High prevalence of NTRK fusions in sporadic dMMR/MSI mCRC RAS/RAF wild-type: an opportunity for a post-immune checkpoint inhibitors progression rescue strategy

ESMO Gastrointestinal Oncology
Background: Currently, mismatch repair deficient/microsatellite instable (dMMR/MSI) status constitutes a validated predictive marker of response to immune checkpoint inhibitors (ICIs) in patients with metastatic colorectal cancer (mCRC).

A molecular portrait of microsatellite instability across multiple cancers

Nature Communications, 2017
Some cancers with DNA mismatch repair deficiency display microsatellite instability. Here the authors analyse twenty three cancer types at the exome and whole-genome level, and identify loci with recurrent microsatellite instability that could be used to

Mismatch Repair Deficiency and Microsatellite Instability

Encyclopedia, 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.

Fusobacterium nucleatum infection correlates with two types of microsatellite alterations in colorectal cancer and triggers DNA damage

Gut Pathogens, 2020
Fusobacterium nucleatum (Fn) is frequently found in colorectal cancers (CRCs). High loads of Fn DNA are detected in CRC tissues with microsatellite instability-high (MSI-H), or with the CpG island hypermethylation phenotype (CIMP).

Mitochondrial DNA alteration in primary and metastatic colorectal cancer: Different frequency and association with selected clinicopathological and molecular markers

Tumor Biology, 2017
This study attempts to determine whether primary tumor tissue could reliably represent metastatic colorectal cancer in therapy-guiding analysis of mitochondrial microsatellite instability.

High incidence of microsatellite instability and loss of heterozygosity in three loci in breast cancer patients receiving chemotherapy: a prospective study

BMC Cancer, 2012
Background The aim of the study was to evaluate potential chemotherapy-induced microsatellite instability, loss of heterozygosity, loss of expression in mismatch repair proteins and associations with clinical findings in breast cancer patients ...

Clinicoprognostical features of endometrial cancer patients with somatic mtDNA mutations [PDF]

, 2014
Somatic mitochondrial DNA (mtDNA) mutations have been found in a subset of endometrial cancers (EC) from different populations. We have investigated the relationship between mtDNA changes and clinical and pathological variables of women affected by ...

Squamous Cell Carcinoma of the Lung With Microsatellite Instability in a Patient With Lynch Syndrome: A Case Report

JTO Clinical and Research Reports
Lynch syndrome is the most common autosomal dominant inherited cancer predisposing syndrome, due to mutations in DNA mismatch repair genes. The key feature of cancers in Lynch syndrome is microsatellite instability and a high risk of developing mainly ...

Instability of a dinucleotide repeat in the 3′‐untranslated region (UTR) of the microsomal prostaglandin E synthase‐1 (mPGES‐1) gene in microsatellite instability‐high (MSI‐H) colorectal carcinoma

Molecular Oncology, 2015
DNA mismatch‐repair gene mutations, with consequent loss of functional protein expression, result in microsatellite instability (MSI). Microsatellite sequences are found in coding regions and in regulatory regions of genes (i.e., 5′‐UTRs and 3′‐UTRs). In

Signalling cell cycle arrest and cell death through the MMR System [PDF]

, 2006
Loss of DNA mismatch repair (MMR) in mammalian cells, as well as having a causative role in cancer, has been linked to resistance to certain DNA damaging agents including clinically important cytotoxic chemotherapeutics.
