Single-nucleotide polymorphism profiling by multimodal-targeted next-generation sequencing in methotrexate-resistant and -sensitive human osteosarcoma cell lines

Frontiers in Pharmacology, 2023
Introduction: Methotrexate (MTX) is one of the most important drugs included in the first-line protocols to treat high-grade osteosarcoma (HGOS). Although several polymorphisms have been reported to be associated with drug response or MTX-related ...

Combined MLH1/MSH2/MSH6 assessment by IHC and RT-qPCR: Differential expression analysis and incremental value for pathological risk stratification in colorectal cancer [PDF]

Journal of Medical Biochemistry
Background: Mismatch repair (MMR) status is routinely assessed in colorectal cancer (CRC), yet the laboratory value of combining multiple MMR targets across platforms for risk stratification requires verification under real-world testing conditions. This

Monosodium glutamate-induced alterations in MMR protein expression: A potential mechanism linking diet and colorectal cancer

Gastroenterology & Endoscopy
Background: Defective mismatch repair (MMR) proteins activate the microsatellite instability (MSI) pathway, contributing to colon carcinogenesis. Monosodium glutamate (MSG), a widely used flavor enhancer, has been implicated in colorectal cancer (CRC ...

Accuracy of four mononucleotide-repeat markers for the identification of DNA mismatch-repair deficiency in solid tumors

Journal of Translational Medicine, 2018
Background To screen tumors with microsatellite instability (MSI) arising due to DNA mismatch repair deficiency (dMMR), a panel of five quasi-monomorphic mononucleotide-repeat markers amplified in a multiplex PCR (Pentaplex) are commonly used.
