To avoid genome instability, DNA repair nucleases must precisely target the correct damaged substrate before they are licensed to incise. Damage identification is a challenge for all DNA damage response proteins, but especially for nucleases that cut the DNA and necessarily create a cleaved DNA repa
Abstract One major pathological hallmark of Alzheimer's disease (AD) is accumulation of senile plaques in patients' brains, mainly composed of amyloid beta-peptide (Aβ). Nicotinamide adenine dinucleotide (NAD) has emerged as a common mediator regulating energy metabolism, mitochondrial function, ag

The present study aimed to examine the effects of recombinant human growth hormone (rhGH) on the sensitivity of a colorectal cancer cell line to radiotherapy, and to investigate its association with DNA damage and repair. Flow cytometry and immunofluorescence were employed to detect growth hormone r

… On the other hand, 12 and 24 hr exposure to PFOA (100 µM) increased DNA migration in electrophoresis condition at pH 13, but not at pH 12.1, suggesting that the DNA damage may be alkali labile site (such as apurinic/apyrimidinic (AP) site). …
In biochemistry and molecular genetics, an AP site (apurinic/apyrimidinic site), also known as an abasic site, is a location in DNA ... It has been estimated that under physiological condition 10,000 apurinic sites may be generated in a cell daily.
