Sizing Up Cell-Free DNA [PDF]

open access: yesClinical Chemistry, 2012
In 1947, Mandel and Metais discovered the unusual phenomenon of circulating cell-free DNA (1). Although one might naively think that DNA is found only in the nuclei of cells, it turns out that a substantial amount of small DNA fragments circulates within the blood.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Cell-free DNA testing: future applications in gastroenterology and hepatology

open access: yesTherapeutic Advances in Gastroenterology, 2019
The application of next-generation sequencing in clinical practice is increasing as accuracy and interpretation have improved and the cost continues to decline rapidly.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Circulating cell-free DNA levels correlate with postresuscitation survival rates in out-of-hospital cardiac arrest patients

open access: yes, 2014
Early prediction of prognosis is helpful in cardiac arrest patients. Plasma cell-free DNA, which increases rapidly after cell death, is a novel biomarker for the prognosis of critical ill patients.

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 ...

Cell-Free DNA Fragmentomics in Liquid Biopsy

open access: yesDiagnostics, 2022
Cell-free DNA (cfDNA) in bodily fluids has rapidly transformed the development of noninvasive prenatal testing, cancer liquid biopsy, and transplantation monitoring. Plasma cfDNA consists of a mixture of molecules originating from various bodily tissues.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.
