Prof. Gianluca Tell Biosketch

A.         Personal Statement

The field of Prof Tell prevailing interests is the study of molecular mechanisms of gene expression particularly in the field of redox signalling and cell oxidative stress. Now, he is focusing on some aspects linking gene expression and DNA repair and its relevance in molecular oncology and cancer.

In particular, from 1998, he contributed to the understanding of the molecular mechanisms involving the main mammalian Apurinic/Apyrimidinic Endonuclease APE1 in coordinating cellular responses to oxidative stress in different cell models. His background includes molecular and cellular biology as well as biochemistry techniques to characterize the relationship between structure and function of proteins involved in gene expression and DNA repair. He coordinated several research projects granted from Telethon, AIRC, PRIN, ASI and worked as a Referee for 20 different International Journals (Oncogene, Nucleic Acids Research, Proteomics, Cancer Research, etc).
