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 reassuring. The assumption of Epigenetic’s Science is 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 disorders as cancer, Alzheimer’s disease and Parkinson’s. They also describe the surprising effect of”epigenetic pollution,” environmental contaminants that 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 need a constant supply of energy, and this process 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 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 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 inside the cell. This causes alterations in gene function and a corresponding response on the body. There are a number of ways in which Epigenetic’s Science presents the science of Epigenetics. For instance, each chapter includes an informative section covering among the most frequent Epigenetic changes which 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 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 then binds to the hair follicles, which makes it difficult for nutrients to reach the roots. This causes baldness in a condition known as”male pattern baldness” Interestingly, this is not 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 affected by methylation, so future research may 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 effect that diet has on mice, worms, and other organisms. To start with, one interesting finding was that when the worm C. elegans was given a high fat diet, it became diabetic and obese. Interestingly, the laboratory animals also lost muscle mass, which is indicative of insulin resistance. In another experiment, the lab animals were put on a special type of diet where they only received food that contained carbohydrates; they lost body weight fairly quickly.
So as to understand what’s going on here, you have to 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 is going to replicate and thus create a new generation of yeast cells. In this case, the generation 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, such as gene regulation and the study of cancerous tumors. In actuality, they have recently established a successful clinical trial where they’re trying to treat Alzheimer’s disease in mice. As exciting as that may sound, it’s not your everyday normal cancer treatment. This study shows they are able to manipulate and regulate cells and stop the growth of cancerous tumors.
In addition to diabetes, Epigenetic’s Science can be used for other types of diseases and conditions, such as Parkinson’s, arthritis, Multiple Sclerosis, and even cancer. Of course, these studies are extremely small so we don’t 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 could have the ability to grow your own cells for immune system support and energy production; essentially creating your own drug factory!
