The Science of Gene Expression
Your thoughts are things. They are actual proteins called neurotransmitters, serotonin, dopamine, adrenaline which attach to cell membranes and cause your genes to express themselves. And that expression, that gene expression is inheritable over the next few generations. So, you are not a victim of your genes, you have some control over how they are expressed.Dr. Bruce Lipton – A New Hope: Epigenetics and the Subconscious Mind.
Epigenetics is a relatively new field of study that has been gaining a lot of attention in recent years. It is the study of how genes are expressed, or turned on and off, in response to environmental factors. This means that even though we may have certain genes that predispose us to certain conditions or diseases, our environment can play a role in whether or not those genes are expressed.
The term “epigenetics” comes from the Greek word “epi,” which means “above” or “on top of.” This refers to the fact that epigenetic changes occur on top of the DNA sequence itself. These changes can be passed down from one generation to the next, but they can also be reversible.
One of the most well-known examples of epigenetics is the study of identical twins. Even though identical twins have the same DNA sequence, they can have different epigenetic profiles. This means that even though they have the same genetic predispositions, their environment can play a role in whether or not those genes are expressed.
DNA and Epigenetics
Epigenetic changes can occur in a number of ways. One of the most common ways is through DNA methylation. This is a process where a methyl group is added to a DNA molecule, which can turn off the gene that it is attached to. Another way that epigenetic changes can occur is through histone modification. Histones are proteins that help package DNA into a compact structure. Modifications to these proteins can affect how tightly the DNA is packaged, which can affect whether or not the genes are expressed.
Epigenetics has been linked to a number of different conditions and diseases. For example, studies have shown that epigenetic changes can play a role in cancer, diabetes, and heart disease. Epigenetics has also been linked to mental health conditions such as depression and anxiety.
One of the most exciting things about epigenetics is that it is reversible. This means that even if someone has a genetic predisposition to a certain condition, they may be able to prevent it from developing by making changes to their environment. For example, a healthy diet and exercise can help prevent epigenetic changes that can lead to obesity and diabetes.
