Intracellular calcium concentration is increased, gap junctions are closed and cell volume is decreased after exposure to 5% ethanol. Since gap junctions are known to be calcium gated, it is likely that their closure is secondary to the elevated cytosolic calcium in ethanol injured cells. This may have a protective function by limiting intercellular spread of impending cell injury. The opening of the basolateral potassium channel probably underlies the ethanol-induced cell shrinkage and might contribute to the ethanol-provoked epithelial damage.
