Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and ...

Homologous recombination is a DNA repair mechanism that counteracts double-stranded breaks in DNA. Researchers at Kindai University have recently revealed how the Sae2 protein coordinates with the ...

Cancer cells survive by repairing damage to their DNA—even damage that would normally be fatal. One of their most important ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

Poly(ADP‐ribose) polymerases (PARPs) are a family of enzymes that play a crucial role in maintaining genomic integrity by detecting DNA damage and facilitating its repair. By catalysing the covalent ...

A research team has successfully identified a novel DNA damage repair pathway in human cells. This study is the first to discover that proteins present in the nuclear membrane of cells directly ...

From proofreading polymerases to complex backup repair systems, DNA repair is a high-yield MCAT topic that bridges molecular biology and human health. Understanding the mechanisms that safeguard ...

DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

Proteins PIF1 and PCNA gather at sites of DNA damage in SETX-deficient cells, indicating activation of the BIR repair system. LA JOLLA, CA—The DNA inside our cells is constantly being damaged, and one ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

Unlike cancer cells, which depend on Pol-theta as a workaround for defective repair pathways, healthy ones rely on more accurate repair mechanisms that require energy-ensuring more precise DNA repair.
