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 provides 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 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 that are not detected by regular testing and that could cause severe health problems.
Like all living systems, cells are constantly changing and grow, divide and die. All cells need a constant supply of energy, and this process is initiated by a process referred to as”mimetic induction”. Through natural selection, favorable 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 on between generations and decides how cells in one 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 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. By way of 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 these 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 then binds to the hair follicles, making 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, since there are other genetic and environmental 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 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. In particular, Epigenetic’s Science goes into detail about the impact that diet has on mice, worms, 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 suggestive of insulin resistance. In another experiment, the lab 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 happening here, you have to take a look at the Epigenetic’s Science methodology. Fundamentally, they’re growing yeast in lab 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 cases like this, the creation of cells has been used to study insulin resistance, something that we humans have.
Of course, there are other 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’re attempting to treat Alzheimer’s disease in mice. As exciting as that may seem, it is not your everyday normal cancer therapy. 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 types of diseases and ailments, 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 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 very own drug factory!
