Project description:miRNA abnormalities are increasingly relevent to cancer development, We used microarrays to detail the global programme of gene expression upon miR-483 overexpression in sarcoma cell line MHH-ES-1. MHH-ES-1 cells were transfected with miR-483-5p, -3p or scrambled control mimics and then harvested 48 hours after to isolate total RNAs using Trizol reagent (Invitrogen). Total RNA was converted to cRNA probes using the BioArray High Yield Transcript Labeling Kit (ENZO diagnostics), and hybridized to Affymetrix GeneChip human HG-U133ver2+ 3’-mRNA expression microarray chips using protocol EukGEs2v4 on the GeneChip Fluidic Station.
Project description:Analysis of differentially expressed genes in wild type MHH-ES-1 Ewing Sarcoma cells when compared to MHH-ES-1 Ewing Sarcoma cells that received six 4 Gy fractions (cumulative dose of 24 Gy) of ionizing radiation (radiation-adapted cell line). The hypothesis tested being that repeated ionizing radiation exposure of modifies radiation therapy response in Ewing Sarcoma.
Project description:MicroRNA-483 (miR-483) regulate endothelial function through inhibition expression of connective tissue growth factor (CTGF). Endothelial dysfunction is involved in the pathogeneis of pulmonary arterial hypertension (PAH). We investigated the role of miR-483 overexpression on human pulmonary arterial endothelial cells (hPAECs) through comparing the transcriptome file of hPAECs transfected with miR-483 -3p and -5p mimic and with control mimic. Gene ontology analysis showed that several PAH-associated signaling pathways were regulated by miR-483, including transforming growth factor-β signaling, Wnt signaling and inflammatory response, cell adhesion, response to hypoxia, apoptotic processes, oxidative reduction processes and negative regulation of cell migration and proliferation.
