The interactive potential of three known peroxisome proliferators, omega-3 fatty acids, clofibrate and di(2-ethylhexylphthalate (DEHP), was evaluated in male weanling Wistar rats for the effect on peroxisomal beta-oxidation. Omega-3 fatty acids were supplied by menhaden oil which was fed in six regimens: low fat (5% w/w), low fat and clofibrate (0.3% w/w) or DEHP (0.25% w/w), high fat (20% w/w), high fat and clofibrate or DEHP in the aforementioned concentrations. Induction of peroxisomal beta-oxidation was measured by changes in liver-to-body weight ratio, fatty acyl-CoA oxidase (FAO) activity, and peroxisomal bifunctional enzyme (PBE) quantity. Analysis of transformed data indicated a less than additive response in FAO activity with no deviation from additivity seen with liver-to-body ratios and PBE.
在雄性断乳Wistar大鼠中评估了三种已知的过氧化物酶体增殖剂(ω-3脂肪酸、氯贝丁酯和邻苯二甲酸二(2-乙基己基)酯(DEHP))对过氧化物酶体β-氧化作用的交互潜力。ω-3脂肪酸由Menhaden油提供,以六种方案喂食:低脂(5% w/w)、低脂加氯贝丁酯(0.3% w/w)或DEHP(0.25% w/w)、高脂(20% w/w)、高脂加上述浓度的氯贝丁酯或DEHP。通过肝体重比、脂肪酰基辅酶A氧化酶(FAO)活性和过氧化物酶体双功能酶(PBE)数量的变化来测量过氧化物酶体β-氧化的诱导情况。对转换后数据的分析表明,FAO活性的反应小于相加性,而肝体重比和PBE未出现偏离相加性的情况。
