Botrytis cinerea is a phytopathogenic fungi causing disease in a number of important crops. It is considered a very complex species in which different populations seem to be adapted to different hosts. In order to characterize fungal virulence factors, a proteomic research was started. A protocol for protein extraction from mycelium tissue, with protein(More)
OBJECTIVE Adult mesenchymal stem cells (MSCs) are multipotent cells whose primary reservoir is bone marrow (BM). Following situations of extensive tissue damage, MSCs are mobilized and migrate to the site of injury. Osteoarthritis (OA) is a condition that involves extensive cartilage and bone damage. To gain insight into the pathogenesis of OA, we have(More)
The bacteriocinogenic strain of Enterococcus faecalis EJ97 has been isolated from municipal waste water. It produces a cationic bacteriocin (enterocin EJ97) of low molecular mass (5,340 Da) that is very stable under mild heat conditions and is sensitive to proteolytic enzymes. The amino acid sequence of the first 18 N-terminal residues of enterocin EJ97(More)
Plum pox virus (PPV) is a member of the Potyvirus genus of plant viruses. Labeling with UDP-[3H]galactose and galactosyltransferase indicated that the capsid protein (CP) of PPV is a glycoprotein with N-acetylglucosamine terminal residues. Mass spectrometry analysis of different PPV isolates and mutants revealed O-linked N-acetylglucosamination, a(More)
Changes in the outer membrane subproteome of Escherichia coli along the transition to the viable but nonculturable state (VBNC) were studied. The VBNC state was triggered by exposure of E. coli cells to adverse conditions such as aquatic systems, starvation, suboptimal temperature, visible light irradiation and seawater. The subproteome, obtained according(More)
As a global approach to gain a better understanding of the mechanisms involved in pea resistance to Erysiphe pisi, changes in the leaf proteome of two pea genotypes differing in their resistance phenotype were analyzed by a combination of 2-DE and MALDI-TOF/TOF MS. Leaf proteins from control non-inoculated and inoculated susceptible (Messire) and resistant(More)
Protein phosphorylation affects most eukaryotic cellular processes and its deregulation is considered a hallmark of cancer and other diseases. Phosphoproteomics may enable monitoring of altered signaling pathways as a means of stratifying tumors and facilitating the discovery of new drugs. Unfortunately, the development of molecular tests for clinical use(More)
A cocktail sandwich ELISA based on the employ of two monoclonal antibodies (MAbs) as coating antibodies and a third MAb conjugated to horseradish peroxidase has been developed for the analysis of gluten in foods. Given that each MAb displays a wide specificity spectrum for wheat, barley, rye and oats prolamins, their combination for ELISA ensures a high(More)
Human mesenchymal stem cells (MSC) have been on the focus of intense clinical-oriented research due to their multilineage differentiation potential and immunomodulatory properties. However, to reach the clinically meaningful cell numbers for cellular therapy and tissue engineering applications, MSC ex-vivo expansion is mandatory but sequential cell(More)
The tetralin biodegradation pathway in Rhodococcus sp. strain TFB, a Gram-positive bacterium resistant to genetic manipulation, was characterized using a proteomic approach. Relative protein expression in cell free extracts from tetralin- and glucose-grown cells was compared using the 2D-DIGE technique. Identification of proteins specifically expressed in(More)
