Application
花生四烯酸已用于:
- 在正常和乳腺癌样本中的拉曼光谱和原子力显微镜(AFM)中产生校准曲线
- 在耐药性分析中作为重组合成胆汁(RSB)的多不饱和脂肪酸补充剂
- 用于激活雷帕霉素1(mTOR1)和mTOR2的机制靶标
Biochem/physiol Actions
花生四烯酸 (AA) 是一种 ω6 不饱和脂肪酸,是细胞膜磷脂的组分。在炎症反应中,水解磷脂酶 A2 可将 AA 从膜磷脂中释放出来。然后,AA 可被至少两种环加氧酶 (COX) 亚型代谢为前列腺素和血栓烷,被脂氧合酶代谢为白三烯和脂氧素,以及通过细胞色素 p450 催化代谢为环氧-二十碳三烯酸。AA 及其代谢产物在多种生物过程中发挥着重要作用,包括信号转导、平滑肌收缩、趋化性、细胞增殖和分化,以及细胞凋亡。已证实 AA 可与 G 蛋白的亚基结合,抑制 Ras GTP 酶激活蛋白 (GAP) 的活性。AA 的细胞摄取需要消耗能量并涉及跨细胞质膜的蛋白质辅助运输。
花生四烯酸及其代谢产物在多种生物过程中发挥着重要作用,包括信号转导、平滑肌收缩、趋化性、细胞增殖和分化,以及细胞凋亡。
花生四烯酸可刺激MDA-MB-435人转移癌细胞与细胞外基质分子(胶原蛋白IV和玻连蛋白)的粘附 。
