The use of immunodeficient mice, particularly of the nonobese diabetic/severe combined immunodeficient (NOD/SCID) strain, has allowed detection of very primitive malignant progenitors from patients with acute myelogenous leukemia (AML). To define the sensitivity and reproducibility with which the engraftment of different AML cells can be detected, 61(More)
To explore the possibility that deregulated HOX gene expression might commonly occur during leukemic hematopoiesis, we compared the relative levels of expression of these and related genes in phenotypically and functionally defined subpopulations of AML blasts and normal hematopoietic cells. Initially, a semi-quantitative RT-PCR technique was used to(More)
Conventional N-methyl-D-aspartate (NMDA) receptor (NMDAR) is a heteromeric complex between the essential NR1 subunit and one of NR2A-D subunits toward functional channels permeable to Ca(2+) rather than Na(+) ions. Although recent studies identified dominant negative NR3A and NR3B subunits, whether these subunits inhibit Ca(2+) mobilization through NMDAR(More)
The underlying mechanisms are still unclear for the neuroprotective properties of nicotine to date, whereas we have shown functional expression of nicotinic acetylcholine receptors (nAChRs) responsible for the influx of extracellular Ca(2+) in cultured rat cortical astrocytes. In this study, we investigated the possible involvement of astrocytic nAChRs in(More)
We have previously demonstrated the functional expression of glutamine (Gln) transporter (GlnT) believed to predominate in neurons for the neurotransmitter glutamate pool by rat neocortical astrocytes devoid of neuronal marker expression, with exacerbated vulnerability to oxidative stress after transient overexpression. To evaluate molecular mechanisms(More)
Cell surface protein antigen (PAc) and glucosyltransferases (GTF) produced by Streptococcus mutans are considered major colonization factors of the organism, and the inhibition of these factors is thought to prevent dental caries. In this study, 8-mo-old pregnant Holstein cows were immunized with fusion protein PAcA-GB, a fusion of the saliva-binding(More)
