When cells reach a permanent growth arrest (Senescence) and resist death, this can result in numerous diseases, such as osteoarthritis. Here we show the presence of two different types of senescence in the blood metabolome of osteoarthritis patients. These blood metabolome patterns could function as biomarkers for patient-tailored targeting of senescence in OA. Accumulation [...]
Evelyn Houtman | 22-10-2022 | Aged human osteochondral explants as biomimetic osteoarthritis model: towards a druggable target in osteoarthritis This thesis aims to increase the understanding of human osteoarthritis pathophysiology by developing reliable biomimetic ex vivo human osteochondral explant models and focussing on the role of osteoarthritis-relevant triggers (mechanical stress) and interacting genetic factors [...]
Alejandro Rodríguez Ruiz | 22-09-2022 | Osteoprotegerin: a double-edged sword in osteoarthritis development To advance development of effective disease modifying OA treatments, a better understanding of its pathophysiological mechanisms is necessary. By studyinga family with early onset OA and high cartilage mineralization, a likely causal mutation in the TNF receptor superfamily member 11b (TNFRSF11B) [...]
Margo Tuerlings | 27-09-2023 | The bone and cartilage interplay in osteoarthritis: key to effective treatment strategy. Osteoarthritis (OA) is a prevalent age-related joint disease, determined by diverse changes in pathways maintaining articular cartilage and subchondral bone. This thesis aimed to identify and study gene networks driving interacting etiopathophysiological OA processes in cartilage and [...]
Marcella van Hoolwerff | 06-09-2022 | Dissecting cellular function of fibronectin in osteoarthritic cartilage The aim of this thesis was to combine transcriptomics, genetics and human disease modelling to obtain further insight into molecular processes underlying osteoarthritis. More specifically, we aimed to elucidate the role of long noncoding RNAs expression changes as aberrant epigenetic [...]
1H-NMR metabolomics-based surrogates to impute common clinical risk factors and endpoints | 2022 Jan;75:103764 | EBioMedicine | doi: 10.1016/j.ebiom.2021.103764 Bizzarri D, Reinders MJT, Beekman M, Slagboom PE, BBMRI-NL, van den Akker EB. Abstract Background: Missing or incomplete phenotypic information can severely deteriorate the statistical power in epidemiological studies. High-throughput quantification of small-molecules in bio-samples, i.e. 'metabolomics', [...]
