Epigenetic’s Science is written by award winning author, 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 comforting. The premise of Epigenetic’s Science is the fact that environmental exposures can have long lasting effects on cellular function. Some of these effects aren’t so easy to reverse and the authors describe how”epigenetic inheritance” can result in 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 standard testing and that can cause severe 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 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 type of cellular memory, or methylation state. This methylation state is passed on between generations and determines how cells in 1 family will behave in response to environmental challenges and how those cells will react when similar challenges arise in another family 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 a number of ways that 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 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 then, 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 a condition known as”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 influenced by methylation, so future research might 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 rats, rodents, 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 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 type of diet where they just received food which contained carbohydrates; they lost body fat fairly quickly.
In order to understand what’s going on here, you have to take a look at the Epigenetic’s Science methodology. Basically, they are growing yeast in lab cultures and watching what happens. When the yeast grows to a certain point, it will replicate and thus create a new generation of yeast cells. In this case, the generation of cells has been used to study insulin resistance, something that we humans possess.
Of course, there are additional Epigenetic’s Science techniques that they use, such as gene regulation and the analysis of cancerous tumors. In fact, they’ve recently launched a successful clinical trial in which they are trying to treat Alzheimer’s disease in mice. As exciting as that may seem, it is not your everyday normal cancer treatment. This study shows they are able to manipulate and regulate cells and stop the growth of cancerous tumors.
In addition to diabetes, Epigenetic’s Science may be used for other types 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 could be able to grow your own cells for immune system support and energy generation; essentially creating your own drug factory!
