Alternatively, the DNA polymerase can insert multiple bases, leading to the displacement of a small oligonucleotide, which is subsequently removed by a flap endonuclease. Mismatch repair primarily ...

However, the mechanistic connections between mismatch DNA repair and selective neuronal vulnerability in Huntington's disease remained unknown. The new study from UCLA Health and Jane and Terry ...

But the method is complex and inefficient. A research group has now been able to show that the DNA mismatch repair process plays an essential role in prime editing. Prime editing is an improved ...

However, the mechanistic connections between mismatch DNA repair and selective neuronal vulnerability in Huntington’s disease remain unknown. The new study from UCLA Health and the Jane and ...

The process involves the recognition of damage which is then cleaved on both sides by endonucleases before resynthesis by DNA polymerase. The third excision mechanism is called mismatch repair and ...

The DNA mismatch repair (MMR) system is necessary for the maintenance of genomic stability. In a broad sense, all main functions of the MMR system, including the correction of biosynthetic errors, DNA ...

Their work details how cells repair damaged DNA and preserve genes ... finding that they use mismatch repair to sharply reduce the frequency of errors. In making these discoveries, the researchers ...

Pembrolizumab (Keytruda), an anti-PD-1 antibody, cleared minimal residual disease and protected against recurrence in patients with DNA mismatch repair-deficient (dMMR) early-stage solid cancers ...

Defects in the DNA mismatch repair machinery can be identified by detection of the loss of MMR protein expression with the use of immunohistochemical analysis or by detection of microsatellite ...
