important role in antitumor pathways, resulting in cancer cell death or restoring the disordered metabolism of cancer cells. The molecules generated during host stress responses to viruses can also contribute to the antitumor mechanisms in humans. However, the relationship between host stress responses to virus infection and tumorigenesis has not been extensively explored. In recent years, studies have shown that marine host stress responses to viral invasion can be good models for exploring human antitumor mechanisms. Stimulating further research in the field, this book offers graduate students and researchers with comprehensive insights into host stress responses to viral invasion and tumor progression. It is also a valuable resource for those working in the pharmaceutical industry interested in drug discovery based on molecules derived from host stress responses to viral infection.
