Abstract Acute kidney injury (AKI) is a common perioperative complication that is associated with increased mortality. This study investigates the renal gene expression in male Long–Evans rats after prolonged anesthesia and surgery to detect molecu

In model DNA, A pairs with T, and C with G. However, in vivo, the complementarity of the DNA strands may be disrupted by errors in DNA replication, biochemical modification of bases and recombination. In prokaryotic organisms, mispaired bases are rec

5-Azacytidine induces CG-to-GC transversion mutations in Escherichia coli. The results presented in this paper provide evidence that repair of the drug-induced lesions that produce these mutations involves components of both the mismatch repair and n

Trp-999 is a key residue for the action of beta-galactosidases (Escherichia coli). Several site specific substitutions (Phe, Gly, Tyr, Leu) for Trp-999 were made. Each substitution caused greatly decreased affinities for substrates and inhibitors tha

Vsr mediates very short patch repair in Escherichia coli, correcting T/G mismatches caused by deamination of 5-methylcytosine to thymine. MutS and MutL, part of the post-replication mismatch repair system, stimulate VSP repair. In this study, we use

We have developed and tested a simple phenotypic assay which monitors C to T transition mutations at the second C of a CCAGG sequence in the lacZ gene of Escherichia coli . The assay is based on new data concerning amino acid requirements on either s

Base pair mismatches in DNA arise from errors in DNA replication, recombination, and biochemical modification of bases. Mismatches are inherently transient. They are resolved passively by DNA replication, or actively by enzymatic removal and resynthe

DNA mismatch repair (MMR) and very-short patch (VSP) repair are two pathways involved in the repair of T:G mismatches. To learn about competition and cooperation between these two repair pathways, we analyzed the physical and functional interaction b

The activities of the Vsr and MutH endonucleases of Escherichia coli are stimulated by MutL. The interaction of MutL with each enzyme is enhanced in vivo by 2-aminopurine treatment and by inactivation of the mutY gene. We hypothesize that MutL recrui
