Project description:In order to understand which pathways are involved and what genes are affected when small T is expressed in mammalian cells, we carried out microarray analaysis in these cell lines Total cellulatr RNA was isolated at 20 hrs after doxycycline addition in samples 2,4 and 6 (+DOX), and was subjecyed to microarray analysis using Affymetrix Human Genome U133 Plus 2.0 (HG-U133_Plus_2) chips.
Project description:To better understand the mechanism by which CFZ impacts polyQ toxicity, we conducted a transcriptomic analysis in polyQ94-EGFP expressing U2OS (5μM, 8 days). Data from a transcriptomics experiment in polyQ94-U2OS cells treated with CFZ (5 μM, 8day) was compared to a DMSO-treated control.
Project description:Bulk RNAseq analysis was done on single cell clones of U2OS cells either expressing exogeonous CIITA or an empty vector control to identify genes regulated by CIITA expression.
Project description:We performed DNase-seq on two osteosarcoma cell lines, Saos-2 and U2OS. This was done to identify regulatory regions within the genomes of these cells. We performed hotspot calling on these data using Hotspot2 (https://github.com/Altius/hotspot2) to identify 51,556 DNaseI hypersensitive sites within Saos-2 cells and 63,388 within U2OS cells.
Project description:CRISPR screen: U2OS or U2OS p53KO cells expressing Cas9 were transduced with a whole-genome library of CRISPR sgRNAs, then treated with either DMSO or etoposide. Differential sgRNA abundances were calculated for each condition and used to determine the effect of each single gene knockout on fitness and the drug-induced death rate. RNA-Seq: U2OS or U2OS p53KO cells were cultured with either DMSO or etoposide for 48 hours, and then U2OS cells were incubated in this conditioned media for 8 hours. RNA was collected and use to observe differential expression changes between conditions.
Project description:CRISPR-Cas9 was used to individually knock out SUMO1 and SUMO2 expression in U2OS cells. The transcriptomes of SUMO1 and SUMO2 knockout (KO) cell lines were analyzed using RNA-sequencing.
Project description:PRDM5 is a recently identified member of the PRDM family of proteins, which functions as a transcriptional repressor by recruiting histone methyltransferase G9A to DNA, and behaves as a putative tumor suppressor in different types of cancer. We investigated PRDM5 function by identifying its target genes in U2OS cells at different time points after expression of PRDM5 protein. Experiment Overall Design: We analyzed gene expression profiles of a U2OS cell line conditionally expressing HA-tagged PRDM5 (U2OS-PRDM5), where PRDM5 is under the transcriptional control of a doxycycline-inducible promoter. Expression of PRDM5 protein is detectable after 8 hours of induction with 2ug/ml doxycycline, and increases steadily up to 48 hours, after which cells begin to undergo apoptosis. U2OS cells containing the empty cloning vector (U2OS-pSG213) were used as controls for each condition.
