生化／生理作用
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 。

Definitive haematopoiesis occurs during the lifetime of an individual, which continuously replenishes all blood and immune cells. During embryonic development, haematopoietic stem cell (HSC) formation is tightly controlled by growth factors, signalling molecules and transcription factors. But little is known
