Project description:The objective of this study was to evaluate the consequences of Ago1 knockdown in metastatic prostate cancer cells PC3. To this end we profiled RNA from PC3 cells 72 hours following the transfection with a scramble siRNA (siGL3) and a siRNA targeting Ago1 (siAgo1). We profiled RNA from PC3 cells 72 hours following the transfection with a scramble siRNA (siGL3) and a siRNA targeting Ago1 (siAgo1). siAgo1 vs siGL3 gene expression profiling, two technical replicates with dye swap labeling scheme.

Project description:PGC-1 related coactivator (PRC) shares structural and functional features with PGC-1{alpha}. It regulates several metabolic pathways and mitochondrial biogenesis. Its specific role in the early programming of cell proliferation suggests a finely regulated crosstalk between the mitochondrial functions and the cell cycle status. To explore the PRC-regulated pathways, we used a cell-line model of mitochondrial-rich tumors, presenting an oxidative metabolism and a specific increase in PRC expression. Microarray studies of temporal PRC invalidation in these XTC.UC1 cells were compared to the functional status of the mitochondria as well as to the expression level of genes and proteins involved in the oxidative phosphorylation process. Compared with what was observed for PGC-1{alpha}, we explored the role of nitric oxide in the PRC-regulated mitochondrial biogenesis. We proved that nitric oxide rapidly influences the expression of PRC at the transcriptional level. Focusing on mitochondrial energy metabolism, we demonstrated that PRC differentially controls the respiratory chain complexes and the coupling efficiency, in order to conserve a sufficient level of ATP and to protect the cell from oxidative stress. Our results highlight the key role of the PRC coactivator in the fine modulation of metabolic functions in response to the cell cycle status. Keywords: Transcriptionnal coactivator invalidation by SiRNA Expression profiles at 0h, 12h, 24h and 48h of PRC SIRNA treatment compared to scramble and referred to time of 20% serum induction. Expression profiles of PRC SIRNA and scramble during serum starvation were referred as -1.

Project description:As part of our study in understanding the role of SP140 in inflammatory pathways in macrophages, we inhibited SP140 mRNA using siRNA. Peripheral blood mononuclear cells (PBMCs) were obtained from whole blood of healthy donors (from Sanquin Institute Amsterdam or from GSK Stevenage Blood Donation Unit) by Ficoll density gradient (Invitrogen). CD14+ monocytes were positively selected from PBMCs using CD14 Microbeads according to the manufacturer’s instructions (Miltenyi Biotec). CD14+ cells were differentiated with 20 ng/mL of macrophage colony-stimulating factor (M-CSF) (R&D systems) for 3 days followed by 3 days of polarization into classically activated (inflammatory) M1 macrophages (100 ng/mL IFN-γ; R&D systems). M1 macrophages were transfected with siGENOME human smartpool SP140 siRNA or non-targeting scrambled siRNA for 48h with DharmaFECT™ transfection reagents according to manufacturer’s protocol (Dharmacon). The cells were left unstimulated or stimulated with 100 ng/mL LPS (E. coli 0111:B4; Sigma) for 4h (for qPCR) or 24h (for Elisa). The cells were lysed (ISOLATE II RNA Lysis Buffer RLY-Bioline) for RNA extraction.150 ng total RNA was labelled using the cRNA labelling kit for Illumina BeadArrays (Ambion) and hybridized with Ref8v3 BeadArrays (Illumina). Arrays were scanned on a BeadArray 500GX scanner and data were normalized using quantile normalization with background subtraction (GenomeStudio software; Illumina).
