23. lubricin is expressed in the TMJ disc bilaminar zone; lubricin may have a role in normal disc posterior attachment physiology through the prevention of cellular adhesion as well as providing lubrication during normal bilaminar zone function PMID: 21955422
24. Lubricin is expressed in chondrocytes derived from osteoarthritic cartilage encapsulated in poly (ethylene glycol) diacrylate scaffold. PMID: 22073377
25. The surface layer of lubricin coating torn edges of anterior cruciate ligaments and menisci may interfere with the integrative healing process needed for repair. PMID: 21647956

27. O-linked oligosaccharides NeuAc alpha2-3Gal beta1-3GalNAc and NeuAc alpha2-3Gal beta1-3(NeuAc alpha2-6)GalNAc were the dominating structures on lubricin. The latter was more prevalent in rheumatoid arthritis, indicating that sialylation is up-regulated. PMID: 20443780
28. HAPO enhanced total adherence of HUVEC in a concentration-dependent manner. PMID: 19900364

35. In the human knee, cartilaginous deposits and osteoarthritic cartilage contained PRG4 in patients with advanced knee osteoarthritis. PMID: 17343281
36. Lubricin provides synovial fluid with an ability to dissipate strain energy induced by mammalian locomotion, which is a chondroprotective feature that is distinct from boundary lubrication. PMID: 17404241
