"Apoptosis, Senescence and Cancer" offers a comprehensive analysis of established practices and current research on apoptosis and senescence. The book thoroughly examines novel and emerging techniques in areas such as cell death pathways, growth arrest due to senescence, drug resistance, DNA damage response, and other topics that remain puzzling for researchers. The structure of the book is divided into six clearly organized sections, making it easier for readers to grasp the content. The chapters cover a wide range of topics, from alternative modes of cell death to telomeres and telomerase, as well as genomic instability and tumorigenesis. Additionally, DNA damage responses, signaling pathways, and the challenges of resistance and sensitization are addressed. The final part of the book focuses on established and newly developed cancer therapies, providing insights into future developments in cancer research. This work is aimed at both basic scientists and clinicians, offering a deeper understanding of cellular responses to malignancies that can influence the effectiveness of treatments.
