Charles obtained his first degree in Biochemistry at the University of Cambridge. He studied for a PhD at the University of Leicester with David Critchley, the CRUK executive director of science. This was followed by postdoctoral work on the 5th floor of the Imperial Cancer Research Fund Laboratories in London, with Beverly Griffin. Charles then carried out a long-term EMBO-fellowship and a Fogarty International fellowship at the Lawrence Berkeley National Laboratory in California, with Mina Bissell, the president of the American Society of Cell Biology. He was then awarded a Senior Research Fellowship in Basic Biomedical Science by the Wellcome Trust to set up his own laboratory at the University of Manchester in 1992.

Charles jointly established the Manchester Breast Centre, a pan-Manchester organisation uniting basic and clinical scientists working on mammary gland biology and breast cancer in 2005, and co-founded the Manchester Breakthrough Breast Cancer Research Unit in 2009. He was appointed to the position of Director of the Wellcome Trust Centre for Cell-Matrix Research from 2009 to 2014. Charles has also served on the board of the British Society of Cell Biology, on research committees for the Medical Research Council and Cancer Research UK, and was elected to become a Fellow of the Royal Society of Biology in 2013.

Research

Charles’ scientific achievements have been to discover mechanisms by which cell-matrix interactions control developmental morphogenesis, survival and proliferation, as well as tissue-specific gene expression, in epithelial tissues. By focusing on breast biology, he revealed the central role of integrin adhesion receptors in mammalian cell behaviour, providing a general framework for understanding epithelial tissue development and function.

He discovered that integrins control cellular differentiation, and identified a molecular pathway linking integrins with tissue-specific gene expression. His laboratory also revealed that cell-matrix interactions determine apoptosis by controlling Bax trafficking between cytosol and mitochondria. Charles’ group further discovered that integrins determine the orientation of cellular polarity in breast, and that this occurs via endocytosis of apical components away from cell-matrix adhesions.

Now Charles is evolving completely novel areas of research on cell-matrix interactions. He is determining how the micro-mechanics of breast tissue has a central role in starting cancer in women, as well as the links between cell-matrix adhesion and circadian clocks in breast biology. He is also investigating how the small GTPase, Rac1, contributes to breast development and cancer.  

In public engagement, Charles has supervised work experience for A Level students, delivered biology activities at local schools, and participated over many years in science exhibitions & events for children in the Faculty of Life Sciences, at the Whitworth Art Gallery, and at the Manchester Museum.

Research topic - How cell-matrix adhesion controls breast biology

The breast is an organ that contains an intricate network of epithelial ducts and associated alveoli, which are embedded within a stromal connective tissue made up of extracellular matrix. The alveoli are milk factories and the ducts are tubes that transport milk to the nipples. Both require the matrix to develop properly, and for the breast to work as a secretory organ. Understanding the molecular basis for how cell-matrix adhesion controls breast biology underpins the research in our laboratory.

The way that epithelia form and function, and become deregulated in disease, is a fundamental biological question of our time. My research focusses on how cells translate the language of their extracellular matrix into the responses that underpin tissue behaviour. We study the breast because it is an excellent system for uncovering basic principles of cell and developmental biology, and because our work can reveal new targets for treating breast cancer. We’d like to know how the cellular microenvironment controls breast epithelial cell function and how it influences rhythmic variations in everyday circadian cycles. We are also determining how the matrix impacts on the susceptibility of breast epithelia to become cancerous. Importantly, the molecular principles that define how the epithelia of breast tissue function will reveal mechanisms underpinning the biology of all epithelia.

Sometimes, cells in ducts or alveoli can become cancerous. One of the central problems in cancer is that cell adhesion to the extracellular matrix changes. Either the matrix stiffens, or the cell’s integrin receptors adjust subtly, or alternatively the intracellular enzymes that integrins control become mutated. The cells then don’t know how to behave properly. For these reasons, we are also determining how altered cell-matrix interactions are involved with the onset of breast cancer in susceptible patients.

Current main scientific interests

1: Differentiation and breast biology. Over many years we have studied the lactation programme, demonstrating a key role for the cellular microenvironment in breast function. Using 3D-culture models, and cells with altered gene expression, as well as gene knockouts in vivo, we discovered that integrin receptors and their downstream signalling molecules, are crucial for the formation of a lactating tissue that makes milk. Altered cell-matrix interactions and integrins also have central roles in the onset and progression of breast cancer, leading us to pursue new medically-related research areas: i) With Dr Andrew Gilmore, we are exploring how the signals derived from extracellular matrix can alter normal breast cell behaviour to cause cancer. ii) With Dr Marco Domingos and engineering colleagues, we are developing 3D-bio-printing methods to contribute to those studies. iii) With Dr Ahmet Ucar, we are studying the integrin-signalling protein Rac1, focussing on its role in both normal and cancerous breast tissue. iv) In work with Dr Pat Caswell, we are looking at novel ways that prolactin signalling is controlled.

2: Mammographic density and breast cancer risk. High mammographic density, and the consequent stiff tissue microenvironment provided by the extracellular matrix, is one of the greatest risk factors for breast cancer. However the mechanisms by which ‘stiffness’ contributes to cancer are not understood at all. In collaboration with Drs Mike SherrattRob Clarke and clinical colleagues, our research is examining how breasts with different mammographic densities are formed. We are also investigating how ‘mechanotransduction’ pathways control the way that epithelial cells behave and how they might trigger breast cancer in post-menopausal women. In detail, we are delving into the biophysics of breast density in several ways. These include: i) looking at breast structure, molecular architecture and protein/RNA/DNA composition, and determining how this differs between normal and tumour areas in women with different density breasts; ii) characterising the relationship between global mammographic density, local tissue structure/mechanics, and X-ray attenuation in cancerous and non-cancerous breasts, and how this leads to different densities; and iii) exploring breast micro-structure at the atomic level to determine how matrix architecture affects X-ray attenuation. iv) We also trying to understand how the breast epithelium influences stromal structure and density.

3: Circadian clocks in the breast. In collaboration with Prof Qing-Jun Meng, we showed that there are >600 genes in the breast that are expressed with circadian time-keeping, but that clock amplitude diminishes in ageing, probably due to stiffening of the stromal matrix. Mechanotransduction suppresses clocks through a talin-vinculin-Rho pathway that controls the actin cytoskeleton. Moreover, genetically deleting clock genes prevents stem cell survival, providing a circadian link between the matrix and breast stem cells. i) Now we aim to determine the role of clocks in normal breast development and lactation, and to ask whether clocks are required for ductal and lobular mammary epithelial function for the duration of life. ii) Since clocks are strongly regulated by stromal stiffness, we are examining whether high mammographic density contributes to breast cancer by altering the circadian system. iii) Clocks are reduced during ageing and are strongly linked to breast cancer, so we are establishing whether restoring normal clocks in breast cancer cells can rescue inappropriate growth. iv) Finally we’d like to understand the molecular links between a stiff stroma and deregulated clocks, so we’re dissecting the roles of known stiffness-regulators of gene expression including Nesprin/Sun proteins, and the Yap/Taz and the MRTF/SRF transcriptional control pathways in breast biology.
