A novel approach for characterizing microsatellite instability in cancer cells. [PDF]

PLoS ONE, 2013
Microsatellite instability (MSI) is characterized by the expansion or contraction of DNA repeat tracts as a consequence of DNA mismatch repair deficiency (MMRD).

DNA mismatch repair-related protein loss as a prognostic factor in endometrial cancers

Journal of Gynecologic Oncology, 2015
Objective Recent investigations have revealed DNA mismatch repair (MMR) gene mutations are closely related with carcinogenesis of endometrial cancer; however the impact of MMR protein expression on prognosis is not determined.

Integrated Metallo‐Dielectric 3D Hotspots From High Refractive Index Nanodiamond‐Plasmonic Gold Cryosoret Nano‐Assemblies for Photonic Crystal Enhanced Fluorescence

Advanced Functional Materials, EarlyView.
This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Znaczenie mechanizmu naprawy DNA błędnie sparowanych zasad azotowych (MMR) w raku piersi

Menopause Review, 2010
Background: Microsatellite instability (MSI) is due to defective DNA mismatch repair. Defects in DNA mismatch-repair (MMR) genes lead to replication errors revealed as instability in microsatellite markers.

DNA mismatch repair in the context of chromatin

Cell & Bioscience, 2020
DNA mismatch repair (MMR) maintains replication fidelity by correcting mispaired nucleotides incorporated by DNA polymerases. Defects in MMR lead to cancers characterized by microsatellite instability.

ApoE gene therapy: an overview and update [PDF]

, 2005
Atherosclerosis remains the leading cause of death in industrialized societies. Apolipoprotein E (ApoE) is an attractive candidate to treat hypercholesterolemia and coronary heart disease, as it is a circulating protein with pleiotropic ...

The Importance of DNA Repair in Tumor Suppression

, 2004
The transition from a normal to cancerous cell requires a number of highly specific mutations that affect cell cycle regulation, apoptosis, differentiation, and many other cell functions.

Wafer‐Scale Integration of α‐quartz Thin Films toward Super High Frequency Piezoelectric bioNEMS for Chikungunya Virus Detection

Advanced Functional Materials, EarlyView.
Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

Absence of MutSβ leads to the formation of slipped-DNA for CTG/CAG contractions at primate replication forks [PDF]

, 2016
Typically disease-causing CAG/CTG repeats expand, but rare affected families can display high levels of contraction of the expanded repeat amongst offspring.
