The evolutionary drive to maintain neurons that we see in jellyfish and sea anemones is perhaps one of the reasons why sleep is essential for humans today, Appelbaum said.

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

Organisms like eukaryotes and prokaryotes have sophisticated mechanisms of DNA repair after damage. Failure of repairing the DNA damage is considered to be the cause of induction of cell death, ...

Researchers at The Institute of Cancer Research, London identified the CIP2A–TOPBP1 complex as a master regulator of DNA repair during mitosis, coordinating backup pathways that protect chromosomes ...

Researchers have discovered how a metabolite involved in repairing damaged DNA not only controls a person’s sensitivity to cancer therapies but can also protect healthy tissues from damage. The ...

New research led by researchers at the University of California, San Diego (UCSD), School of Medicine, reveals a novel map that depicts the human body’s system for addressing and repairing DNA ...

Researchers have uncovered a novel mechanism for repairing DNA damage in neurons The study reveals a protein complex that initiates a pathway to repair DNA breaks induced by neuronal activity “More ...

DNA can be damaged by normal cellular processes as well as external factors such as UV radiation and chemicals. Such damage can lead to breaks in the DNA strand. If DNA damage is not properly repaired ...
