To repair DNA damage, plants need good contractors

When a building is damaged, a general contractor often oversees various subcontractors—framers, electricians, plumbers and drywall hangers—to ensure repairs are done in the correct order and on time.

Biologists discover source for boosting tumor cell drug sensitivity

DNA-damaging agents, or "DDAs," make up the most widely used group of cancer drugs. Yet their therapeutic success has been curtailed by drug resistance—either present in cancer cells from the disease onset or arising during ...

Structural insights into processes at DNA damage sites

Ishan Deshpande and his colleagues from the group of Susan Gasser and the Protein Structure Facility at the FMI elucidated the mechanism of how Mec1-Ddc2, a tumor suppressor involved in DNA damage response assembles at sites ...

Histone degradation accompanies the DNA repair response

Earlier work from the laboratory of Susan Gasser had noted changes in the physical behavior of chromatin when it incurred DNA damage: loci bearing double-strand breaks showed enhanced movement, becoming highly dynamic. Furthermore, ...

Researchers discover new mechanism of DNA repair

The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed.

Researchers clarify how DNA damage signaling works

The DNA molecule is chemically unstable, giving rise to DNA lesions of various kinds. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed. The DNA damage response ...

Ancient protein-making enzyme moonlights as DNA protector

Scientists at The Scripps Research Institute (TSRI) have found that an enzyme best known for its fundamental role in building proteins has a second major function: to protect DNA during times of cellular stress.
