Rat brain protein kinase C (PKC) isozymes I, II and III were stimulated by fatty acids in the absence and presence of calcium. Ethyl oleate, which by itself has no effect on PKC activity, had a potentiating effect on fatty acid-induced activation of all 3 isozymes. Potentiation was observed predominantly in the presence of calcium. Interaction of ethyl oleate with a signalling mechanism involving PKC may underlie the cognitive disturbances noted after alcohol consumption.
在有钙和无钙的情况下，大鼠脑蛋白激酶C（PKC）同工酶I、II和III均受到脂肪酸的刺激。油酸乙酯本身对PKC活性没有影响，但对脂肪酸诱导的所有3种同工酶的激活具有增强作用。这种增强作用主要在有钙的情况下观察到。油酸乙酯与涉及PKC的信号传导机制之间的相互作用可能是饮酒后出现认知障碍的基础。
