The Genomics Evolutionary of Cancer-Associated Pathogens

The genomic evolution of pathogens associated with cancer in humans represents a fascinating yet underexplored area in evolutionary research. In this chapter, we will elucidate how a complex eco-evolutionary interaction unfolds between hosts and pathogens. Additionally, we provide a comprehensive exploration and holistic overview of the evolutionary genomics of various pathogens, including viruses and bacteria, that contribute to the etiology of type cancers. This research aims to uncover how these pathogens have adapted and evolved at the genomic level, enabling them not only to survive within the human host but also to contribute to carcinogenesis. The chapter introduces the reader to major cancer-associated pathogens, such as the human papillomavirus (HPV), hepatitis B and C viruses (HBV and HCV), Epstein-Barr virus (EBV), and Helicobacter pylori (H. pylori). We explore the evolutionary mechanisms of these pathogens, such as mutation, recombination, and gene transfer, which enhance their oncogenic capacity. Understanding the coevolutionary dynamics between pathogens and their human hosts is crucial, as well as how evolutionary forces drive adaptation in diverse ecological niches to induce cancer. Omics tools help deepen our understanding of their role in evolution, leading to better outcomes and advancements in the fight against cancer.
