Glioblastoma is the most lethal tumor of the central nervous system, presenting a very poor prognostic, with a survival around 16 months. The interaction of mesenchymal stem cells and tumor cells has been studied, showing a bias in their role favoring or going against aggressiveness. Natural products such as flavonoids have showed their anticancer properties and the synergic potential with the activation...
Monocrotaline (MCT) and its pyrrole derivative, dehydromonocrotaline (DHMC), interact with molecular targets in cells of the central nervous system. DHMC presents higher toxicity than MCT indicating that its metabolism of MCT is a critical step of this alkaloid toxicity. This study sought to elucidate the metabolism and the toxicity of MCT in C6 astrocyte cell line and primary cultures of rat astrocytes...
Studies have shown cases of poisoning with plants from the genus Crotalaria (Leguminosae) mainly in animals. They induce damages in the central nervous system (CNS), which has been attributed to toxic effects of the pyrrolizidine alkaloid (PA) monocrotaline (MCT). Previously we demonstrated that both MCT and dehydromonocrotaline (DHMC), its main active metabolite, induce changes in the levels and...
