Cell:节食有益健康可能与内源性硫化氢(H2S)有关

2014-12-31 佚名 生物谷

Harvard School of Public Health (HSPH)一项新的研究识别饮食限制或减少食物摄入量(但并没有营养不良)健康益处背后的关键分子机制。限制饮食也被称为限制热量摄入,最出名的是它能够减慢实验动物衰老。 结果表明,限制两个氨基酸,蛋氨酸和半胱氨酸,会导致硫化氢(H2S)的生成升高,保护防止缺血再灌注损伤。饮食限制增加H2S生成也与延长蠕虫、果蝇和酵母寿命有关。虽然H

Harvard School of Public Health (HSPH)一项新的研究识别饮食限制或减少食物摄入量(但并没有营养不良)健康益处背后的关键分子机制。限制饮食也被称为限制热量摄入,最出名的是它能够减慢实验动物衰老。

结果表明,限制两个氨基酸,蛋氨酸和半胱氨酸,会导致硫化氢(H2S)的生成升高,保护防止缺血再灌注损伤。饮食限制增加H2S生成也与延长蠕虫、果蝇和酵母寿命有关。虽然H2S气体大量时会剧毒,但低水平也存在于天然硫磺泉水中,并早已与健康好处有关。哺乳动物细胞也产生低水平硫化氢,但是这是第一次有研究证实这种分子直接与饮食限制对健康益处有关联。

这一发现表明,H2S是哺乳动物和低等生物饮食限制所带来好处的关键分子之一。虽然更多的实验都需要了解H2S如何发挥其有益的作用,但是在研究这些分子在打击人类疾病和衰老中它给了我们一个全新的视角。这项研究发表在Cell杂志上。

饮食限制是一种类型的干预,可以包括整体食物摄取减少,降低特定营养素如蛋白质的消耗或间歇禁食。已知的是饮食限制具有有益的健康作用,包括防止组织损伤和改善代谢。饮食限制已经显示出延长多种模型生物体的寿命,从酵母到灵长类动物。但解释这些效果的分子机制尚不完全清楚。

第一作者Christopher Hine和他的同事证实,饮食限制一周,能增加小鼠抗氧化反应和保护肝脏缺血再灌注损伤,但出人意料的是,这种保护作用即使在动物没有这样抗氧化反应的小鼠中也可能是完整的。相反,研究人员发现H2S生成增加的这种保护效应是基于两个含硫氨基酸,蛋氨酸和半胱氨酸摄入量减少。当饮食中补充这两种氨基酸后,H2S生成增加和饮食限制益处均被抑制。

研究人员还发现参与H2S生成的基因对于其他生物包括酵母,蠕虫,果蝇饮食限制长寿好处也是需要的。这些发现使我们更好地理解如何干预饮食延长寿命和防止损伤

JCO:耶鲁专家建议药企在乳腺癌药物试验中设置饮食或锻炼对照组

美国耶鲁大学公共卫生学院副教授Melinda Irwin博士发文建议,制药企业应在癌症药物试验中设置生活方式干预(例如锻炼和饮食干预)组,作为活性对照组。(JClinOncol.2014年6月16日在线版)Irwin博士强调,这在药物获益较小或者某种药物的摄入或依从性较低时尤其有价值。她表示,目前针对此类干预的研究缺乏政府资助,所以药企应考虑实施这个大胆的试验设计建议。Irwin 博士指出,由于

Lancet Diab & Endo:控制饮食快速减肥并不会加速反弹
