Leptin, a hormone secreted from white adipose tissue, has been shown to normalize the body weight of ob/ob but not db/db mice as postulated by Coleman in his classical parabiosis experiments. The major effect of leptin is therefore to decrease food intake, thus resulting in a breakdown of fat stores. Recently, we have suggested that leptin plays a role in(More)
Numerous studies have revealed an association between nutritional status, adiposity, and reproductive maturity. The role of leptin, a hormone secreted from adipose tissue, in the onset of reproductive function was investigated. Normal prepubertal female mice injected with leptin grew at a slower rate than controls as a result of the hormone's thinning(More)
The development of gene transfection technologies has greatly advanced our understanding of life sciences. While use of viral vectors has clear efficacy, it requires specific expertise and biological containment conditions. Electroporation has become an effective and commonly used method for introducing DNA into neurons and in intact brain tissue. The(More)
Sensitivity to leptin is associated with a normal regulation of the adipose mass, whereas decreased leptin sensitivity results in elevated adipose tissue stores. To address whether the effects of chronic hyperleptinemia are sustained with age, we generated transgenic mice that overexpress leptin under the control of the fat specific aP2 promoter/enhancer.(More)
The roles of sulfhydryl and disulfide groups in the specific binding of synthetic cannabinoid CP-55,940 to the cannabinoid receptor in membrane preparations from the rat cerebral cortex have been examined. Various sulfhydryl blocking reagents including p-chloromercuribenzoic acid (p-CMB), N-ethylmaleimide (NEM), o-iodosobenzoic acid (o-ISB), and methyl(More)
This study examined the isolation and differentiation of dorsal root ganglion progenitor cells for therapeutic use in neurodegenerative diseases. Rat embryonic dorsal root ganglia progenitors were isolated and purified using the differential adhesion method combined with cytosine arabinoside treatment. After culture in serum-free medium supplemented with(More)
