Project description:FCCP, Oligomycin and AMP lead to mitochondrial dysfunction. Here the influence of FCCP, Oligomycin and AMP on the transcriptome of PFF is examined.
Project description:Changes in gene expression in lymph node and kidney of cattle infected with alcelaphine herpesvirus-1. All animals in the group infected with AlHV-1 showed clinical signs of Malignant catarrhal fever (MCF) within one month. Diagnosis of MCF in these animals was confirmed by diagnostic PCR. No clinical signs were seen in the control animals, which were subject to post-mortem examination separately from the MCF-affected animals. RNA samples from kidney and lymph node of 4 MCF-affected and 4 control animals that passed the RNA quality criteria were used for array analysis. Quality assessments of probe-level Affymetrix chip data and normalised data were carried out using statistical and graphical methods including MA plots and smoothed histogram plots. The MA-plots showed normalisation was effective; while smoothed histograms indicated there was no systematic bias in the data.
Project description:We used RNAi to knock-down the two isoforms of Asf1, Asf1a and Asf1b, in human U-2-OS osteosarcoma cells. We obtained two replicates each with siRNAs against Asf1a, Asf1b, combined siRNAs against both isoforms, and two control samples. For these samples, we measured genome-wide transcription levels using Affymetrix HG-U133Plus2 oligonucleotide microarrays.
Project description:The liver possesses remarkable regenerative capacity in response to injury. Upon partial hepatectomy (PHx), terminally differentiated hepatocytes in the remaining liver enter the cell cycle and restore the liver mass and function within weeks. However, liver regeneration is often impaired in livers with chronic diseases. Survivin, an inhibitor of apoptosis protein (IAP) and member of chromosome passenger complex (CPC), plays versatile roles in cell mitosis and apoptosis. We and others found that the expression of Survivin was highly increased in liver during PHx-induced liver regeneration, which indicated that Survivin played important roles in this process. However, the function of Survivin in liver regeneration remains largely undefined. Here, using mice with genetic deletion of Survivin, we found that during PHx-induced liver regeneration Survivin regulated both hepatocyte G1/S phase transition by inhibiting the expression of p21 and G2/M phase transition by regulating the localization of CPC. Moreover, restoration of Survivin expression in Survivin-deficient hepatocytes inhibited p21 expression and promote both hepatocyte G1/S and G2/M transition during PHx-induced liver regeneration.
Project description:We have used normal, tumoral and pure stromal whole tissue samples, and cells lines in order to identify new markers of prostate cancer.<br>The normal, tumoral and stromal tissue were obtained from patients diagnosed with prostate adenocarcinoma.<br>
Project description:We decreased TAL1 and NKX3.1 proteins levels using lentiviral deliveries of shTAL1 and shNKX3.1 in TAL1 expressing human T-ALL cell lines. Growth curves of cell lines showed that reduced TAL1 and NKX3.1 expressions resulted in a first phase where the number of cells did not increase likewise the shCTL expressing cells. To identify TAL1 and NKX3.1 target genes involved in T-ALL cell growth, we performed gene expression profiling of cell lines expressing shTAL1, shNKX3.1 or shCTL after two and three days of culture. <br><br><br><br>
