Synthesis and Quantitative Structure–Activity Relationship of Imidazotetrazine Prodrugs with Activity Independent of O6-Methylguanine-DNA-methyltransferase, DNA Mismatch Repair and p53. [PDF]

open access: yes, 2013
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

Intensive surveillance endoscopy for multiple gastrointestinal tumors in a patient with constitutional mismatch repair deficiency: case report

open access: yesBMC Gastroenterology, 2021
Background Constitutional mismatch repair deficiency (CMMRD) is an extremely rare autosomal recessive hereditary disease characterized by the absence of mismatch repair gene activity from birth, which results in brain tumors, colonic polyposis ...

Association of clinicopathological features with DNA mismatch repair status among colorectal cancer patients presenting to a Tertiary Care Cancer Hospital

open access: yesInternational Journal of Advanced Medical and Health Research, 2022
Background: About 12%–15% of sporadic colorectal cancers (CRCs) display a defect in the DNA mismatch repair (MMR) system resulting in microsatellite instability (MSI).

Selective Cytotoxicity of Rhodium Metalloinsertors in Mismatch Repair-Deficient Cells [PDF]

open access: yes, 2011
Mismatches in DNA occur naturally during replication and as a result of endogenous DNA damaging agents, but the mismatch repair (MMR) pathway acts to correct mismatches before subsequent rounds of replication.

The Eukaryotic Mismatch Recognition Complexes Track with the Replisome during DNA Synthesis.

open access: yesPLoS Genetics, 2015
During replication, mismatch repair proteins recognize and repair mispaired bases that escape the proofreading activity of DNA polymerase. In this work, we tested the model that the eukaryotic mismatch recognition complex tracks with the advancing ...

Mismatch Repair Deficiency and Microsatellite Instability

open access: yesEncyclopedia, 2022
Mismatch repair deficiency (MMRd) is caused by the biallelic inactivation of an MMR gene, which can be attributed either to an inherited or an acquired pathway.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

A rapid, simple DNA mismatch repair substrate construction method

open access: yesFrontiers in Oncology, 2011
A more flexible and higher yielding in vitro DNA mismatch repair (MMR) substrate construction method, which was developed initially by Wang and Hays, is described for the construction of a nucleotide-based chemical mismatch (G/IU) and a G/T mismatch. Our
