Cryo-EM structures of the eukaryotic replicative helicase bound to a translocation substrate

Nature Communications, 2016
The Cdc45-MCM-GINS (CMG) helicase unwinds DNA during replication, a process that requires the ATPase-dependent activity of the MCM complex. Using cryo-EM reconstructions of the CMG complex in different conformations, the authors propose a model where the

High-Speed Single-Molecule Tracking of CXCL13 in the B-Follicle

Frontiers in Immunology, 2018
Soluble factors are an essential means of communication between cells and their environment. However, many molecules readily interact with extracellular matrix components, giving rise to multiple modes of diffusion.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Incoherent x-ray scattering in single molecule imaging

New Journal of Physics, 2014
Imaging of the structure of single proteins or other biomolecules with atomic resolution would be enormously beneficial to structural biology. X-ray free-electron lasers generate highly intense and ultrashort x-ray pulses, providing a route towards ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Quantification of Receptor Targeting Aptamer Binding Characteristics Using Single-Molecule Spectroscopy [PDF]

, 2011
This experimental design presents a single molecule approach based on fluorescence correlation spectroscopy (FCS) for the quantification of outer membrane proteins which are receptors to an aptamer specifically designed to target the surface receptors of

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Single-molecule microscopy study of nano-systems [PDF]

, 2011
In this work, techniques were developed and used to study the properties of molecules on a single-molecule level. Single-molecule techniques have the major advantage, that in contrast to ensemble measurements, they allow a detailed insight on the ...
