tumor suppressor genes - ️️A gene whose protein product inhibits cell division, thereby preventing the uncontrolled cell growth that contributes to cancer (P53, proapoptotic genes). Hallmarks of Cancer - ️️1. Sustaining proliferative signaling 2. Evading growth suppressors 3. Activating invasion and metastasis 4. Enabling replicative immortality 5. Inducing angiogenesis (developing blood supply) 6. Resisting cell death (apoptosis) tumor (neoplasm) - ️️mass of rapidly dividing...

Apoptosis - correct answer-Cells of a neoplasm do not die off like normal cells so the number of cells grows, rather than remain constant as in healthy tissue. Labile Cell - correct answer-Cells of tissue that continuously divide and replicate throughout life. Ex: epithelial cells of skin, oral cavity, vagina, cervix, GI tract, and bone marrow. Permanent Cell - correct answer-Cells of tissue that do not proliferate. Ex: nerve cells, skeletal muscle cells, and cardiac muscle cells. Stabl...
