PST1 and ECM33 encode two yeast cell surface GPI proteins important for cell wall integrity

, 2004
Pst1p was previously identified as a protein secreted by yeast regenerating protoplasts, which suggests a role in cell wall construction. ECM33 encodes a protein homologous to Pst1p, and both of them display typical features of GPI-anchored proteins and a

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Staphylococcus aureus: salt stress, cell wall deficiency, and Biofílm formation [PDF]

, 2008
Staphylococcus aureus (S. aureus) is a major cause of chronic infection and is of particular concern in the infection of implanted prostheses. Biofilm formation offers bacteria innate protection from antimicrobial agents and prevents the eradication of ...

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Identification of Cell Wall-Associated Proteins from Phytophthora ramorum

Molecular Plant-Microbe Interactions, 2006
The oomycete genus Phytophthora comprises a large group of fungal-like plant pathogens. Two Phytophthora genomes recently have been sequenced; one of them is the genome of Phytophthora ramorum, the causal agent of sudden oak death. During plant infection,

Lipopolysaccharide uptake is augmented in lipopolysaccharide‐tolerant mouse macrophage‐like cells via increased CD14 expression

FEBS Open Bio, EarlyView.
In normal (nontolerant) cells, CD14 is crucial for both LPS uptake and LPS signaling. In LPS‐tolerant cells, in which LPS‐induced TNF‐α and IFN‐β production is suppressed, there is a dramatic increase in surface CD14 expression. The overexpressed CD14 in LPS‐tolerant cells is responsible for the enhanced LPS uptake without inducing pro‐inflammatory ...

Cell Wall Extensibility and Effect of Cell-Wall-Loosening Proteins during Rose Flower Opening

Journal of the Japanese Society for Horticultural Science, 2009
As flower opening involves the expansion of petal cells, the mechanisms of expansion growth were investigated in Rosa hybrida L. 'FEbesa' (syn. 'Pretty Woman') petals. Petal cell-wall extensibility was analyzed by creep extension analysis. Walls of the petal cells became loose at developing stage IV of completely separated sepals on an opening flower ...

A study of the molecular pathways of wood formation using peptide mass spectrometry [PDF]

, 2010
Wood consists essentially of secondary plant cell walls, composed of a cellulose and hemicellulose network impregnated with lignin. It is formed via the development of derivatives of a thin layer of cells (the vascular cambium) into xylem cells through ...

Dimeric structure of the bacterial extracellular foldase PrsA [PDF]

, 2015
Secretion of proteins into the membrane-cell wall space is essential for cell wall biosynthesis and pathogenicity in Gram-positive bacteria. Folding and maturation of many secreted proteins depend on a single extracellular foldase, the PrsA protein. PrsA

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.
