Aquaporin Expression

Meaning

Aquaporin expression denotes the biological process of synthesizing and regulating the quantity and location of aquaporin proteins within cell membranes. These proteins function as highly selective channels that facilitate the rapid transport of water across cellular barriers, a process essential for maintaining cellular volume and fluid balance. Proper aquaporin regulation is fundamental to the physiological function of numerous organs, including the kidneys, salivary glands, and skin. In a clinical setting, understanding this expression level provides insight into the efficiency of water handling and hydration status at the cellular level.
