jessica zucman rossiGenomics of human hepatocellular carcinoma: mechanism of malignant transformation, signature of risk factors and therapeutic targets
Jessica Zucman-Rossi, MD, PhD, Professor of Oncology, University Paris Descartes, Director of the Inserm Unit “Functional Genomic of Solid Tumors”, UMRS-1162, Paris, France

Prof. Zucman-Rossi’s group has pioneered in the elucidation of the molecular classification of benign and malignant liver tumors. Prof. Zucman-Rossi leads the French liver tumor project in the International Cancer Genome Consortium (ICGC). Currently, she is chairman of the scientific committee “Genetic, Epigenetic and Cancer” at Inserm, member of the ILCA (International Liver Cancer Association) governing board and future executive secretary (2015-2018), she acts as co-Editor for Journal of Hepatology.
Hepatocellular carcinoma (HCC) is one of the leading causes of death by cancer worldwide. It is mainly developed on cirrhosis due to chronic hepatitis B and C, metabolic and alcoholic liver diseases in western countries. In contrast, hepatocellular adenomas are rare benign liver tumors frequently developed in women after oral contraception. Recent advances in molecular classification and dissection of genetic and epigenetic drivers have increased our knowledge of the molecular diversity of benign and malignant liver tumors. Using genomic approaches, we identified several new oncogenes and tumor suppressor genes and we described a molecular classification of hepatocellular adenomas that is used in clinical routine. Recently, using sequencing, we identified TERT promoter mutations activating telomerase as the most important mechanism of malignant transformation of both adenoma in carcinoma and of cirrhotic nodules in carcinoma. We also found new etiological factors predisposing to liver tumor development and new drug targets.
