Holding age still an obsession many experts cells. Now the demand is increasing; still young, and age-fold. Can it done?
Extend the target is to be applied to humans. But it would be difficult to be done remembering the human research is so slow growing old human. Maybe the first researcher died before the research is complete.
Therefore, the experts returned to the objects of an age short enough. Among the fruit fly (Drosophila), or worm, a count of age in weeks or months. After trying a variety of ways, today found a way to increase the age of the animals up to two times. Remarkably, the additional age was not on the condition of their age (the term, youth) but it happened since they were young. So the young animals that are extended. Among researchers then launched an obsession to make people able to "die young" in old age.
Michal Jazwinski from Louisiana State University School of Medicine in New Orleans have discovered a gene called LAG-1 as a cause of aging in fruit flies. When the gene was taken or replaced with another gene, with the age of the animal itself will increase 100 percent.
Age increase was calculated ideal Seara. This means that the relevant animals are not exposed to disease or accident which forced him to change way of life. Addition of age correlated with the slow aging process is going through. Then if there are no side effects of genes taken it? Surely there must be, but until now still in the research phase.
Others again with what happened at the micro worms (nematodes) which is the object of research. These animals also have the potential to be longer because of his age have certain genes that age longer than the others. When these genes is maintained during the adult population of the earthworm, nematode itself would be able to increase the age to one hundred percent. It can keep away from various types of interference that could be dangerous.
But there is also a natural way from this animal species to extend the age. That is by protecting themselves from all kinds of attacks, whether it be an impact, heat, and the types of specific chemicals. There is a gene called AGE-1 that produce enzymes the immune enhancer. In moments of need, these genes will encourage the production of more enzyme. This way proved to increase the age of the worms by 70%.
Does the discovery of the animals bida directly comparable with that in humans? Still too complex. The problem is that the object of most of the animals are single-celled, while in the human body, the relationship between cells is so complex.
But that does not mean impossible. When the effect of LAG-1 decision can be overcome, and the stimulation of AGE-1 is successful, human being will experience the same thing. In fact, there might be other genes in humans that can be researched and potentially increasing age.
The researchers also did not expect that people would prefer to age too long. Therefore they do not want to promise double the age, for example, or hundreds of years. According to them, people are going to earn much more than 125 years, despite a healthy body condition. "What we imagine, someone finish the job at the age of 65 years, and then fill in retirement for 30 years with the body remains healthy," he said. Brown, director of the lifespan biosciences. Their first target is megatasi heart attacks and aging skin. But the most important thing that should not be forgotten by them. Age man in God's hands, so even though we have very sophisticated technology too, but if God has set our death, human beings will not be able to postpone death for picking.
