DNArCdb: A database of cancer biomarkers in DNA repair genes that includes variants related to multiple cancer phenotypes.

Functioning DNA repair capabilities are vital for organisms to ensure that the biological information is preserved and correctly propagated. Disruptions in DNA repair pathways can result in the accumulation of DNA mutations, which may lead to onset of complex disease such as cancer. The discovery and characterization of cancer-related biomarkers may allow early diagnosis and targeted treatment, which could significantly contribute to the survival rates of cancer patients.

Insights into conformational changes in AlkD bound to DNA with a yatakemycin adduct from computational simulations.

Structural integrity of DNA molecules is necessary for their information storage function. Cells rely on a number of pathways to ensure that the damage to DNA induced by endogenous and exogenous reagents is repaired. AlkD, a base excision enzyme, removes a damaged nucleobase by cleaving a glycosidic bond.

ALKBH7 Variant Related to Prostate Cancer Exhibits Altered Substrate Binding.

The search for prostate cancer biomarkers has received increased attention and several DNA repair related enzymes have been linked to this dysfunction. Here we report a targeted search for single nucleotide polymorphisms (SNPs) and functional impact characterization of human ALKBH family dioxygenases related to prostate cancer. Our results uncovered a SNP of ALKBH7, rs7540, which is associated with prostate cancer disease in a statistically significantly manner in two separate cohorts, and maintained in African American men.

Homology modeling, molecular dynamics, and site-directed mutagenesis study of AlkB human homolog 1 (ALKBH1).

The ability to repair DNA is important for the conservation of genetic information of living organisms. Cells have a number of ways to restore damaged DNA, such as direct DNA repair, base excision repair, and nucleotide excision repair. One of the proteins that can perform direct repair of DNA bases is Escherichia coli AlkB.
