Epigenetic’s Science is written 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 new 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 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 that 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 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 on between generations and decides how cells in one family will behave in response to environmental challenges and how those cells will respond 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 response physically. There are many ways that Epigenetic’s Science presents the science of Epigenetics. For example, each chapter includes an informative section covering among the most frequent 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 them 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 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 influenced by methylation, so future study might 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. In particular, 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 particular sort of diet where they only received food which contained carbohydrates; they lost body weight fairly quickly.
In order to understand what’s happening here, you have to have 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 production of yeast cells. In this case, the generation of cells has been used to study insulin resistance, something that we humans possess.
Needless to say, 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 in which they are attempting to treat Alzheimer’s disease in mice. As exciting as that may seem, 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.
Besides diabetes, Epigenetic’s Science can 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’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 own drug factory!
