Francesca Forno, ESR9 of ITN TREATMENT, was talking about her poster presentation with the Nobel Prize Roger Kornberg in The 25th advanced school in life sciences on signal transduction in Jerusalem. The Poster entitled Cellular responses of hepatocytes to anti-schizophrenic drugs linked to obesity is also signed by Ángela M. Valverde and Boaz Tirosh. Roger Kornberg succeeded in mapping the process by studying yeast in the first decade of the new millennium. His contributions included determining the structure of the enzyme active in the process – RNA polymerase – and creating images of how the RNA molecule is constructed.
