Does sex of the patient play a role in survival for MSI colorectal cancer? [PDF]

open access: yes, 2018
Microsatellite instability (MSI) is a feature of colorectal tumors that develops as a result of inactivation of the DNA mismatch repair system. It is found in about 15% of all colorectal cancers and is an important prognostic molecular marker when ...

Aberrant methylation within RUNX3 CpG island associated with the nuclear and mitochondrial microsatellite instability in sporadic gastric cancers. Results of a GOIM (Gruppo Oncologico dell'Italia Meridionale) prospective study. [PDF]

open access: yes, 2007
Gastric cancer (GC) development is a multistep process, during which numerous alterations accumulate in nuclear and mitochondrial DNA. A deficiency of repair machinery brings about an accumulation of errors introduced within simple repetitive ...

Microsatellite Instability in Yeast: Dependence on the Length of the Microsatellite [PDF]

open access: yesGenetics, 1997
One of the most common microsatellites in eukaryotes consists of tandem arrays [usually 15-50 base pairs (bp) in length] of the dinucleotide GT. We examined the rates of instability for poly GT tracts of 15, 33, 51, 99 and 105 bp in wild-type and mismatch repair-deficient strains of Saccharomyces cerevisiae. Rates of instability increased more than two

Profiling diverse sequence tandem repeats in colorectal cancer reveals co-occurrence of microsatellite and chromosomal instability involving Chromosome 8

open access: yesGenome Medicine, 2021
We developed a sensitive sequencing approach that simultaneously profiles microsatellite instability, chromosomal instability, and subclonal structure in cancer. We assessed diverse repeat motifs across 225 microsatellites on colorectal carcinomas.

Relationship between protein biomarkers of chemotherapy response and microsatellite status, tumor mutational burden and PD-L1 expression in cancer patients. [PDF]

open access: yes, 2020
Chemotherapy and checkpoint inhibitor immunotherapies are increasingly used in combinations. We determined associations between the presence of anti-PD-1/PD-L1 therapeutic biomarkers and protein markers of potential chemotherapy response.

Microsatellite Instability in Malignant Melanoma [PDF]

open access: yesCancer Genetics and Cytogenetics, 1998
Defective mismatch repair has been detected in human colorectal and endometrial carcinomas which exhibit microsatellite instability (MIN). The purpose of this study was to search for MIN in melanoma. Paraffin-embedded neoplastic and non-neoplastic control cells were obtained from 20 untreated individuals with cutaneous malignant melanoma.

Phase Ib study of anlotinib combined with TQB2450 in pretreated advanced biliary tract cancer and biomarker analysis

open access: yesHepatology, EarlyView., 2022
Phase 1b study of anlotinib combined with TQB2450 in pretreated advanced biliary tract cancer and biomarker analysis. Abstract Background and Aims We evaluated the efficacy and safety of the antiangiogenic tyrosine kinase inhibitor anlotinib plus TQB2450, a programmed death‐ligand 1 inhibitor in pretreated advanced biliary tract cancers (BTCs ...

Medullary colonic carcinoma with microsatellite instability has lower survival compared with conventional colonic adenocarcinoma with microsatellite instability

open access: yesGastroenterology Review, 2016
Introduction: Colorectal medullary carcinoma (MC) is a rare subtype of poorly differentiated adenocarcinoma (PDA) with unclear prognostic significance.

Association between c-type lectin-like receptor 2 and microsatellite instability in colorectal cancer: a cross-sectional study

open access: yesBMC Cancer, 2022
Background As a transmembrane protein, C-type lectin-like receptor 2 (CLEC-2) is mainly expressed on platelets and released into plasma after platelet activation. Activated platelets participate in the regulation of innate immune cells.

Extended microsatellite analysis in microsatellite stable, MSH2 and MLH1 mutation-negative HNPCC patients: Genetic reclassification and correlation with clinical features [PDF]

open access: yes, 2004
Background: Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant disorder predisposing to predominantly colorectal cancer (CRC) and endometrial cancer frequently due to germline mutations in DNA mismatch repair (MMR) genes, mainly ...
