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 new 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 very 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 describe the surprising effect of”epigenetic pollution,” environmental contaminants which are not detected by standard 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 referred to as”mimetic induction”. Through natural selection, positive 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 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 within the cell. This results in alterations in gene function and a corresponding reaction on the body. There are many ways that Epigenetic’s Science presents the science of Epigenetics. By way of instance, each chapter contains an informative section addressing one of the most common Epigenetic changes that exist in all of us: puberty. The chapters comprise;”Growthal Sensitivity,””Mutations in 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, 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 research might 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 impact that diet has on mice, worms, and other organisms. To begin with, one interesting finding was that when the worm C. elegans was given a high fat diet, it became diabetic and obese. Interestingly, the laboratory 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 only received food which 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 lab cultures and watching what happens. When the yeast grows to a certain point, it will replicate and thus create a new production of yeast cells. In this case, the creation of cells has been used to study insulin resistance, something that we humans have.
Needless to say, 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 established a successful clinical trial where they are attempting 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 halt the growth of cancerous tumors.
In addition to diabetes, Epigenetic’s Science may be used for other kinds 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 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 very own drug factory!
