Moms Exposed to Lead May Impact DNA Methylation of Her Children and Grandchildren

November 24, 2015 Bailey Kirkpatrick

Evidence supporting multigenerational epigenetic inheritance continues to mount as a group of researchers discover that mothers who have a significant amount of lead present in their blood can epigenetically impact not only their unborn children, but their grandchildren as well. The study was published in Scientific Reports. It is well known that children in the womb can be impacted by small amounts of exposure to lead. If a woman is pregnant and exposed to lead, it can harm the baby [more…]

The Epigenetics Behind the Flu

November 17, 2015 Natalie Crowley

When the flu hits, it typically hits hard and fast. At first, you might only notice a slight cough and some sniffles and then, before you know it, you’re unable to get out of bed. The fever, sore throat, chills, muscle aches, and overall exhaustion take over your body and you’re done for — at least for a few days, if you’re lucky. Influenza (aka “the flu”) is a dreadful virus that’s seriously contagious and seemingly unavoidable for some. In [more…]

Researchers Reveal Why Some Cancers Override HDAC Inhibitor Drugs

November 10, 2015 Bailey Kirkpatrick

UK scientists from The University of Birmingham have discovered how certain cancer cells can adapt and render cancer drugs ineffective. These drugs, known as histone deacetylase (HDAC) inhibitors, are designed to disrupt cancer cells’ genetic controls. Their research, published in Epigenetics and Chromatin, may help create new therapies focused on preventing tumors from overcoming HDAC inhibitors (HDACi). Genes can be switched on or off via molecular tags that attach to DNA and transfer signals to tell the cell how to [more…]

Epigenetics: Avoiding the Pull of Pseudoscientific Nonsense

November 3, 2015 Bailey Kirkpatrick

Serious concerns have been raised recently regarding the widespread misuse of the hot new term “epigenetics,” particularly by self-proclaimed gurus or, if you prefer, “legion purveyors of flapdoodle.” Some claim that, with the power of your mind, you can epigenetically cure or develop cancer, that positive thoughts can actually relax and lengthen DNA strands, or that happiness sits in reserves on your DNA eagerly waiting to spring to life at the command of your beliefs, emotions, and behavior! In general, [more…]
