Epigenetic’s Science is written 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 provides a veritable cornucopia of fresh insights into our own 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 result in such illnesses as cancer, Alzheimer’s disease and Parkinson’s. They also clarify the surprising effect of”epigenetic pollution,” environmental contaminants which aren’t detected by regular testing and that can cause severe 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 procedure is initiated by a process referred to as”mimetic induction”. Through natural selection, positive 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 decides how cells in 1 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 on the body. There are a number of ways that Epigenetic’s Science presents the science of Epigenetics. By way of example, each chapter contains an informative section covering among the most common Epigenetic changes that occur in all people: puberty. The chapters include;”Growthal Sensitivity,””Mutations at 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 a condition called”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 even more light on Epigenetic’s Science.
The next topic that Epigenetic’s Science touches on is the impact that diet has on the body. Specifically, Epigenetic’s Science goes into detail about the impact that diet has on mice, worms, 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 diabetic and obese. Interestingly, the lab animals also lost muscle mass, which is suggestive of insulin resistance. In another experiment, the laboratory animals were put on a special type of diet where they just received food which contained carbohydrates; they lost body fat fairly rapidly.
In order to understand what is happening here, you have to take a look at the Epigenetic’s Science methodology. Fundamentally, they’re growing yeast in laboratory cultures and watching what happens. When the yeast grows to a certain point, it is going to replicate and thus create a new production 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 other Epigenetic’s Science techniques that they use, such as gene regulation and the analysis of cancerous tumors. In actuality, they’ve recently established 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 everyday normal cancer treatment. 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 can 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’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!
