DNA Pooling in Mutation Detection with Reference to Sequence Analysis [PDF]

open access: bronzeThe American Journal of Human Genetics, 2000
We discuss pooling methods of mutation detection for identifying rare mutations. We provide mathematical formulae for obtaining the optimal pool size as a function of the mutation frequency in the study population and the specificity of the test. The optimal pool size depends strongly on the specificity of the test. With a test that has 99% specificity,

Label-Free Detection of DNA Mutations by Nanopore Analysis [PDF]

open access: greenACS Applied Materials & Interfaces, 2018
Cancers are caused by mutations to genes that regulate cell normal functions. The capability to rapid and reliable detection of specific target gene variations can facilitate early disease detection and diagnosis and also enables personalized treatment of cancer.

Survival analysis of DNA mutation motifs with penalized proportional hazards

open access: greenThe Annals of Applied Statistics, 2019
Antibodies, an essential part of our immune system, develop through an intricate process to bind a wide array of pathogens. This process involves randomly mutating DNA sequences encoding these antibodies to find variants with improved binding, though mutations are not distributed uniformly across sequence sites. Immunologists observe this nonuniformity

Divergent mutational processes distinguish hypoxic and normoxic tumours. [PDF]

open access: yes, 2020
Many primary tumours have low levels of molecular oxygen (hypoxia), and hypoxic tumours respond poorly to therapy. Pan-cancer molecular hallmarks of tumour hypoxia remain poorly understood, with limited comprehension of its associations with specific ...

Arrival of Paleo-Indians to the Southern Cone of South America: New Clues from Mitogenomes [PDF]

open access: yes, 2012
With analyses of entire mitogenomes, studies of Native American mitochondrial DNA (mtDNA) variation have entered the final phase of phylogenetic refinement: the dissection of the founding haplogroups into clades that arose in America during and after ...

Mutational analysis of mitochondrial DNA in Brugada syndrome [PDF]

open access: yesCardiovascular Pathology, 2016
Brugada syndrome (BrS) is a primary electrical disease associated with an increased risk of sudden cardiac death due to ventricular fibrillation. This pathology has nuclear heterogeneous genetic origins, and at present, molecular diagnostic tests on nuclear DNA cover only 30% of BrS patients. The aim of this study was to assess the possible involvement

Common Mitochondrial DNA Mutations Generated through DNA-Mediated Charge Transport [PDF]

open access: yes, 2009
Mutation sites that arise in human mitochondrial DNA as a result of oxidation by a rhodium photooxidant have been identified. HeLa cells were incubated with [Rh(phi)2bpy]Cl3 (phi is 9,10-phenanthrenequinone diimine), an intercalating photooxidant, to ...

Chitosan-modified graphene electrodes for DNA mutation analysis [PDF]

open access: yesJournal of Electroanalytical Chemistry, 2012
Graphene has remarkable electrochemical properties that make it an ideal material for constructing biosensors,however it has not been explored for DNA biosensing. Herein, we report on a chitosan-modified graphene platform for the electrochemical detection of changes in DNA sequences.

The C Terminus of Ku80 activates the DNA-dependent protein kinase catalytic subunit [PDF]

open access: yes, 1999
Ku is a heterodimeric protein with double-stranded DNA end-binding activity that operates in the process of nonhomologous end joining. Ku is thought to target the DNA-dependent protein kinase (DNA-PK) complex to the DNA and, when DNA bound, can interact ...

Quantitative Mitochondrial DNA Mutation Analysis by Denaturing HPLC [PDF]

open access: yesClinical Chemistry, 2007
AbstractBackground: In recent years, denaturing HPLC (DHPLC) has been widely used to screen the whole mitochondrial genome or specific regions of the genome for DNA mutations. The quantification and mathematical modeling of DHPLC results is, however, underexplored.Methods: We generated site-directed mutants containing some common mutations in the ...
