Osteoarthritis

Evaluating the causal effect of circulating proteome on the risk of osteoarthritis-related traits

Ann Rheum DisPublished Mendelian randomisation study

Authors' conclusion

Through MR analysis, we have identified numerous plasma proteins associated with OA-related traits, shedding light on protein-mediated mechanisms and offering promising therapeutic targets for OA.

Study context

Population
Thousands of plasma proteins and 12 osteoarthritis (OA)-related traits
Outcome
Circulating proteins causally associated with OA-related traits
Methodological detailstwo-sample Mendelian randomisation (MR), Bayesian colocalisation, Steiger filtering analysis
  • Two-sample MR
  • Bayesian colocalisation
  • Steiger filtering analysis

Main finding

As reported in the abstract

Circulating proteins with putatively causal effects on OA-related traits
  • Dozens of circulating proteins identified with putatively causal effects on OA-related traits
  • Majority of these proteins were drug targets or considered druggable
