El Inhibidor de carboxipeptidasa de patata (PCI): un antagonista del EGF con actividad antitumoral

Blanco Aparicio, Carmen 17 July 1998 (has links)
In this work we report that potato carboxypeptidase inhibitor suppresses the growth of several human and mouse pancreatic adenocarcinoma cell lines. The inhibitor also reduces the growth of solid tumors obtained by subcutaneous injection of human adenocarcinoma cell line in nude mice and the appearance of metastasis in mice injected intraesplenically with B16H10 melanoma cells. A transgenic line has been characterized, mice develop choroid plexus carcicomas and insulinomas. Lifespan of animals immunized with PCI I s significantly higher than control mice. To further characterize the effects of PCI on tumor cell growth, analyses of cell cycle phase distribution have been performed. A significant increase in the G0/G1 phase is also detected. This finding is correlated with an increase in the mRNA expression of p53. Moreover, we have demonstrated that PCI is easily internalized by the cells and the inhibitor remain altered after the internalization / En el presente trabajo se ha demostrado que el inhibidor de carboxipeptidasa de patata (PCI) tiene un efecto inhibitorio sobre el crecimiento tumoral tanto in vitro como in vivo, y se ha estudiado su mecanismo de acción, lo que ha llevado a descubrir que el PCI es un antagonista del EGF. Con dicho fin se han utilizado técnicas de cultivo celular en conjunción con técnicas bioquímicas, de biología molecular, de análisis computacional y ensayos con modelos animales / En el present treball s’ha demostrat que l’inhibidor de carboxipeptidasa de patata (PCI) té un efecte inhibitori sobre el creixement tumoral tant in vitro com in vivo i s’ha estudiat el seu mecanisme d’acció, que ha permès descobrir que el PCI és un antagonista de l’EGF. Amb aquest fi s’han utilitzat tècniques de cultiu cel·lular amb tècniques bioquímiques, de biologia molecular, d’anàlisi computacional i assajos amb models animals
