RESUMO
Several plants of the genus Tragia L. have shown antibacterial, fungicidal, and antiproliferative activity, among other types of activities; however, most species of the genus have not been investigated. Tragia volubilis L. is native to tropical America and Africa, and although it has been reported as medicinal in the literature, it has not been thoroughly investigated. In this study, the phytochemical screening, isolation, and identification of compounds and the determination of the antioxidant activity of the aqueous extract of Tragia volubilis L. and its partitions were carried out. Ethyl acetate and n-butanol partitions of the extract present high antioxidant activity according to the Antioxidant Activity Index. Due to their activity, these partitions were tested on RKO cells as a representative model, both individually and in combination with Doxorubicin. It was found that the partitions significantly reduced the effect of Doxorubicin, as well as the expression of proteins involved in DNA damage and cell death. While the reduction of the chemotherapeutic effect of Doxorubicin on tumor cells may not be a desired outcome in therapeutic settings, the findings of the study are valuable in revealing the antioxidant potential of Tragia volubilis L. and its partitions. This highlights the importance of carefully regulating the application of antioxidants, especially in the context of cancer chemotherapy.
RESUMO
Los largometrajes han sido utilizados como una herramienta de aprendizaje llamativa en el campo de la salud, esto debido a que ciertas enfermedades que suelen ser raras dentro de la población se prestan para desarrollar una historia en base a las mismas. La Osteogénesis imperfecta conocida también como la enfermedad de los huesos de cristal, es un trastorno genético bastante diverso, si bien el 90 % de los casos se presentan con mutaciones de herencia de tipo autosómicas dominantes, un 10 % restante corresponde a mutaciones autosómicas recesivas o de causa desconocida. En el presente trabajo hemos generado una recopilación de aspectos relevantes sobre esta enfermedad correlacionando con la trama de dos trabajos cinematográficos, Frágiles y El protegido; esto con el fin de analizarlo como una posible herramienta para el aprendizaje de esta enfermedad y de otras patologías de carácter genético.

Feature films have been used as a striking learning tool in the field of health, this because certain diseases that are usually rare within the population lend themselves to developing a story based on them. Imperfect Osteogenesis also known as crystal bone disease, is a fairly diverse genetic disorder, although 90 % of cases present with autosomal dominant inherited mutations, the remaining 10 % corresponds to autosomal recessive mutations or of unknown cause. In the present work we have generated a compilation of relevant aspects about this disease correlating with the plot of two cinematographic works, Fragile and The Protected; this in order to analyze it as a possible tool for learning about this disease and other pathologies of a genetic nature.
