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 offers 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 are not very 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 describe the surprising effect of”epigenetic pollution,” environmental contaminants which are not detected by standard testing and that can cause severe health issues.
Like all living systems, cells are constantly changing and grow, divide and die. All cells need a constant supply of energy, and this process is initiated by a process called”mimetic induction”. Through natural selection, favorable 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 on between generations and decides how cells in 1 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 within the cell. This results in alterations in gene function and a corresponding response on the body. There are many ways in which Epigenetic’s Science presents the science of Epigenetics. For example, each chapter contains an informative section covering among the most frequent Epigenetic changes that 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 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 is not the only cause of hair loss, as 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 about the effect that diet has on mice, worms, and other organisms. To begin with, one interesting finding was that when the worm C. elegans has been given a high fat diet, it became obese and diabetic. Interestingly, the lab animals also lost muscle mass, which is indicative of insulin resistance. In another experiment, the laboratory animals were put on a particular sort of diet where they only received food that contained carbohydrates; they lost body fat fairly rapidly.
In order to understand what is going on here, you have to have a look at the Epigenetic’s Science methodology. Basically, 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 cases like this, the generation of cells was used to study insulin resistance, something that we humans have.
Of course, there are other Epigenetic’s Science techniques they use, such as gene regulation and the study of cancerous tumors. In fact, they’ve recently launched a successful clinical trial where they are attempting to treat Alzheimer’s disease in mice. As exciting as that may sound, it’s not your regular normal cancer therapy. This study shows that they are able to manipulate and regulate cells and halt the growth of cancerous tumors.
In addition to diabetes, Epigenetic’s Science can be used for other kinds of diseases and conditions, 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 generation; essentially creating your own drug factory!
