人们普遍认为,富含鱼油的n-3多不饱和脂肪酸(PUFAs)可以预防多种心血管疾病,如心肌梗死、心律失常、动脉粥样硬化或高血压。二十碳五烯酸(EPA)和二十二碳六烯酸(DHA)可能是这些作用的活性生物成分。虽然这种有益作用的确切细胞和分子机制尚不清楚,但n-3 PUFAs的保护作用可归因于其对血管平滑肌细胞(VSMC)功能的直接作用。这些n-3 PUFAs激活K(+)(ATP)通道并抑制某些类型的Ca(2+)通道,可能通过至少两种不同的机制。N-3 PUFAs通过参与信号转导事件的调节机制,有利于改变类二十烷结构,并调节细胞因子诱导的诱导型一氧化氮合酶和环氧合酶-2的表达。N-3 PUFAs还可调节VSMC的增殖、迁移和凋亡。这些最近的数据表明,这些VSMC功能的调节有助于n-3 PUFAs对各种心血管疾病的有益作用。此外,最近的研究强烈表明,DHA比EPA具有更有效和有益的作用。然而,关于细胞和分子机制的许多问题仍有待解答。
It is widely accepted that n-3 polyunsaturated fatty acids (PUFAs) rich in fish oils protect against several types of cardiovascular diseases such as myocardial infarction, arrhythmia, atherosclerosis, or hypertension. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may be the active biological components of these effects. Although the precise cellular and molecular mechanisms underlying the beneficial effects are still uncertain, the protective effects of n-3 PUFAs are attributable to their direct effects on vascular smooth muscle cell (VSMC) functions. These n-3 PUFAs activate K(+)(ATP) channels and inhibit certain types of Ca(2+) channels, probably via at least 2 distinct mechanisms. N-3 PUFAs favorably alter the eicosanoid profile and regulate cytokine-induced expression of inducible nitric oxide synthase and cyclooxygenase-2 via mechanisms involving modulation of signaling transduction events. N-3 PUFAs also modulate VSMC proliferation, migration, and apoptosis. These recent data suggest that modulation of these VSMC functions contribute to the beneficial effects of n-3 PUFAs on various cardiovascular disorders. Furthermore, recent studies strongly suggest that DHA has more potent and beneficial effects than EPA. However, many questions about the cellular and molecular mechanisms still remain to be answered.
