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 ...

Microsatellite unstable colorectal cancers are associated with increased CD1a- and CD83-positive dendritic cell infiltration

Biotechnology & Biotechnological Equipment, 2023
Microsatellite instability (MSI) is characterized by a highly immunogenic tumor phenotype and abundant lymphocytic infiltrates. The aim of this study was to investigate the association between four immunohistochemically determined classes of dendritic ...

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

Chromosomal instability in untreated primary prostate cancer as an indicator of metastatic potential. [PDF]

, 2020
BackgroundMetastatic prostate cancer (PC) is highly lethal. The ability to identify primary tumors capable of dissemination is an unmet need in the quest to understand lethal biology and improve patient outcomes.

Microsatellite instability (MSI, EMAST) in the pathogenesis of follicular lymphoma

Онкогематология, 2021
Background. Genetic instability, an important phenomenon involved in oncogenic transformation and tumor progression, is associated with the insufficiency of the multicomponent DNA repair complex, in particular, the nucleotide mismatch repair (MMR) system.

Prevalence of established and emerging biomarkers of immune checkpoint inhibitor response in advanced hepatocellular carcinoma. [PDF]

, 2019
The clinical deployment of immune checkpoint inhibitors (ICIs) has created a tandem drive for the identification of biomarkers linked to benefit. Comprehensive genomic profiling was performed to evaluate the frequency of genomic biomarkers of ICI ...
