Comparative Oncogenomics of Liver Disease: the Sex Matters
Comparative Oncogenomics of Liver Disease: the Sex Matters
Damjana Rozman, PhD, University of Ljubljana, Faculty of Medicine, Slovenia
It is largely accepted that female and male liver metabolism differ substantially. Over 1,000 hepatic genes differ in their sex dependent expression and the multifactorial liver pathologies usually prevail in one or the other sex. It is thus surprising that little research is focused on understanding the molecular causes behind the sexual dimorphic liver pathologies. In our work we developed a mouse model with diminished cholesterol synthesis due to a knock-out in a cholesterol synthesis gene Cyp51. These mice present with nonalcoholic hepatitis that finally results in the female prevalent hepatocellular carcinoma (HCC). By integrative analyses of the mouse HCC transcriptomes and the human HCC transcriptomes from public databases, we identified the disbalanced cholesterol metabolism as one of the risk factors for sex-dependent devastating liver damage. Females were more affected and have a more aggravating disease phenotype. These findings are novel since most literature data suggest that (a) increased cholesterol is linked to the progressive liver disease; (b) HCC is a male prevalent disease. It is now clear that in addition to common variants in the genes, such as PNPLA3 and TM6SF2, some rare or even private mutations can contribute to liver pathologies, and that the incidence of HCC in females raises sharply after the menopause.
In conclusion, we identified a subgroup of liver pathologies with more aggravating phenotype in the females. These findings open new venues towards more personalized approach for liver disease intervention strategies, where we might search for different targets in females and males.
