Gene Loss in Humans

Aging is process of getting older and losing our optimum work efficiency. As a result of aging, many changes occur in humans which many would have seen and experienced.

The primary reason for this aging is the fact that many cells lose their functionality and do not work at their peak. The major reason due to this is gene loss or gene repression. It is estimated that human body contains more than 30,000 genes. Of these numbers, some 5000 genes are responsible for physiological activity. If these genes get damaged are do not work properly, then aging starts. The genes are also called as messengers. These send chemical signals to all the cells on their function and the cells follow the code. When the transportation is interrupted, the cells cannot work properly. Hence aging will occur.

These types of genes are also responsible for passing the immunity information. On loss of these genes, the immunity also falls down, which is also a symptom for aging. Gene loss can be mainly due to the fact that the genes get damaged. The damage may be due to physical means or due to a disease attack. Some diseases attack these genes and hence they get lost. Gene loss might also lead to gene repression. Gene repression means the inability to provide information to the cells on their function. This also results in aging. The gene loss cannot be controlled but can be reduced. The only possibility is by giving them constant work. Many researchers have found that gene loss is the cause for several diseases like Alzheimer’s disease, Parkinson’s disease etc.  Hence one has to control this gene loss in order to postpone aging.
