Project description:Arnica m. effects were associated with a purported anti-inflammatory and tissue healing actions after trauma, bruises, or tissue injuries, but its cellular and molecular mechanisms are largely unknown. Here Arnica m. dilutions were tested using an in vitro model of macrophages polarized towards a “wound-healing” phenotype. The monocyte-macrophage human THP-1 cell line was cultured and differentiated with phorbol-myristate acetate and Interleukin-4, then exposed for 24 h to Arnica m. centesimal (c) dilutions 2c, 3c, 5c,9c, 15c or Control. None of these treatments affected cell viability. A total of 20 genes were differentially expressed comparing cells treated with Arnica m. 2c with those treated with Control only. Of these, 7 genes were up-regulated and 13 were down-regulated. Functional gene enrichment analysis showed that the most significantly upregulated function concerned 4 genes with a conserved site of EGF-like region (p<0.001) and three genes of proteinaceous extracellular matrix, including heparin sulphate proteoglycan 2 (HSPG2), fibrillin 2 (FBN2), and fibronectin (FN1) (p <0.01). Protein assay in supernatants confirmed a statistically significant increase of fibronectin production in Arnica m. 2c treated cells (p<0.05). Pooled extracts of cells treated with increasing dilutions of Arnica m. (3c, 5c, 15c) showed up-regulation of the same group of genes although with lower effect size. The down-regulated transcripts derive from mitochondrial genes coding for some components of electron transport chain. These findings provide new insights into the action of Arnica m. in tissue healing and repair, identifying increased fibronectin production by macrophages as a major therapeutic target.

Project description:The coordination of chloroplast and nuclear genome status are critical for plant cell function, but the mechanism remain largely unclear. In this study, we report that Arabidopsis thaliana CHLOROPLAST AND NUCLEUS DUAL-LOCALIZED PROTEIN 1 (CND1) maintains genome stability in both the chloroplast and the nucleus.

Project description:Most northern insect species experience a period of developmental arrest, diapause, which enables them to survive over the winter and postpone reproduction until favorable conditions. We studied the timing of reproductive diapause and its long-term effects on the cold tolerance of Drosophila montana, D. littoralis and D. ezoana females in seasonally varying environmental conditions. At the same time we traced expression levels of 219 genes in D. montana using a custom-made microarray. We show that the seasonal switch to reproductive diapause occurs over a short time period, and that overwintering in reproductive diapause has long-lasting effects on cold tolerance. Some genes, such as Hsc70, Jon25bi and period, were upregulated throughout the diapause, while others, including regucalcin, couch potato and Thor, were upregulated only at its specific phases. Some of the expression patterns induced during the sensitive stage, when the females either enter diapause or not, remained induced regardless of the later conditions. qPCR analyses confirmed the findings of the microarray analysis in D. montana and revealed similar gene expression changes in D. littoralis and D. ezoana. The present study helps to achieve a better understanding of the genetic regulation of diapause and of the plasticity of seasonal responses in general. Custom made DNA microarray for Drosophila montana and D. virilis. Current experiment includes 8 samples (7 to 250 days old diapausing or non-diapausing D. montana females) with two or three biological replicates
