摘要采用不同培养细胞系研究了1-烷基-2-乙酰-sn-甘油-3-磷酸胆碱(血小板活化因子)的代谢。所有的培养都是在牛血清白蛋白和无血清培养基中进行的,因为白蛋白消除了1-烷基-2-乙酰- asn -甘油-3-磷酸胆碱对培养皿的吸附和血清酶的干扰。人类白血病(HL-60)细胞、MDCK犬肾细胞以及转化和非转化的小鼠c3h101 /2细胞克隆对1-烷基-2-乙酰- cn -甘油-3-磷酸胆碱的摄取、降解和再酰化能力表现出不同的速率。HL-60细胞摄取率最高(24.6 pmol/mg细胞蛋白/15 min)。尽管培养中的C3H10T1/2细胞的摄取率与其他测试细胞相当,但它们对1-烷基-2-乙酰-sn-甘油-3-磷酸胆碱表现出相对的代谢惰性。
Abstract The metabolism of 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine (platelet-activating factor) was studied using various cultured cell lines. All incubations were done in the presence of bovine serum albumin and serum-free media, since albumin eliminates the adsorption of 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine to cultureware and serum enzymes interfere. Human leukemia (HL-60) cells, MDCK canine kidney cells, and transformed and nontransformed clones of mouse C3H1OT1/2 cells display varying rates of uptake, degradation, and capacities for reacylation of 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine. HL-60 cells displayed the highest uptake rate (24.6 pmol/mg cell protein/15 min). Whereas C3H10T1/2 cells in culture showed uptake rates comparable to other cells tested, they displayed a relative metabolic inertness towards 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine.
