Ageing-Disease Conundrum

In line of recent blog post of whether ageing is a disease or not? A news report published in "New Scientist" brings out an important angle or reason is to why there is a need of including ageing as disease in upcoming International List of Causes of Death  (ICD)-11 classification. Homeostasis is one of the most favourite phenomena of nature.  Hence, every idea has its own merits and demerits. 

Upon asking an important question on a scientific forum wether ageing is a disease or not. I was given following reply by a distinguished Professor:

  1. yes ("disorder of structure or function in an animal or plant of such a degree as to produce or threaten to produce detectable illness or disorder").
  2. no ("the quality which identifies disease is some deviation from a biological norm").

Is ageing a disease? - ResearchGate. Available from: https://www.researchgate.net/post/Is_ageing_a_disease [accessed Nov 28, 2015].

I can see some clear confusion here. When we see definition "2" as mentioned above; ageing leads to Cardio vascular abnormalities, Central Nervous System (CNS) abnormalities, anatomical abnormalities, fatigue, prostate problems in males and many other problems. Hence, the question Is it not deviation from biological norm?

Moreover, one of the most important question "How much can human life span be extended"? is one of the top 25 questions to be answered, published by Science magazine.

Not including ageing as a disease has created many restriction towards availability of collaborative efforts, funding and other resources for carrying out cutting edge research to solve the problems pertaining to ageing. The question of including ageing as disease has been more of an ethical instead of scientific conundrums as pointed by Dr. Alex Zhavoronkov in his recent press release here.

Is ageing really a disease?

From my previous discussions on

A) Personalised cancer therapy

B) Cancer and ageing relation

C) Important breakthroughs in cancer and ageing

D) Long living rats

E) Scientific perception of Indian scripture for longevity: Dr. Sinclair and Dr. Zhavoronkov's idea.

It is surprising that ageing is not been classified as a disease.

It is indeed debatable that whether ageing is a disease or a generalised and universally accepted phenomenon? Being a pharmacist or medical practitioners we normally follow guidelines of standards set by World health organisation (WHO), Centre for disease control (CDC), United states pharmacopeia (USP), British pharmacopeia (BP), Indian pharmacopeia (IP) and others.  

Recently, a paper published by Dr. Alex Zhavoronkov raises a cascade of questions as discussed below.

If "Ageing" is never been considered as a disease up till now then why are we trying to cure it? or slowing down the process? or trying to find out a molecule which can provide longevity? Why the health supplement industry is growing enormously compared to any other pharmaceutical industry?

It is evident that cross over from ageing to pathological conditions like age related diseases often takes place as shown in figure. As a result we have deadly diseases like cancer, cardiovascular diseases, central nervous system diseases and others. The paper clearly explains how the united efforts to fight against ageing is most important from both scientific and economic perspective. Importantly, the paper discusses about the reasons why it is essential to classify ageing as disease in up coming 11th international statistical classification of diseases and related health problems (ICD-11), expected to be finalised in 2018.

Significance of this paper and insight of Dr. Zhavoronkov, CEO Insilco Inc. is discussed by www.eurekaalert.org. Please click here for more details.

Anti-ageing: A reality or myth?

From Mahabharata to Science

The idea of Not Ageing is indeed like looking into an indian mythology of Mahabharata. 
Where people are mentioned to have unusually long lives. It is one of the oldest known Indian scripture researched by many archeologists, medicine experts and physicist. Many known scientists have known to acknowledge this intriguing scripture for their well known scientific works that includes Albert Einstein or J. Robert Oppenheimer.

It is said that people had long lives in ancient era of Mahabharata that is around 1000 years. May be this is a truth or myth. Sage Vyasa who is known to have written this ancient scripture lived across approximately 6 generation of kings and have narrated their stories in Mahabharata. Some people with their logical reasoning think that he may have lived around 130 years without any health issues. Whereas, some assume that he may have lived way longer than that.

Important point is that we have reference of longevity in ancient literature, question is do we believe in having scientific basis for long and healthy life?

Voice of Insilco Inc, CEO: Dr. Alex Zhavoronkov

It shows a far fetched vision of company which truly believes that longevity is possible. But is it a dream/ struggle or some kind of myth? Evidence of naked mole rat discussed previously in our blogs suggests that this may be possible. As it is the only rodent, which points in the direction of not only having resistance towards cancer but also towards other age related diseases. 

A group of scientists believe that at cellular levels,  mTOR and Telomerase may play a crucial role in cancer therapy and attaining longevity as discussed previously. On the other hand Prof. David Sinclair in his video published in TEDx series explains his life's journey to find reason behind ageing.



He talks about one more miraculous protein which may be involved in ageing process called as  Sirtuin.                                        .............................................. yeast ageing mechanism click here.
                                    ............................................... role of sirtuin in age related diseases click here.

Perhaps, this insight may help in unrevealing deeper mysteries of long life and a way to treat cancer by using Personalised medicine method.

Cancer Resistant And long Living Rodent

In our previous blogs we discussed about Peto's paradox. We also discussed about personalised medicine for cancer therapy and funding possibilities for fighting against cancer.

In most published literature mice  are often used as model to extrapolate molecular research for cancer and ageing to human conditions. This extrapolation often fails due to variation in molecular and metabolic levels.  For more details please check here.

Further, we also discussed recent strategies of using targets like mTOR and Telomerase for treating cancer and age related diseases.

Important question is mice (a rodent species) be used for getting useful information about problems of fighting cancer or longevity?

video of showing of naked mole rats can help preventing cancer

It is said that "Answer to major natural  problems will come nature". Somewhere in 2013 it was discovered that a species of mice, which shows resistance to cancer it is called as "Mole Rats"

Although, it is a ugly looking nude mice but it is an interesting animal showing resistance to cancer. 

For more details about the animal please read here.

A simple molecule called hyaluronic acid (HA) produced by this animal is responsible for preventing development of cancer. However, scientists believed that there may be more to this idea. They think that other mechanisms along HA induced effects may play role in preventing developing cancer in mole rats. 

Unusually, molecular weight of HA from mole rat is five times higher than humans which provides protection to mole rats against cancer.   Scientific paper can be accessed here.

Please click here to check genome sequence web-portal for more in-depth research.

This rat seems to be resistant to age related diseases including cancer. Further, it has striking life of 30 years, that is longer than the normal mouse with life span of maximum 4 years. This makes mole rats an unusually long living rodents. More details can be seen here.

Hence, unfolding of the biomechanics of this organism may help us to find newer ways of cancer therapy and attaining longer life.

Some sources says  "If a human was to have same lifespan as a naked mole rat, relative to its size, they would live for up to 600 years"............................click here.


Recently, in 2015 identified new protein product pALTINK4a/b  which may be responsible for inducing longevity in these rats. They were able to correlate dependency of expression of pALTINK4a/b  in presence of high molecular weight HA in mole rat............................................ This may finding can be accessed here.

May be his new finding may help to find newer ways of longer life.
