Publication Link Summary of findings
18060880 These data indicate that S100A8/A9-induced cell death involves Bak, selective release of Smac/DIABLO and Omi/HtrA2 from mitochondria, and modulation of the balance between pro- and anti-apoptotic proteins.
17636430 Report showed S100A9 was expressed human bone and cartilage cells and may contribute to calcification of the cartilage matrix and its replacement with trabecular bone, and to regulation of redox in bone resorption.
17787039 Data suggest that S100 proteins calprotectin and S100A12 are related to radiographic changes rather than disease activity in psoriatic arthritis with low disease activity.
17936757 The homo-oligomeric forms of S100A8 and S100A9 are readily degraded by proteases, and the preferred hetero-oligomeric S100A8/A9 complex displays a high resistance even against proteinase K degradation.
17852869 Serum calprotectin (S100A8/S100A9)and S100A12 are increased in children with inflammatory bowel disease and indicate disease activity.
17895549 MRP8/14 may be involved in the pathogenesis of sarcoid granulomas. The measurement of serum MRP8/14 levels is useful for the diagnosis of sarcoidosis.
13130482 Since MRP-8/MRP-14 exhibit direct effects on leukocyte adhesion to the vascular endothelium, their extensive expression in the epidermis indicates an active role for these S-100 proteins in the initial phase of this systemic autoimmune disease.
17126494 Authors hypothesize that L1AG might become internalized nonspecifically into target cells, perhaps by pinocytosis. This predicts cell survival of cultured stomach tumor cells as a function of L1AG concentration.
12645005 plays a prominent role in leukocyte trafficking and arachidonic acid metabolism; elevated levels of S100A9 and S100A8 in body fluids of inflamed tissues strengthen the view that these molecules are important players in fighting inflammation [review]
12137245 These data indicate that calprotectin (MRP8 and MRP14) has higher specific activity to induce apoptosis than the individual subunits, and that the mechanism is exclusion of zinc from target cells.
