Epigenetic’s Science is written by award winning author, 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 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 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 regular testing and that can cause serious 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 process is initiated by a process called”mimetic induction”. Through natural selection, positive 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 decides how cells in one family will behave in response to environmental challenges and how those cells will react 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 within the cell. This results in 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 covering among the most common Epigenetic changes that 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 quite 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, which makes it difficult for nutrients to reach the roots. This causes baldness in a condition called”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 affected by methylation, so future study 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 about the impact 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 laboratory animals also lost muscle mass, which is indicative of insulin resistance. In another experiment, the laboratory animals were put on a special type of diet where they only received food which contained carbohydrates; they lost body weight fairly quickly.
In order to understand what is going on here, you must take a look at the Epigenetic’s Science methodology. Fundamentally, they’re 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 cases like this, the creation of cells has been used to study insulin resistance, something that we humans possess.
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 where they are attempting to treat Alzheimer’s disease in mice. As exciting as that may sound, it’s not your regular normal cancer treatment. This study shows they are able to control and regulate cells and halt the growth of cancerous tumors.
Besides diabetes, Epigenetic’s Science may be used for other kinds of diseases and ailments, such as Parkinson’s, arthritis, Multiple Sclerosis, and even cancer. Of course, these studies are very small so we don’t 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 could be able to grow your own cells for immune system support and energy generation; essentially creating your very own drug factory!
