Epigenetic’s Science is written 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 comforting. The assumption of Epigenetic’s Science is that environmental exposures can have long lasting effects on cellular function. Some of these effects are not so 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 clarify the surprising effect of”epigenetic pollution,” environmental contaminants which are not detected by standard testing and that can cause serious health problems.
Like all living systems, cells are constantly changing and grow, divide and die. All cells need a constant supply of energy, and this procedure 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 determines how cells in 1 family will act in response to environmental challenges and how those cells will respond when similar challenges arise in a different 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 response on the body. There are a number of ways in which 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 occur in all of us: puberty. The chapters comprise;”Growthal Sensitivity,””Mutations in Birth,”” hormonal changes,””perinatal development,””adolescent-onset diabetes,” and”nutrition.” I enjoyed each of these and found them to be very 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 subsequently binds to the hair follicles, making it difficult for nutrients to reach the roots. This causes baldness in men and a condition known as”male pattern baldness.” Interestingly, this isn’t the only cause of hair loss, since there are other environmental and genetic 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 study 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 impact that diet has on mice, worms, and other organisms. To begin with, one interesting finding was that when the worm C. elegans was given a high fat diet, it became diabetic and obese. Interestingly, the laboratory 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 which contained carbohydrates; they lost body fat fairly quickly.
In order to understand what’s happening here, you must take a look at the Epigenetic’s Science methodology. Basically, they’re growing yeast in lab cultures and watching what happens. After the yeast grows to a certain point, it is going to replicate and thus create a new generation of yeast cells. In cases like this, the generation of cells was 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 fact, they’ve recently established a successful clinical trial where they are trying to treat Alzheimer’s disease in mice. As exciting as that may sound, it’s not your everyday normal cancer therapy. This study shows that they are able to manipulate and regulate cells and halt the growth of cancerous tumors.
Besides diabetes, Epigenetic’s Science can be used for other types of diseases and ailments, such as Parkinson’s, arthritis, Multiple Sclerosis, and even cancer. Needless to say, these studies are very 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 have the ability to grow your own cells for immune system support and energy production; essentially creating your own drug factory!
