The Role of Cytosine Methylation on Charge Transport through a DNA Strand [PDF]

open access: yesJ Chem Phys. 2015 Sep 7;143(9):094306, 2017
Cytosine methylation has been found to play a crucial role in various biological processes, including a number of human diseases. The detection of this small modification remains challenging. In this work, we computationally explore the possibility of detecting methylated DNA strands through direct electrical conductance measurements.

Intragenic DNA methylation: implications of this epigenetic mechanism for cancer research [PDF]

open access: yes, 2011
Epigenetics is the study of all mechanisms that regulate gene transcription and genome stability that are maintained throughout the cell division, but do not include the DNA sequence itself.

Unlocking the potential of tumor‐derived DNA in urine for cancer detection: methodological challenges and opportunities

open access: yesMolecular Oncology, EarlyView.
Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...

Hypermethylation of the TPEF/HPP1 Gene in Primary, Metastatic Colorectal Cancers

open access: yesNeoplasia: An International Journal for Oncology Research, 2005
The role of promoter methylation in the process of cancer cell metastasis has not yet been studied. Recently, methylation of the TPEF (transmembrane protein containing epidermal growth factor, follistatin domain) gene was reported in human colon, gastric,

UV photodissociation of methyl bromide and methyl bromide cation studied by velocity map imaging [PDF]

open access: yesJournal of Chemical Physics 130 (2009) 034304, 2009
We employ the velocity map imaging technique to measure kinetic energy and angular distributions of state selected CH3 (v2=0,1,2,3) and Br (2P3/2,2P1/2) photofragments produced by methyl bromide photolysis at 215.9 nm. These results show unambiguously that the Br and Br* forming channels result in different vibrational excitation of the umbrella mode ...

Clinical applications of next‐generation sequencing‐based ctDNA analyses in breast cancer: defining treatment targets and dynamic changes during disease progression

open access: yesMolecular Oncology, EarlyView.
Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

The role of m6A RNA methylation in human cancer

open access: yesMolecular Cancer, 2019
N6-methyladenosine (m6A) is identified as the most common, abundant and conserved internal transcriptional modification, especially within eukaryotic messenger RNAs (mRNAs).

Integrative analysis of circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients: a comprehensive approach

open access: yesMolecular Oncology, EarlyView.
This study simultaneously investigated circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients. The elevated expression of JUNB and CXCR4 in CTCs was a poor prognostic factor for SCLC patients, whereas exosomal overexpression of these biomarkers revealed a high discrimination ability of patients from healthy individuals,

Impact of cytosine methylation on DNA binding specificities of human transcription factors

open access: yesScience, 2017
Positives and negatives of methylated CpG When the DNA bases cytosine and guanine are next to each other, a methyl group is generally added to the pyrimidine, generating a mCpG dinucleotide.
