Summary Hallmarks of cancer - Mindmap

This document, titled “Hallmarks of Cancer”, provides a comprehensive overview of the key biological traits and mechanisms that define cancer development, progression, and survival. It elaborates on the foundational principles outlined in the widely recognized “Hallmarks of Cancer” framework, originally proposed by Hanahan and Weinberg, and expands upon its core, enabling, and emerging concepts. Content Highlights: 1. Core Hallmarks of Cancer: • Sustaining Proliferative Signaling: Describes how cancer cells bypass normal growth controls through mutations and overexpression of growth factors. • Evading Growth Suppressors: Explains the inactivation of tumor suppressor genes like TP53 and RB, leading to unchecked cellular growth. • Resisting Cell Death: Details mechanisms such as BCL-2 mutations that prevent apoptosis, allowing cancer cells to survive despite damage. • Enabling Replicative Immortality: Discusses telomerase reactivation and its role in cellular immortality. • Inducing Angiogenesis: Covers the release of VEGF and the formation of new blood vessels to sustain tumor growth. • Activating Invasion and Metastasis: Highlights how cancer cells spread to distant organs via tissue barriers and the circulatory system. 2. Enabling Characteristics: • Genome Instability and Mutation: Focuses on the genetic diversity resulting from high mutation rates, aiding cancer survival and therapy resistance. • Tumor-Promoting Inflammation: Examines how chronic inflammation supports tumor growth and damages DNA through reactive oxygen species. 3. Emerging Concepts: • Deregulating Cellular Metabolism: Explains the Warburg effect, where cancer cells favor glycolysis for energy production. • Avoiding Immune Destruction: Describes immune evasion tactics, including PD-L1 expression and immune checkpoint molecule regulation. • Unlocking Phenotypic Plasticity: Discusses how cancer cells adapt through dedifferentiation and transdifferentiation. • Nonmutational Epigenetic Reprogramming: Covers changes in gene expression through DNA methylation and histone modification. • Polymorphic Microbiomes: Investigates the influence of microbiota on immune responses and therapy outcomes. • Role of Senescent Cells: Explores the dual role of senescent cells in both preventing and promoting cancer. This document serves as a valuable resource for students, researchers, and professionals seeking to understand the intricate biology of cancer. It is written in a clear and concise manner, making it suitable for educational and reference purposes. The inclusion of both established and emerging concepts ensures a well-rounded perspective on cancer biology.
