Articles that explore the ways in which epigenetic drugs may be used to stave off cancer and other diseases. Additional articles cover topics related to drug abuse, rehab, and addiction.
Addiction has become an epidemic that is sweeping not only the nation, but the whole world. Returning substance abusers develop an emotional connection to a situation, environment or people that are present at the time of first usage, which generally means that when they encounter a similar experience, they look to use again. Kicking an addiction and all its symptoms may be one of the hardest things that a human has to endure. Half the battle is stopping use of [more…]
Scientists from the National Institutes of Health (NIH) and Johns Hopkins Medicine worked together to analyze human and mouse epigenomes and discovered that drinking alcohol could lead to epigenetic changes that influence a particular gene’s ability to regulate cholesterol. The results suggest an underlying epigenetic mechanism known as DNA methylation could explain why someone’s body processes cholesterol differently depending on their drinking habits. It also offers unique insight into the effects of cholesterol-lowering drugs which are commonly used to reduce [more…]
You can now add “harmful changes to your DNA” to the long list of reasons to quit smoking cigarettes, along with lung cancer, coronary heart disease, increased risk of death, stroke, chronic lung disease, decreased immune function, infertility, and the fact that smoking harms nearly every organ in the body. Researchers at the Johns Hopkins Kimmel Cancer Center recently contributed to the growing evidence that demonstrates that smoking cigarettes – which contain a deadly cocktail of over 7,000 chemicals – [more…]
A recent discovery out of St. Jude’s Children’s Research Hospital finds an epigenetic cause to why T-cells fall ineffective in immune responses to cancer and viral infections. T-cells, a type of cell produced by the thymus gland, are a critical combatant in the human immune system. Their main job is to fight foreign invaders such like viruses or cancers by detecting certain proteins on the surface of the intruder cell. Cancer cells often carry normal proteins which can trick the [more…]
Aging and mortality has been a fascinating topic of interest recently, particularly in the field of epigenetics. What are the chemical DNA markers of age? Can we look at someone’s epigenome to determine their risk for death? Could we reverse these epigenetic tags to restore youth or undo the pesky physical characteristics and diseases that come with getting old? And are there lifestyle changes we may need to make to epigenetically improve our own health? Although we are far from [more…]
For a long time humans have wondered if chemicals causing drug and alcohol addiction could be active in the genes and potentially passed on to the next generation. Although this was not scientifically proven until recent years, the fear of suffering from addictive diseases led children of addicts and former addicts to avoid alcohol and drugs completely. One of the scientific studies that give weight to this family history hypothesis on addiction was conducted at the Indiana University School of [more…]
not only harms your brain and body, but may also epigenetically impact your future children, a new study reports. Excessive drinking in adolescents could turn genes on or off in their offspring’s brain, setting them up for susceptibility to certain diseases. The study, presented at the annual Society for Neuroscience meeting on Nov. 14, 2016, suggests that repeated episodes of excessive drinking when you’re young can actually put your future children at risk for developing disorders such as anxiety, depression, [more…]
Not only does cigarette smoke severely harm the body, it also leaves behind long-lasting damage on DNA, according to a recent study. An unwanted surplus of chemical marks are added to specific spots on the genome of a smoker, which may give rise to diseases such as a cancer, cardiovascular and lung disorders, and osteoporosis. A group of international researchers conducted a large scale meta-analysis of genome-wide DNA methylation, pulling data from nearly 16,000 people. Around 15% of participants were [more…]
Why are some people more vulnerable to drug addiction than others? Why is it possible for a person to use a drug once and be able to put it down forever, whereas another person becomes hooked and cannot stay clean, no matter how hard they try? These questions are far from being completely understood, and the answers may lie in several different factors, including environmental, societal, and genetic. Yet, understanding the interplay among these factors is difficult, since they vary [more…]
Thankfully, smoking is a habit all pregnant women are advised to break. But, surprisingly, this wasn’t always the case, especially in the 1940s and 1950s when doctors endorsed smoking in tobacco advertisements. Tobacco companies even ran ads hinting that pregnant women could smoke as a way to calm their nerves. With the influx of research on the harms of cigarettes, it now seems absurd to think they were ever recommended. A recent study in American Journal of Human Genetics links [more…]
