The gene expression upon dominant negative form of GAS2 (GAS2DN) in MEG-01 cells
Ontology highlight
ABSTRACT: GAS2DN could suppress the growth of chronic myeloid leukemia cells, including K562, MEG-01 and CD34+ cells from patients. In addition, GAS2DN inhibited the tumorigenic ability of MEG-01 cells in nude mice. To understand the molecular insight of this inhibitory effect of GAS2DN, global gene expression were performed. The control and GAS2DN-transduced MEG-01 cells were used for microarray analysis. Three biological independent extracts of control and GAS2DN-transduced cells were pooled together with equal amount, and then the pooled samples were compared with Affymetrix chips.

Project description:Transcriptional profiling of the effect of shRNA silencing of Runx1 in human AMkL Meg-01 cells. RNA samples obtained from two independent colonies were compared to RNAs from negative control transductions in a two-color design. A total of four microarrays were completed, with a dye-swapped pair performed for each colony.

Biological replicates: 2 knockdown replicates, 2 control replicates.
Project description:Platelets are produced by megakaryocytes, deriving from megakaryocyte erythrocyte progenitors (MEP) in the bone marrow. Increased megakaryocyte expansion across common autoimmune diseases was shown for rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and primary Sjögren’s syndrome (pSS). In this context, we evaluated the role of the microbial-derived short chain fatty acid (SCFA) propionate on megakayriocytes in vitro. Using RNA sequencing we characterized the consequences of propionate exposure on the megakaryoblast cell line Meg-01.
Project description:Platelets from sickle cell disease patients have differentially expressed microRNAs as compared to platelets from healthy control subjects. The objective of this study is to overexpress an upregulated miRNA,miR-1225-3p, in MEG01 cells to identify putative targets. MEG-01 cells were transfected with microRNA-1225-3p mimic for overexpression. Simultaneously, a negative control (scrambled) RNA was transfected for comparison. Gene expression was measured at 24 hours after transfection. Five independent experiments were performed at the same time in each group: microRNA-1225-3p transfected and scrambled.
Project description:MLS000408882-01 and MLS000573813-01 were identified through a cell based screen that measures the reactivation of an epigenetically silenced transgene. MLS000408882-01 and MLS000573813-01 shows selectivity for cancer vs. normal cells affecting both transcriptional patterns and cell viability in a cancer specific manner.
Project description:The K562 cell line was obtained from ATCC (American Type Culture Collection, Manassas,VA). And the K562 cell line was transduced using a highly efficient retroviral vector coding HLA-A*11:01. The vectors were transfected into a 293T packaging cell line and replication-defective virus supernatants were harvested. After infection of K562 cells with the supernatant, antibody-directed flow cytometry sorting was done to obtain high expression for HLA-A*11:01. Cells were grown in T75 flasks to a density of 1e9 cells before purification of HLA-I peptides for MS experiments.
Project description:We used the microarray data to analyze host cells response on A549 cells infected with A/Duck/Malaysia/01 (H9N2) The A/Duck/Malaysia/01 (H9N2) infected A549 cells were harvested at 2, 4, 6, 8 and 10 hpi and RNA extraction was performed using standard protocol as described by Affymetrix. The aim of this experiment is to analyze host response to Influenza A/Duck/Malaysia/01 (H9N2) infection.
