- Understanding genes, their regulation and function with emphasis on development.
- The genetic and molecular basis of inherited and degenerative skeletal disorders.
The Mission of her group is to make significant contributions through multidisciplinary synergistic partnerships and cutting edge science. Her group aspires to reach the long term Vision of “Bench to Bedside” research, translating discovery to the clinic. Some key contributions of her group are:
- Sox2 as a master “hearing gene”;
- Molecular insights into the function of Sox9, the master gene for development of cartilage;
- Discovery of a mechanism that explains how mutations causing ER stress in chondrocytes, can affect their differentiation and cell death and thereby cause skeletal disorders;
- Showed that chondrocytes become osteoblasts during bone formation and repair, thereby resolving a century-long debate about this possibility.
Professor Kathryn Cheah is Chair Professor of Biochemistry at The University of Hong Kong. She received a BSc degree in Biology from the University of London, U.K. and a PhD from the University of Cambridge, U.K. in Molecular Biology. After postdoctoral research in the University of Manchester (UK) and the Imperial Cancer Research Fund, London, she joined the University of Hong Kong in 1983. She was Head of the Department of Biochemistry from 1997-2009 and Director of the Li Ka Shing Faculty of Medicine Centre for Reproduction, Development and Growth from 2004-2009. She is Convenor of the University’s Strategic Research Theme on Development & Reproduction.
The driving motivation of her research is the realisation that, with an ageing population worldwide, genomic and regenerative medicine will play critical roles in helping to preserve healthy growth and quality of life. The Mission of her group is to make significant contributions through multidisciplinary synergistic partnerships and cutting edge science to enable ambitious research questions to be tackled. By applying the new knowledge to the development of strategies for the reconstitution or repair of tissues, her group aspires to reach the long term Vision of “Bench to Bedside” research, translating discovery to the clinic.
She is Director of a multidisciplinary collaborative group involving scientists and clinicians aiming to identify genetic factors that contribute to the risk of degenerative intervertebral disc disease (IDD), which is a common cause of lower back pain and disability. The group recently identified a new genetic risk factor for lumbar disc degeneration. These findings will contribute to a better prediction of total personal risk for IDD that will improve prevention and disease management.
She was awarded a Croucher Foundation Senior Fellowship in 2000 and was elected Fellow of The World Academy of Sciences (TWAS) in 2013. She was the founding President of the Hong Kong Society for Developmental Biology (HKSDB) serving from 2004 to 2013 during which time she represented Hong Kong in the Asia-Pacific Developmental Biology Network (APDBN) and the International Society of Developmental Biology. She was the President of the International Society for Matrix Biology 2006-2008. In 2012 she was elected to the Board of Directors of the International Society of Differentiation.
She was Co-Vice-Chair and Co-Chair for the Gordon Research Conferences (GRC) on Cartilage Biology and Pathology in 2009 and 2011 respectively. In 2012 she was appointed to the GRC Advisory Board for Hong Kong. She has organised several Croucher Foundation Advanced Study Institutes on Genetics and on Stem Cells and actively promotes public understanding of science.
