科学家发现可刺激β细胞生长的激素近日有研究者报道,他们新发现了一种能刺激胰岛β细胞生长的激素,并将其命名为“β调理素”(betatrophin)。这种激素由肝脏和脂肪细胞产生,在体内可起到刺激胰岛β细胞生长的作用。在动物试验中,该激素可使小鼠体内β细胞的生长速度提高12倍。研究者表示,假如人体试验证实这种激素能大大增加体内β细胞的数量,那么它对于糖尿病患者而言将会是一个天大的好事。不过这一研究尚处于初级阶段,研究者甚至还不知道“β调理素”是如何起作用的,因此在其能作为药物应用于
Scientists Discover Hormones That May Promote β Cell Growth Recently, researchers report that they have newly discovered a hormone that stimulates the growth of pancreatic β cells and named it “betatrophin.” This hormone is produced by the liver and fat cells and acts to stimulate the growth of islet beta cells in the body. In animal tests, the hormone increases the rate of β-cell growth in mice by a factor of 12. The researchers said that if the human test confirmed that the hormones can greatly increase the number of β cells in vivo, then it will be a great good for diabetes patients. However, this study is still in its infancy, and researchers do not even know how “beta regulators” work, so they can be used as drugs in
