Abstract

Heat Chock Protein 90 (Hsp9O) is a molecular chaperone necessary for the stability and for the function of a large number of proteins which are playing an important role in different signaling pathways. It is also necessary for mutated, chimeric and/or overexpressed proteins allowing growth and survival to cancer cells. Structural and biochemical tests revealed that Hsp9O is at the center of a machinery complex undergoing conformational changes driven by an ATPase. Furthermore, there are a lot of interactions between Hsp9O and a set of protein called co-chaperones. These interactions are essentials because they allow Hsp9O to perform his role of molecular chaperone correctly. Hsp9O inhibitors are unique because they inhibit a large number of signaling pathways even if they have a specific molecular target. The inhibition of Hsp9O leads to the simultaneous degradation of these client proteins by a ubiquitin-dependent proteasome pathway. By inhibiting Hsp9O, essentials signaling pathways for growth and survival of cancer cells are inhibited, and it leads to the death of these cells. An interesting point is that the association of Hsp9O inhibitors with a classical antitumoral agent may highly increase the efficiency of the classical agent. Hsp9O exists as a dimer, composed of three domains. Two of them are targeted by different inhibitors. Currently, they are numerous inhibitors acting on the N-terminal domain, including the ansamycin family. A lot of them are now in phases I, II and III of clinical trials and they are tested against a large panel of cancers. Other inhibitors are able to bind the C-terminal domain. In this work, I’ll review the actual knowledge about Hsp9O and the different ways to act on this protein to develop new cancer therapies La Heat Shock Protein 90 (Hsp9O) est une chaperonne moléculaire nécessaire à la stabilité et à la fonction d’un grand nombre de protéines utilisées dans les voies de signalisation cellulaire ainsi qu’aux multiples protéines de signalisation mutées, chimériques et/ou surexprimées qui permettent la croissance et la survie des cellules cancéreuses. Des analyses biochimiques et structurelles ont révélé qu’Hsp90 était au centre d’un complexe mécanistique avec changements conformationnels couplés à une ATPase. De plus, de nombreuses interactions avec un ensemble de protéines appelées co-chaperonnes sont nécessaires au bon fonctionnement d’Hsp9O car ces protéines l’aident à accomplir son rôle de chaperonne moléculaire. Les inhibiteurs d’Hsp9O sont uniques dans le sens où, malgré qu’ils soient dirigés vers une cible moléculaire spécifique, ils permettent d’inhiber de multiples voies de signalisation cellulaire. En fait, l’inhibition d’Hsp9O l’empêche de réaliser sa fonction et dès lors, les protéines-clientes en dépendant sont amenées à être dégradées par le protéasome. En inhibant les points cruciaux des multiples voies utilisées par les cellules cancéreuses pour leur développement et leur survie, on induit la mort de ces dernières. De plus, l’association d’un inhibiteur d’Hsp9O avec un agent anti-tumoral classique peut augmenter drastiquement l’efficacité de l’agent classique. L’Hsp9O existe sous forme d’un homodimère, contenant trois domaines. Deux de ces trois domaines sont ciblés par les inhibiteurs. Il existe actuellement de nombreux inhibiteurs agissant au niveau du domaine N-terminal, notamment ceux de la famille des ansamycines. Beaucoup d’entres eux sont à présent entrés dans les diverses phases des essais cliniques et ce contre de nombreux types de cancers. D’autres inhibiteurs peuvent quant à eux, agir au niveau du domaine C-terminal. Il est question dans ce travail de faire le point sur les connaissances actuelles à propos de l’Hsp9O ainsi que sur les différentes manières d’agir sur cette protéine en vue de développer de nouveaux traitements anticancéreux.

Abstract

Heat shock proteins (HSPs) were discovered as polypeptides induced by stress that can be found in all kingdoms of cellular organisms. Their functions were, a first enigmatic and these proteins were thus classified by molecular weight, as in—Hsp27, Hsp70, Hsp90, Hsp110. More recently, each of these size-classified molecules has attributed a role in protein folding, and they thus came to be known, as a class, as molecular chaperones. However, the they possess properties beyond chaperoning. Indeed, their discovery in the extracellular spaces suggested roles in regulation of the immune responses.
