Abstract

Un clone d'ADNc codant pour la prohormone convertase humaine PC5 a été isolé de l'ARN messager des surrénales humaines. La séquence protéique qui en a été déduite devrait coder pour une préprotéine PC5 de 915 acides aminés, ayant un degré très élevé d'homologie avec ses homologues du rat et de la souris précédemment codées. L'ARNm de la PC5 est détecté dans de multiples tissus humains, notamment le cerveau, les surrénales, la thyroïde, le coeur, le placenta, les poumons et les testicules. Il n'était pas détectable dans le foie et il est présent à des taux inférieurs dans les muscles squelettiques, les reins, le pancréas, l'intestin grêle et l'estomac. La co-transfection des vecteurs d'expression de la PC5 humaine et de la prorénine humaine dans des cellules GH4C1 cultivées provoque la sécrétion de rénine active. L'activation de la prorénine humaine par la PC5, qui dépend d'une paire d'acides aminés basiques aux positions 42 et 43 du prosegment de la prorénine, n'a lieu que dans des cellules contenant des granules sécrétoires à coeur dense. La PC5 humaine a été colocalisée par immunochimie avec la rénine dans la zone glomérulée des surrénales, ce qui suggère qu'elle pourrait participer à l'activation d'un système rénine-angiotensine local dans le cortex surrénal humain. La PC5 est surexprimée dans les coronaires athéroscléreuses. L'atténuation de l'expression de la PC5 par un oligonucléotide antisens spécifique a inhibé efficacement la prolifération des cellules des muscles lisses en culture. En outre, l'antisens a inhibé la sténose de la carotide dans un modèle de lésion de la carotide. Ces résultats indiquent que l'atténuation de la PC5 s'applique à la prévention de la resténose. Les PC pourraient être des cibles de choix pour le traitement de toutes les maladies prolifératives mettant en jeu leur action sur un facteur de croissance donné. Enfin, l'oligonucléotide antisens de la PC5 est à utiliser pour atténuer l'activité de cette enzyme envers la gp160 du VIH, puisqu'ils coexistent dans les lymphocytes T CD4+ et que la glycoprotéine virale peut être clivée par la PC5.
