| pubmed-article:1311742 | pubmed:abstractText | This study reports the effects of cyclic adenosine 3'-5' monophosphate (cAMP) and hypoxia on erythropoietin biosynthesis in an erythropoietin-producing hepatocellular carcinoma cell line (Hep3B). Erythropoietin levels in the medium and cell extracts of low-density Hep3B cells after 20-hour incubation under hypoxic conditions (1% O2) were 25.33 +/- 1.50 mU/ml/10(7) cells and 3.60 +/- 0.50 mU/10(7) cells, respectively. These levels were significantly higher than in the respective normoxic controls (medium, 2.51 +/- 0.31 mU/ml/10(7) cells; cell extracts, undetectable [less than 0.31 mU/10(7) cells]). Cobalt also produced a significant increase in medium and cell erythropoietin levels. However, hypoxia and cobalt alone failed to produce an increase in cAMP accumulation in the cell cultures. Erythropoietin levels in the medium and cell extracts from cells exposed to 8-bromo cAMP (1 x 10(-4) mol/L) and forskolin (4 x 10(-6) mol/L) in a hypoxic atmosphere were significantly (p less than 0.05) higher than in the respective hypoxic controls. In addition, forskolin produced a significant (p less than 0.05) increase in cAMP accumulation (180 +/- 11.5 pmol/10(6) cells) under hypoxic conditions compared with the hypoxic controls (cAMP, 2.27 +/- 0.33 pmol/10(6) cells). These results suggest that cAMP elevation is not required in vitro in Hep3B cells for the increase in medium and cell levels of erythropoietin after hypoxia, but may be involved indirectly in erythropoietin biosynthesis, secretion, or both in vivo through some synergistic action with hypoxia. | lld:pubmed |
