Project description:miRNA expression profiles of WI38 primary human fibroblasts with an active or inactive p53. Cells were compared under normal untreated conditions (young and proliferating cells), after DNA damage with Doxorubicin, and upon entry into replicative senescence. Keywords: miRNA, WI-38, p53, GSE56, Senescence, Doxorubicin, Cancer, DNA-damage, fibroblasts.

Cells were compared under normal untreated conditions (young and proliferating cells), after DNA damage with Doxorubicin, and upon entry into replicative senescence. Keywords: miRNA, WI-38, p53, GSE56, Senescence, Doxorubicin, Cancer, DNA-damage, fibroblasts. 6 samples of WI38 cells were analyzed on 12 Exiqon miRcurry LNA arrays in biological duplicates (2 different cell culture plates for each experimental condition). The six conditions included: 1. [Con_Young] - Primary Young WI38 cells (passage 20) with a control retroviral vector (pLXSN-NEO). Untreated. 2. [GSE_Young] -Primary Young WI38 cells (passage 20) with a retroviral vector encoding for the p53-inactivating peptide GSE56 (pLXSN-NEO-GSE56).Untreated. 3. [Con_Dox] -Primary Young WI38 cells (passage 20) with a control retroviral vector (pLXSN-NEO). Treated with Doxorubicin (0.2 micrograms/ml) for 24 hours). 4. [GSE_Dox] Primary Young WI38 cells (passage 20) with a retroviral vector encoding for the p53-inactivating peptide GSE56 (pLXSN-NEO-GSE56). Treated with Doxorubicin (0.2 micrograms/ml) for 24 hours). 5. [Con_Old] - Sesescent WI38 cells (passage 30) with a control retroviral vector (pLXSN-NEO). Untreated. 6. [GSE_Old] - Senescent WI38 cells (passage 26) with a retroviral vector encoding for the p53-inactivating peptide GSE56 (pLXSN-NEO-GSE56).Untreated. RNA was extracted with TRI-Reagent and sent for labeling and hybridization in Exiqon laboratories (In Denamark). Samples were labeled with Cy5. Reference sample (Cy3) was an RNA mix of all samples. Log2 for Ratio(Cy5/Cy3) was used for further analysis.

Project description:Transcriptome analysis of control and MALAT1 lncRNA-depleted RNA samples from human diploid lung fibroblasts [WI38] The long noncoding MALAT1 RNA is upregulated in cancer tissues and its elevated expression is associated with hyper-proliferation, but the underlying mechanism is poorly understood. We demonstrate that MALAT1 levels are regulated during normal cell cycle progression. Genome-wide transcriptome analyses in normal human diploid fibroblasts reveal that MALAT1 modulates the expression of cell cycle genes, and is required for G1/S and mitotic progression. Depletion of MALAT1 leads to activation of p53 and its target genes. The cell cycle defects observed in MALAT1-depleted cells are sensitive to p53 levels, indicating that p53 is a major downstream mediator of MALAT1 activity. Furthermore, MALAT1-depleted cells display reduced expression of B-MYB (Mybl2), an oncogenic transcription factor involved in G2/M progression, due to altered binding of splicing factors on B-MYB pre-mRNA and aberrant alternative splicing. In human cells, MALAT1 promotes cellular proliferation by modulating the expression and/or pre-mRNA processing of cell cycle-regulated transcription factors. These findings provide mechanistic insights on the role of MALAT1 in regulating cellular proliferation. We analyzed RNA from control and MALAT1 depleted WI38 cells using the Affymetrix Human Exon 1.0 ST platform. Array data was analyzed by Partek Genomic Suite software.

Project description:The interaction between cancer and stroma plays a key role in tumor progression. Inactivation of p53 is often observed in stromal cells surrounding in cancer, suggesting that p53 in fibroblasts is involved in tumor progression. To elucidate the mechanism by which p53 loss in fibroblasts effect on proliferation and invasiveness of cancer cells, we performed comprehensive expression profiling analyses between p53 knockdown and control fibroblasts using GeneChip Human Genome U133 plus 2.0 arrays. Intact human fetal lung normal diploid fibroblasts TIG-7 cells and TIG-7 cells infected with lentiviruses for the expression of shRNA against p53 were used for RNA extraction and hybridization on Affymetrix microarrays.
