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 offers a veritable cornucopia of new insights into our 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 very 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 can cause serious health problems.
Like all living systems, cells are constantly changing and grow, divide and die. All cells require a continuous supply of energy, and this procedure is initiated by a process called”mimetic induction”. Through natural selection, favorable mutations accumulate over generations, and when 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 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 causes alterations in gene function and a corresponding reaction physically. There are a number of ways that Epigenetic’s Science presents the science of Epigenetics. For instance, each chapter contains an informative section addressing one of 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 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, 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 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 laboratory animals also lost muscle mass, which is suggestive of insulin resistance. In another experiment, the lab animals were put on a special sort 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 have 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 is going to replicate and thus create a new generation of yeast cells. In cases like this, the creation of cells was used to study insulin resistance, something that we humans possess.
Of course, there are other Epigenetic’s Science techniques they use, such as gene regulation and the analysis of cancerous tumors. In fact, they have recently launched a successful clinical trial in which they are trying to treat Alzheimer’s disease in mice. As exciting as that may sound, it is not your everyday 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 can be used for other types of diseases and conditions, such as Parkinson’s, arthritis, Multiple Sclerosis, and even cancer. Needless to say, these studies are very small so we do not 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 production; essentially creating your own drug factory!
