Epigenetic’s Science is composed 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 new insights into our own bodies and minds – some unsettling, some comforting. The premise of Epigenetic’s Science is 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 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 can 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 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 type of cellular memory, or methylation state. This methylation state is passed between generations and decides how cells in one family will act 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 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 physically. There are many ways in which Epigenetic’s Science presents the science of Epigenetics. By way of example, each chapter contains an informative section addressing one of the most common Epigenetic changes which occur 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 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, 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 affected by methylation, so future study might shed even 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 concerning the impact that diet has on rats, rodents, and other organisms. To begin 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 lab animals also lost muscle mass, which is indicative of insulin resistance. In another experiment, the lab animals were put on a particular sort of diet where they just received food which contained carbohydrates; they lost body weight fairly quickly.
In order to understand what’s going on here, you must have 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 is going to replicate and thus create a new generation of yeast cells. In this case, the creation of cells has been 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 actuality, they have recently established a successful clinical trial in which they are trying to treat Alzheimer’s disease in mice. As exciting as that may seem, it is not your everyday normal cancer treatment. This study shows they are able to manipulate and regulate cells and halt the growth of cancerous tumors.
Besides diabetes, Epigenetic’s Science may 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 be able to grow your own cells for immune system support and energy generation; essentially creating your own drug factory!
