Project description:To unravel the molecular function of TAPIR-1 and -2, four different specific siRNAs were used to knockdown the TAPIR-transcripts in LNCaP-cells. Gene expression changes upon knockdown of TAPIR was assessed by Agilent SurePrint G3 Human Gene Expression Arrays at 24h and 48h after treatment.
Project description:Our observation suggest that ADAR may play important role to maintain GSC stemness. In order to address this hypothesis, we abrogated the expression of ADAR in GSCs using two distinct short and non-overlapping shot hairpin RNAs (shRNAs). A non-targeting control shRNA (shCONT) is used as control in these experiments. Both shRNAs significantly reduced ADAR protein expression. Depletion of ADAR impaired GSCs proliferation but did not affect matched DGCs. Similarly, lack of ADAR reduces GSC self-renewal capacity as assessed by in vitro limiting dilution assay . In order to identify the antitumor mechanisms triggered by ADAR depletion, we performed global transcriptional profiling through RNA-sequencing in GSCs upon ADAR knockdown. These analyses show that ADAR downregulation impairs the impairs the expression of genes involved in cancer proliferation, particularly those involved in cell cycle regulation

Project description:Micro RNAs (miRNAs) miR-130a, miR-203 and miR-205 are jointly downregulated in prostate cancer and act as repressors of AR-signaling. MiRNAs are small non-coding RNAs that regulate the expression of specific mRNA targets mainly by translational repression, mRNA deadenylation or cleavage. Reconstitution of these lost miRNAs in the LNCaP PCa cell line cause morphology changes, growth arrest, and apoptosis, increasing when the miRNAs were co-expressed. Bioinformatic target prediction, mRNA expression and protein expression analysis upon overexpression of these miRNAs congruently identified targets known to be overexpressed in PCa and to be involved in AR trans-activation. This series profiles loss in mRNA expression in LNCaP cells transfected with one of the three miRNAs miR-130a, miR-203 and miR-205 compared to LNCaP cells transfected with a scramble miRNA.
Project description:SLC45A3-ELK4 is found in LNCaP and other prostate cancer samples. We used microarrays to detail the global changes of gene expression when LNCaP cells were treated with siRNAs against SLC45A3-ELK4. We transfected LNCaP cells with siRNAs against SLC45A3-ELK4 and siGl2 control. 72hrs later, RNAs were harvested.
