Hydrogen sulfide (H(2)S), a gasotransmitter, exerts both neurotoxicity and neuroprotection, and targets multiple molecules including NMDA receptors, T-type calcium channels and NO synthase (NOS) that might affect neuronal viability. Here, we determined and characterized effects of NaHS, an H(2)S donor, on cell viability in the primary cultures of mouse(More)
Anti-HLA antibodies reportedly exist in 31% of pregnant women. However, few ocurrences of neonatal alloimmune thrombocytopenia (NAIT) caused by anti-HLA antibody have been reported. In this study, maternal anti-HLA B60 and B61 antibodies were identified in patient serum at birth, but no anti-platelet antibodies were present. No maternal anti-HLA A2, A24,(More)
In order to corroborate the regulatory role of Ca++-calmodulin system in the steroidogenic response to adrenocorticotropic hormone (ACTH), the effects of calmodulin inhibitors (chlorpromazine, trifluoperazine, and W-7) on cortisol production and cellular cholesterol ester hydrolysis induced by ACTH in bovine adrenocortical cells were examined. Three(More)
In order to elucidate the relationship between cyclic AMP and the Ca2+-calmodulin system in the steroidogenic response to adrenocorticotropic hormone (ACTH), the effects of calmodulin inhibitors (trifluoperazine and W-7) on cortisol production and cellular cholesterol ester hydrolysis induced by ACTH or dibutyryl cyclic AMP in bovine adrenocortical cells(More)
A new HLA-B*78 allele, B*7805, was identified in a healthy Japanese female. The results of her serological HLA class I typing showed an unusual Bw4/Bw6 pattern with strongly positive reactivity to anti-Bw6, i.e. A24, -, B52, -, Bw4, Bw6. In DNA typing, she was typed as A*24, -, B*52, B*78-like, Cw1202, -, (Bw4, Bw6). Cloning and sequencing of exon 2 and(More)
Intracellular sources of extramitochondrial corticoidogenic cholesterol in bovine, rat and hamster adrenocortical cells were examined in vitro by comparing the species differences in the effects of various inhibitors on the adrenocorticotropic hormone (ACTH)-induced corticoidogenesis. The inhibitors were ML-236B (3-hydroxy-3-methylglutaryl coenzyme A(More)
Hydrogen sulfide (H2S), the third gasotransmitter, is endogenously generated by certain H2S synthesizing enzymes, including cystathionine-γ-lyase (CSE) and cystathionine-β-synthase (CBS) from L-cysteine in the mammalian body. Several studies have shown that endogenous and exogenous H2S affects the proliferation of cancer cells, although the effects of H2S(More)
