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 offers a veritable cornucopia of new insights into our bodies and minds – some unsettling, some comforting. The assumption 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 illnesses as cancer, Alzheimer’s disease and Parkinson’s. They also describe the surprising effect of”epigenetic pollution,” environmental contaminants that are not 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 constant supply of energy, and this procedure is initiated by a process referred to as”mimetic induction”. Through natural selection, favorable mutations accumulate over generations, and if 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 1 family will act in response to environmental challenges and how those cells will respond when similar challenges arise in a different 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 inside the cell. This causes alterations in gene function and a corresponding reaction physically. There are many ways in which Epigenetic’s Science presents the science of Epigenetics. For instance, each chapter contains an informative section addressing one of the most common Epigenetic changes which occur in all people: puberty. The chapters comprise;”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 in turn, 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 a condition known as”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 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 effect 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 lab 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 just received food that contained carbohydrates; they lost body fat fairly rapidly.
In order to understand what’s happening here, you must have a look at the Epigenetic’s Science methodology. Fundamentally, 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 production of yeast cells. In this case, the generation of cells was used to study insulin resistance, something that we humans have.
Of course, there are additional Epigenetic’s Science techniques they use, such as gene regulation and the analysis of cancerous tumors. In actuality, they have recently established 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 everyday normal cancer treatment. This study shows that 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 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 own drug factory!
