Osteostatin
Osteostatin, a fragment of parathyroid hormone-related protein (PTHrP) 107-111, promotes bone repair in animal models of bone defects and prevents bone erosion in inflammatory arthritis, inhibits collagen-induced arthritis and inhibits osteoclastic bone resorption directly. Osteostatin can be used for inflammation and immunology research.

Biologische Aktivität
Osteostatin (100, 250 and 500 nM, 7-9 days) decreases the differentiation of osteoclasts in a concentration-dependent manner[2].
Osteostatin (100, 250 and 500 nM, 7 days) decreases the mRNA levels of cathepsin K, osteoclast associated Ig-like receptor (OSCAR) and NFATc1[2].
Osteostatin (100, 250 and 500 nM, 2 days) inhibits the nuclear translocation of the master transcription factor NFATc1 in osteoclast differentiation [2].
Osteostatin (0.1-100 nM, 2 days) significantly increased cell growth in MC3T3-E1 cells[3].

-
Animal Model:Collagen-induced arthritis in male DBA/1 mice[4]
-
Dosage:80 or 120 μg/kg
-
Administration:After the onset of disease s.c. every day for 13 days
-
Result:Reduced serum IgG2a levels as well as T cell activation, with the downregulation of RORγt+CD4+ T cells and upregulation of FoxP3+CD8+ T cells in lymph nodes.
Decreased the levels of key cytokines, such as interleukin (IL)-1β, IL-2, IL-6, IL-17, and tumor necrosis factor-α in mice paws, whereas enhanced IL-10.
