← Human Body & HealthA drug aims to inhibit EGFR (Epidermal Growth Factor Receptor) in lung cancer cells. If this drug's delivery is inconsistent, which consequence follows regarding the cancer cell cycle?
A)Uncontrolled cell cycle arrest occurs
B)Accelerated mitotic checkpoint activation results
C)Increased reliance on anaerobic metabolism develops
D)Aneuploidy via mitotic slippage becomes likely✓
💡 Explanation
Inconsistent EGFR inhibition leads to unsynchronized cell cycle progression. Because the mitotic checkpoint is weakened, cells can escape mitosis despite DNA errors (mitotic slippage). Therefore, aneuploidy, characterized by abnormal chromosome numbers, becomes likely, rather than controlled arrest, accelerated activation, or changes in metabolism.
