Stéphane Bertani is a molecular biologist and epigenetician. Since 2011, he has focused his work on the role of hom-lncRNAs in cancer, notably HCC. He initiated coaction with Dr Eloy Ruiz, a Peruvian surgeon specialized in gastroenterology at the Peruvian institute for cancer (INEN) and created a team specialized in the study of HCC at INEN. He showed that the burden of cancer in Peru appears to particularly afflict socially vulnerable populations, such as women and remote, deprived people. He is also conducting geographical correlation studies to identify environmental determining factors for cancer amongst the Peruvian population.
