Resumen

O câncer constitui um amplo problema para a sociedade, sua ocorrência está associada ao envelhecimento da população, bem como ao aumento da prevalência de fatores de risco. O câncer cervical é o terceiro tipo de tumor mais frequente na população feminina, sendo a quarta causa morte de mulheres por câncer no Brasil. Cerca de 60% dos antineoplásicos atualmente utilizados foram descobertos a partir de produtos naturais, sabe-se que o Euterpe oleracea Mart. conhecido popularmente como açaí, tem sido objeto de muitos estudos nos últimos anos, devido ao seu alto consumo e à sua grande quantidade de fitoquímicos, principalmente à alta taxa de polifenóis que apresentam efeitos antiproliferativos, pró-apoptóticos em células tumorais, supressão de tumores, prevenção de adipogênese, estresse oxidativo e alta atividade anti-inflamatória. Este estudo teve como objetivo avaliar a atividade antitumoral do fruto, a partir do extrato hidroalcoólico do mesmo, combinado ou não ao quimioterápico 5-Fluorouracil. As células HeLa foram cultivadas em incubadora de CO2 e tratadas com diferentes concentrações do extrato (0.01-1000 μg/mL). A citotoxicidade do mesmo foi avaliada pelo ensaio de viabilidade celular utilizando brometo de 3-(4,5-dimetiltiazol-2-il)-2,5-difenil-tetrazólio e a avaliação do metabolismo celular foi realizada pela taxa total de produção de óxido nítrico. Os resultados mostraram um potencial para a redução da proliferação celular, especialmente na concentração de 1 μg/mL, e para o metabolismo celular, as células apresentaram taxas semelhantes às do controle negativo nas concentrações mais baixas.

Michele Rorato Sagrillo, Universidade Franciscana

He has a degree in Biological Sciences from the Federal University of Santa Maria (2000) and a Master's degree in Sciences - Genetics, from the Federal University of São Paulo - Escola Paulista de Medicina, UNIFESP. PhD in Pharmacology - Pharmacogenomics area, from the Postgraduate Program in Pharmacology at the Federal University of Santa Maria- RS. Adjunct Professor II at the Franciscan University (UFN), responsible for the disciplines of Medical, Human and Molecular Genetics. As a teacher and advisor in the Postgraduate Program in Nanosciences at UFN, she has the opportunity to contribute to the training of researchers and the development of knowledge in the area. Her experience encompasses safety and therapeutic efficacy trials in different contexts, such as in silico, in vitro and in vivo, including the use of alternative models. These tests are conducted on both bioactive substances in their free and nanostructured forms, exploring the therapeutic potential of nanotechnologies. Currently, its main line of research focuses on the use of natural resources and industrial waste from the central region of Rio Grande do Sul. This approach aims to develop new products that can add value to these resources, offering a sustainable alternative for their use. The use of natural resources and industrial waste can provide the discovery of new bioactive compounds, as well as contribute to the circular economy, reducing waste and promoting the conscious use of available resources. This line of research seeks to boost innovation, exploring the potential of these resources for the development of products with therapeutic, cosmetic or pharmaceutical applications. By taking advantage of local resources, we are promoting regional development and sustainability, while contributing to scientific and technological advancement in the area of ​​nanosciences.
