    Analysis of the combined effects of resveratrol and radiation on lung cancer cells
    2017 - MORENO, CAROLINA S.; ROGERO, SIZUE O.; GALISTEO JUNIOR, ANDRES J.; VIEIRA, DANIEL P.; CRUZ, AUREA S.; SAKURABA, ROBERTO K.; WELTMAN, EDUARDO; ROGERO, JOSE R.
    Mucoepidermoid lung carcinoma is frequently manifested by obstructive trachea symptoms. It is necessary to develop effective curative or palliative therapeutic strategies for treating mucoepidermoid lung carcinoma through administration of compounds that improve ionizing radiation treatment, thereby increasing the effects of the treatment on tumor cells while minimizing the effects on normal tissues surrounding the tumor cells. Resveratrol is a polyphenolic phytoalexin present in wines and several plants and has a broad spectrum of biological activities, including antioxidant and anticarcinogenic effects. The biological effects of ionizing radiation plus resveratrol have been examined in different types of cell in many studies. Here, we aimed to verify the effects of resveratrol on mucoepidermoid lung carcinoma cells NCI-H292 exposed to ionizing radiation. In vitro studies in NCI-H292 cell culture using neutral red uptake assays showed that the cytotoxicity index (IC50) of resveratrol was 401.5μM, and the lethal dose 50 % (LD50) of ionizing radiation in the absence of resveratrol was 693 Gy. In vitro micronucleus assays were then performed to verify the genotoxic effects of resveratrol, and fluorescence assays were performed to evaluate the effects of resveratrol on the cell cycle, repair and injury processes, cellular necrosis, and apoptosis. The results demonstrated that 30μM resveratrol promote injury on NCI-H292 cells after 24 h of irradiation. Therefore, this study provides results able to support in vitro future investigations about radiosensitive potential of resveratrol in lung cancer cells. There is a need to investigate compounds with potential to improve the local control of lung cancer promoted by radiation therapy. This way avoiding injuries to healthy cells.

    Avaliação dos efeitos da radiação ionizante e do Resveratrol na cultura de células tumorais de pulmão
    2016 - MORENO, CAROLINA dos S.
    O carcinoma mucoepidermóide de pulmão, um tipo histológico que deriva das glândulas mucosas traqueobrônquicas, manifesta-se com sintomas obstrutivos e tende a comprometer a traqueia. Com finalidade curativa ou paliativa da doença, atualmente há uma forte tendência na oncologia em desenvolver estratégias terapêuticas que visam à administração de compostos com elevado potencial de otimizar o efeito do tratamento com a radiação ionizante, de modo a aumentar a morte de células tumorais e preservar íntegras as células dos tecidos sadios adjacentes. A intensa busca por tais estratégias evidenciou resultados promissores apresentados pelo composto denominado Resveratrol (3,4,5-trihidroxiestilbeno), tornando-o amplamente divulgado e alvo de intensas pesquisas. O principal objetivo do presente estudo foi determinar o efeito do resveratrol em cultura celular de carcinoma mucoepidermóide de pulmão exposta a diferentes doses de radiação ionizante. Para tal, os estudos de citotoxicidade utilizando o método de incorporação do vermelho neutro, e da determinação da dose letal 50 % (DL50) da radiação ionizante, foram realizados em cultura de células da linhagem NCI-H292 [H292] (ATCC® CRL-1848TM), CCIAL069. Com base nos resultados do IC50% (401,5 μM) e da DL50 (693 Gy) foram realizados o teste in vitro do micronúcleo e os ensaios para avaliar o efeito do resveratrol no ciclo celular, reparo da lesão no DNA e processo de lesão radioinduzida, necrose e apoptose celular. Os resultados evidenciaram que o resveratrol na concentração de 30 μM apresenta uma importante capacidade em promover danos às células NCI-H292 após 24 h da irradiação.
