The semi-essential amino-acid taurine is involved in glucose homeostasis either in adults or in parental life. Taurine is currently used in neonatal life because it is added to milk formula for babies, and to parental solution for prematures. Here, it has been examined whether taurine administration in lactation modifies adult glucose metabolism. Neonatally taurine-treated mice (50 mg/kg body weight/day, for the first 21 days of life) as adults have lower basal glucose and iAUC after glucose loading curves in comparison with vehicle-treated mice, whereas iAUC following insulin loading curves, plasma lipids and malondialdehyde (MDA), an index of lipid peroxidation were not significantly changed. Thus, in rodents, neonatally administered taurine produces enduring effects in a way that could be advantageous for the control of glucose homoeostasis.
半必需氨基酸牛磺酸在成人期或出生后早期都参与葡萄糖稳态调节。目前牛磺酸用于新生儿期,因为它被添加到婴儿配方奶粉和早产儿的肠外营养液中。在此,研究了哺乳期给予牛磺酸是否会改变成年后的葡萄糖代谢。与给予赋形剂处理的小鼠相比,成年后经新生儿期牛磺酸处理的小鼠(出生后第1天至21天,50mg/kg体重/天)基础血糖较低,葡萄糖负荷曲线后的胰岛素曲线下面积(iAUC)也较低,而胰岛素负荷曲线后的iAUC、血浆脂质和脂质过氧化指标丙二醛(MDA)无显著变化。因此,在啮齿动物中,新生儿期给予牛磺酸会产生持久影响,这可能有利于控制葡萄糖稳态。
