Detection of transcriptome changes caused by overexpression of NeuroD4 in U251 glioblastoma cells

Project description:We demonstrated that overexpression of NeuroD4 can reprogram GBM cells into neuron-like cells. In order to further explore the mechanism of NeuroD4 causing this phenomenon, we performed mRNA sequencing on U251 cells infected with GFP and GFP+NeuroD4.

Expression data from PARK2 overexpression in U251 cells

Project description:PARK2 (PARKIN) is an E3 ubiquitin ligase whose dysfunction has been associated with the progression of Parkinsonism and human malignancies, and its role in cancer remains to be explored. In this study, we investigated its role in glioma. We used microarrays to detail the global programme of gene expression upon PARK2 overexpression in U251 cells U251 cells with PARK2 overexpression or control (GFP) were subjected for RNA extraction and hybridization on Affymetrix microarrays.

Transcriptome of U251 cells overexpression complement component 7

Project description:We identified a rare coding variant (p.K420Q) in the complement component 7 (C7) gene affecting the risk of Alzheimer's disease. To investigate the cellular effects of the mutant, we performed RNA-seq in cell line overexpression wilt-type and mutant C7. U251 glioma cells with stable expression of mutant APP (K670N/M671L) (U251-APP cells), which produce Aβ42 under Dox inducing, were used as the model cell. Total RNA of U251-APP cells overexpressing wild type and mutant C7 proteins were subjected to transcriptome sequencing using Illumina Hiseq 4000 platform.

Transcriptome (RNA-Seq) of the stable overexpression of lncRNA XLOC013218 U251 cells

Project description:We present RNA-Seq data obtained from U251 control cells and U251 cells with stable overexpression of lncRNA XLOC13218 to identify differentially expressed genes. The discovery of long non-coding RNAs (lncRNAs) has improved the understanding of development and progression in various cancer sub-types. However, the role of lncRNAs in temozolomide (TMZ) resistance in glioblastoma (GBM) remains largely undefined. In this present study, the differential expression of lncRNAs were identified between U87 and U87TR (TMZ-resistant) cells. LncRNA XLOC013218 (XLOC) was drastically upregulated in TMZ-resistant cells and was associated with poor prognosis in glioma. Overexpression of XLOC markedly increased TMZ resistance, promoted proliferation, and inhibited apoptosis in vitro and in vivo. In addition, RNA-seq analysis and gain-of-function or loss-of-function studies revealed that PIK3R2 was the potential target of XLOC. Mechanistically, XLOC recruited Specificity Protein 1 (Sp1) transcription factor and promoted the binding of Sp1 to the promoters of PIK3R2, which elevated the expression of PIK3R2 in both mRNA and protein levels. Finally, PIK3R2-mediated activation of the PI3K/AKT signaling pathway promoted TMZ resistance and cell proliferation, but inhibited cell apoptosis. In conclusion, these data highlight the vital role of XLOC/Sp1/PIK3R2/PI3K/AKT axis in GBM TMZ resistance.

Low cytosolic folate cycling is a hallmark of U251 glioblastoma cells reprogramming towards pluripotency [RNA-seq]

Project description:we report that U251 glioblastoma tumor spheres exhibit low cytosolic folate cycle and a reprogrammmed mitochondrial folate cycle that is presumably oriented towards oxidizing the formyl group to CO2 with the production of TetraHydroFolate and release of NADPH instead of synthesizing formate
