En este contexto, la producción biotecnológica del potente agente anticancerígeno paclitaxel podría incrementarse utilizando cultivos celulares de Taxus spp. en condiciones in vitro. El objetivo de este trabajo ha sido proporcionar nuevos conocimientos sobre la biosíntesis y la producción de paclitaxel para la optimización de las biofactorías de Taxus spp. Nuestros resultados mostraron que: (1) La acción sinérgica de coronatina y calix[8]areno incrementa significativamente la síntesis de paclitaxel.

The emergency to obtain effective substances against cancer, and the awareness to protect natural resources make plant biofactories a promising alternative for obtaining plant-derived compounds. In this context, the biotechnological production of the potent anticancer agent paclitaxel could be increased using in vitro cell cultures of Taxus spp. The objective of this work was to provide novel knowledge related to the biosynthesis and production of paclitaxel through the implementation of optimized Taxus spp. biofactories. Our results showed that: (1) The synergistic action of coronatine and calix[8]arene significantly increases the paclitaxel synthesis. (2) There exists an epigenetic control over the paclitaxel biosynthesis pathway, adversely affected in cultures maintained long-term under in vitro conditions. (3) By increasing the level of ploidy in Taxus spp. cell cultures, the production of taxanes also increased. (4) The enzyme TB574 is the ideal candidate to carry out the hydroxylation step on the C1 carbon of the taxane skeleton. |
