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 new insights into our own 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 are not so easy to reverse and the authors describe how”epigenetic inheritance” can result in such disorders as cancer, Alzheimer’s disease and Parkinson’s. They also clarify the surprising effect of”epigenetic pollution,” environmental contaminants which 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 require 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 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 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 within the cell. This causes alterations in gene function and a corresponding response on the body. There are many ways in which Epigenetic’s Science presents the science of Epigenetics. For example, each chapter includes an informative section addressing one of the most common Epigenetic changes that exist in all people: 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 then 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 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 influenced by methylation, so future research might shed more light on Epigenetic’s Science.
The next topic that Epigenetic’s Science touches on is the effect that diet has on the body. Specifically, Epigenetic’s Science goes into detail about the effect 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 lab animals also lost muscle mass, which is indicative 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 weight fairly quickly.
So as to understand what is happening here, you have to take a look at the Epigenetic’s Science methodology. Basically, they are growing yeast in lab 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 generation of cells has been used to study insulin resistance, something that we humans have.
Needless to say, there are other Epigenetic’s Science techniques they use, including gene regulation and the study of cancerous tumors. In fact, they have recently established a successful clinical trial in which they’re attempting to treat Alzheimer’s disease in mice. As exciting as that may sound, it’s not your regular normal cancer therapy. This study shows they are able to control and regulate cells and stop the growth of cancerous tumors.
Besides diabetes, Epigenetic’s Science may be used for other kinds of diseases and conditions, such as Parkinson’s, arthritis, Multiple Sclerosis, and even cancer. Of course, 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 be able to grow your own cells for immune system support and energy production; essentially creating your very own drug factory!
