DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among ...

When cell division (mitosis) takes too long, it can be a sign that something is wrong with the cells, for example, DNA damage ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in ...

A noninvasive blood test to detect genetic material shed by tumors may help clinicians identify adverse events related to treatment with immune checkpoint inhibitor drugs, investigators at the Johns ...

When cell division (mitosis) takes too long, it can be a sign that something is wrong with the cells, for example DNA damage or chromosomal instability.

The researchers noted that “multiple clinical reports showed the repigmentation of grey hair within the darkening scalp areas ...

TY1 enhances the action of TREX1, a gene that helps immune cells clear damaged DNA, helping to minimize scar tissue post heart attacks.

Cells stop dividing when telomeres become too short to protect chromosomes, a process known as replicative senescence. But ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune defenses primed. Now researchers have identified a previously unknown form of ...

A virus carried by 95% of adults from childhood may trigger bladder cancer decades later by damaging cells during immune ...
