“…For example, anticancer activity of the naphthoquinone derivative plumbagin seems to result from ROS formation upstream of cell death-associated pathways, including inhibition of topoisomerase II followed by DNA strand breaks and induction of apoptosis (187). Similarly, shikonin, another naphthoquinone natural product, induces apoptogenic oxidative stress in human hepatoma cells; ROS-dependent activation of the stress-related JNK pathway and subsequent …”

“…actualmente se sabe que las plantas producen activamente ros como moléculas señali-zadoras de diferentes vías y procesos metabólicos, controlando actividades normales del crecimiento y desarrollo de la planta; germinación, mitosis, elongación celular, senescencia, muerte celular, lignificación de tejidos, formación de elementos cribosos del floema y xilema, regulación de la expresión génica asociada a estrés biótico y abiótico, sistema de defensa contra patógenos, etc. (Bray et al 2000, apel e Hirt 2004, mittler et al 2004, Kawiak et al 2007, marczak et al 2008, shao et al 2008 Por otro lado, investigaciones realizadas en cultivo in vitro asocian efectos benéficos en el desarrollo de los explantes con la presencia de algunas formas de ros. en estos trabajos se describe cómo la adición intencional al medio de cultivo de algún agente reductor u oxidante puede estimular un tipo de respuesta particularmente benéfica.…”

“…They suggested that apoptosis in this cell line was signaled by the reactive oxygen species (ROS) pathway. Prior to this, it was shown that inhibitors of topoisomerases induced ROS apoptotic pathway (Kawiak et al, 2007;Mend and Ding, 2007). It is highly possible that the inhibitory activity of benzothiazoles on topoisomerase IIa also triggers ROS-mediated apoptosis.…”
