Estimating the Rate of Mutation to a Mutator Phenotype
A mutator is a variant in a population of organisms whose mutation rate is higher than the average mutation rate in the population. For genetic and population dynamics reasons, mutators are produced and survive with much greater frequency than anti ...

Detection of mutator phenotype in Brazilian patients with acute and chronic myeloid leukemia
The multisteps of tumorigenesis involve the classic chromosomal instability and the mutator phenotype pathways featured by a predisposition to acquire mutations in tumor suppressor genes and oncogenes.

Estimating the mutation rate to mutator phenotypes
The mutator phenotype hypothesis by Loeb et al. (1974) proposes the existence of cells that have a higher mutation rate than the rest of the cell population and that, consequently, occasionally favor the appearance of mutant cells. Such cells, often called mutator cells, are related to drug resistance, genetic instability, and increasing the ...

The TK6 lymphoblastoid cell line is known to be mismatch repair (MMR) and p53 proficient. Deficiency in MMR results in a mutator phenotype characterized by microsatellite instability (MSI) and increased hprt mutant frequency (MF).

XPC deficiency increases risk of hematologic malignancies through mutator phenotype and characteristic mutational signature [PDF]
Xeroderma Pigmentosum group C (XP-C) is a rare genetic disorder characterised by deficient DNA repair leading to skin and internal cancer, but the latter is not well understood molecularly.

A transient mutational burst occurs during yeast colony development [PDF]
Characterizing the contribution of mutators to mutation accumulation is essential for understanding cellular adaptation and diseases like cancer. By measuring single and double mutation rates, including point mutations, segmental duplications, and ...

A Mutator Phenotype Promoting the Emergence of Spontaneous Oxidative Stress-Resistant Mutants in Campylobacter jejuni. [PDF]
Campylobacter jejuni is a leading cause of foodborne illnesses worldwide. As a microaerophilic organism, C. jejuni must be able to defend against oxidative stress encountered both in the host and in the environment ...
