Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Systematic determination of the mosaic structure of bacterial genomes: species backbone versus strain-specific loops [PDF]

, 2005
Background Public databases now contain multitude of complete bacterial genomes, including several genomes of the same species. The available data offers new opportunities to address questions about bacterial genome evolution, a task that requires ...

Oral bacterial DNA findings in pericardial fluid

Journal of Oral Microbiology, 2014
Background: We recently reported that large amounts of oral bacterial DNA can be found in thrombus aspirates of myocardial infarction patients. Some case reports describe bacterial findings in pericardial fluid, mostly done with conventional culturing ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Expression in mammalian cells of a cloned gene encoding murine DNA methyltransferase [PDF]

, 1991
Mammalian DNA cytosine-5-methyltransferase (MTase, EC 2.1.1.37) is an essential component for establishing and maintaining cell-type specific methylation patterns in the genome. The cDNAfor the murine enzyme was previously cloned in segments.

DNA extraction: High yield is not synonymous with high diversity

Bioingeniøren, 2017
The quality, amount, and, in the case of polymicrobial samples, diversity of isolated DNA presupposes the precision of downstream application results. As part of a larger study on colorectal cancer, the aim of this work was to identify the DNA extraction

DNA Wrapping by a tetrameric bacterial histone

Nature Communications
Abstract Histones are conserved DNA-packaging proteins found across all domains of life. In eukaryotes, canonical histones form octamers that wrap ~147 base pairs (bp) of DNA into nucleosomes, while in archaea they form dimers that polymerize into extended hypernucleosomes.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

The characterisation of polymicrobial bacterial communities in the lower respiratory tract of individuals with chronic pulmonary disease [PDF]

Microbial diversity encompasses the whole of the Earth’s biosphere and is incredibly vast. The microbial diversity of three disparate micro-environments using two culture-independent techniques (denaturing gradient gel electrophoresis (DGGE) and 454 ...
