Cell‐free DNA as a biomarker of aging [PDF]

open access: yesAging Cell, 2018
AbstractCell‐free DNA (cfDNA) is present in the circulating plasma and other body fluids and is known to originate mainly from apoptotic cells. Here, we provide the first in vivo evidence of global and local chromatin changes in human aging by analyzing cfDNA from the blood of individuals of different age groups.

Circulating biomarkers to monitor cancer progression and treatment

open access: yesComputational and Structural Biotechnology Journal, 2016
Tumor heterogeneity is a major challenge and the root cause of resistance to treatment. Still, the standard diagnostic approach relies on the analysis of a single tumor sample from a local or metastatic site that is obtained at a given time point. Due to

DNA methylation analysis explores the molecular basis of plasma cell-free DNA fragmentation

open access: yesNature Communications, 2023
Plasma cell-free DNA (cfDNA) are small molecules generated through a non-random fragmentation procedure. Despite commendable translational values in cancer liquid biopsy, however, the biology of cfDNA, especially the principles of cfDNA fragmentation ...

Single Cell Analysis of Human RAD18-Dependent DNA Post-Replication Repair by Alkaline Bromodeoxyuridine Comet Assay [PDF]

open access: yes, 2013
Damage to DNA can block replication progression resulting in gaps in the newly synthesized DNA. Cells utilize a number of post-replication repair (PRR) mechanisms such as the RAD18 controlled translesion synthesis or template switching to overcome the ...

Multimodal analysis of cell-free DNA whole-genome sequencing for pediatric cancers with low mutational burden

open access: yesNature Communications, 2021
Sequencing of cell-free DNA in the blood of cancer patients (liquid biopsy) provides attractive opportunities for early diagnosis, assessment of treatment response, and minimally invasive disease monitoring. To unlock liquid biopsy analysis for pediatric

Biochemical and clinical diagnostic aspects of circulating nucleic acids [PDF]

open access: yes, 2005
We investigated the size distribution of fetal DNA using a combination of agorose gel electrophoresis, Southern blot and real time PCR assay. Our results showed plasma DNA presents apoptotic characteristics and the cell free fetal DNA is generally ...

High-intensity sequencing reveals the sources of plasma circulating cell-free DNA variants

open access: yesNature Medicine, 2019
Accurate identification of tumor-derived somatic variants in plasma circulating cell-free DNA (cfDNA) requires understanding of the various biological compartments contributing to the cfDNA pool.

Limitations and opportunities of technologies for the analysis of cell-free DNA in cancer diagnostics

open access: yesNature Biomedical Engineering, 2022
Cell-free DNA (cfDNA) in the circulating blood plasma of patients with cancer contains tumour-derived DNA sequences that can serve as biomarkers for guiding therapy, for the monitoring of drug resistance, and for the early detection of cancers.
