Project description:RNA helicase A (RHA) binds its target transcripts at the post-transcriptional control element (PCE) located in the 5’ untranslated region (UTR). This interaction represents an “RNA switch” that regulates protein synthesis. Down regulation of RHA by siRNAs was used to identify transcripts with RHA-dependent translation. Reduced accumulation of RNA in polysomes was monitored with microarrays. Cytoplasmic lysates of cells treated with RHA targeted or non-silencing control siRNAs were separated by sucrose density gradient centrifugation. Ribosomal RNA profiles were generated, containing heavy polysomes were collected, and RNA was extracted.

Project description:Human umbilical vein endothelial cells (HUVECs) were transduced with either MIY-N1IC (Notch1 intracellular domain) or MIY vector control. The cells were sorted for YFP, and RNA was extracted using Trizol (Invitrogen) and analyzed by the Affymetrix Human Genome U133 Plus 2.0 Array. Results were analyzed using the GCRMA algorithm to identify genes with a minimum of 2-fold induction or reduction. This global gene expression study was used to identify Notch targets in the endothelium. Expression profiling of primary HUVECs transduced with N1IC. HUVEC primary cells were isolated, transduced with N1IC or vector (MIY) control in three biological replicates, and evaluated on Affymetrix Human Genome U133 Plus 2.0 arrays.
Project description:The objective of this study was to determine the effects of LANA on the expressions of the cellular genes. BJAB cells were transduced with lentiviral vector expressing LANA or the control vector, total RNA was extracted for the detection of relative expression of cellular genes in LANA expressing cells.
