Contrarily, under cyclophosphamide treatment the bioluminescence signal was hardly detectable one day after infection, but steadily increased at later time points (Figure 2, inlet). As assumed,

the amount of fungal DNA detected one day after infection in cortisone acetate treated animals was generally higher than that of cyclophosphamide treated animals at the same time point, confirming an increased early germination rate of conidia under corticosteroid treatment. Surprisingly, the quantity of fungal DNA stayed rather constant under the corticosteroid regimen. This implies that the immune response 7-Cl-O-Nec1 under this treatment either prohibits further growth of hyphae or even kills fungal cells, which could explain the decrease in the bioluminescence signal. However, lungs explanted from mice sacrificed at day three still showed significant luminescence (Figure 1D and 2). Therefore, we assume that, besides reducing the expansion of fungal mycelium through the lung tissue, neutrophils cause extensive tissue destruction leading to tissue

hypoxia, which could attenuate the bioluminescence signal. Oxygen is an essential substrate for firefly luciferase activity DZNeP concentration and an oxygen saturation below 5% significantly decreases light emission [19]. Figure 2 Quantitative real-time PCR of fungal DNA enables the selleck chemical correlation between fungal burden and bioluminescence signals. Mice were immunosuppressed either with cortisone acetate or cyclophosphamide. Two mice from each group were sacrificed at day one and the other two animals from each group at day three after infection. An uninfected mouse was used as a negative control and revealed no signal in the qRT-PCR and is, therefore, omitted from the graph. The bars represent the amount of fungal DNA per microgram of total DNA isolated from the infected tissues with standard deviations from six data points for each individual animal. The two animals investigated for each time point and immunosuppression regimen

show the general tendency that at day one after infection the cortisone acetate treated animals show a higher burden than the cyclophosphamide treated animals. Three days after infection, the burden with alive fungal cells seems to stay rather constant under the coticosteroid treatment, MRIP but strongly increases under the regimen with cyclophosphamide. The inlet shows the time response of bioluminescence from alive animals with high values for the cortisone acetate treated mice early after infection followed by a decline of the signal intensity at later time points. Under cyclophosphamide regimen the bioluminescence steadily increases. The small photographs above the bars from mice sacrificed at day three show the explanted lungs with an overlay of the emitted light intensities. Numbers above the photographs give the photons/s × cm2.

For time contrast 6–3 weeks, one gene was up-regulated (log FC 1.0). DLEC1, Deleted in lung and esophageal cancer 1, a tumor suppressor gene that may be a potential

negative regulator of cell proliferation [29]. Top table analysis resection group All discussed genes in this chapter are illustrated in Figure 4. Amongst up-regulated genes in the resection group there was in early time period (from t = 0 until t = 1), a predominance of genes regulating transcription, intracellular and cell-cell signalling, extracellular matrix/cytoskeleton and inflammation, whereas genes governing the cell cycle were evenly expressed throughout the experiment. Towards the end of the experiment (from t = 1 until t = 2), we found an increase in up-regulation for genes controlling lipid, hormone, amine, alcohol metabolism and transport. Figure 4 Functional classification of all BAY 63-2521 price genes according to ARS-1620 in vitro Online Mendelian Inheritance in Man and Ace View. Amongst down-regulated genes in the resection group there was an increase in

number of genes controlling cell cycle and transcription towards the end of the experiment (from t = 1 until t = 2). Genes regulating transport, inflammation and lipid, hormone, amine, alcohol metabolism and transport were only down-regulated in the earliest time period (from t = 0 until t = 1). PX-478 in vivo The expressions of genes regulating cell proliferation were down-regulated at three weeks, whereas genes regulating protein metabolism remained stable. We found a predominance of down-regulated genes regulating intracellular and cell-cell signalling towards the end of liver regeneration. Top table analysis sham group Amongst up-regulated genes within the sham group, we found from t = 0 until t = 2 a gradual increase in the differential expression of genes controlling cell cycle, transcription and transport. From t = 1 until t = 2, there was a gradual increase in the differential expression of genes governing translation.

From t = 0 until t = 1 there was a gradual decrease in expression of genes regulating protein metabolism. In addition, genes regulating intracellular and cell-cell signalling decreased towards the end of the experiment. Genes regulating TGF-beta inhibitor inflammation and extracellular matrix/cytoskeleton were only up-regulated from t = 0 until t = 1. Amongst down-regulated genes in the sham group, there was a decrease in down-regulation of genes controlling cell cycle, transcription, transport, extracellular matrix/cytoskeleton and lipid, hormone, amine, alcohol metabolism from t = 0 until t = 1. However, genes controlling transcription, transport, protein metabolism and lipid, hormone, amine, alcohol metabolism increased again towards the end of the experiment. Down-regulated genes controlling intracellular and cell-cell signalling increased in expression from t = 0 until t = 2, whereas genes regulating cell proliferation decreased over all time periods.
