Epigenetic’s Science is composed by award winning writer, Raoul Pedretta. Great 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 own bodies and minds – some unsettling, some comforting. The premise 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 illnesses as cancer, Alzheimer’s disease and Parkinson’s. They also describe the surprising effect of”epigenetic pollution,” environmental contaminants which aren’t detected by regular testing and that could cause severe health problems.
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 if 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 may be a whole gamut of changes on the cell surface and in the biochemical pathways within 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 instance, 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 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 in turn, 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 a condition called”male pattern baldness.” Interestingly, this is not 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 might shed 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 concerning the effect that diet has on rats, rodents, 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 lab animals also lost muscle mass, which is suggestive of insulin resistance. In another experiment, the lab animals were put on a particular sort of diet where they only received food that 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. Fundamentally, they’re growing yeast in lab 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 cases like this, the generation of cells was used to study insulin resistance, something that we humans possess.
Needless to say, there are additional Epigenetic’s Science techniques that they use, including gene regulation and the study of cancerous tumors. In actuality, they’ve recently launched a successful clinical trial where they’re trying to treat Alzheimer’s disease in mice. As exciting as that may sound, it’s 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 very small so we do not 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 could be able to grow your own cells for immune system support and energy production; essentially creating your very own drug factory!
