EPIGENETICS; How We Mere Mortals Get to Play with the Immortals.

If our genes don’t seal our fate and if they actually contain an enormous library of possibilities just waiting to be taken off the shelf and read, then what gives us access to those potentials that could have a huge effect on our health and well-being?

The men in the monastery study surely gained such access, but how did they do it?

The answer lies in a relatively new field of study called epigenetics.

The word epigenetics literally means “above the gene.”

It refers to the control of genes not from within the DNA itself but from messages coming from outside the cell in other words, from the environment.

These signals cause a methyl group (one carbon atom attached to three hydrogen atoms) to attach to a specific spot on a gene, and this process (called DNA methylation) is one of the main processes that turn the gene off or on.

Epigenetics teaches that we, indeed, are not doomed by our genes and that a change in human consciousness can produce physical changes, both in structure and function, in the human body.

We can modify our genetic destiny by turning on the genes we want and turning off the ones we don’t want by working with the various factors in the environment that program our genes.

Some of those signals come from within the body, such as feelings and thoughts, while others come from the body’s response to the external environment, such as pollution or sunlight.

Epigenetics studies all of these external signals that tell the cell what to do and when to do it, looking at both the sources that activate, or turn on, gene expression (upregulating) and those that suppress, or turn off, gene expression (downregulating) as well as the dynamics of energy that adjust the process of cellular function on a moment-to-moment basis.

Epigenetics suggests that even though our DNA code never changes, thousands of combinations, sequences, and patterned variations in a single gene are possible (just as thousands of combinations, sequences, and patterns of neural networks are possible in the brain).

Looking at the entire human genome, so many millions of possible epigenetic variations exist that scientists find their heads spinning just thinking about it.

The Human Epigenome Project, begun in 2003 as the Human Genome Project drew to a close, is underway in Europe, and some researchers have said that when it’s completed, it “will make the Human Genome Project look like homework that 15th-century kids did with an abacus.”

Going back to the blueprint model, we can change the colour of what we build, the type of materials we use, the scale of the construction, and even the positioning of the structure making an almost infinite number of variations all without ever changing the actual blueprint.

A great example of epigenetics at work involves identical twins, who share the same DNA.

If we embrace the idea of genetic predeterminism the idea that all diseases are genetic then identical twins should have the same gene expression.

However, they don’t always manifest the same illnesses in the same way, and sometimes one will manifest a genetic disease that the other doesn’t manifest at all.

Twins can have the same genes, but different outcomes.

A Spanish study illustrates this perfectly. Researchers at the Cancer Epigenetics Laboratory at the Spanish National Cancer Center in Madrid studied 40 pairs of identical twins, ranging in age from 3 to 74.

They found that younger twins who had similar lifestyles and spent more years together had similar epigenetic patterns.

In comparison, older twins, in particular those with dissimilar lifestyles who spent fewer years together, had very different epigenetic patterns.

For example, researchers found four times as many differentially expressed genes between one pair of 50-year-old twins as they did between a pair of 3-year-old twins.

The twins were born with the same DNA, but those with different lifestyles (and different lives) ended up expressing their genes very differently especially as time went on.

To use another analogy, the older twin pairs were like exact copies of the same model of a computer.

The computers came loaded with some similar starter software, but as time went on, each downloaded very different additional software programs.

The computer (the DNA) stays the same, but depending on what software a person has downloaded (the epigenetic variations), what the computer does and the way it operates can be quite different.

So, when we think our thoughts and feel our feelings, our bodies respond in a complex formula of biological shifts and alterations, and each experience pushes the buttons of real genetic changes within our cells.

The speed of these changes can be truly remarkable.

In just three months, a group of 31 men with low-risk prostate cancer were able to upregulate 48 genes (mostly dealing with tumor suppression) and downregulate 453 genes (mostly dealing with tumor promotion) by following an intensive nutrition and lifestyle regimen.

The men, enrolled in a study by Dean Ornish, M.D., at the University of California at San Francisco, lost weight and reduced their abdominal obesity, blood pressure, and lipid profile throughout the study.

Ornish noted, “It is not so much about risk-factor reduction or preventing something bad from happening.

These changes can occur so quickly you don’t have to wait years to see the benefits.”

Even more impressive is the number of epigenetic changes made over six months in a Swedish study of 23 slightly overweight, healthy men who went from being relatively sedentary to attending spinning and aerobics classes an average of just under twice per week.

Researchers at Lund University discovered that the men had epigenetically altered 7,000 genes almost 30 percent of all the genes in the entire human genome!

These epigenetic variations may even be inherited by our children and then passed on to our grandchildren.

The first researcher to show this was Michael Skinner, Ph.D., who was director of the Center for Reproductive Biology at Washington State University.

In 2005, Skinner led a study that exposed pregnant rats to pesticides.

The male pups of the exposed mother rats had higher rates of infertility and decreased sperm production, with epigenetic changes in two genes.

These changes were also present in about 90 percent of the males in each of the four generations that followed, even though none of these other rats were exposed to any pesticides.

Our experiences from our external environment are only part of the story, however.

As we’ve been learning, how we assign meaning to those experiences includes a barrage of physical, mental, emotional, and chemical responses that also activate genes.

How we perceive and interpret the data we receive from our senses as factual information whether that information is true or not and the meaning we give it to produce significant biological changes on a genetic level.

Thus, our genes interact with our conscious awareness in complex relationships. We could say that meaning is continually affecting the neural structures that influence who we are on the microscopic level, which then influences who we are on the macroscopic level.

The study of epigenetics also raises the question:

What if nothing is changing in your external environment?
What if you do the same things with the same people at the same time every day things leading to the same experiences that produce the same emotions that signal the same genes in the same way?

We could say that as long as you perceive your life through the lens of the past and react to the conditions with the same neural architecture and from the same level of mind, you’re headed toward a very specific, predetermined genetic destiny.

In addition, what you believe about yourself, your life, and the choices you make as a result of those beliefs also keep sending the same messages to the same genes.

Only when the cell is ignited in a new way, by new information, can it create thousands of variations of the same gene to rewrite a new expression of proteins which changes your body.

You may not be able to control all the elements in your outer world, but you can manage many aspects of your inner world.

Your beliefs, your perceptions, and how you interact with your external environment influence your internal environment, which is still the external environment of the cell.

This means that you are not your preprogrammed biology holds the keys to your genetic destiny.

It’s just a matter of finding the right key that fits into the right lock to unleash your potential.

So why not see your genes for what they are?

Providers of possibility, resources of unlimited potential, a code system of personal commands in truth, they’re nothing short of tools for transformation, which means “changing form.”
