Aberrant promoter hypermethylation of tumor suppressor genes is proposed to be a common feature of primary cancer cells. We recently developed a pharmacological unmasking microarray approach to screen unknown tumor suppressor gene candidates epigenetically silenced in human cancers. In this study, we applied this method to identify such genes in head and neck squamous cell carcinoma (HNSCC). We...
The mechanisms by which clock neurons in the Drosophila brain confer an ∼24-hr rhythm onto locomotor activity are unclear, but involve the neuropeptide diuretic hormone 44 (DH44), an ortholog of corticotropin-releasing factor. Here we identified DH44 receptor 1 as the relevant receptor for rest:activity rhythms and mapped its site of action to hugin-expressing neurons in the subesophageal zone ...
The effects of a single injection of haloperidol (2.0 mg/kg), a typical antipsychotic drug, on neurotensin (NT) concentrations and NT/neuromedin N (NT/NN) mRNA expression in adult female and male rats were examined. There were significant estrous cycle stage-related differences in both NT concentrations and NT/NN mRNA expression in female control rats. Although acute administration of haloperid...
The type of food source has previously been shown to be as important as the level of food intake in influencing lifespan. Here we report that different Escherichia coli food sources alter Caenorhabditis elegans lifespan. These effects are modulated by different subsets of sensory neurons, which act with nmur-1, a homolog of mammalian neuromedin U receptors. Wild-type nmur-1, which is expressed ...
The existence of SP was described in the 1930s by Von Euler and Gaddum in mammals, and tachykinin peptides were identified and sequenced by Erspamer in non-vertebrated (eledoisin) and then in nonmammalian species (physalaemin). In the 1960s Lembeck continued Von Euler and Gaddum’s studies, describing the effects of SP and other tachykinins in the central nervous system (CNS) and peripheral prep...
Neuromedin U (NMU) is a highly conserved neuropeptide with a variety of physiological functions mediated by two receptors, peripheral NMUR1 and central nervous system NMUR2. Here we report the generation and phenotypic characterization of mice deficient in the central nervous system receptor NMUR2. We show that behavioral effects, such as suppression of food intake, enhanced pain response, and ...
