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

BMC 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.

Genetic changes of MLH1 and MSH2 genes could explain constant findings on microsatellite instability in intracranial meningioma

Tumor Biology, 2017
Postreplicative mismatch repair safeguards the stability of our genome. The defects in its functioning will give rise to microsatellite instability. In this study, 50 meningiomas were investigated for microsatellite instability. Two major mismatch repair

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

Genome 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.

Mismatch repair-deficient crypt foci in Lynch syndrome--molecular alterations and association with clinical parameters. [PDF]

PLoS ONE, 2015
Lynch syndrome is caused by germline mutations of DNA mismatch repair (MMR) genes, most frequently MLH1 and MSH2. Recently, MMR-deficient crypt foci (MMR-DCF) have been identified as a novel lesion which occurs at high frequency in the intestinal mucosa ...

European guidelines from the EHTG and ESCP for Lynch syndrome: an updated third edition of the Mallorca guidelines based on gene and gender

BJS (British Journal of Surgery), EarlyView., 2020
Recommendations for clinical and molecular identification of LS, surgical and endoscopic management of LS‐associated colorectal cancer and preventive measures for cancer were produced. The emphasis was on surgical and gastroenterological aspects of the cancer spectrum.

Mismatch repair deficiency/microsatellite instability-high as a predictor for anti-PD-1/PD-L1 immunotherapy efficacy

Journal of Hematology & Oncology, 2019
Immunotherapies have led to substantial changes in cancer treatment and have been a persistently popular topic in cancer research because they tremendously improve the efficacy of treatment and survival of individuals with various cancer types.

Durable response to pembrolizumab in microsatellite instability‐high advanced adrenocortical carcinoma

IJU Case Reports, 2023
Introduction Advanced adrenocortical carcinoma has a poor prognosis and is treated with chemotherapy that includes mitotane with etoposide, doxorubicin, and cisplatin as first‐line therapy.

Relationship of microsatellite instability to mismatch repair deficiency in malignant tumors of dogs

Journal of Veterinary Internal Medicine, 2022
Background Microsatellite instability (MSI) is a type of genomic instability caused by mismatch repair deficiency (dMMR) in tumors. Studies on dMMR/MSI are limited, and the relationship between dMMR and MSI is unknown in tumors of dogs.

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
