Abstract: Les tumeurs attirent des vaisseaux sanguins pour croître au moyen d'un processus appelé angiogenèse. La quantité relative de stimulants et d'inhibiteurs est un facteur déterminant dans le début de l'angiogenèse. Les thrombospondines 1 et 2 sont des glycoprotéines adhésives ayant la capacité d'inhiber l'angiogenèse. On a mappé l'activité inhibitrice en rapport avec les répétitions de type 1 de TSP-1 et de TSP-2. L'invention concerne des protéines chimères qui contiennent des parties anti-angiogéniques de TSP-1, de TSP-2, d'endostatine, d'angiostatine, du facteur plaquettaire 4 ou prolactine, qui sont liés à une partie de la région N-terminale de la protéine humaine de matrice oligomère de cartilage (COMP) qui permet la formation de pentamères. L'invention concerne aussi des molécules d'acides nucléiques, des vecteurs et des cellules hôtes qui sont destinés à l'expression et à la production de ces protéines chimères. Dans d'autres modes de réalisation, l'invention concerne des procédés pour traiter des humains ou d'autres mammifères avec des protéines anti-angiogéniques afin de réduire la taille ou la vitesse de croissance des tumeurs. Les régions de répétition de type 1 de TSP-1 et de TSP-2 seraient des inhibiteurs de l'infection par le VIH, c'est pourquoi les protéines chimères contenant ces répétitions peuvent également être utilisées à cette fin-là ainsi que pour inhiber l'angiogenèse.
