Analyzing the role of cAMP and STAT3 signaling in cartilage homeostasis and osteoarthritis development – Grant # R00 AR077090

  • Principal Investigator: Zhaoyang Liu, Ph.D.
  • Sponsor: National Institutes of Health
  • Period: 03/14/2023-02/28/2026
  • Goal: To utilize mouse genetics, combined with modern genomics and pharmacological approaches, to define the role of cAMP and STAT3 signaling in articular cartilage homeostasis and OA pathogenesis, which may accelerate our diagnosis and treatment of human OA.

Investigating the ADGRG6/GPCR signaling pathway in cartilage homeostasis and musculoskeletal disorders

  • Principal Investigator: Zhaoyang Liu, Ph.D.
  • Sponsor: Herman Ostrow School of Dentistry at USC, Start-up Fund from Provost
  • Period: 06/01/2022-6/01/2025
  • Goal: This proposal investigates the functional role of a G protein-coupled receptor (GPCR) named ADGRG6 in cartilage maintenance and multiple musculoskeletal disorders.
