OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Evolutionary Selection and Constraint on Human Knee Chondrocyte Regulation Impacts Osteoarthritis Risk
Osteoarthritis has a considerable heritable component, with GWAS variants residing in non-coding sequences near chondrocyte genes; loci which likely became evolutionarily optimized during bipedal knee formation. To explore this relationship, we epigenetically profiled joint chondrocytes, revealing evidence of selection and constraint on human knee-specific regulatory elements. These elements also overlap osteoarthritis loci, with risk variants contributing to disease heritability by altering constrained sequences. Using these findings we then describe a causal enhancer variant present in half the world’s population, showing that it impacts mouse knee-shape and osteoarthritis. Overall, our methods link an evolutionarily novel aspect of anatomy to its pathogenesis.
