Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

EQCM and EIS Study of the Effect of Potential of Zero Charge on Escherichia Coli Biofilm Development

International Journal of Electrochemical Science, 2010
Using EQCM method, the influence of electrode potential on Escherichia coli (E. coli) biofilm development was investigated in a range from −0.6V to 0.6V. Parabolic dependence of the cell density on the electrode potential was observed.

Systematic derivation of a surface polarization model for planar perovskite solar cells [PDF]

, 2017
Increasing evidence suggests that the presence of mobile ions in perovskite solar cells can cause a current-voltage curve hysteresis. Steady state and transient current-voltage characteristics of a planar metal halide CH$_3$NH$_3$PbI$_3$ perovskite solar

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Transition from ultrafast laser photo-electron emission to space charge limited current in a 1D gap

, 2014
A one-dimensional (1D) model has been constructed to study the transition of the time-dependent ultrafast laser photo-electron emission from a flat metallic surface to the space charge limited (SCL) current, including the effect of non-equilibrium laser ...

Zeta potential change of Neuro-2a tumor cells after exposure to alumina nanoparticles [PDF]

, 2016
In recent years, researches have paid much attention to the physical, chemical, biophysical and biochemical properties of a cell surface. It is known that most of the cells’ surfaces are charged.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Effects of paclitaxel nanocrystals surface charge on cell internalization

European Journal of Pharmaceutical Sciences, 2016
In this study, we investigated the influence of paclitaxel nanocrystals (PTX-NC) surface charge on cell internalization and cell cytotoxicity. PTX-NCs were prepared using the nano-precipitation method. The surface-modified PTX-NCs were prepared using an absorption method with positively charged poly(allylamine hydrochloride) (PAH) and negatively ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
