FDA Approves Two New Parkinson's Drugs 
Good news for the Parkinson's community came in early January this year as the FDA approved two new drugs. RYTARY™ is an extended-release oral 
capsule form of carbidopa/levidopa for use in early through late stages of Parkinson's disease (PD). DUOPA™ is approved for treatment of motor 
fluctuations in the late stages of PD. It is administered through an infusion pump that delivers carbidopa and levodopa directly into the small intestine. 
• RYTARY™ (pronounced rye-TAR-ee) addresses the needs of patients who 
experience reduced mobility as levodopa levels drop by providing a formulation of carbidopa/levidopa that releases more slowly over time. In addition to the 
extended-release beads, the capsule contains immediate release beads that are 
designed for rapid effectiveness. Studies of RYTARY showed subjects had significantly increased amount of "on" time during waking hours without 
troublesome dyskinesia. The manufacturer states that dosage of RYTARY will 
require careful monitoring, as there is not a direct 1:1 correlation between it and

Atef ME, Anand-Srivastava MB, Université de Montréal, Dép. de physiologie, Pavil on Paul-G.-Desmarais, 2960, chemin de la Tour, Montréal (Qc) H3T 1J4.  Studies on the protein expression of Gqα and PLCβ1 in vascular smooth muscle cel s (VSMCs) from spontaneously hypertensive rats (SHR) at different ages are lacking, and the implication of Gqα in the hypertrophy of VSMCs still not clearly defined. Here we investigated if VSMCs from SHR, at different ages (12 and 16 weeks), exhibit enhanced expression of Gq/11α and PLCβ1 and if this up-regulation is related to VSMCs hypertrophy (increased protein synthesis). Since the levels of endogenous angiotensin II (ANG-II) and endothelin-1 (ET-1) are enhanced in VSMCs from SHR, the aim of this study was also to characterize the signaling mechanisms whereby endogenous ANG II and ET-1 can modulate Gqα -PLCβ1 expression in VSMCs. We report for the first time that VSMCs from 16 weeks but not from 12 weeks SHR exhibited enhanced levels of Gqα and PLCβ1 proteins as compared to VSMCs from age matched WKY rats. The increased level of Gqα and PL Cβ1 proteins in VSMCs form SHR was associated with enhanced protein synthesis (cell hypertrophy). Silencing of Gqα protein by specific SiRNA and AS-ODN attenuated the enhanced protein synthesis in VSMCs from SHR. The enhanced expression of Gqα and PLCβ1 proteins in VSMCs from 16-wk-old SHR was inhibited by AT1 and ETA receptor antagonists, losartan and BQ123 respectively but not by ETB receptor antagonist, BQ788. In addition, losartan and BQ123 also attenuated the enhanced protein synthesis in VSMCs from SHR compared to WKY. Furthermore, the augmented phosphorylation of ERK1/2 and PKC delta in VSMCs from SHR was attenuated by losartan and BQ123 but not by BQ788. These results suggest that the enhanced levels of endogenous ANGII and ET-1 in VSMCs from SHR increase the protein expression of Gqα and PLCβ1 and subsequent VSMCs hypertrophy. Which may implicate MAP kinase signaling and PKC delta activation. P2 - BAGHERI, Haniyeh  Régulation différentielle de différents ligands sur la désensibilisation du récepteur opioide delta. Haniyeh Bagheri, Graciely Pineyro, Université de Montréal, Centre de recherche du CHU Sainte-Justine, Montréal (Qc). Introduction : Les opiacés sont des analgésiques très efficaces pour le traitement des douleurs, mais leur administration prolongé peut induire de la tolérance analgésique. Au niveau moléculaire, la tolérance serait associée à la désensibilisation des récepteurs opiacés. La morphine, agoniste du récepteur Mu, produit le plus de tolérance avec une faible capacité d'internalisation et une grande capacité de désensibilisation. Ces observations mettent en évidence que la conformation spécifique de la morphine détermine ces phénomènes. Nous estimons que les conformations distinctes stabilisées par les ligands opioïdes semblent être responsables des différents profils de désensibilisation et d'internalisation. Résultats : En ce qui concerne la désensibilisation du RDO, nous avons observé que la réponse aux agonistes tels que le mcpTIPP, la morphine et le SB 235863 désensibilisent plus lentement que cel le du DPDPE qui est similaire au snc-80. D'autres agonistes tels que la deltorphine et la met-enképhaline qui ne se différencient pas entres eux, ont une plus grande capacité de désensibilisation que le DPDPE et le snc-80. Quant à leur capacité d'internalisation, le mcpTIPP et le SB 235863 n'induisent aucune internalisation du RDO. Alors, que la deltorphine engendre 80 % d'internalisation du RDO. Les agoniste DPDPE, le snc-80 et la met-enkephaline induisent ± 60 % d'internalisation du RDO. Finalement, les ligands opiacés tels que la deltorphine, la met-enképhaline, le snc-80 et le DPDPE sont le plus efficace à inhiber l'AMPc, contrairement au mcpTIPP et au SB 235863. Conclusion : Ces résultats nous indiquent qu'ils n'existent aucune corrélation entre l'internalisation et la désensibilisation du RDO. Ce manque de corrélation est caractéristique de la stabilisation de différentes conformations du récepteur activé par des ligands distincts.
