The connection between the regulation of L-arginine transport and nitric oxide (NO) synthesis was studied in rat alveolar macrophages. Lipopolysaccharides (LPSs) and interferon-gamma stimulated in the same concentration- and time-dependent manner NO synthesis (measured by nitrite accumulation) and L-[(3)H]arginine uptake. This correlated with an increased mRNA expression for iNOS and the cation...
Interferon-alpha 2b is not effective in the treatment of refractory immune thrombocytopenic purpura.
About 25-30% of patients with immune thrombocytopenic purpura (ITP) are refractory to corticosteroids, splenectomy and other treatments. It has been suggested that interferon-alpha 2b (IFN-alpha 2b) may be useful in the treatment of chronic refractory ITP patients. We treated 9 chronic refractory ITP patients with IFN-alpha 2b: the results were poor.
Transmission electron microscopy was used to determine how immunogold labeling of PKC-alpha or -beta is modulated by the antitumor drug IFN (HuIFN alpha-2b) in the cytoplasm, membrane structures, and nucleus of rapidly dividing and confluent human glioma U-373 cells. Results showed that except for nuclear localization, there were no specific cytoplasmic organelles that PKC-alpha or -beta transl...
Studies show that kidneys produce 2',3'-cAMP, 2',3'-cAMP is exported and metabolized to 2'-AMP and 3'-AMP, 2'-AMP and 3'-AMP are metabolized to adenosine, 2',3'-cAMP inhibits proliferation of preglomerular vascular smooth muscle cells (PGVSMCs) and glomerular mesangial cells (GMCs), and A(2B) (not A(1), A(2A), or A(3)) adenosine receptors mediate part of the antiproliferative effects of 2',3'-c...
RATIONALE Accumulating studies suggest that nitric oxide (NO) deficiency and oxidative stress are central pathological mechanisms in type 2 diabetes (T2D). Recent findings demonstrate therapeutic effects by boosting the nitrate-nitrite-NO pathway, which is an alternative pathway for NO formation. This study aimed at investigating the acute effects of inorganic nitrate on glucose and insulin sig...
The insulin-like growth factor (IGF) family is essential for normal embryonic growth and development and it is highly conserved through vertebrate evolution. However, the roles that the individual members of the IGF family play in embryonic development have not been fully elucidated. This study focuses on the role of IGF-2 in zebrafish embryonic development. Two igf-2 genes, igf-2a and igf-2b, ...
The 5-hydroxytryptamine 2C (5-HT(2C)) receptor subtype has received considerable attention as a target for drug discovery, having been implicated in a wide variety of disorders. Here, we describe the in vitro pharmacological profile of the novel 5-HT(2C) receptor-selective agonist vabicaserin [(-)-4,5,6,7,9,9a,10,11,12,12a-decahydrocyclopenta[c] [1,4]diazepino[6,7,1-ij]quinoline hydrochloride] ...
We have recently identified the first human lysine (K) acetyltransferase 2A and 2B (called KAT2A/2B; known also as GCN5/PCAF, respectively)-dependent acetylome and revealed a mechanism by which KAT2A/2B-mediated acetylation of serine/threonine polo-like kinase 4 (PLK4) maintains correct centrosome number in human cells, therefore contributing to the maintenance of genome stability.1.
