Epigenetic’s Science is written 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 fresh insights into our own 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 disorders as cancer, Alzheimer’s disease and Parkinson’s. They also describe the surprising effect of”epigenetic pollution,” environmental contaminants which aren’t detected by standard testing and that could cause serious 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 process is initiated by a process called”mimetic induction”. Through natural selection, positive 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 determines how cells in 1 family will behave 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 reaction on the body. There are a number of ways that Epigenetic’s Science presents the science of Epigenetics. For example, each chapter includes an informative section covering among the most frequent 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 in turn, produces DHT (which stands for”dihydrotestosterone”). DHT subsequently 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 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 influenced 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. In particular, Epigenetic’s Science goes into detail about the impact that diet has on rats, rodents, and other organisms. To start with, one interesting finding was that when the worm C. elegans was 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 laboratory animals were put on a special type of diet where they just received food which contained carbohydrates; they lost body weight fairly rapidly.
So as to understand what is going on here, you have to have a look at the Epigenetic’s Science methodology. Basically, 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 generation of yeast cells. In cases like this, the generation of cells has been used to study insulin resistance, something that we humans possess.
Needless to say, there are additional Epigenetic’s Science techniques that they use, such as gene regulation and the analysis of cancerous tumors. In actuality, they’ve recently launched a successful clinical trial in which they are 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 manipulate and regulate cells and halt the growth of cancerous tumors.
Besides diabetes, Epigenetic’s Science may 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 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 might be able to grow your own cells for immune system support and energy production; essentially creating your very own drug factory!
