Epigenetic’s Science is composed by award winning writer, Raoul Pedretta. Good 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 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 lead to such illnesses as cancer, Alzheimer’s disease and Parkinson’s. They also clarify the surprising effect of”epigenetic pollution,” environmental contaminants that aren’t detected by standard testing and that can cause serious health problems.
Like all living systems, cells are constantly changing and grow, divide and die. All cells need a continuous 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 determines how cells in 1 family will act in response to environmental challenges and how those cells will respond 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 results in 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. By way of example, each chapter includes an informative section covering among the most frequent Epigenetic changes which exist in all of us: puberty. The chapters include;”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 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 isn’t 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 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 start with, one interesting finding was that when the worm C. elegans was 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 is happening here, you must take a look at the Epigenetic’s Science methodology. Fundamentally, 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 generation of yeast cells. In this case, the creation of cells was used to study insulin resistance, something that we humans have.
Of course, there are additional Epigenetic’s Science techniques they use, including gene regulation and the study of cancerous tumors. In fact, they’ve recently launched a successful clinical trial in which they are attempting to treat Alzheimer’s disease in mice. As exciting as that may seem, it’s not your regular normal cancer treatment. This study shows that they are able to control and regulate cells and halt the growth of cancerous tumors.
Besides 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 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 might have the ability to grow your own cells for immune system support and energy production; essentially creating your very own drug factory!
