Illness, wisdom, talent: Don't pour out all the genes!

The family looks a new born baby. Suddenly someone said: 'The boy has the eyes of his mother', another said: 'Look at these legs - the boy will become a father-like player'. But according to scientists, many things are not fixed right after conception.

Babies may have beautiful eyes of their mothers, healthy legs of their father but their intellect, talent and disease are decided by their lifestyle.

Gene has a 'switch'

As children grow up, the expression of intelligence, musical ability or sport will be said to be related to smart, good family members in other fields. What about talents like any relatives or relatives? Where do we get diseases like diabetes or alzheimer's? Is it fun or sad that the nature has been eaten in the blood? All must not be determined by the genetic factor alone.

So what else? One of the most surprising basic findings in genetic research is that when conception succeeds, everything is not 'set up' as cards are dealt to players. Instead, most genes can be controlled according to the switch.

Controlling these switches will cause it to "turn on" or "turn off" (become dominant or recessive genes). And the "object" that controls these shortcuts can be affected by all our actions, from what we have been fed by our parents until we have experienced so much stress and stress.

Genius in all of us

One of the most interesting things about this new discovery is that the gene accumulation capacity is very small.

The book 'Genius in all of us' shows that we are too far away to explain intellectual abilities such as IQ or musical ability simply because of those preeminent genes.

'Of course, this does not say that genes do not play an important role. But research shows that most of us do not approach the opening of our true ability, the intelligence or the ability to play sports ., until we spend time and effort for it, ' David Shenk said.

His message is that parents show their love to children with practical action. David believes that families, schools and society should encourage more children to develop their abilities even further.

'IQ can change if people are encouraged right,' he stressed.

So what can boost genes in the right direction or deviate?

As well as positive and negative forms of teaching, things that can affect genes are diet, exercise, stress, cigarettes, pesticides and chemicals. Thus the gene is not only affected by the brain but also influenced by lifestyle and behavior. Therefore, we can 'turn on' or 'turn off' but genes are associated with obesity and disease.

For example, omega-3 fatty acids found in fish oil can affect more than 100 genes; While a high-carbohydrate diet is 'triggering' genes associated with infection, according to a diet study, more protein and fat are needed.

Lifestyle can affect genes associated with Alzheimer's disease. One of the biggest mysteries for scientists is why people have plaques and disturbances in the brain, signs of illness, and never influenced by any emotion. Or what mental factor?

Dr. Daivd Bennett, director of the Alzheimer's Center at Rush University Medical Center (USA) thinks he has found the answer: He is studying genes on brain cells of dead people that, when examined, the brain contains Full of plaque and mess. 'We found that people without Alzheimer's symptoms had a different point in' turning 'on key gene switches. And we also found some other things. Most people who have no symptoms can keep their mind and alertness intact. "

It may be true that the development of plaque and disorders depends on the gene but the symptoms such as dementia, alzheimer's anxiety depend on life experience and this is the gene regulation.

Experience is not a cure, but it explains why the lifestyle has an impact.

So what 'turn' - 'off' gene switch?

Scientists have long known that there must be something that affects the gene, 'on' or 'off' and that is the epigenetic mechanism (changes in gene expression that are not related to genetically modified but can still be passed on to the next generation.

This epigenetic mechanism is particularly strong in the stage of fetal development. Immediately after the sperm meets the egg, embryonic cells have developed rapidly into hundreds of types of cells, creating the body. Epigenetic mechanisms ensure that only the genes needed for each cell type are active.

According to Dr. Jonathan Mill, London Research Institute of Psychiatry, genes are most vulnerable at the time before and after birth. 'Animal studies show that mothers with excessive exposure to alcohol, stress, smoke and poor nutrition during pregnancy and childbirth will have children with genetic mechanisms. The genetic changes in the brain (the pathogens that 'dive' become 'dominant'). This will put children at risk for disorders such as attention-deficit hyperactivity disorder (ADHD), depression and ease of addiction , 'Dr Mill said.

These findings will help screen and regulate changes in epigenetic mechanisms through medical methods. The first disease to benefit is cancer. 'Some types of melanoma may contain negative changes in epigenetic mechanisms. And the new idea is to change them in a positive way with drugs. For example, genes that are responsible for eliminating malignant cells will often be 'turned off' causing malignant cells to proliferate. And there will be 'stimulating' drugs for these genes to 'start'.

Most notably, the most powerful effect of epigenetic mechanisms is on the next generation. The genes that you press the 'off' button with stress, with the love of the mother and the low-carbohydrate diet . can affect children.

Last year, researchers at the University of Massachusetts reported giving toys and concentration to improve memory. When these mice mate with mice that live in rich habitats, their children are also smarter.
