Stress produces changes in the expression of our DNA, the deoxyribonucleic acid material that determines what we inherit from our parents. Our genetic material nicely stores information that has ...

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how ...

Stress affects up to 90 percent of people, and we know it harms our mental and physical well-being. Stress can impact the activity and function of our genes. It does this via “epigenetic” changes, ...

Some DNA repair enzymes can relocate to the part of the cell that needs their help, a team of scientists has found. The signal that prompts relocation is oxidative stress, an imbalance of cellular ...

DNA stores all of the information necessary for life phenomena, and a cell transmits its own genetic information to two daughter cells through DNA replication and cell division. Replication stress can ...

We’ve long known the short-term effects of trauma — headaches, changes in appetite or sleep, fear, anxiety and concentration troubles are just a few. A new study suggests that severe trauma, like that ...

Replication is a highly regulated process that guarantees the faithful duplication of the genome once per cell cycle, and any condition that compromises it is referred to as replication stress.

Depression changes people down to their DNA, a new study suggests. People with depression have more mitochondrial DNA and shorter telomeres than nondepressed people do, an international team of ...

Scientists revealed that ATAD5 actively deals with replication stress, in addition to its known function to prevent such stressful situations. Though ATAD5 has been known as a tumor suppressor by ...
