Endonuclease activities of MutLα and its homologs in DNA mismatch repair. [PDF]
MutLα is a key component of the DNA mismatch repair system in eukaryotes. The DNA mismatch repair system has several genetic stabilization functions. Of these functions, DNA mismatch repair is the major one.

DNA mismatch repair promotes APOBEC3-mediated diffuse hypermutation in human cancers
Certain mutagens, including the APOBEC3 (A3) cytosine deaminase enzymes, can create multiple genetic changes in a single event. Activity of A3s results in striking ‘mutation showers’ occurring near DNA breakpoints; however, less is known about the ...

Expression of the DNA mismatch repair proteins hMLH1 and hPMS2 in normal human tissues. [PDF]
hMLH1 and hPMS2 are part of the DNA mismatch repair complex. Mutations in these genes have been linked to hereditary non-polyposis colon cancer; they also occur in a variety of sporadic cancers. Western blot analysis and immunohistochemistry demonstrated

Conditional DNA repair mutants enable highly precise genome engineering [PDF]
Oligonucleotide-mediated multiplex genome engineering is an important tool for bacterial genome editing. The efficient application of this technique requires the inactivation of the endogenous methyl-directed mismatch repair system that in turn leads to ...

Sensing and Processing of DNA Interstrand Crosslinks by the Mismatch Repair Pathway
Summary: DNA interstrand crosslinks (ICLs) that are repaired in non-dividing cells must be recognized independently of replication-associated DNA unwinding. Using cell-free extracts from Xenopus eggs that support neither replication nor transcription, we

DNA repair systems and the pathogenesis of Mycobacterium tuberculosis: varying activities at different stages of infection [PDF]
Mycobacteria, including most of all MTB (Mycobacterium tuberculosis), cause pathogenic infections in humans and, during the infectious process, are exposed to a range of environmental insults, including the host's immune response.

Synthesis and Quantitative Structure–Activity Relationship of Imidazotetrazine Prodrugs with Activity Independent of O6-Methylguanine-DNA-methyltransferase, DNA Mismatch Repair and p53. [PDF]
The antitumor prodrug Temozolomide is compromised by its dependence for activity on DNA mismatch repair (MMR) and the repair of the chemosensitive DNA lesion, O6-methylguanine (O6-MeG), by O6-methylguanine-DNA-methyltransferase (EC 2.1.1.63, MGMT). Tumor

Escherichia coli frameshift mutation rate depends on the chromosomal context but not on the GATC content near the mutation site. [PDF]
Different studies have suggested that mutation rate varies at different positions in the genome. In this work we analyzed if the chromosomal context and/or the presence of GATC sites can affect the frameshift mutation rate in the Escherichia coli genome.

DNA repair mechanisms and gametogenesis [PDF]
In mammals, there is a complex and intriguing relationship between DNA repair and gametogenesis. DNA repair mechanisms are involved not only in the repair of different types of DNA damage in developing germline cells, but ...
