Clathrate formation and dissociation in vapor/water/ice/hydrate systems in SBA-15, sol-gel and CPG porous media, as probed by NMR relaxation, novel protocol NMR cryoporometry, neutron scattering and ab initio quantum-mechanical molecular dynamics simulation [PDF]
, 2007 The Gibbs-Thomson effect modifies the pressure and temperature at which clathrates occur, hence altering the depth at which they occur in the seabed. Nuclear magnetic resonance (NMR) measurements as a function of temperature are being conducted for water/

Reduction of dimensionality in Karyopherinβ1 mediated transport on FG domains [PDF]
, 2014 Many molecular transport processes in living cells proceed by facilitated diffusion in two dimensions instead of three, but how this process works remains poorly understood.

The nuclear pore‐targeting complex binds to nuclear pores after association with a karyophile [PDF]
FEBS Letters, 1995 We recently showed that a karyophilic protein forms a stable complex, termed nuclear pore‐targeting complex (PTAC), with cytoplasmic components prior to nuclear porebinding. In this study, we cloned a cDNA encoding a 97 kDa of PTAC (PTAC97). Recombinant PTAC97 completely reconstitutes the nuclear binding‐step in conjunction with a 58 kDa component of ...

Heat-induced gene positioning in "Caenorhabdidtis elegans" : "hsp-16" promoter drives transcription-dependent nuclear pore association [PDF]
, 2013 The DNA of eukaryotic cells is packaged into transcriptionally active euchromatin and repressed heterochromatin. These two chromatin types are non-randomly distributed within the nucleus. Indeed, at the nuclear periphery, heterochromatin is enriched near

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Silencing nuclear pore protein Tpr elicits a senescent-like phenotype in cancer cells.
PLoS ONE, 2011 BackgroundTpr is a large coiled-coil protein located in the nuclear basket of the nuclear pore complex for which many different functions were proposed from yeast to human.Methodology/principal findingsHere we show that depletion of Tpr by RNA ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Structural and functional characterization of the p62 complex, a subcomplex of the nuclear pore complex [PDF]
, 2008 The nuclear pore complex (NPC) is a highly conserved eukaryotic protein complex, which perforates the nuclear envelope and regulates nucleocytoplasmic transport of cargos between the cytoplasm and nucleus.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
