Abstract:
BACKGROUND:The aim of the present study was to evaluate the effect of a moderate diet restriction on the progression of preneoplastic foci into hepatocellular carcinomas (HCCs) and whether such an effect was related to altered cell proliferation, apoptosis, and/or tumour contents of lipid-soluble antioxidants. METHODS:Male Wistar rats were exposed to diethylnitrosamine as initiator and 2-acetylaminofluorene plus partial hepatectomy as promoter. Six weeks after initiation the animals were given a diet restricted to 75%-80% of that given to controls until being killed 45 weeks later. Macroscopic liver tumours were histologically classified. In hepatocellular carcinomas the numbers of S-phase (labelling index) and DNA-fragmented (apoptotic index) nuclei were calculated immunohistochemically, and the tumour contents of alpha-tocopherol and ubiquinone were determined. RESULTS:The number of animals with HCC and the number of HCCs per animal were significantly reduced in restricted-diet animals compared with controls. In HCCs the contents of ubiquinone-9 and -10 were significantly increased, labelling indices were enhanced 3-fold, and apoptotic indices 12-fold as a response to food restriction. Neither the size nor the differentiation of HCCs was altered by food restriction. The numbers and areas of preneoplastic foci were similar in restricted-diet animals compared with those of controls. CONCLUSION:Moderate, long-term food restriction inhibits the progression of preneoplastic liver foci into HCC. Possible mechanisms of this inhibition are a shift in the balance between apoptosis and cell division towards cell death and an adaptive response to oxidative stress by increased tumour contents of ubiquinones.
