Introduction. Both recurrent depressive disorders and affective bipolar disorders are characterized by the changes in glial tissue. S100B protein is a calcium-binding molecule, mainly secreted by glial cells, which, depending on its concentration, has a trophic or toxic effect on neuronal cells. In the recent years, due to the postulated glial hypothesis of affective disorders and the ideas con...

BACKGROUND The on-field diagnosis of sports-related concussion (SRC) is complicated by the lack of an accurate and objective marker of brain injury. PURPOSE To compare subject-specific changes in the astroglial protein, S100B, before and after SRC among collegiate and semi-professional contact sport athletes, and compare these changes to differences in S100B before and after non-contact exert...

Malignant melanoma continues to be an extremely fatal cancer due to a lack of viable treatment options for patients. The calcium-binding protein S100B has long been used as a clinical biomarker, aiding in malignant melanoma staging and patient prognosis. However, the discovery of p53 as a S100B target and the consequent impact on cell apoptosis redirected research efforts towards the developmen...

Our aim was to investigate the expression of S100B protein in the amnion and to assess the amniotic fluid concentration in pregnancies complicated by pre-eclampsia. Samples were obtained from women who developed pre-eclampsia (n = 7), pre-eclampsia with intrauterine growth retardation (IUGR) (n = 4), normotensive IUGR (n = 7) and gestational hypertension (n = 4) during pregnancy and healthy con...

This study aims to explore the relation between changes in myelin basic protein (MBP) and S100 protein (S100B) serum levels and prognosis in premature infants with periventricular leukomalacia (PVL). In our hospital, 78 premature infants with PVL and 43 normal premature infants were studied from July 1, 2007 to December 31, 2008. MBP and S100B serum levels were detected at 1, 3, 7, and 14 days ...

Neuroinflammation is one of the major players in amyotrophic lateral sclerosis (ALS) pathogenesis, and astrocytes are significantly involved in this process. The astrocytic protein S100B can be released in pathological states activating the receptor for advanced glycation end products (RAGE). Different indications point to an aberrant expression of S100B and RAGE in ALS. In this work, we observ...

BACKGROUND S100B is a calcium-binding protein, belonging to the S100 family proteins which are characterized by their high solubility and, currently, comprises 21 members which are expressed in a cell-specific manner. If we can predict the possibility of definite brain death after brain injury, we will rescue some organs of body to transplant proposes. OBJECTIVES In this regard our study focu...

PURPOSE Interleukin-1beta (IL-1beta) and S100B calcium binding protein B (S100B) have been implicated in the pathogenesis of Alzheimer's disease. Both are present in and around senile plaques and have been shown to increase levels of amyloid precursor protein (APP) mRNA in vitro. However, it is not known how either of these substances affects APP in vivo. METHODS We have studied the effects o...

S100B is a protein with dose-dependent neurotrophic and neurotoxic effects. Whether S100B in psychotic disorder mirrors pathophysiological mechanisms (which elicit exacerbation of disease) or compensatory action is unclear, as is its validity as a proxy marker for brain status. Insight may be gained by examining associations between serum S100B and indices of grey (cortical thickness (CT)) and ...

Increasing evidence suggests that the small EF-hand calcium-binding protein S100B plays an important role in Alzheimer's disease. Among other evidences are the increased levels of both S100B and its receptor, the Receptor for Advanced Glycation Endproducts (RAGEs) in the AD diseased brain. The regulation of RAGE signaling by S100B is complex and probably involves other ligands including the amy...
