Abstract:
The molecular mechanisms behind Dengue virus-dependent host pathogenesis, especially genome instability, remain largely unclear. This RNA virus causes a debilitating disease during active infection and presents future risks of postdengue syndromes, leukemia, and DNA damage in the blood cells of infected patients, with the underlying mechanisms unknown. In this study, we show that DENV-4 infection induces significant DNA damage and suppresses the transcription of genes involved in DNA repair and select mutagenic translesion synthesis (TLS) polymerases, indicating that DENV-4-dependent pathobiology leaves durable biological "scars" that incrementally increase chronic disease risk, including carcinogenesis and postdengue syndromes.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
