Stress has become an inseparable part of our daily lives. Whether it is work stress, family stress, relationship stress or any manifestation of the same. Are you able to handle it though? If your answer is ‘No’, then blame it on your genetic makeup.
As published in a study which featured in the Journal of Molecular Psychiatry, the inability of handling stressful situations in your day to day life may not be a fault of the situation but your internal alma matter.
Is Your Genetic Make-Up Stressing You Out? Maybe So
Researchers from Rockefeller University in the US conducted studies that have been able to show a genetic disposition to one’s inability to handle and manage stress. The findings could lead researchers to understand better the development of psychiatric disorders such as anxiety and depression and the consequent development of new treatments for these devastating disorders.
The Stressful Research model
The researchers used mouse models for the study. These mice were induced to chronic stress by exposing them to daily, unpredictable conditions they dislike with the goal of reproducing the sort of stressful experiences which act as causal factors for the onset of depression in humans.
The researchers found that the highly stress-susceptible mice had less of an important molecule known as mGlu2 in a region of the brain known as the hippocampus.
The mGlu2 decrease was found to be a result of a genetic change, which affects the expression of genes, in this case, the gene that codes for mGlu2.
In simple words, the genetic code can be thought as words in a book which must be read in order to produce a particular protein in the body. However, a genetic change effectively closes the book, so the code for the protein, in this case, mGlu2 cannot be read, explained the first author Carla Nasca from the Rockefeller University.
What is mGlu2 and Why is it important?
• mGlu2 stands for Metabotropic Glutamate Receptor 2.
• It is important as it regulates the neurotransmitter, glutamate, in our brains.
• Glutamate functions as the brains main excitatory neurotransmitter and are important for neuronal communication, memory formation, learning, and regulation.
• Although crucial for relaying of messages in the brain, glutamate in excess can lead to harmful structural changes in the brain.
