Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

In an important study for understanding how memories are made, cientists show that the flexibility of chromatin -- packaged DNA inside the cell -- plays a crucial role in 'deciding' which neurons are ...

In 2018, when the study of potentially modifiable genetic markers for sleep apnea was emerging, a group of researchers from Mexico published a study titled, “Dad’s snoring may have left molecular ...

Analysis of cheek swabs taken from pregnant women revealed a potential epigenetic biomarker for preeclampsia, a potentially life-threatening condition that often leads to preterm births. While a ...

Genes are not set in stone. Epigenetics examines how your environment and habits determine which genes are turned on or off, showing that your child’s future is shaped by more than DNA alone. In ...

Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally. This is where DNA and RNA ...

Neurons have variable levels of chromatin compaction, shown as different shades of red. The less compact a neuron, the more likely it is to be recruited into the memory trace (green). When we form a ...
