KRAS Mutational Regression Is Associated With Oligo-Metastatic Status and Good Prognosis in Metastatic Colorectal Cancer

open access: yesFrontiers in Oncology, 2021
BackgroundWe previously reported that loss of KRAS mutations (“regressive” mutational trajectories) from primary tumors to metastases associated with the oligo-metastatic status in colorectal cancer (CRC).

Nucleic acid mutation analysis using catalytic DNA

open access: yesNucleic Acids Research, 2000
The sequence specificity of the '10-23' RNA-cleaving DNA enzyme (deoxyribozyme) was utilised to discriminate between subtle differences in nucleic acid sequence in a relatively conserved segment of the L1 gene from a number of different human papilloma virus (HPV) genotypes.

Ancient DNA Analysis of the Delta F508 Mutation

open access: yesHuman Biology, 2003
When working with highly degraded DNA, validating the results of a slightly polymorphic system always complicates the analysis because of the difficulties in recognizing contamination and artifacts. Recognition can be greatly simplified by employing a multiplex reaction that coamplifies the fragments together with several highly polymorphic markers ...

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

open access: yesACS 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.

Annotation of Genes Having Candidate Somatic Mutations in Acute Myeloid Leukemia with Whole-Exome Sequencing Using Concept Lattice Analysis [PDF]

open access: yesGenomics & Informatics, 2013
In cancer genome studies, the annotation of newly detected oncogene/tumor suppressor gene candidates is a challenging process. We propose using concept lattice analysis for the annotation and interpretation of genes having candidate somatic mutations in ...

Mutational analysis of conserved residues in HhaI DNA methyltransferase [PDF]

open access: yesNucleic Acids Research, 2002
HhaI DNA methyltransferase belongs to the C5-cytosine methyltransferase family, which is characterized by the presence of a set of highly conserved amino acids and motifs present in an invariant order. HhaI DNA methyltransferase has been subjected to a lot of biochemical and crystallographic studies.

The Landscape of Actionable Genomic Alterations by Next-Generation Sequencing in Tumor Tissue Versus Circulating Tumor DNA in Chinese Patients With Non-Small Cell Lung Cancer

open access: yesFrontiers in Oncology, 2022
BackgroundCirculating tumor DNA (ctDNA) sequence analysis shows great potential in the management of non-small cell lung cancer (NSCLC) and the prediction of drug sensitivity or resistance in many cancers.

Mutational signatures of redox stress in yeast single-strand DNA and of aging in human mitochondrial DNA share a common feature.

open access: yesPLoS Biology, 2019
Redox stress is a major hallmark of cancer. Analysis of thousands of sequenced cancer exomes and whole genomes revealed distinct mutational signatures that can be attributed to specific sources of DNA lesions.

Accuracy of mutational signature software on correlated signatures

open access: yesScientific Reports, 2022
Mutational signatures are characteristic patterns of mutations generated by exogenous mutagens or by endogenous mutational processes. Mutational signatures are important for research into DNA damage and repair, aging, cancer biology, genetic toxicology ...
