Epigenetic’s Science is written by award winning author, Raoul Pedretta. Good bye, genetically encoded genes… the first book in the exciting new field of epigenetic biology for general readers. The surging new science of epigenetic genetics provides a veritable cornucopia of fresh insights into our bodies and minds – some unsettling, some reassuring. The premise of Epigenetic’s Science is the fact that environmental exposures can have long lasting effects on cellular function. Some of these effects aren’t so easy to reverse and the authors describe how”epigenetic inheritance” can result in such illnesses as cancer, Alzheimer’s disease and Parkinson’s. They also clarify the surprising effect of”epigenetic pollution,” environmental contaminants which aren’t detected by regular testing and that could cause serious health issues.
Like all living systems, cells are constantly changing and grow, divide and die. All cells need a continuous supply of energy, and this process is initiated by a process called”mimetic induction”. Through natural selection, positive mutations accumulate over generations, and if they get together, these cells form a type of cellular memory, or methylation state. This methylation state is passed between generations and decides how cells in one family will act in response to environmental challenges and how those cells will react when similar challenges arise in another household member.
When methylation is induced in a cell, the result may be a whole gamut of changes on the cell surface and in the biochemical pathways inside the cell. This results in alterations in gene function and a corresponding reaction physically. There are a number of ways that Epigenetic’s Science presents the science of Epigenetics. For example, each chapter contains an informative section addressing one of the most common Epigenetic changes that exist in all of us: puberty. The chapters comprise;”Growthal Sensitivity,””Mutations at Birth,”” hormonal changes,””perinatal development,””adolescent-onset diabetes,” and”nutrition.” I enjoyed each of these and found them to be quite interesting and educational.
As you know, during adolescence, the body increases its production of estrogen (in anticipation of future pregnancy), and then, produces DHT (which stands for”dihydrotestosterone”). DHT then binds to the hair follicles, which makes it difficult for nutrients to reach the roots. This causes baldness in a condition known as”male pattern baldness” Interestingly, this isn’t the only cause of hair loss, as there are other genetic and environmental factors that contribute to hair loss. Epigenetic science goes a step further and suggests that these other causes of hair loss may also be affected by methylation, so future research may shed even more light on Epigenetic’s Science.
The next topic that Epigenetic’s Science touches on is the effect that diet has on the body. Specifically, Epigenetic’s Science goes into detail about the impact that diet has on mice, worms, and other organisms. To start with, one interesting finding was that when the worm C. elegans has been given a high fat diet, it became diabetic and obese. Interestingly, the lab animals also lost muscle mass, which is suggestive of insulin resistance. In another experiment, the laboratory animals were put on a special sort of diet where they only received food that contained carbohydrates; they lost body fat fairly rapidly.
So as to understand what is going on here, you have to take a look at the Epigenetic’s Science methodology. Fundamentally, they are growing yeast in laboratory cultures and watching what happens. After the yeast grows to a certain point, it will replicate and thus create a new generation of yeast cells. In this case, the generation of cells has been used to study insulin resistance, something that we humans possess.
Of course, there are additional Epigenetic’s Science techniques they use, such as gene regulation and the study of cancerous tumors. In actuality, they have recently established a successful clinical trial where they are trying to treat Alzheimer’s disease in mice. As exciting as that may seem, it’s not your regular normal cancer treatment. This study shows that they are able to manipulate and regulate cells and stop the growth of cancerous tumors.
Besides diabetes, Epigenetic’s Science can be used for other types of diseases and conditions, such as Parkinson’s, arthritis, Multiple Sclerosis, and even cancer. Needless to say, these studies are very small so we do not have much of a sense of what they will mean for human health. Still, it’s an exciting and very promising prospect. Just think, one day you might have the ability to grow your own cells for immune system support and energy generation; essentially creating your very own drug factory!
