Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Double Stranded RNA in Human Seminal Plasma

Frontiers in Genetics, 2017
Recently, human semen was shown to contain cell-free nucleic acids, such as DNA, long single stranded RNA, and small RNAs–miRNA and piRNA. The RNAs have been suggested to have potential biological roles as communication molecules between cells and in the

Extraction of Proteins and Other Intracellular Bioactive Compounds From Baker’s Yeasts by Pulsed Electric Field Treatment

Frontiers in Bioengineering and Biotechnology, 2020
Yeasts are rich source of proteins, antioxidants, vitamins, and other bioactive compounds. The main drawback in their utilization as valuable ingredients in functional foods and dietary supplements production is the thick, indigestible cell wall, as well

Automated design of protein-binding riboswitches for sensing human biomarkers in a cell-free expression system

Nature Communications, 2023
Cell-free genetically encoded biosensors have been developed to detect small molecules and nucleic acids, but they have yet to be reliably engineered to detect proteins.

Impact of PNKP mutations associated with microcephaly, seizures and developmental delay on enzyme activity and DNA strand break repair [PDF]

, 2012
Microcephaly with early-onset, intractable seizures and developmental delay (MCSZ) is a hereditary disease caused by mutations in polynucleotide kinase/phosphatase (PNKP), a DNA strand break repair protein with DNA 5'-kinase and DNA 3'-phosphatase ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Circulating Cell-Free Nucleic Acid Detection for Wuchereria bancrofti Infections

The Journal of Infectious Diseases
Abstract Human lymphatic filariasis (LF) is primarily caused by the helminth parasites Wuchereria bancrofti (Wb) and Brugia malayi (Bm). Detecting parasitic circulating cell-free nucleic acids (ccfDNA/ccfRNA) in plasma is a promising approach for detection of active infections.

New indicator of cellular ischemia in coronary slow-flow phenomenon: Cell-free DNA

Türk Kardiyoloji Derneği Arşivi, 2020
Objective: Coronary slow-flow phenomenon (CSFP) is defined as the delayed arrival of coronary blood flow to the distal vascular bed in at least 1 major epicardial coronary artery. Cell-free DNA (cfDNA) is a type of DNA that circulates freely in the blood

Pathogen- and Host-Directed Antileishmanial Effects Mediated by Polyhexanide (PHMB) [PDF]

, 2015
BACKGROUND:Cutaneous leishmaniasis (CL) is a neglected tropical disease caused by protozoan parasites of the genus Leishmania. CL causes enormous suffering in many countries worldwide. There is no licensed vaccine against CL, and the chemotherapy options
