A research team has unveiled a crucial mechanism that helps regulate DNA damage repair, with important implications for improving cancer treatment outcomes. The result was published in Cell Death & ...

DNA mismatch repair (MMR) is a fundamental pathway that maintains genomic integrity by recognising and correcting errors introduced during DNA replication and recombination. In prokaryotes, the ...

Eukaryotic DNA replication is initiated at multiple origins through a tightly regulated sequence of events: origin licensing, helicase activation and assembly of the replisome. The replicative ...

Huntington's disease is a genetic disorder that kills nerve cells in the brain, causing people to lose their cognitive and motor abilities. New research led by Thomas Jefferson University researcher ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal metabolic processes or external stressors such as radiation or chemical ...

Scientists have captured the most detailed structural images to date of a specific type of protein's DNA repair process, a finding that could reveal ways to inhibit the effects of BRCA1 and BRCA2 ...

In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At ...

A new review finds that next-generation BET-targeted therapies, including selective inhibitors and PROTACs, are addressing ...

Three biochemical steps of the non-homologous DNA end-joining (NHEJ) process. This figure outlines the key stages of the NHEJ repair mechanism following DNA double-strand breaks. The process can be ...

Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...

The bowhead whale’s remarkable lifespan and low cancer risk stem from a finely tuned DNA repair system driven by a unique protein, CIRBP. Scientists found that this mechanism not only preserves the ...

DNA Damage Response (“DDR”) inhibitors, a category of drugs that work by blocking cancer cells' capacity to fix their own damaged DNA, are growing well beyond the poly ADP ribose polymerase (“PARP”) ...
