I am Co Principal Investigator of the Arthritis Research UK Biomechanics and Bioengineering Centre in Cardiff University, where I lead the Preclinical Research Programme investigating the interaction between biomechanics and biology in joint tissues. I have established a platform of cell, animal and human models to investigate how mechanical load regulates joint pathology. My research elucidates new signalling mechanisms that regulate bone and cartilage turnover, to provide therapeutic and diagnostic targets for musculoskeletal diseases. This has led to the discovery of functional glutamatergic signalling in joint tissues, and revealed new pathways that mediate cytokine- and mechanically- induced cartilage degradation. My research focuses on translating glutamate receptor antagonists as a treatment for osteoarthritis, identifying mechanically-regulated biomarkers and developing a joint mimetic for drug screening.

I have led over 35 research projects (>£8M external funding, recently funded by Wellcome Trust, NC3Rs, Life Sciences Bridging Fund, MRC Confidence in Concept, Arthritis Research UK), invented patents and collaborate with academics, NHS clinicians and industry. I currently serve on Orthopaedic Research Society Programme Committee.

My research elucidates new signalling mechanisms that regulate bone and cartilage turnover, to provide therapeutic and diagnostic targets for osteoporosis, rheumatoid arthritis and osteoarthritis. This has led to the discovery of functional glutamatergic signalling in bone and synovium, and revealed new pathways that mediate cytokine- and mechanically- induced cartilage degradation. As a Team Leader in the Arthritis Research UK Biomechanics and Bioengineering Centre, I direct research investigating the links between pain, inflammation and pathology in human arthritis. We have developed a range of protocols and cell, explant, animal and human models to investigate how altered joint biomechanics influences biological signals.

Current research

Delineating the role of Protein Kinase R in arthritis.
Linking biological signals to joint loading and pathology in human arthritis.
Using Nuclear Magnetic Resonance Spectroscopy to identify complex patterns of biomarkers to stratify patients with arthritis or joint pathology.
Developing a novel, mechanically-loaded 3D co-culture system to investigate osteocyte control of osteoblasts

Glutamate Signalling

My work implicating the glutamate transporter GLAST-1 in mechanotransduction, and identifying glutamate as a potential anabolic target in bone is leading to new strategies for increasing bone formation. Our discovery that glutamate signalling mediates pathological responses in inflammatory arthritis, and that specific glutamate receptors are expressed in human inflammatory and osteoarthritis, reveals a therapeutic opportunity whereby joint destruction and pain could be prevented using specific glutamate receptor antagonists. http://www.news-medical.net/news/20130814/Osteoarthritis-research-an-interview-with-Dr-Deborah-Mason-Cardiff-University.aspx

PKR and ceramide in arthritis

Protein Kinase R (PKR) mediates stress and viral responses. We reported that PKR is activated in osteoarthritis and demonstrated that PKR mediates cytokine -induced degradation of cartilage. We have also shown that ceramide, a cytokine induced second messenger, influences cartilage matrix homeostasis via ERK signalling. P58IPK inhibits PKR and PERK and knockouts of this, where PKR and PERK are overactivated, have joint degeneration that resembles osteoarthritis. These new mechanisms of cytokine mediated cartilage degradation, relevant to both osteo- and rheumatoid arthritis, may be targeted in treatment or diagnosis of arthritis.

Biomechanics

Mechanical loading is a potent stimulus regulating both formation and degradation of bone and cartilage. Our studies on the effects of mechanical loading in bone and cartilage have implicated glutamatergic signalling, degradative enzymes, and the cytoskeleton in mechanotransduction. Recently, award of the Arthritis Research UK Biomechanics and Bioengineering Centre has allowed us to investigate the molecular signals underlying joint loading, pain and inflammation in humans with osteoarthritis or joint injury.

Ahmed Almansour

I am an enthusiastic and effective lecturer contributing to a range of teaching activities (tutorials, lectures, workshops, practical, projects) across various levels and Degree Schemes (BSc: Biomolecular, Biomedical, Medical, Dental; MSc). I adapt my methods according to student feedback, peer assessment and student achievement. As Level 1 Co-ordinator for Biochemistry Degree Schemes, Molecular Biology Degree Scheme Co-ordinator and Final Year Tutor for all Biomolecular Schemes I have made major contributions to management, teaching, course design and administration.

I currently Lead the final year Contemporary Topics in Disease Module, where cutting edge research in the School of Biosciences demonstrates how research can reveal pathological mechanisms and identify and test new treatments across a wide range of diseases.

After my BSc in Zoology and Genetics (1986) and my PhD in Evolutionary Genetics (1991) in Cardiff, I worked briefly in Medical Genetics at the University Hospital of Wales before moving to Bristol University. My research in Bristol revealed osteocyte gene expression in vivo and implicated glutamatergic signalling in mechanically-induced bone formation. Since my appointment as Lecturer in Cardiff University in 1996 (Senior Lecturer in 2009, Reader in 2012), I have investigated the role of glutamate transporters in bone, revealed a pathological role for glutamate in arthritis, and identified new pathways of cytokine- and mechanically- induced cartilage degradation involving PKR, ceramide and the cytoskeleton. I have secured over £12M of research funding for 30 projects. I co-ordinated Cardiff’s bid for the Arthritis Research UK-funded Centre of Excellence in Biomechanics and Bioengineering, where I act as a manager, and as the Biomechanics, Inflammation and Pain Team Leader. I have served on the Bone Research Society and the British Orthopaedic Research Committees. I have supervised 11 PhD/MD students and teach undergraduate students, co-ordinating the Molecular Biology Degree Scheme in Cardiff and acting as final year tutor for all Biomolecular Degree Schemes. I regularly contribute to public engagement activities with school children, patients and fundraisers.

I am interested in supervising students in the areas of:

developing new preventative treatments for osteoarthritis
early diagnosis of osteoarthritis
cell models for drug screening
