Functional capacity of Shiga-toxin promoter sequences in eukaryotic cells. [PDF]

open access: yesPLoS ONE, 2013
Shiga toxins (Stx) are the main virulence factors in enterohemorrhagic Escherichia coli (EHEC) infections, causing diarrhea and hemolytic uremic syndrome (HUS). The genes encoding for Shiga toxin-2 (Stx2) are located in a bacteriophage.

Translation inhibition by rocaglates is independent of eIF4E phosphorylation status [PDF]

open access: yes, 2016
Rocaglates are natural products that inhibit protein synthesis in eukaryotes and exhibit antineoplastic activity. In vitro biochemical assays, affinity chromatography experiments coupled with mass spectrometry analysis, and in vivo genetic screens have ...

Origin of the Eukaryotic Cell

open access: yesMolecular Frontiers Journal, 2017
All complex life on Earth is composed of ‘eukaryotic’ cells. Eukaryotes arose just once in 4 billion years, via an endosymbiosis — bacteria entered a simple host cell, evolving into mitochondria, the ‘powerhouses’ of complex cells. Mitochondria lost most of their genes, retaining only those needed for respiration, giving eukaryotes ‘multi-bacterial ...

The Membranes of a Eukaryotic Cell [PDF]

open access: yesAmerican Zoologist, 1989
Synopsis. The evolution of internal membrane systems has introduced many additional control steps into pathways that, although basically similar in prokaryotic cells, are less sophisticated and leave many aspects up to chance. Temporal and spatial control of secre? tion, quality control of the proteins secreted or inserted into the plasma membrane, and

Orchestrated transcription of biological processes in the marine picoeukaryote Ostreococcus exposed to light/dark cycles [PDF]

open access: yes, 2010
Background: Picoeukaryotes represent an important, yet poorly characterized component of marine phytoplankton. The recent genome availability for two species of Ostreococcus and Micromonas has led to the emergence of picophytoplankton comparative ...

A trans-kingdom T6SS effector induces the fragmentation of the mitochondrial network and activates innate immune receptor NLRX1 to promote infection

open access: yesNature Communications, 2023
Bacteria can affect cellular processes in other bacteria and in eukaryotic cells by injecting effectors using a type VI secretion system (T6SS). Here, Sá-Pessoa et al.

Interaction of bacterial extracellular microvesicles with eukaryotic cells.

open access: yesМедицинская иммунология, 2021
Bacterial extracellular microvesicles (BMV) are formed by nonpathogenic, pathogenic and opportunistic bacteria. BMV are spherical bilayer-membrane organelles containing different cargoes: lipopolysaccharides, pathogen associated molecular patterns (PUMP),

Mad2, Bub3, and Mps1 regulate chromosome segregation and mitotic synchrony in Giardia intestinalis, a binucleate protist lacking an anaphase-promoting complex. [PDF]

open access: yes, 2014
The binucleate pathogen Giardia intestinalis is a highly divergent eukaryote with a semiopen mitosis, lacking an anaphase-promoting complex/cyclosome (APC/C) and many of the mitotic checkpoint complex (MCC) proteins.

An ABC transporter containing a forkhead-associated domain interacts with a serine-threonine protein kinase and is required for growth of Mycobacterium tuberculosis in mice [PDF]

open access: yes, 2005
Forkhead-associated (FHA) domains are modular phosphopeptide recognition motifs with a striking preference for phosphothreonine-containing epitopes. FHA domains have been best characterized in eukaryotic signaling pathways but have been identified in six

Circulating histones as clinical biomarkers in critically ill conditions

open access: yesFEBS Letters, EarlyView.
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.
