Vitamins A and C aren’t just good for your health, they affect your DNA too. Researchers have discovered how vitamins A and C act to modify the epigenetic ‘memory’ held by cells; insight which is significant for regenerative medicine and our ability to reprogramme cells from one identity to another.
The children of traumatized people have long been known to be at increased risk for posttraumatic stress disorder (PTSD), and mood and anxiety disorders. However, there are very few opportunities to examine biologic alterations in the context of a watershed trauma in exposed people and their adult children born after the event.
A new study on the epigenetics of lactose intolerance may provide an approach to understanding schizophrenia and other complex, serious illnesses. While that may seem odd, both lactose intolerance and schizophrenia are inherited. In addition, neither condition emerges in the first years of life, but rather both appear years or even decades later.
The rise of underage drinking has almost left a sense that it is acceptable or even free of long-term consequences. Unfortunately because the brain continues forming long into the early twenties, environmental factors can have a large impact on the development. In fact, research shows that binge-drinking during adolescence may perturb brain development at a critical time and leave lasting effects on genes and behavior that persist into adulthood.
Cancers are alive in a sense, they are similar to a parasite and they fight to stay alive when we just want them gone. Cancers have access to complex ways of avoiding elimination and because we cannot easily do anything to treat it short of surgery or chemotherapy, we regularly lose to some of the more cunning types. Now researchers have learned how living beings can keep gene expression in check — this might partly explain the uncontrolled gene expression found in many forms of cancer.
No one likes to talk about eating disorders — specifically anorexia nervosa — despite the increased prevalence in both men and women. Like depression people tend to think that you can “just get over it” or some other nonsense. However new research is shedding light on the truth behind anorexia, much like with depression, there is a biological component involved. Simply put, it gets written into your genes.
Despite what you may think, the supposed “explosion” of children diagnosed with autism can directly attributed to better diagnosing techniques and — more importantly — the change of definition to make Autism spectrum disorders more broad. Thankfully more causes of autism have been found, none of them remotely related to vaccines and now scientists have found that chemical modifications to DNA’s packaging—known as epigenetic changes—can activate or repress genes involved in autism spectrum disorders (ASDs) and early brain development.
Telomere length is associated with aging, this isn’t a new statement, but interestingly enough there is more to this story than just the size of your telomeres. Telomere lengths have now been shown to cause epigenetic changes, this new discovery may help explain the aging of cells and how they initiate and transmit disease.
When I try to explain epigenetics to someone, I like to use the musician metaphor. Your genes are the sheet music and how your body reads those genes, that is your body acting like a musician, making those notes it’s own. This is even more evident when you realize that all human cells contain essentially the same DNA sequence. Up until now we’ve had to be the audience to this genetic symphony, but new research is helping scientists take control of the music.
Why is it that when you break a bone, it heals, but when something happens to your spinal cord, the nerves don’t repair themselves? A new study in the Journal of Nature Communications now helps shed some light on just why that is.
But first a little background, the nervous system is made up of two separate parts, your central nervous system [CNS] which is made up of your brain and spinal cord, everything else is called the peripheral nervous system [PNS].
