Outline of Final Research Achievements |
Earlier reports have shown a high prevalence of hepatitis C virus (HCV) infection in patients with PCT. While these observations implicate HCV infection as a risk factor for PCT pathogenesis, the mechanism of interaction between the virus and porphyrin metabolism is unknown. Here, we showed that HCV core protein triggers abnormal porphyrin metabolism, expressed by excess coproporphyrin excretion and higher porphyrins synthesis rate, via the change in the expression of enzymes and transporters involved in heme synthesis pathway. In addition, we confirmed that HCV core protein strengthen the ethanol-induced increase in ALAS1 protein expression that is a rate-limiting enzyme in heme synthesis.
