Cell membrane disruption by high alkalinity

High alkalinity—elevated extracellular pH—can cause significant disruption to the structure and function of cell membranes across various organisms. This disruption is primarily characterized by increased membrane permeability and ion leakage due to lipid peroxidation, which is driven by excessive production of reactive oxygen species (ROS) and oxidative stress. The resulting membrane instability leads to cell death, reduces tissue viability, and can negatively affect physiological processes such as growth in plants or homeostasis in bacteria. Since "cell membrane disruption by high alkalinity" is an injury mechanism rather than a molecular target, it is not considered a canonical therapeutic target or classified within known gene/protein families, and thus directly targeting this process pharmacologically is not feasible. Instead, some studies focus on mitigating membrane damage through antioxidants or environmental modifications. This entry is not a canonical target and should be corrected to reference specific molecular components affected by high alkalinity (for example, plasma membrane oxidized phospholipids, or specific ion channels modulated under alkaline stress).
