Proteostasis and Cancer explores the intricate mechanisms of protein homeostasis and their critical roles in cancer progression and therapeutics. The book delves into the mechanisms that control proteins inside the cell to preserve the health of the cellular proteome and the organism itself. It covers key topics such as post-translational modifications, protein folding, proteolysis, and the unfolded protein response (UPR), with a specific focus on their roles in cancer. Detailed discussions on molecular chaperones, the ubiquitin-proteasome system, and autophagy pathways offer valuable insights into how these processes contribute to cancer progression and how they can be targeted for therapeutic interventions. With clear explanations and well-labeled diagrams, the book makes complex concepts accessible to students and researchers alike. It also addresses the clinical implications of proteostasis in cancer, providing a foundation for developing innovative, therapeutic strategies. The book's multidisciplinary approach, combining insights from biochemistry, cancer biology, and medical sciences make it an essential resource for anyone seeking to understand the role of proteostasis in cancer.
