PNAS:转座子影响衰老又出新成果,节食或可延长寿命

2016-09-15 佚名 生物探索

转座子是基因组中一段可移动的DNA序列,它可以通过切割、重新整合等一系列过程从基因组的一个位置“跳跃”到另一个位置,在异染色质中含量丰富。近日,来自布朗大学的研究提出衰老过程的转座子理论。科学家认为,转座子是一个“无赖”的DNA元件,以至于它可以打破衰老细胞防守,在基因组其他地方插入自身DNA,造成细胞功能紊乱,影响寿命。这项研究发表在近日的PNAS杂志上。此前研究表明,随着细胞衰老,致密的异染色

转座子是基因组中一段可移动的DNA序列,它可以通过切割、重新整合等一系列过程从基因组的一个位置“跳跃”到另一个位置,在异染色质中含量丰富。近日,来自布朗大学的研究提出衰老过程的转座子理论。科学家认为,转座子是一个“无赖”的DNA元件,以至于它可以打破衰老细胞防守,在基因组其他地方插入自身DNA,造成细胞功能紊乱,影响寿命。这项研究发表在近日的PNAS杂志上。


此前研究表明,随着细胞衰老,致密的异染色质结构变得越来越松散,失去了对转座子的束缚能力。转座子因此脱离它们在染色体上的位置,移动到其他染色体上,从而干扰正常细胞功能。同时,科学家也证明一些干预措施,比如限制热量或者调控某种基因,可以明显延长实验动物的寿命。在这项研究中,实验人员进行了几个实验考察了转座子表达增强异染色质位点和衰老以及寿命的关联。

转座子在衰老细胞中表达增加,可以通过限制饮食缓解

在本研究中,科学家利用二代测序技术,发现衰老果蝇的头部和脂肪体内异染色体上的转位元件等基因转录水平上升。

转座子活性并非稳定地随着果蝇年龄的增长而上升。当果蝇达到一定的年龄,转座子的活性出现指数增长。实验数据表明,当果蝇接近死亡时,转座子活性才真正开始增强。

本研究给出了一种重要的干预措施来延长寿命,这种措施也是一种众所周知的养生途径——饮食限制。这个方法缓解了衰老诱导的异染色体上转座子等基因的表达量增加。

衰老引起的转座子表达增加可以通过干扰影响异染色质结构的基因来减弱

为了进一步探索转座子表达和寿命之间的关系,研究小组测试了一些影响异染色质结构的基因调控的影响,这些基因不仅存在于果蝇中,也存在于哺乳动物中。比如,增强Su(var)3-9基因的表达,有助于形成异染色质,可将果蝇的寿命由60天延长到80天。增强Dicer-2基因的表达,可以通过小RNA途径抑制转座子,同样明显延长寿命。

最后,研究人员发现了一种名为3TC的抗HIV的药物,它可以抑制转座子激活及移动到基因组的新位点之中,该药物在一定程度上延长Dicer-2基因突变的果蝇的寿命。

不过,根据这些结果科学家还不能确定转座子是引起衰老健康问题的主要原因。接下来,研究小组准备过表达转座子看它是否会损害健康,缩短寿命。或者用CRISPR基因编辑技术禁止转座子在基因组之间移动。如果这种干预措施可以影响寿命,那将能更好地说明问题。不过,尽管在本研究中转座子看上去在衰老过程中扮演着重要角色,研究人员仍然认为,有许多潜在机制都影响着衰老过程,转座子只是其中之一。

神药二甲双胍将开始延缓衰老临床试验

最近美国医生Nir Barzilai准备开始一个延缓衰老的临床试验,使用的药物是古老的糖尿病药物二甲双胍。试验计划招募3000老年人,一组使用二甲双胍,一组使用对照。然后观察衰老过程。由于衰老本身并不是疾病,所以这里的二甲双胍严格地讲不能算药物。因为FDA只监管食品、药品、保健化妆品所以严格地讲这也不在FDA监管范围。但Barzilai已经和FDA沟通并获得FDA允许。这将是第一例延缓衰老的临

走路速度能预测寿命!?(内附走路速度自查方法)

美国匹兹堡大学的研究者曾综合9项研究做出总结:走路速度的快慢可以很好地预测寿命长短:普通人的走路速度是每秒钟0.9米;走路速度低于每秒钟0.6米的人死亡的可能性会增加;走路速度超过每秒钟1米的人寿命较长。为啥走得快就寿命长?步行时,人体的60%~70%的肌群参加活动,需要消耗大量的身体能量,需要包括呼吸系统、循环系统、神经系统以及肌肉骨骼系统在内的多个器官系统的支持和配合。而步行速度慢一方面反映老

Nature:科学家证实吃七分饱,会显著延长寿命!

来自于鹿特丹大学、国家公共卫生与环境研究所(RIVM)的研究团队近期在《Nature》期刊发表文章证实,如果患有严重衰老疾病的小鼠减少30%的食量,它们的寿命将会延迟3倍。更重要的是,相比于正常饮食的小鼠,控制饮食结构的小鼠会更健康。这一发现对于患有早衰疾病的儿童有着重要意义,它有望帮助揭示老龄化疾病的病因,例如阿尔兹海默症、帕金森症。减少30%的食量,延迟3倍寿命最初,通过修改基因,研究团队构建

Oncotarget:六种植物提取物具有强大抗衰老作用

最近在国际著名期刊Oncotarget杂志上发表一项新研究中,来自加拿大康考迪亚大学和Idunn Technologies Inc的研究人员,揭示了一个重要的因素:含有六组抗衰老分子的植物提取物。 在这项研究中,研究小组对Idunn Technologies Inc广泛的生物库进行了搜寻,进行了10000多项试验,来筛选能延长酵母时序寿命的植物提取物。 为什么选用酵母?从细胞学上来说,衰老

开灯睡觉或能加速衰老

有些人开着灯也能睡着。不过这可能不是一件好事。一项新的研究表明,过度暴露在人造光源中,有可能加速老化,并导致其他健康问题。全球有超过五分之四的人身处光污染中。此前已有研究暗示了人工照明可能带来的负面影响,既有显而易见的问题,如糟糕的睡眠质量;也有相当恐怖的风险,如增加的乳腺癌风险。不过,这些都还只是间接关联——研究尚未发现人造光源和健康问题间存在直接联系。为了弄清楚这一问题,荷兰莱顿大学的研究者补

全球输血治疗衰老临床试验进行中,硅谷大神彼得·蒂尔充满期待

如果一切进展顺利的话,全世界首个利用年轻人的血液「治疗」衰老的临床试验,已经在美国加利福尼亚州蒙特雷市的某个门诊开始了。这是人类以另一种方式再一次向「永生」出击,只不过这一次的临床研究会让人感到一丝丝「不安」。尤其是在Inc爆料美国著名企业家与风险资本家、PayPal联合创始人彼得·蒂尔(Peter Thiel)对此事表现出极大的兴趣,似乎很有兴趣尝试这种治疗,于是人们开始反思关于「永生」的一
