Tumour necrosis factor alpha (cachectin) was administered to virgin, lactating and litter-removed rats, and subsequent disposal of an oral [1-14C]triolein (glycerol tri[1-14C]oleate) load examined. Absorption of the lipid and 14CO2 production were significantly depressed in all three groups. [14C]Lipid accumulation was decreased in carcass, liver and adipose tissue (brown and white) of virgin and litter-removed rats and the mammary gland of lactating rats. The plasma triacylglycerol concentration was increased in all three groups, and lipoprotein lipase activity was decreased in the white adipose tissue of virgin and litter-removed animals and in the mammary gland of lactating animals. Some, but not all, of these effects mimic tumour burden in the same physiological states [Evans & Williamson (1988) Biochem. J. 252, 65-72].
将肿瘤坏死因子α(恶病质素)给予未生育、哺乳期和摘除幼崽的大鼠,并随后检测口服[1-¹⁴C]三油酸甘油酯(甘油三[1-¹⁴C]油酸酯)负荷后的处理情况。脂质的吸收和¹⁴CO₂的产生在所有三组中均显著降低。[¹⁴C]脂质在未生育和摘除幼崽大鼠的胴体、肝脏和脂肪组织(棕色和白色)以及哺乳期大鼠的乳腺中的积累减少。所有三组的血浆三酰甘油浓度均升高,并且脂蛋白脂肪酶活性在未生育和摘除幼崽动物的白色脂肪组织以及哺乳期动物的乳腺中降低。这些效应中的一些(但不是全部)在相同生理状态下模拟肿瘤负荷[埃文斯和威廉姆森(1988年)《生物化学杂志》252卷,65 - 72页]。
