| 背景说明 | Eicosapentaenoic Acid是一种ω-3脂肪酸,具有多种生物学活性。 |
| 生物活性 | Eicosapentaenoic Acid (EPA) is an orally active Omega-3 long-chain polyunsaturated fatty acid (ω-3 LC-PUFA). Eicosapentaenoic Acid exhibits a DNA demethylating action that promotes the re-expression of the tumor suppressor gene CCAAT/enhancer-binding protein δ (C/EBPδ). Eicosapentaenoic Acid activates RAS/ERK/C/EBPβ pathway through H-Ras intron 1 CpG island demethylation in U937 leukemia cells. Eicosapentaenoic Acid can promote relaxation of vascular smooth muscle cells and vasodilation[1-3]. |
| In Vitro | Eicosapentaenoic Acid (100 μM; 1, 3, 24 h) causes a significant increase of H-Ras and N-Ras mRNA levels conditioning for 1 and 3 hours. K-Ras mRNA levels were not affected by Eicosapentaenoic Acid[1]. |
| In Vivo | Daily gavage of ω-3 PUFAs (300 mg docosahexaenoic acid [DHA] plus 60 mg eicosapentaenoic acid [EPA]) significantly attenuated the development of form deprivation myopia in guinea pigs and mice, as well as of lens-induced myopia in guinea pigs. Additionally, treatment with EPA antagonized hypoxia-induced myofibroblast transdifferentiation in cultured human scleral fibroblasts.[2] |
| 动物实验 | After one week of acclimatization with free access to standard mouse chow (commercial diet, 17.14% of energy from fat, 5.05 g/100 g) and water, the mice were randomly divided into nine groups each containing six mice and fed ALA series diets (1, 2.5, 5, or 7.5 wt%), 5% ALA and EPA series diets (0.25, 0.5, 1 wt%), EPA diet (2 wt%), or the control diet (Ctl diet: depleted in ω-3 PUFA) for seven weeks.[3] |

它们是不科学的。比如,我们常常把胆固醇作为一种有害健康的物质看待,但胆固醇是合成胆汁、肾上腺皮质激素、性激素和维生素D的重要物质,只有在过量时才会对人体造成伤害;而我们认为DHA(二十二碳六烯酸)、EPA(二十碳五烯酸)有利于降低血脂,但摄入过量同样存在危险。因此,只有合理、均衡地摄入各种脂肪酸,才是健康的保证。合理、均衡地摄入脂肪酸主要是指膳食脂肪酸中饱和脂肪酸、单不饱和脂肪酸、多不饱和脂肪酸三者比例要适当,而且多不饱和脂肪酸中的n-6系与n-3系脂肪酸的比例也要适当。 人们摄入脂肪酸的途径主要
