10hallmarks Flashcards
Sustaining Proliferative Signaling
Cancer cells continuously signal themselves or nearby cells to promote growth.
Evading Growth Suppressors
Cancer cells avoid growth inhibitors like p53 and RB, allowing uncontrolled cell division.
Resisting Cell Death (Apoptosis)
Cancer cells evade apoptosis by overexpressing anti-apoptotic proteins or avoiding pro-apoptotic signals.
Enabling Replicative Immortality
Cancer cells activate telomerase to maintain telomere length, allowing cells to divide indefinitely.
Inducing Angiogenesis
Cancer cells secrete VEGF and other factors to stimulate the growth of blood vessels, supplying the tumor with nutrients and oxygen.
Activating Invasion and Metastasis
Cancer cells can break through tissue barriers, enter blood vessels, and spread to distant parts of the body.
Deregulating Cellular Energetics
Cancer cells alter their metabolism (e.g., the Warburg effect) to provide energy and building blocks for fast proliferation.
Avoiding Immune Destruction
Cancer cells can express immune checkpoint proteins like PD-L1, suppressing immune responses and evading immune surveillance.
Genome Instability and Mutation
Cancer cells often have defects in DNA repair, leading to increased mutations and genetic instability, which drives tumor progression.
Tumor-Promoting Inflammation
Chronic inflammation in the tumor microenvironment promotes growth, survival, and metastasis of cancer cells.
