Alpha tocopheryl succinate treatment (6-8 micrograms/ml), which inhibited the growth of murine neuroblastoma (NBP2) cells (46 +/? 3%), reduced basal and prostaglandin (PG)E1- and PGA2-stimulated adenylate cyclase (AC) activity in vitro. It also inhibited sodium fluoride (NaF)- and forskolin-stimulated AC activity, suggesting that the effect of vitamin E succinate on AC activity is mediated via stimulatory GTP-binding protein (Gs) and catalytic subunit. Vitamin E succinate-induced reduction of AC activity is not strictly related to inhibition of cell growth. This is substantiated by the finding that, although retinoic acid and butylated hydroxyanisole reduced the growth by over 50%, they did not inhibit AC activity. On the other hand, 4-(3-butoxy-4-methoxybenzyl)-2-imidazolidinone (R020-1724, 200 micrograms/ml), which inhibited growth (73 +/? 3%) and induced differentiation in NB cells, increased basal and PGE1-stimulated AC activity. Vitamin E succinate treatment also reduced PGE1- and PGA2-AC activity in murine fibroblasts (L-cells) without inhibiting growth. 相似文献

Microparticles (MPs) resulting from vesiculation of different cell types in Plasmodium falciparum infection correlate with the level of proinflammatory cytokine TNF that may thereby determine the disease severity. Using TruCount tube based flow cytometric method for the exact quantification of MP and enzyme linked immunosorbent assay for the measurement of TNF, we conducted a hospital based case control study on P. falciparum malaria patients to scrutinize and infer the link between the two. In 52 cerebral malaria (CM), 21 multi-organ-dysfunction (MOD), 12 non cerebral severe malaria (NCSM) and 43 uncomplicated malaria patients, the MP level was found to be significantly elevated in febrile malaria patients compared to healthy controls and a striking decrease in MP level was observed with the clearance of the P. falciparum infection in the patients upon follow-up. The lowering of the parasite density with the level of plasma TNF and the positive correlation of the cytokine with the cell derived MPs and negative correlation with the respective cell count in human malaria patients suggests that TNF may be a key stimulant to the cells resulting in the release of MPs in malaria infection. 相似文献
