A radiation hybrid (RH)-derived physical map of 25 markers on the feline X chromosome (including 19 Type I coding loci and 6 Type II microsatellite markers) was compared to homologous marker order on the human and mouse X chromosome maps. Complete conservation of synteny and marker order was observed between feline and human X chromosomes, whereas the same markers identified a minimum of seven rearranged syntenic segments between mouse and cat/human X chromosome marker order. Within the blocks, the feline, human, and mouse marker order was strongly conserved. Similarly, Y chromosome locus order was remarkably conserved between cat and human …

The Roles Of Several Kinases In Mice Tolerant To Delta-9-Tetrahydrocannabinol, Matthew C. Lee Jan 1999

The Roles Of Several Kinases In Mice Tolerant To Delta-9-Tetrahydrocannabinol, Matthew C. Lee

Theses and Dissertations

It has been suggested that the CB1 G-protein-coupled receptor is internalized following agonist binding and activation of the second messenger pathways. The process of desensitization and resensitization is intimately involved with receptor internalization. Phosphorylation alters tolerance to cannabinoids thus contributing to tolerance. It is proposed that phosphorylation enhances the down-regulation of the CB1 receptor. These findings led us to look at which kinase(s) may be involved in cannabinoid tolerance. We therefore hypothesize that by preventing phosphorylation of the CB1 receptor, we may reverse tolerance. We evaluated our hypothesis by testing the role of several kinases in tolerance: protein kinase A …
