After completing his MSc in Medical Biotechnology at the University of Bologna, Dr Saponaro joined the IFOM-IEO Campus in Milan for his PhD in the Foiani group. During this period, he characterised the role the CDK1 dependent phosphorylation of Srs2, finding that it was specifically required to promote homologous recombination in response to double strand break repair. Towards the end of this period Dr Saponaro developed also an interest for transcription-associated genome instability that let him to join the Svejstrup group in Clare Hall (CRUK-London Research Institute). Here he got in particular interested in the interaction between the RNA Pol II and RECQL5, finding that RECQL5 controls the elongation rate of the RNA Pol II, reducing in this way pausing/stalling instances (transcription stress) of the RNA Pol II. These transcription stress sites turn out to be particularly detrimental for the cells, because these sites overlap with the sites of genome instability arising without RECQL5. In this way he proved how mechanistically RECQL5 roles in controlling transcription progression are connected to its roles in preserving genome stability.

After his postdoc in London he decided to move to Birmingham to establish his own lab after being awarded a Birmingham Fellowship. The lab focuses on the characterising how transcription-associated factors promote RNA Pol II transcription and how their role is fundamental to preserve genome stability. He has also a clear interest in understanding the impact of the deregulation of transcription-associated factors in human health (in particular in cancer) and in identifying approaches to exploit these conditions for therapeutic purposes.

Throughout his research career, Dr Saponaro has focused on studying and characterising genome stability maintenance, using several biological systems and techniques. During his PhD in the Foiani lab he characterised the relevance of the CDK1-dependent phosphorylation of the DNA helicase Srs2, discovering that Srs2 is one of the first identified targets of CDK1 in the double strand break repair in S. cerevisiae. He has also been involved in the characterisation of the role of Sen1 (homolog of SETX, mutated in the neurodegenerative disorders AOA2 and ALS4) in genome stability maintenance and in its role in coordinating transcription and replication.

After being appointed as a Birmingham Fellow he has expanded and developed his research interests. In particular, he is characterising how and why RNA Pol II transcription can become source of genomic stress, implementing and expanding the genome wide approaches he currently uses. The interface between transcription and genomic instability in higher eukaryotes is an emerging field, with many open questions. The research program will aim not only to describe a phenotype, but also to understand the mechanism behind it. These studies will help clarifying how the two biological fundamental processes of transcription and replication can coexist, how they are coordinated and how they impact on each other. This is not only a fundamental biological problem but has clear implications for human health.
