DDB2 regulates gene expression in ovarian cancer cell lines
Ontology highlight
ABSTRACT: DDB2 has been suggested to function as a transcription regulator in various cancer cell lines. We stably overexpressed DDB2 in ovarian cancer cell line A2780-CP70, and compared the gene expression profiles between DDB2-overexpressed and empty vector-transfected cells. Empty vector and DDB2-expressing vector were transfected into A2780-CP70 separately. The stable transfection clones were selected, and gene expression patterns in these clones were investigated through microarray analysis.

Project description:V5 tagged JMJD6 was stably overexpressed in MCF7 cells (JOE); empty vector transfected MCF7 cells were used as a control (Vec). Transcription profiling was carried out is duplicate.
Project description:Total RNA samples from three biological replicates in which TFEB was transiently overexpressed in HeLa cells by transfection using a pcDNA3 vector. As negative control, we used total RNA samples from HeLa cells transfected with an empty pcDNA3 vector.
Project description:This SuperSeries is composed of the following subset Series: GSE28646: Gene expression profiling in A2780, CP70 and CP70 following Decitabine and/or PXD101 treatment GSE28647: Genome-wide methylation profiling identifies candidate DNA methylation drivers of acquired cisplatin resistance in ovarian cancer.

Project description:The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across 485,577 CpGs . Samples included 11 clones of each of the four groups derived from the A2780/CP70 ovarian cancer cell line. Groups included MLH1 minus treated with 5uM Cisplatin (A), MLH1 plus treated with 5uM Cisplatin (B), MLH minus mock treated (C) and MLH1 plus mock treated (D).
Project description:Alzheimer's disease (AD) is characterized by massive neurodegeneration and multiple changes in cellular processes, including neurogenesis. Proteolytic processing of the amyloid precursor protein (APP) plays a central role in AD. Due to varying APP processing, several beta-amyloid peptides are generated. In contrast to the form with 40 amino acids, the variant with 42 amino acids is thought to be the pathogenic form triggering the pathophysiological cascade in AD. Here, we studied the transcriptomic response to increased or decreased Abeta42 levels generated in human neuroblastoma cells. Genome-wide expression profiles (Affymetrix)were used to analyze the cellular response to the changed Abeta42 and Abeta40-levels. <br><br>Human neuroblastoma cell line SH-SY5Y is a thrice cloned (SK-N-SH -> SH-SY -> SH-SY5 -> SH-SY5Y) subline of the neuroblastoma cell line SK-N-SH which was isolated and established in 1970. This cell line has 47 chromosomes. The cells possess a unique marker comprised of a chromosome 1 with a complex insertion of an additional copy of a 1q segment into the long arm, resulting in trisomy of 1q. The cell lines used in this study are SHSY5Y transfected with the constructs pCEP-C99I45F, pCEP-C99V50F, pCEP-C99 wildtype or mock transfected with an empty vector. Independent cell clones of each transfected line were used to provide biological replicates.<br> Overexpressed C99 I45F is intracellularly cleaved resulting in high Abeta42, but low Abeta40 levels.<br> Overexpressed C99V50F is intracellularly cleaved resulting in low Abeta42, but high Abeta40 levels.<br>Overexpressed C99 wildtype is intracellularly cleaved resulting in medium Abeta42 and Abeta40 levels<br>Mock is the SHSY5Y cell line transfected with the empty vector pCEP (Invitrogen) as a negative control

Project description:A novel alternative splicing isoform of LOXL2 â³e13 was expressed ubiquitously in all cell lines and ESCC tissues. In contrast to the impaired deamination enzymatic activity compared with full length LOXL2, LOXL2 â³e13 showed an enhanced ability to promote cell mobility and invasiveness in ESCC cells than full length LOXL2 through a different mechanism. We used cDNA microarrays to identify genes that were differentially expressed upon LOXL2 â³ e13 overexpressed. For this purpose, we selected LOXL2 â³ e13, WT and empty vector control transfeced ESCC KYSE150 cell lines. Total RNA was extracted,compare the gene expression patterns between LOXL2 â³e13, LOXL2 WT and empty vector control transfected cells through the Genechip Primeview Human Gene Expression Array.
