Memories can be inherited, and Researcher might have now figured out how
Our life experiences may be passed on to our kids and our children's kids - and now scientists report that they have Newly Find that this inheritance can be turned on or off.
Epigenetic is the study of inherited changes in gene expression... changes that are inherited, but aren't inherent to our DNA. For example, life experiences, which aren’t directly coded in human being DNA, can actually be passed on to children. Studies have shown that survivors of traumatic events may have effects in subsequent generations. This is the question that a Tel Aviv University (TAU) was seeking to reply when they reportedly discovered a mechanism that makes it possible to turn the change of environmental influences on or off.
Their research was newly published in the journal Cell, and was led by Oded Rechavi along with a team of faculty members from TAU’s Faculty of Life Sciences and Sagol School of Neuroscience.
Understanding the mechanism
According to their study, epigenetic responses that are inherited follow an active process as it gets passed on through generations.
"We previously showed that worms inherited small RNAs following the starvation and viral infections of their parents. These small RNAs helped arrange their offspring for similar hardships," Rechavi said.
He goes on the explain the research, note: "We also recognized a mechanism that amplified heritable small RNAs across generations, so the reaction was not diluted. We found that enzymes called RdRPs are required for re-creating new small RNAs to keep the response going in subsequent generations.
From there, scientists were able to determine that specific genes, which they dubbed customized Tran generational Epigenetic Kinetics (MOTEK), are too involved in turning epigenetic transmission on and off. Switching on/off are based on the feedback interaction between RNAs (which are inherited) and the MOTEK genes that are necessary to producing and transmitting the RNA through each generation.
The present study was conduct on worms, but appreciative the principles behind the process of passing on epigenetic information will ultimately lend itself to a more comprehensive theory of heredity, especially for humans Being.
