The present studies were undertaken to assess the direct effects of N6-cyclohexyladenosine (CHA), a stable adenosine analogue, on erythropoietin (Ep) secretion in hepatocellular carcinoma cells (Hep 3B). Ep levels in the medium of low density Hep 3B cells treated with CHA in concentrations of 10(-5) and 5 x 10(-5) M for 20 h under hypoxic conditions (1% O2) were significantly higher than that of hypoxic controls. In addition, CHA at the same concentrations produced significant increases in adenosine 3',5'-cyclic monophosphate (cAMP) levels in Hep 3B cells after 1-h incubation under hypoxic conditions when compared with hypoxic controls. Dibutyryl cAMP (10(-5), 10(-4) M) also caused significant increases in Ep secretion when compared with control hypoxic cells. On the other hand, 8-phenyltheophylline, an adenosine receptor antagonist, significantly inhibited the stimulatory effects of CHA on both Ep secretion and cAMP accumulation in the Hep 3B cell cultures in response to hypoxia. These data suggest that Ep secretion may be regulated by adenosine receptor-coupled activation of adenylyl cyclase and the generation of cAMP.
