Bottom Line: The expression analysis of Fas and FasL genes was increasing during reperfusion (significantly in the group of 240 minutes of reperfusion).It was in the same group that apigenin decreased Fas receptor levels and inhibited apoptosis as confirmed by TUNEL assay and caspase 3 antibodies.The effects of apigenin in the Fas/FasL mediated pathway of apoptosis, in the hepatic ischemia-reperfusion, seem to have a protective result on the hepatic cell.

ABSTRACT

Background: The aim of this experimental study was to investigate the role of apigenin in liver apoptosis, in an experimental model of hepatic ischemia-reperfusion in rats.

Materials and methods: Forty-eight Wistar rats (apigenin and control groups), 14 to 16 weeks old and weighing 220 to 350 g, were used. They were all subjected to hepatic ischemia by occlusion of the hepatic artery and portal vein for 45 minutes and reperfusion was followed for 60, 120, and 240 minutes. Apigenin was administrated intraperitoneally. Liver tissues were used for the detection of apoptosis by TUNEL assay and caspase 3 antibodies. Expression analysis of Fas/FasL genes was evaluated by real time PCR.

Results: The expression analysis of Fas and FasL genes was increasing during reperfusion (significantly in the group of 240 minutes of reperfusion). It was in the same group that apigenin decreased Fas receptor levels and inhibited apoptosis as confirmed by TUNEL assay and caspase 3 antibodies.

Conclusions: The effects of apigenin in the Fas/FasL mediated pathway of apoptosis, in the hepatic ischemia-reperfusion, seem to have a protective result on the hepatic cell.

Levels of Fas protein in groups: (a) C60, C120, and C240; (b) AP60, AP120, and AP240; and (c) C60-AP60, C120-AP120, and C240-AP240.

Mentions: Consecutively, the Fas protein levels were compared among the control groups C60, C120, and C240 (Figure 3(a)), among the groups where apigenin was used AP60, AP120, and AP240 (Figure 3(b)), and finally, among the groups subjected to the same time of reperfusion, with and without the use of apigenin, that is, C60 versus A60, C120 versus AP120, and C240 versus AP240 (Figure 3(c)).
