CONTEXT Clinical and experimental studies have suggested a link between S100 gene ex-pression and neoplastic disorders, however, the molecular mechanisms of this associa-tion are not well understood. The aim of this review was to conduct a comprehensive literature search in order to understand the possible underlying molecular mechanisms of this association. We also discuss their application as...

The aim of this study was to investigate whether the use of sainfoin-based condensed tannins (CT) enhances feed value when given with tannin-free legumes (lucerne) to sheep. The experiments were conducted with fresh sainfoin and lucerne harvested at two stages (vegetative stage as compared with early flowering) in the first growth cycle. Fresh sainfoin and lucerne forages were combined in ratio...

Neuroinflammation is a hallmark of Amyotrophic Lateral Sclerosis (ALS) in hSOD1G93A mouse models where microglial cells contribute to the progressive motor neuron degenerative process. S100-A8 and S100-A9 (also known as MRP8 MRP14, respectively) are cytoplasmic proteins expressed by inflammatory myeloid cells, including microglia macrophages. Mainly acting heterodimer, S100-A8/A9, when secreted...

INTRODUCTION Admission to the intensive care unit (ICU) may be preceded by dramatic events leading to permanent neurological injury. Plasma S100 protein levels are proved to be clinically useful in predicting neurological outcome following cardiac arrest. It is unclear, however, whether this may be extrapolated to a broader population of ICU patients. AIM To assess the utility of plasma S100 ...

exchange chromatography (1, 3). Purified dimeric S100 proteins were characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and their metal-binding and immunologic properties. The exact masses of S100 proteins were determined by electrospray ionization mass spectrometry (SCIEX API 365; Perkin-Elmer). Native proteins (in contrast to the recombinant proteins) were found to be m...

BACKGROUND Periodontal inflammation is characterized by injuries in collagen, epithelial, bone tissues. The hypotheses to be tested were relationship between the s100, bcl2 and myeloperoxidase in gingival tissues (MPO does affect the level of s100, bcl2). The object of this study was to investigate of s100 expression, bcl2 expression and myeloperoxidase expression in periodontal inflammation. ...

Multidimensional LC-MS/MS has been used for the analysis of biological samples labeled with isobaric mass tags for relative and absolute quantitation (iTRAQ) to identify proteins that are differentially expressed in human head-and-neck squamous cell carcinomas (HNSCCs) in relation to non-cancerous head-and-neck tissues (controls) for cancer biomarker discovery. Fifteen individual samples (cance...

S100 proteins belong to the EF-hand Ca(2+ )-binding protein family and regulate a variety of cellular processes via interaction with different target proteins. Several diseases, including cancer and melanoma, are related to the abnormal expression of S100 proteins, which are expressed in cell- and tissue-specific manners. We investigated the expression of S100 family members in human uterine sm...

BACKGROUND In uncommon mucosal melanomas of the head and neck established prognostic factors are rare and controversially discussed. The purpose of this study was to evaluate outcome and value of S100/podoplanin and S100/CD31 double immunostaining in head and neck mucosal melanomas. METHODS Retrospectively, patients with head and neck mucosal melanomas treated between 1973 and 2008 were analy...

Changes in cytosolic Ca2+ concentration control a wide range of cellular responses, and intracellular Ca2+-binding proteins are the key molecules to transduce Ca2+ signaling via interactions with different types of target proteins. Among these, S100 Ca2+-binding proteins, characterized by a common structural motif, the EF-hand, have recently attracted major interest due to their cell- and tissu...
