Cellular Adaptation to Stress

Meaning

Cellular Adaptation to Stress describes the intrinsic, dynamic capacity of individual cells to alter their gene expression, protein synthesis, and metabolic pathways in response to persistent or overwhelming environmental and physiological demands. This process is a fundamental survival mechanism, allowing cells to maintain viability and function despite challenging conditions like oxidative stress, nutrient deprivation, or hormonal overload. Successful adaptation ensures tissue homeostasis and contributes significantly to overall organismal resilience and longevity. Failure to adapt effectively leads to cellular dysfunction, senescence, and ultimately, tissue pathology.
