Epigenetic’s Science is composed by award winning writer, 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 offers a veritable cornucopia of fresh insights into our own 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 are not very easy to reverse and the authors describe how”epigenetic inheritance” can lead to such disorders as cancer, Alzheimer’s disease and Parkinson’s. They also describe the surprising effect of”epigenetic pollution,” environmental contaminants that aren’t detected by regular testing and that can cause serious health issues.
Like all living systems, cells are constantly changing and grow, divide and die. All cells require a constant supply of energy, and this procedure is initiated by a process referred to as”mimetic induction”. Through natural selection, positive mutations accumulate over generations, and when they get together, these cells form a sort of cellular memory, or methylation state. This methylation state is passed between generations and determines how cells in one family will act in response to environmental challenges and how those cells will react when similar challenges arise in a different household member.
When methylation is induced in a cell, the result can be a whole gamut of changes on the cell surface and in the biochemical pathways inside the cell. This causes alterations in gene function and a corresponding response physically. There are many ways in which Epigenetic’s Science presents the science of Epigenetics. For example, each chapter includes an informative section addressing one of the most frequent Epigenetic changes which occur in all of us: puberty. The chapters include;”Growthal Sensitivity,””Mutations in Birth,”” hormonal changes,””perinatal development,””adolescent-onset diabetes,” and”nutrition.” I enjoyed each of them 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 in turn, produces DHT (which stands for”dihydrotestosterone”). DHT subsequently binds to the hair follicles, which makes it difficult for nutrients to reach the roots. This causes baldness in men and a condition called”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 impact that diet has on the body. Specifically, Epigenetic’s Science goes into detail concerning the effect that diet has on rats, rodents, and other organisms. To start with, one interesting finding was that when the worm C. elegans was given a high fat diet, it became obese and diabetic. Interestingly, the lab animals also lost muscle mass, which is suggestive of insulin resistance. In another experiment, the lab animals were put on a special type of diet where they just received food that contained carbohydrates; they lost body fat fairly quickly.
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. When the yeast grows to a certain point, it will replicate and thus create a new production of yeast cells. In this case, the generation of cells was used to study insulin resistance, something that we humans have.
Of course, there are additional Epigenetic’s Science techniques they use, including gene regulation and the study of cancerous tumors. In fact, they have recently launched a successful clinical trial where they are trying to treat Alzheimer’s disease in mice. As exciting as that may seem, it is not your regular normal cancer therapy. This study shows they are able to control and regulate cells and stop the growth of cancerous tumors.
In addition to diabetes, Epigenetic’s Science may be used for other kinds of diseases and ailments, such as Parkinson’s, arthritis, Multiple Sclerosis, and even cancer. Of course, these studies are extremely small so we don’t have much of a sense of what they will mean for human health. Still, it is an exciting and very promising prospect. Just think, one day you might be able to grow your own cells for immune system support and energy production; essentially creating your very own drug factory!
