Gene profiling: U87 IRE1 dominant negative cells vs. U87ctrl cells in culture

Project description:Transcriptome analysis was performed from human U87 glioblastoma cell clones: U87 IRE1.NCK DN (U87dn, IRE1 dominant negative) and U87 control (U87ctrl, empty plasmid). Cells were grown in DMEM supplemented with 10% FBS and glutamine for 16 hours in culture prior mRNA isolation and analyses U87dn cells expressing a dominant negative transgene of IRE1alpha were compared to U87ctrl cells transfected with the corresponding empty plamid to identify genes associated to tumor invasion and angiogenesis.

IRE1-dependent transcriptome remodelling upon ER stress in human glioma cells

Project description:We investigate the contribution of IRE1 signaling to the modulation of U87 glioma cells transcriptome upon various stresses. To this end, IRE1 control and IRE1 dominant negative expressing U87 glioma cells were subjected to environmental or chemical challenges and their transcriptome monitored using Affymetrix microarrays.

IRE1 modulates expression of a set of tumor suppressor miRNAs in luminal breast cancer cells.

Project description:To explore the regulatory mechanism by which inositol-requiring enzyme 1 (IRE1) regulates oncogenic factors, particularly RAB3B, in luminal breast cancer cells, we blocked IRE1 activity in breast cancer cell lines by using the IRE1 inhibitor 4μ8C or expressing IRE1 dominant-negative for miRNA microarray analysis. SUM52 and SUM225 lines with high-level IRE1 expression were treated with 4μ8C for 2 days. The IRE1 kinase dominant-negative mutant K599A or K907A was also used to suppress IRE1 kinase or RNase activity in SUM52 cells. The miRNA microarray analysis revealed a landscape change in miRNA expression profiling in IRE1-inhibited luminal breast cancer cells. Using a criterion of p < 0.05 in miRNA analysis, we identified 41 miRNAs in both SUM52 and SUM225 cells that were altered after inhibiting IRE1 activity. Additionally, we exogenously overexpressed wild-type IRE1 in human nontumorigenic mammary epithelial MCF10A cells and then performed miRNA array assays. When we combined miRNA data from both IRE1 inhibition models in breast cancer cells and exogenous overexpression of IRE1 in MCF10A cells (p<0.05), we identified 5 miRNAs (3607-3p, 374a-5p, 4764-3p, 516a-3p, and 6073) that were upregulated in IRE1-inhibited breast cancer cells and downregulated in MCF10A-IRE1 cells.

The UPR Transducer IRE1 Promotes Breast Cancer Malignancy by Degrading Tumor Suppressor microRNAs

Project description:To understand the mechanistic basis by which inositol-requiring enzyme 1 (IRE1) is involved in luminal breast cancer malignancy, we analyzed the transcriptomic signature that IRE1 regulates in breast cancer. We suppressed the activity of IRE1 RNase in luminal breast cancer SUM52 line by adenoviral-based over-expression of the IRE1 dominant-negative K599A or K907A, and then performed RNA-sequencing (RNA-seq) analysis with IRE1 dominant-negative and control SUM52 cells. Through the RNA-seq analysis, we identified 98 genes that were commonly upregulated (65 genes) or downregulated (33 genes) in K599A-expressing SUM52 (SUM52-K599A) or K907A-expressing SUM52 (SUM52-K907A) cells.

Microarray analysis of glioma cell lines : Temozolomide Sensitive vs. Resistant

Project description:Transcriptional profiling of glioma cells comparing control U87(Temozolomide sensitive) cells with U87R(Temozolomide resistant). The U87 cell line was given a low dose of temozolomide in culture media for 3 weeks, resulting in the formation of temozolomide-resistant cells made as U87R.
