Cart (cocaine- and amphetamine-regulated transcript) was first identified to be a major brain mRNA up-regulated by cocaine and amphetamine. The CART protein has been established as a satiety factor closely associated with the action of leptin. To assess CART's role as an anorexigenic signal, we have generated CART-deficient mice by gene targeting. On a high(More)
In this study, we attempted to identify the mechanisms of paeoniflorin on antinociceptive effects in mice. Paeoniflorin (48, 96, 240, 480 microg, i.c.v.) showed dose-related antinociception both on the early and late phases of formalin test in mice. Moreover, paeoniflorin (48 microg, i.c.v.) could potentiate the antinociception of morphrine (0.5, 1.0 mg/kg,(More)
Transplantation of neural stem/progenitor cells (NSPCs) is a promising strategy for repair of the diseased/injured central nervous system (CNS); however, controlling their differentiation remains a significant hurdle. This study is aimed at controlling differentiation and specifically at screening exogenous factors to direct NSPC differentiation into(More)
Leptin is a hormone synthesized and secreted from adipose tissue. To study the physiologic effects of chronic leptin treatment, normal adult female Sprague-Dawley rats were injected subcutaneously for 35 days. Twice daily injections (250 microgram/day, b.i.d.) resulted in a significant (P<0.05) decrease in food intake that was maintained for 10 days before(More)
Direct prolactin (PRL) effects on dopamine (DA) release from fragments of rat striatal tissues were studied by the in vitro superfusion technique. The DA collected in the superfusates was quantified by a radio-enzymatic assay. In the present experiments, intact and one-week gonadectomized adult male and female rats were used. The spontaneous release of DA(More)
