摘要

AbstractWe examined expression of the c‐myc oncogene in isolated perfused livers to elucidate the mechanisms involved in triggering the proliferation of hepatocytes after partial hepatectomy (PH). During perfusion with a 1:1 mixture of Dulbecco's modified Eagle's medium and the oxygen transport fluid FC‐43, rat livers were two‐thirds resected (PH), and further perfused for 1 1/2 hours at the physiological portal flow throughout the perfusion. Expression of c‐myc in the perfused livers with PH(+) was ten times higher than in those with PH(−). Furthermore, expression of c‐myc in the PH(−) livers perfused with a threefold volume of the physiological portal flow was 5–10 times higher than that in the livers perfused with the physiological portal flow. The perfusates that passed through the livers did not induce DNA synthesis of primary cultured hepatocytes. These results suggest that an increase in the portal flow volume may act as a trigger for hepatocyte proliferation after PH. © 1993
