“日本人も中国人も汉字を”体重减重后日本人も中国人も汉字を为何出现反弹?国际最新研究揭秘细胞保留肥胖“记忆”

  中新日本人も中国人も汉字を网北京11月19日电 日本人も中国人も汉字を(记者 孙自法)体重减重后出现反弹让减肥人士颇为烦恼,反弹原因很受关注。国际学术期刊《自然》最新发表一篇健康研究论文称,小鼠和人类细胞实验表明,在减重以后脂肪组织通过细胞转录和表观遗传变化,保留着肥胖的“记忆”,从而增加体重反弹的几率。

  论文作者认为,这项研究发现或有助于解释节食或其他减重策略后经常出现的反弹问题(也称“溜溜球效应”),即减重者减掉的体重又恢复了。同时,或有助于为未来的体重管理策略提供信息。

  该论文介绍,治疗肥胖和改善健康的一个主要目标是减轻体重,预防继发并发症如2型糖尿病或脂肪肝等。注重节食和生活方式改变的策略常常只能带来短期减重,减掉的体重可能会随着时间推移慢慢反弹——即所谓的“溜溜球效应”。这一问题似乎是由某种肥胖“记忆”引起,但造成这一作用的机制尚不清楚。

  在本项研究中,论文通讯作者、瑞士苏黎世联邦理工学院Ferdinand von Meyenn和同事及合作者共同研究发现,人类和小鼠的脂肪组织细胞在体重明显减轻后仍然保留了转录变化。通过比较18名非肥胖症患者和20名患有肥胖症、经减肥手术减重(BMI至少减少25%)的参与者减重前后脂肪组织细胞的RNA序列,他们找出了这些变化。

  研究人员对瘦小鼠、胖小鼠和曾经胖过的小鼠(肥胖然后减重的小鼠)也进行了类似分析。在小鼠中,他们还发现表观遗传变化和转录变化,这些变化似乎与减重后持续的一些代谢过程(如脂肪酸生物合成和脂肪细胞形成)受损有关,研究认为这可能导致了节食后体重反弹。

  论文作者总结说,未来以脂肪和其他潜在细胞的这些变化为靶标,或可改善长期体重管理和健康结局。(完)
