Therefore, a decline in DNA-PK subunit levels and its kinase activity may, for the time being, serve as biomarkers until future studies, especially in vivo studies, add to substantiate a direct link of DNA-PK to AD.
The linking of DNA markers to specific traits -- such as an undesirable grassy aroma or a highly desirable disease resistance -- will make breeding for complex traits more efficient.
My discovery of the photochemical cross-linking of DNA and proteins in bacteria was reported in 1962 (A13), and its biological importance (A17, A21) and its chemical basis (A18, A24, A31, A37) were established in a series of papers.
Linking of DNA vouchers with global positioning system data and herbarium vouchers and other data about the site of collection is desirable to add scientific value to collections.
In brief, cell extracts were prepared after in vivo cross-linking of DNA and proteins with formaldehyde, and incubated with agarose beads conjugated with anti-FLAG antibody (Sigma) to precipitate Yku70-3FLAG or Pre6-3FLAG and bound DNA fragments.
Intra- and interstrand cross-linking of DNA by cisplatin block DNA replication and gene transcription.
Following washes and elution, precipitates were heated overnight at 65°C to reverse cross-linking of DNA and protein.
Bendamustine induces DNA damage through intra- and inter-strand cross-linking of DNA base pairs, which subsequently leads to cell apoptosis.
Ku-dependent linking of DNA molecules has also been shown to be promoted in vitro by DNA ligase IV/XRCC4, which is known to stabilize Ku's association with DNA ends (Zhang et al., 2007).
Cr III -mediated Cr III -mediatedNA with peptide glutathione or single amino acids were mutagenic in human cells, with a relatiofship of higher molecular weight of the peptiDNAamino acid correlating with a more peptidemutaglutathionense.
