Numerous processes are likely to affect low-dose radiation cancer risk. Here, the types of DNA damage induced at low doses, the DNA damage response (DDR; a network of pathways that protect against ...

Radiation inflicts extensive damage on cells’ DNA. For many cells, the damage is too complex to repair, and the cells die–making radiotherapy a frontline cancer treatment. However, some tumor cells ...

cells become more sensitive to DNA damaging agents. Researchers in the 1960s isolated the first radiation-sensitive mutants in yeast. By the 1970s, researchers had identified a great number of ...

That radiation was potentially strong enough to break apart DNA. "But we're not biologists," laughed Nojiri. Thus, the team ...

Mouse cells tweaked to produce the tardigrade protein incurred less DNA damage than unaltered cells — hinting at a new tool for cancer patient care.

Research shows UV radiation modifies 3D genome structure, affecting DNA damage response and gene activity, offering insights ...

They can also tolerate high doses of radiation. Researchers previously discovered that tardigrades can survive more than 1,000 times the lethal dose for humans. 1 So, how do these tiny creatures ...

DNA damage response: More than just repair In addition to fixing damaged DNA, the researchers discovered that UV radiation triggers changes in gene activity.Some genes, particularly those involved ...
