Calretinin is a 29-kDa calcium-binding protein abundantly expressed in central and peripheral neural tissues. The aim here was to determine its expression during various stages of odontogenesis. Five categories of embryonic (E) and postnatal (P) rats at various ages (E17, E18, E20, P0, and P7), both male and female, were used to represent the various stages(More)
The molecular mechanisms responsible for differential neuronal vulnerability to ischemic injury are incompletely understood. Previous studies have reported that the expression and activity of protein kinase C (PKC), some subtypes of which are activated by Ca(2+) and diacylglycerol (DG), are altered after ischemic insults. Therefore, DG kinase (DGK), which(More)
AIMS Calretinin, a 29-kDa calcium-binding protein is expressed widely in normal human tissues and tumours including both unicystic and solid and multicystic ameloblastomas. The histological distinction between unicystic ameloblastomas and certain non-neoplastic odontogenic cysts can be problematic. The objective of this study was to determine whether(More)
Diacylglycerol kinase (DGK) is an enzyme that phosphorylates a second messenger diacylglycerol (DG) and is involved in a variety of pathophysiological cellular responses. We have previously reported that DGKzeta may be involved in the selective vulnerability of hippocampal CA1 neurons in transient forebrain ischemia. In this study we aimed to further(More)
OBJECT Neural stem cells (NSCs) have been demonstrated in the subventricular zone (SVZ) of the lateral ventricle and the subgranular zone of the hippocampal dentate gyrus (DG). Although aging rats manifest a decrease in NSCs, rats exposed to stress (for example, ischemia, epilepsy, radiation, and trauma) show an increase in these cells. In transgenic mice,(More)
AIMS Alpha glutathione S-transferase (alpha-GST) has been shown to be an immunohistochemical marker for delta(4-5) isomerase, an enzyme active in steroidogenesis. The purpose of this study was to document the distribution of alpha-GST in ovarian neoplasms in order to evaluate its usefulness as a diagnostic tool. METHODS AND RESULTS A total of 92 tumours(More)
