologist with 15 years’ experience working at Manchester Foundation Trust Wythenshawe Hospital, subspecialising in breast pathology. Our unit reports over 1000 breast cancers per year, being one of the largest in the UK. My work is predominantly clinical, including work for the NHS Breast Screening programme, for which I am one of the North of England’s Clinical Professional Advisors. My main research interests are in the prevention of breast cancer, offering histopathological advise to surgeons and oncologists working in this field.
Professor of Experimental Therapeutics
CRUK MI Group Leader in Immuno-Oncology
Dr Zelenay obtained his undergraduate degree in biology from the University of Buenos Aires in 2002. As a student he worked on DNA vaccines in the laboratory of Juan Fló. He then undertook his Ph.D. in Immunology at the Institute Gulbenkian of Science in Portugal where he studied regulatory T cells, working with Jocelyne Demengeot and Antonio Coutinho. In 2008, he joined the group of Caetano Reis e Sousa at the Cancer Research UK (CRUK) London Research Institute and later at The Francis Crick Institute, where he was awarded Marie Curie and EMBO fellowships to investigate innate immune receptors and signaling pathways that trigger dendritic cell activation and drive T cell responses against viruses or tumours. In 2015, Dr. Zelenay joined the CRUK Manchester Institute as a Junior Group Leader to form the Cancer Inflammation and Immunity Group. His group focuses on understanding the underlying mechanisms that mediate cancer-inhibitory versus tumour-promoting inflammation in order to design new therapies for cancer patients. In 2017, he received the CRUK Future Leaders in Cancer Research Prize.
