Molecular Opioid Manipulations and Ingestive Behavior<\/h4>\n

The pharmacological, biochemical and behavioral characterization of endogenous opioid receptor subtypes was followed by the identification and cloning of the major opioid receptor genes, mu (MOP), kappa (KOP) and delta (DOP), as well as the identification of the orphan opioid receptor (NOP). These findings led to the development of two major molecular techniques to study the role of these genes in behavioral processes: a) the knockout approach wherein a particular gene is deleted in development and the consequences studied, and b) the knockdown approach in which portions of a particular gene are temporarily inactivated. In a long-term collaboration with Drs. Gavril Pasternak, YX Pan and Grace Rossi, our laboratory has been able to administer central employ antisense oligodeoxynucleotides (AS ODN) probes developed as 15-22 cDNA nucleotide bases to inactivate mRNA sequences of particular exons of the MOP, KOP, DOP and NOP opioid receptor genes. Our studies examined the molecular pharmacology of feeding elicited by opioid peptides (dynorphin, beta-endorphin), opioid receptor agonists (morphine, DAMGO, morphine-6B-glucuronide) and environmental situations (ad libitum feeding and body weight, food deprivation, glucoprivation, lipoprivation).<\/p>\n
