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 provides 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 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 issues.
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 referred to as”mimetic induction”. Through natural selection, favorable mutations accumulate over generations, and when 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 respond when similar challenges arise in a different household 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 on the body. There are a number of ways in which Epigenetic’s Science presents the science of Epigenetics. For instance, 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 these 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 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 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 affected by methylation, so future research may shed more light on Epigenetic’s Science.
The next topic that Epigenetic’s Science touches on is the impact that diet has on the body. In particular, 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 obese and diabetic. 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 type of diet where they only received food that contained carbohydrates; they lost body fat fairly quickly.
So as to understand what’s happening here, you must take 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 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 that they use, such as gene regulation and the study of cancerous tumors. In fact, they’ve recently launched a successful clinical trial in which they’re 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 that they are able to manipulate and regulate cells and stop the growth of cancerous tumors.
In addition to 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 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 might be able to grow your own cells for immune system support and energy generation; essentially creating your own drug factory!
