Inhibition of angiotensinogen production by angiotensin II analogues in human hepatoma cell line.
    The American journal of physiology, 1989, Volume: 257, Issue:5 Pt 1

    The aim of this study was to examine in Hep G2, a human hepatoma-derived cell line, the presence of angiotensin II (ANG II) receptors and the effect of ANG II and its analogues on angiotensinogen production. The presence of ANG II receptors was demonstrated using a long-acting ANG II analogue, 125I-labeled [Sar1]ANG II. A single class of specific binding sites was identified in these cells with a dissociation constant (Kd) of 2 nM. The number and affinity of these binding sites were not changed by [Sar1]ANG II treatment over 24 h. ANG II showed an inhibitory effect on angiotensinogen production. [Sar1]ANG II also exhibited a similar inhibitory effect as that of ANG II but to a greater extent and therefore was used throughout these studies. [Sar1]ANG II inhibited angiotensinogen production in a dose-dependent manner, exhibiting a half-maximal inhibitory concentration (IC50) of 2 nM. Other ANG II analogues showed similar effects on angiotensinogen production. In order of decreasing ability, they were [Sar1]ANG II greater than [Sar1-Ala8]ANG II greater than [Sar1-Val8]ANG II greater than [Sar1-Val5-(Br5)-Phe8]ANG II greater than [Sar1-Val5-DPhe8]ANG II. Results of these studies show that the Hep G2 cell possesses specific ANG II receptors and that [Sar1]ANG II induces a dose-dependent inhibition of angiotensinogen production in this system.
