導讀
Progerin,... and its expression has been suggested as a cause 
for dysfunctional nuclear membrane and premature senescence.
Progerin,......及其表達被認為是導致核膜功能失調和早衰的原因
In HGPS, aberrant splicing and processing of lamin A 
produces a protein called progerin, which induces early 
cellular senescence that is associated with increased DNA-damage signalling.
在HGPS(早衰症)中,核纖層蛋白A的異常剪接和加工產生稱為progerin的蛋白質,
其誘導早期細胞衰老,其與增加的DNA損傷信號傳導相關
Hutchinson–Gilford progeria syndrome (HGPS)
Hutchinson-Gilford早衰綜合徵(HGPS)
MMP-3 messenger RNA and protein levels decreased significantly 
with increasing donor age in HGPS fibroblasts but not in controls.
MMP-3信使RNA和蛋白水平顯著降低,但對照組則沒有
MMP-2 messenger RNA also showed a donor age–dependent 
decrease in HGPS fibroblasts, but levels of secreted protein were unchanged.
MMP-2信使RNA也顯示HGPS成纖維細胞的供體年齡依賴性降低,但分泌蛋白的水平未改變。
不過
In this in vitro system,A-beta was rapidly degraded through 
copper-mediated upregulation of  matrix metalloproteinase-2(MMP-2) 
and mareix proteinase-3(MMP3),
suggesting a potenial role for copper in reducing Aβ deposition 
in the brain of AD patients.
在這個體外系統中,A-β通過介導的基質金屬蛋白酶-2(MMP-2)和mareix蛋白酶-3
(MMP3)的上調而迅速降解,這表明銅在減少AD患者腦中Aβ沉積方面的潛在作用。
Manganese-superoxide dismutase (Sod2)
錳超氧化物歧化酶(Sod2)
The levels of MMP-2, -3, and -7 were also increased in the 
Sod2-overexpressing cell lines
在Sod2過表達細胞系中MMP-2,-3和-7的水平也增加
所以都和MMP-3有關,那到底是還是

第一種情況
Given that HGPS-patient fibroblasts display elevated ROS
HGPS-患者成纖維細胞顯示出升高的ROS
MnSOD activity protects mitochondrial morphology of quiescent 
fibroblasts from age associated abnormalities.
Mn(錳)SOD活性保護靜息成纖維細胞的線粒體形態免於年齡相關的異常
reactive oxygen species (ROS)
活性氧(ROS)
Overexpression of MnSOD decreased ROS levels
過量表達Mn(錳)SOD會降低ROS水平
活性氧類(英語:Reactive oxygen species,ROS)
過高的活性氧水平會對細胞和基因結構造成損壞
Lamin A是支持核膜的結構蛋白質,因此早衰症病人的細胞核核膜有一半出現畸形。
節錄自https://zh.wikipedia.org/zh-tw/早年衰老症候群
progerin(PG)
mesenchymal stem cells (MSCs)基質間充質乾細胞(MSCs)
lamin A (LMNA) 核纖層蛋白A(LMNA)
Furthermore, both PG and LMNA-MSCs showed a decrease in manganese superoxide 
dismutase (MnSODM)
PG和LMNA-MSCs均顯示錳超氧化物歧化酶(MnSODM)減少
several studies have reported declines in MnSOD activity 
during diseases including cancer, aging, progeria, asthma, 
and transplant rejection.
一些研究報導,在癌症,衰老,早衰,哮喘和移植排斥等疾病期間,MnSOD活性下降
所以應該是

第二種情況
Notably, in our investigations the ATP content of progeria fibroblasts 
was only approximately 50% of that found in healthy controls. 
值得注意的是,在我們的研究中,早衰成纖維細胞的ATP含量僅為健康對照組的約50%
紅細胞內ATP含量與紅細胞內含量正相關(成正比)
,血清、肝臟ATP酶活性降低。
在給後,ATP 酶活性增加 65%。
上方已經知道成纖維細胞含有
Mn(錳)SOD活性
可是
在哺乳動物細胞中,約90%的ATP由線粒體通過氧化磷酸化產生
Pharmacological suppression of systemic copper impairs 
oxidative phosphorylation and tumor growth
全身銅的藥理學抑制損害氧化磷酸化和腫瘤生長
(所以和氧化磷酸化有關)
For the study we used fibroblasts, which express SOD1 
at physiological levels under regulation of the native promoter.
對於該研究,我們使用成纖維細胞,其在天然啟動子的調節下在生理水平表達SOD1
(所以成纖維細胞含有SOD1https://zh.wikipedia.org/wiki/超氧化物歧化酶含有。)
MnSOD is vital for scavenging superoxide radicals generated 
during oxidative phosphorylation and may inhibit ROS-induced 
inactivation of these complexes.
MnSOD對於清除氧化磷酸化過程中產生的超氧化物自由基是至關重要的,並且可以抑制ROS誘導的這些複合物的失活
所以到這裡
也許和ATP減少有關
早衰如同上了年紀的人:頭髮稀少,皮膚很薄且無毛
既可以防止掉髮又可以刺激毛囊生長
所以有沒有可能

第三種情況
Accumulation of a truncated farnesylated prelamin A form, 
called progerin, is a hallmark of the severe premature ageing syndrome
, Hutchinson-Gilford progeria. 
積累的截短的法尼基化prelamin A形式,稱為progerin,是嚴重的早衰綜合症的標誌
,Hutchinson-Gilford早衰。
Rapamycin treatment of progeria cells lowers progerin, 
as well as wild-type prelamin A levels
雷帕黴素治療早衰細胞降低了progerin以及野生型prelamin A水平
Importantly, rapamycin treatment does not affect lamin C protein levels, 
but increases the relative expression of the prelamin A endoprotease ZMPSTE24.
重要的是,雷帕黴素處理不影響核纖層蛋白C蛋白水平,
增加了prelamin A內切蛋白酶ZMPSTE24的相對表達
據查內切蛋白酶ZMPSTE24(含鋅酶)和降解progerin有關
所以也有可能

總結以上
早衰症都有可能
建議可以喝亞培安素草莓口味補充
其它含鋅銅錳高的食物http://blog.eyny.com/blog-5788411-733718.html

人類的壽命取決於基因端粒,長端粒代表年輕細胞,短端粒代表細胞衰老,如果端粒太短,就會停止分裂,短端粒是人類細胞老化的主要原因之一。
發現端粒實際上可以變長,簡言之就是老化是一動態過程,可能會加速或減緩,甚至可以逆轉。

端粒(英語:Telomere)是染色體末端的DNA重複序列,作用是保持染色體的完整性和控制細胞分裂週期。

某些細胞,如幹細胞和生殖細胞,能夠進行分裂,因為它們含有活性端粒酶,一種延長端粒的酶。
端粒酶活性催化單位(hTERT)
DNA 甲基化水平也可以作為細胞分裂的”計時器”。
隨著細胞分裂次數的增加,端粒不斷縮短。
hTERT 啟動子若是有甲基化的情況下染色體端粒酶活性會被抑制
抗甲基化的營養有很多:鎂、硒、維它命C、兒茶素、花青素、大豆異黃酮、蜂膠黃酮...
