Involvement of Src tyrosine kinase and protein kinase C in the expression of macrophage migration inhibitory factor induced by H2O2 in HL-1 mouse cardiac muscle cells

Macrophage migration inhibitory factor (MIF), a pleiotropic cytokine, plays an important role in the pathogenesis of atrial fibrillation; however, the upstream regulation of MIF in atrial myocytes remains unclear. In the present study, we investigated whether and how MIF is regulated in response to the renin-angiotensin system and oxidative stress in atrium myocytes (HL-1 cells). MIF protein and mRNA levels in HL-1 cells were assayed using immunofluorescence, real-time PCR, and Western blot. The result indicated that MIF was expressed in the cytoplasm of HL-1 cells. Hydrogen peroxide (H2O2), but not angiotensin II, stimulated MIF expression in HL-1 cells. H2O2-induced MIF protein and gene levels increased in a dose-dependent manner and were completely abolished in the presence of catalase. H2O2-induced MIF production was completely inhibited by tyrosine kinase inhibitors genistein and PP1, as well as by protein kinase C (PKC) inhibitor GF109203X, suggesting that redox-sensitive MIF production is mediated through tyrosine kinase and PKC-dependent mechanisms in HL-1 cells. These results suggest that MIF is upregulated by HL-1 cells in response to redox stress, probably by the activation of Src and PKC.

Avaliação sensorial de feijão preto submetido à radiação de Cobalto-60

O objetivo dessa pesquisa foi o de avaliar os aspectos sensoriais do feijão preto submetido à radiação gama do 60Co. O estudo envolveu oito provadores, na faixa etária de 17 a 23 anos, selecionados e treinados para Análise Descritiva Quantitativa. Os provadores verificaram alterações quanto à aparência, aroma, sabor e textura em feijão preto irradiado com doses 2, 4, 6, 8 e 10kGy e feijão preto não irradiado. Para a análise estatística dos resultados obtidos foram aplicados, o teste F, ANOVA e o teste de Tukey (5%) com o uso de computadores e do programa específico para análise sensorial Compusense Five e SAS. As amostras irradiadas apresentaram diminuição do sabor amargo, cor acentuada e brilhante e a não irradiada textura seca. Deste modo, a irradiação como método de conservação pode ser utilizada para o feijão preto com as doses avaliadas no presente estudo.
