2016年12月27日,Cell杂志发布了一条撤稿通知(下图),宣布2013年发表在该杂志上题为“Betatrophin: A Hormone that Controls Pancreatic β Cell Proliferation”的论文正式撤稿。在这篇文章,来自哈佛大学的科学家小组在肝脏中发现的一种名为betatrophin的激素能够在小鼠中控制胰岛β细胞增殖。



这篇论文发表时引起了强烈的关注,因为它提出了利用机体自身机制调控胰岛素产生的方法,为糖尿病患者摆脱注射治疗带来了希望。

参与这项研究的3位作者在撤稿通知中指出,2014年10月,发表在Cell杂志上发表的题为“ANGPTL8/Betatrophin Does Not Control Pancreatic Beta Cell Expansion”的文章指出,小鼠肝脏中betatrophin过表达增加了血浆中的甘油三酯水平,但并没有诱导β细胞的生长。Regeneron制药的Viktoria Gusarova是该研究的通讯作者兼第一作者。

当哈佛大学的研究小组在更多数量的小鼠中重复他们的实验时,也没有观察到基于betatrophin过表达的β细胞增殖。在Gusarova等人发表上述相反结果的同时,哈佛大学的研究小组也于同日在Cell杂志发表了题为“Perspectives on the Activities of ANGPTL8/Betatrophin”的Correspondence文章。

之后,研究小组与贝勒医学院Jake A. Kushner 的实验室合作,重复了多次实验,最终证明,betatrophin导致β细胞复制的结论是错误的。相关结果于今年7月发表在PLoS One杂志上(题目:Resolving Discrepant Findings on ANGPTL8 in β-Cell Proliferation: A Collaborative Approach to Resolving the Betatrophin Controversy)。

哈佛大学的研究人员在撤稿通知表示,他们对这一错误深表遗憾和歉意。原研究的通讯作者Douglas A. Melton说:“就像任何撤稿一样,这是令人失望的。但是对betatrophin假说的否定过程说明了当科学家意见不一致时是如何共同努力,推动领域的发展。”

Melton是干细胞研究领域的先驱者之一。上世纪90年代初,他的儿子被诊断为1型糖尿病。他一直致力于将干细胞转化为β细胞,希望能够用于治愈糖尿病。我们祝愿在2017年,科学家们能够取得新的研究进展,帮助数亿糖尿病患者。

Diabetes Care :新型糖源性蛋白质标志物和C反应蛋白在糖尿病、胰岛素抵抗和胰岛素分泌的研究

N-乙酰葡糖胺/半乳糖胺(GlycA)和唾液酸(GlycB)的糖化血清蛋白部分是非特异性炎症的评估指标,但是它们与胰岛素抵抗或胰岛素分泌的关系的相关资料知之甚少。近期,一项发表在Diabetes Care杂志上的研究评估了GlycA、GlycB和C反应蛋白(CRP)与胰岛素敏感性(胰岛素敏感性指数[SI])和胰岛素分泌(急性胰岛素反应[AIR])的直接测量关系。这项研究使用横断面分析方法,在胰岛素

2017年ADA《糖尿病医学诊疗标准》更新要点逐一看!

Diabetes Care杂志在2017年1月增刊中发布了美国糖尿病学会(ADA)的《糖尿病医学诊疗标准——2017》(以下简称ADA指南)。基于最新证据,ADA指南对多项诊断和治疗推荐进行了更新。ADA《糖尿病医学诊疗标准》旨在为临床医生、患者、研究人员、支付者等提供糖尿病护理、一般治疗目标的推荐,及护理质量评估工具。ADA每年都会对指南进行更新和修改,2017版指南的具体更新内容如下:促进

JAMA:糖尿病成美国“最昂贵”疾病,医疗支出超过心脏病

导语:发表在新一期《美国医学会杂志》上的研究分析了1996年至2013年间美国人在155种疾病上的个人医疗保健支出情况。结果显示,美国人在这18年间看病总共花费约30.1万亿美元,其中2013年支出约2.4万亿美元。美国一项新研究说,糖尿病是美国“最昂贵”的疾病,美国民众在这种慢性病上的个人医疗支出超过心脏病和腰背痛等疾病。这项研究发表在新一期《美国医学会杂志》上,它分析了1996年至2013年间

糖尿病成了美国很大的“无底洞”

最新研究显示,美国约一半的医药支出都用于治疗少数疾病,而打头阵的就是糖尿病,远远超过了其他疾病的支出总额。卫生计量与评估研究所(IHME)研究人员对155种疾病18年来的相关支出进行了研究。研究发现在这155种疾病中,有20种疾病的支出超出了总支出的一半。从全国医药总支出来看,糖尿病是最昂贵的一种疾病,2013年诊断和治疗的支出就达1010亿美元。缺血性心脏病的医药费总额为880亿美元,是2013

Diabetes Care:血清载脂蛋白与2型糖尿病的前瞻性队列研究

近期,一项发表在Diabetes Care杂志上的研究系统性评估了各种载脂蛋白的血清水平在2型糖尿病(T2D)疾病风险中的作用。研究共收集了971名受试者的各种检测数据。研究者们研究了HDL胆固醇(HDL-C)、apoA1、apoCIII、apoD、apoE以及apoA1载脂蛋白的比例与T2D风险的相关性。通过自然对数转化使所有载脂蛋白、比率值和HDL-C的水平达到正态分布。首先,通过使用线性回归

糖尿病患者的新福音,一张贴膜就能稳定血糖

可弯曲的无创电子贴膜配备了通过汗液来检测血糖的电化学感知器以及一枚电池用来在必要时加热微米针头以注入药物抽血和打针对于糖尿病患者来说可算是家常便饭,为了让他们免于这些“扎针”之苦,研究者们发明了一种可以直接贴在皮肤上面的电子贴膜。这张贴膜可以通过汗液来监控血糖并且在血糖超标时通过加热微米针头方式在皮下注入所需的降血糖药物。这张电子贴膜的原型机,是由来自首尔国立大学的助理教授金大亨(Dae-Hyeo
