Epigenetics: interaction between genes and environment | Diseases and conditions.

ADS

Epigenetics is the way in which are expressed genes depending on environmental factors and habits of life, and explains why the twins may develop different diseases.
Epigenetics is the way in which our genes are expressed depending on environmental factors and habits of life; explains the impact of the environment and the lifestyle on the workings of genes and that, for example, in the case of twins, while they have the same genetic information, one can develop cancer and the other is not, because your body responds differently to external factors.
The characteristics of the environment and personal choices - diet, exercise, sleep, smoking, consumption of alcohol--affect the genetic code. In addition, changes that occur in the same can be transmitted to the offspring because they also affect eggs and sperm, leaving its mark on them.
Exposure to toxins and harmful substances trigger mutations in the genome that can be inherited by the children, grandchildren and great-grandchildren. Epigenetics implies an increase in genetic information, but it can be for good, and benefit the health of the individual by activating natural barriers that prevent against the development of certain diseases, or worse, causing dysfunction that favors pathological situations.

Epigenetics and disease development

Scientists have found that the development of diseases is due both to genetic alterations, such as epigenetic; in fact, if you analyze the DNA of one person with many years of difference, be observed more epigenetic differences than genetic.
Epigenetics does not alter the DNA sequence of genes, but if its expression varies, and the types of epigenetic alterations most important that have been discovered so far include DNA methylation, a mechanism linked to the onset of cancer.

As explains Manuel Esteller, director of the Epigenetics laboratory of the National Center of oncological research (CNIO)cancer epigenetic changes are altered, and there is an imbalance which means that certain tumor suppressor genes do not work well and do not inhibit the cancer because they are incorrectly methylated.
Although it is still difficult to determine the relationship between certain environmental agents, such as for example the type of feed, and epigenetics, if you manage to identify the epigenetic factors influencing the onset of certain diseases, it could act upon them, change them to avoid dysfunction of the affected genes, thus preventing some pathological, such as obesity or arthritis , or slowing the Aging process
