Cobalt 13-19 erythropoietin Mus musculus 49-63 163577-3 1975 In addition, cobalt increases the activity of an erythropoietin-generating enzyme (renal erythropoietic factor) with maximal enzyme activity occurring after the rise in cyclic AMP levels but before the increase in erythropoietin titers. Cobalt 13-19 erythropoietin Mus musculus 214-228 163577-9 1975 These results suggest that cyclic AMP plays a significant role in the renal production of erythropoietin following cobalt administration. Cobalt 115-121 erythropoietin Mus musculus 90-104
