M P Molloy et al.
Electrophoresis, 19(5), 837-844 (1998-06-18)
We describe the extraction and enrichment of membrane proteins for separation by two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) after differential solubilization of an Escherichia coli cell lysate. In a simple three-step sequential solubilization protocol applicable for whole cell lysates, membrane...

Sulfonylureas (SUs) have been suggested to have an insulin-independent blood glucose-decreasing activity due to an extrapancreatic effect. However, a lack of adequate in vivo evidence makes this statement controversial. Here, we aimed to evaluate whether glimepiride has extrapancreatic blood glucose-lowering...

Gastroenterology, 140(2), 550-559 (2010-11-09)
Interactions between lymphocytes and intestinal epithelial cells occur in the subepithelial space of the gastrointestinal tract. Normal human lamina propria lymphocytes (LPLs) induce differentiation of intestinal epithelial cells. The absence of LPLs in mice, such as in RAG1(-/-) mice, results...

Raccoon dog is one of the suspected intermediate hosts of severe acute respiratory syndrome coronavirus (SARS-CoV). In this study, the angiotensin-converting enzyme 2 (ACE2) gene of raccoon dog (rdACE2) was cloned and sequenced. The amino acid sequence of rdACE2 has...

Electrophoresis, 32(24), 3621-3629 (2011-11-22)
Performing 2-DE of lipid-rich multilamellar membranes like myelin is a cumbersome task. However, for understanding its molecular organization and changes during diseases, identification of proteins of myelin is essential. Although the 2-D-proteomic approach of myelin has been employed to understand...

With the aim of studying differentially expressed proteins as a function of abiotic and biotic stress in citrus plants, we optimized a protocol for the extraction of total leaf proteins and their 2-DE separation using commercially available immobilized pH gradient...
B R Herbert et al.
Electrophoresis, 19(5), 845-851 (1998-06-18)
In this study, dithiothreitol was replaced by tributyl phosphine as the reducing agent in both the sample solution for the first-dimensional isoelectric focusing and during the immobilised pH gradient (IPG) equilibration procedure. Tributyl phosphine improves protein solubility during isoelectric focusing...

Mycoplasmas are the simplest bacteria capable of autonomous replication. Their evolution proceeded from gram-positive bacteria, with the loss of many biosynthetic pathways and of the cell wall. In this work, the liposoluble protein complement of Mycoplasma agalactiae, a minimal bacterial...

Analytical biochemistry, 377(2), 134-140 (2008-04-04)
We investigate the selectivity achieved after differential solubilization of bacterial proteomes following two procedures, both based on successive extraction of proteins in solutions of increasing solubilizing power. Recently, these procedures have gained notable popularity and several commercial kits are now...

Journal of chromatography. A, 1153(1-2), 235-258 (2007-02-06)
Sample preparation is a fundamental step in the proteomics workflow. However, it is not easy to find compiled information updating this subject. In this paper, the strategies and protocols for protein extraction and identification, following either classical or second generation...

Escherichia coli O157:H7 causes hemorrhagic colitis and hemolytic-uremic syndrome in humans, and its major reservoir is healthy cattle. An F-like 92-kb plasmid, pO157, is found in most E. coli O157:H7 clinical isolates, and pO157 shares sequence similarities with plasmids present...

Applied and environmental microbiology, 74(16), 5015-5022 (2008-06-17)
Escherichia coli O157:H7 causes hemorrhagic colitis and the life-threatening hemolytic-uremic syndrome in humans and transiently colonizes healthy cattle at the terminal rectal mucosa. To investigate the role of the O antigen in persistence and colonization in the animal host, we...

Fetuin-A is a known inhibitor of vascular calcification in vitro. In arteries with calcification, there is increased immunostaining for fetuin-A. However, vascular smooth muscle cells (VSMC) do not synthesize fetuin-A, suggesting fetuin-A may be endocytosed to exert its inhibitory effects....

Antarctic bacteria are adapted to the extremely low temperature. The transcriptional and translational machineries of these bacteria are adapted to the sub-zero degrees of temperature. Studies directed towards identifying the changes in the protein profiles during changes in the growth...

Inorganic phosphate (Pi) transporters (PTs) play vital roles in Pi uptake and translocation in plants. Under Pi sufficient conditions, PTs are degraded to prevent excess Pi accumulation. The mechanisms targeting PTs for degradation are not fully elucidated. In this study...

The mechanisms underlying the autonomous accumulation of malignant B cells remain elusive. We show in this study that non-Hodgkin's lymphoma (NHL) B cells express B cell-activating factor of the TNF family (BAFF) and a proliferation-inducing ligand (APRIL), two powerful B...
