【衰老新突破:新分子可以使衰老的细胞重获新生】埃克塞特大学分子遗传学小组发现了一种恢复不活跃衰老细胞的新方法。可以在几个小时之内,使衰老的细胞重新正常分裂。此次研究重点在于研究小分子调制剪接因子表达,从而救援细胞衰老问题,研究结果发表在《BMC细胞生物学》杂志中。

【衰老新突破:新分子可以使衰老的细胞重获新生】埃克塞特大学分子遗传学小组发现了一种恢复不活跃衰老细胞的新方法。可以在几个小时之内,使衰老的细胞重新正常分裂。此次研究重点在于研究小分子调制剪接因子表达,从而救援细胞衰老问题,研究结果发表在《BMC细胞生物学》杂志中。

埃克塞特大学的研究团队发现剪接因子可以重新激活化学物质,使衰老细胞不仅看起来年轻,而且还可以像年轻细胞似的开始分裂。在此次研究中,研究人员应用一种物质叫白藜芦醇的类似物,这种物质一般存在于红酒,黑巧克力,红葡萄和蓝莓中。拼接因素引起化学物质进行切换,把随着年龄逐渐关闭的细胞唤醒,数小时内,细胞看起来年轻了,并且开始进行正常的细胞分裂。

这一发现很可能带来更好的疗法,来帮助人们应对退行性衰老的影响。大多数人都会经历某种慢性疾病,这是随着年龄的增长引起的问题,比如说,老年人更容易中风,患心脏病和癌症。

研究人员表示:“此次研究的目的不仅希望延长人类的寿命,还希望人类可以健康的度过一生。我们的数据表明,使用化学物质来切换的主要类基因,可以让老旧的细胞恢复功能。当我看到培养皿中的细胞重获新生时,我也不敢相信自己的眼睛,因为速度真的是太快了,就像变魔术一样,这些衰老的细胞真的恢复了,因此,我又进行了反复的验证,多次重复实验的过程中,在每种情况下细胞都可以新生。”

Nat Med:衰老细胞引发骨质疏松?有望治疗老年性骨质疏松

近期,来自于梅奥诊所的科学家们以小鼠为模型发现,衰老细胞与老年性骨质疏松之间存在因果关系。他们发现,借助于抗衰老药物靶向清除这些衰老细胞,有望治疗老年性骨质疏松,改善骨骼质量和健康。

衰老细胞可引起骨性关节炎

研究的合著者,来自明尼苏达州罗切斯特梅奥诊所Robert和Arlene Kogod老年中心主任James Kirkland博士及其同事在《老年医学杂志,A辑:生物科学与医学科学》上发表了他们的研究结果。骨性关节炎(OA),又称为退行性关节疾病,是软骨组织——关节内保护骨骼末端的组织——不断磨损,导致其下方的骨骼产生摩擦所致的一种疾病。这种疾病可能会导致疼痛、肿胀、和关节运动障碍。当病情恶化时,骨骼

Science:暗中使坏的衰老细胞

动脉粥样硬化(Atherosclerosis)的斑块会使动脉血管变窄,进而导致心脏病和中风。Mayo诊所的研究人员通过动物模型发现,衰老细胞推动了动脉粥样硬化的斑块形成。健康细胞遭遇压力的时候会发生衰老。它们在这一过程中释放的生物活性分子,被称为衰老相关分泌表型(SASP)。这些分子可以分解正常组织结构,还能吸引免疫细胞造成局部炎症。Mayo诊所的研究人员通过动物模型发现,衰老细胞推动了动脉粥样硬

Nat Med:清除衰老细胞使关节重焕青春

骨关节炎(osteoarthritis)是一种困扰着许多中老年人的疾病,它是由于关节中软骨由于运动或其它原因造成损伤后出现退化,导致关节内出现骨质增生而形成慢性炎症。该病的主要症状是关节疼痛和肿胀,严重影响日常生活。▲健康的关节中(左),软骨覆盖骨头的末端,充当垫子或减震器,并且在骨骼之间提供光滑的表面。在骨关节炎中(右),软骨发生损伤,骨头会相互摩擦,随着时间的推移,这种摩擦会永久损坏关节。(图

J Gerontol A Biol Sci Med Sci:研究首次证实骨关节炎与衰老细胞之间存在因果关系

近日,发表于The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences的一项新的研究发现表明,细胞衰老是引起骨关节炎的一个原因,因而他们认为靶向治疗这些衰老细胞或可为骨关节炎的预防及治疗提供一种新的方法。 虽然既往研究显示,骨关节炎的发生或与细胞衰老有关,但是确切的机制尚未可知。细胞衰老是指细

Science:衰老细胞伤害心脏?

衰老细胞不仅仅造成机体衰老,它们还会导致动脉粥样硬化,对心脏造成严重损失。这是美国梅奥诊所的研究团队发表在《Science》期刊的最新研究结果。科学家们以小鼠为模型,发现体内的衰老细胞会参与动脉内脂质沉积,为心脏病或中风等心血管疾病埋下风险。细胞是生命体结构和功能的基本单位,也是机体衰老的基本单位。个体细胞因经历损伤或者自然退化等原因而衰老后,会被免疫系统正常清理,同时相应组织器官会生成新的细胞弥
