Nutrient Deprivation Signaling

Meaning

Nutrient Deprivation Signaling refers to the intricate molecular pathways that become activated within a cell when essential macronutrients, such as glucose or amino acids, are scarce. This signaling cascade serves as a critical survival mechanism, prompting the cell to conserve energy, halt growth, and initiate catabolic processes like autophagy to recycle internal components for fuel and building blocks. It is a fundamental link between metabolic state and cellular longevity.
