Biomolecular, Genomic and Bioinformatic Sciences Unit

Research at the Biomolecular, Genomic and Bioinformatic Sciences Unit (USBGB) is centered on the interdisciplinary field of Genomics. It includes Biochemistry, Molecular and Cell Biology, Genetics, Microbiology, Bioinformatics and Biostatistics as the main reference scientific disciplines.

The studies conducted by USBGB members range from Functional and Structural Genomics, including Evolutionary Genomics and Phylogenomics, to Systems Biology – an increasingly growing research area that combines all the most modern aspects of contemporary Biology, Molecular and Cellular Biotechnologies and Biomedicine, often with highly relevant applied implications and translational potential.

The research activity of the USBGB conjugates basic biological studies with more applied investigations in the fields of human health and biotechnology. Regarding basic biological research, most studies leverage model organisms in order to achieve an in-depth understanding of fundamental (and conserved) cellular processes, with the use of innovative bioinformatic, metagenomic, and molecular (e.g., transcriptomic) approaches. These touch upon all the main aspects of genetic information, including: genomes, genes and associated polymorphisms; gene expression (especially DNA transcription) and the regulatory processes (genetic and epigenetic) involved in its control; enzymes and structural proteins; also in relationship to cell/tissue functionality and its alteration under pathological conditions (e.g., chronic and/or degenerative diseases, neoplastic transformation and tumor progression, genotoxicity).

Special attention is paid to all the possible biomedical implications and translational potential of the basic research projects pursued by the USBGB, particularly with regard to the development and validation of novel recombinant HPV vaccines, synthetic single-chain antibody libraries, theranostic and immunotherapeutic agents; the discovery of specific protein-protein interaction inhibitors to be used as novel drugs (e.g., antibiotics) and the construction of innovative model systems aiding the study of important human (e.g., mitochondrial) pathologies and the identification of new small-molecule modifiers. Some research lines specifically related to ‘biotechnological innovation’ in the agro-food field are dedicated to the genetic improvement of industrial yeast strains, to the creation of novel probiotics and to the (bio)control of microbial toxins (e.g., aflatoxins).
