Dinoprostone 54-58 insulin like growth factor 1 Homo sapiens 70-98 16257278-4 2006 A linear relationship was observed between endogenous PGE2 levels and insulin-like growth factor 1 (IGF-1) levels in OA Ob. Dinoprostone 54-58 insulin like growth factor 1 Homo sapiens 100-105 16257278-5 2006 As parathyroid hormone (PTH) and PGE2 are known stimulators of IGF-1 production in Ob, we next evaluated their effect in OA Ob. Dinoprostone 33-37 insulin like growth factor 1 Homo sapiens 63-68 16257278-6 2006 Both subgroups increased their IGF-1 production similarly in response to PGE2, while the high OA subgroup showed a blunted response to PTH compared to the low OA group. Dinoprostone 73-77 insulin like growth factor 1 Homo sapiens 31-36 16257278-7 2006 Conversely, only the high OA group showed a significant inhibition of IGF-1 production when PGE2 synthesis was reduced with Naproxen, a non-steroidal antiinflammatory drug (NSAID) that inhibits cyclooxygenases (COX). Dinoprostone 92-96 insulin like growth factor 1 Homo sapiens 70-75 16257278-8 2006 The PGE2-dependent stimulation of IGF-1 synthesis was due in part to the cAMP/protein kinase A pathway since both the direct inhibition of this pathway with H-89 and the inhibition of EP2 or EP4 receptors, linked to cAMP production, reduced IGF-1 synthesis. Dinoprostone 4-8 insulin like growth factor 1 Homo sapiens 34-39 16257278-8 2006 The PGE2-dependent stimulation of IGF-1 synthesis was due in part to the cAMP/protein kinase A pathway since both the direct inhibition of this pathway with H-89 and the inhibition of EP2 or EP4 receptors, linked to cAMP production, reduced IGF-1 synthesis. Dinoprostone 4-8 insulin like growth factor 1 Homo sapiens 241-246 16257278-10 2006 Under basal condition, OA Ob expressed similar IGF-1 mRNA to normal Ob; however, PGE2 stimulated IGF-1 mRNA expression more in OA than normal Ob. Dinoprostone 81-85 insulin like growth factor 1 Homo sapiens 97-102 16257278-11 2006 These data suggest that increased IGF-1 levels correlate with elevated endogenous PGE2 levels in OA Ob and that higher IGF-1 levels in OA Ob could be important for bone sclerosis in OA.
