Disease relevance of COMP

  • Moreover, the COMP heptamer was preferentially recognized by circulating IgG in RA (n = 22) compared with osteoarthritis patients (n = 24) or age-matched healthy controls (n = 20; both p < 0.0001) [1].
  • Thus, increased COMP levels in body fluids may be indicative of active synovitis as well as of accelerated joint erosion [2].
  • TSP-1 and COMP were also detected in areas of microcalcification in atherosclerotic lesions and TSP-1 was detected adjacent to areas of calcification in calciphylaxis [3].
  • Clinical and radiographic features of multiple epiphyseal dysplasia not linked to the COMP or type IX collagen genes [4].
  • Normal human chondrocytes were transfected with wildtype (wt-) COMP or with mutant COMP (D469del; mt-) recombinant adenoviruses and grown in a nonattachment redifferentiating culture system that provides an environment allowing formation of a differentiated chondrocyte nodule [5].
  • Genetic variations of the COMP gene may account for some subgroups of benign joint hypermobility [6].
 

Psychiatry related information on COMP

  • When adjustment was made for markers of sexual risk taking, only genital warts remained significantly (p = 0.05) associated with SFM as compared to both SSM and COMP [7].
  • The D2-like antagonist haloperidol produced a dose-related decrease in locomotor activity when administered alone, and blocked the hyperactivity effects of PCP over the same dose-range (minimal effective dose, MED = 0.3 mg/kg for both effects) [8].
  • The distribution of profiles containing the m2-muscarinic acetylcholine receptor within the aged human basal forebrain and its relationship to cholinergic and noncholinerigc neurons and alterations in Alzheimer's disease (AD) was investigated by using an m2-specific monoclonal antibody (Levey et al. [1995] J. Comp. Neurol. 351:339-356) [9].
  • Hemolin is also developmentally regulated as suggested by changes in its concentration during larval and pupal ecdysis (Trenczek, T., 1998. Endogenous defense mechanisms of insects. Zoology 101, 298-315; Lanz-Mendoza, H., Faye, I., 1999. Physiological aspects of the immunoglobulin superfamily in invertebrates. Dev. Comp. Immunol. 23, 359-374) [10].
  • METHODS: They randomly assigned 34 (largely chronically) depressed individuals age 60 and older to receive 28 weeks of antidepressant medication plus clinical management, either alone (MED) or with the addition of dialectical behavior therapy skills-training and scheduled telephone coaching sessions (MED+DBT) [11].
 

High impact information on COMP

 

Chemical compound and disease context of COMP

 

Biological context of COMP

 

Anatomical context of COMP

  • Compared with a matched normal population, increased concentrations of cartilage oligomeric matrix protein (COMP) were found in all patients who developed rapid hip joint destruction [23].
  • RESULTS: COMP was synthesized and secreted by synovial cells as well as by articular chondrocytes in culture [2].
  • COMP was not detected in culture media of skin or fetal lung fibroblasts, either in the absence or the presence of TGFbeta1 [2].
  • The demonstration of COMP expression in surgical specimens of synovial tissues suggests that the inflamed synovium may provide an additional source for the elevated levels of COMP observed in arthritis [2].
  • Because COMP exists as a homopentamer, only one mutant COMP subunit may result in an abnormal complex that is accumulated in expanded rough endoplasmic reticulum (rER) cisternae, a hallmark of PSACH [24].
 

Associations of COMP with chemical compounds

 

Physical interactions of COMP

 

Regulatory relationships of COMP

  • RA SF presented more cell surface integrins, and monoclonal antibodies against CD51 inhibited the adhesion to COMP by 80% [34].
  • These results indicate that COMP expression within these cells is regulated in a unique manner that differs from the expression of other extracellular matrix genes [21].
  • CONCLUSION: COMP is highly expressed within the tumor cells of HCC, suggesting that COMP might play a role in the pathophysiology of this disease [35].
 

Other interactions of COMP

  • Because of the exclusion of the EDM1 and EDM2 loci in some families, the existence of a third locus has been postulated [36].
  • The analysis resulted in identification of three mutations in COMP and one in COL9A1, but none in the other two collagen IX genes [37].
  • Type IX collagen and matrilin-3 (MATN3), also accumulate in the rER cisternae of PSACH chondrocytes, but it is unknown how mutant COMP interacts with these proteins [24].
  • The elevated levels of COMP were similar to those found in joint injury or osteoarthritis, and the elevated levels of MIA were comparable to those reported in rheumatoid arthritis [38].
  • The COMP gene mutation (C348R), while not previously published, is typical of those in PSACH patients, whereas the COL2A1 mutation (T1370M) is somewhat atypical, as it predicts an amino acid change within the carboxyl-terminal region of the protein [39].
  • Our data indicate that COMP/TSP5 is an aggrecan-binding protein, and this interaction is regulated by the calcium-sensitive conformation of COMP/TSP5; interaction of COMP with aggrecan can be mediated through the GAG side chains on aggrecan and the "signature domain" of COMP/TSP5 [40].
