Transcriptomics Analysis of Diploid and Tetraploid Worms Exposed to DNA-Damaging Chemotherapeutics

ABSTRACT: To establish the consequences of whole-animal tetraploidy, we generated stable C. elegans worm strains that are tetraploid in every cell in their body and exposed them to DNA damaging chemotherapeutics doxorubicin and cisplatin at doses that do not cause growth delay. Exposures were carried out for 48 h beginning at L1 stage.

Gene expression profile of diploid and tetraploid mouse primary hepatocyte

Project description:Genetically unstable tetraploid cells can promote tumorigenesis. Recent estimates suggest that ~37% of human tumors have undergone a genome-doubling event during their development. This potentially oncogenic effect of tetraploidy is countered by a p53-dependent barrier to proliferation. However, the cellular defects and corresponding signaling pathways that trigger growth suppression in tetraploid cells are not known. Here we combine genome-scale RNAi screening and in vitro evolution approaches to demonstrate that cytokinesis failure activates the Hippo tumor suppressor pathway in cultured cells as well as in naturally occurring tetraploid cells in vivo. Induction of the Hippo pathway is triggered in part by extra centrosomes, which alter small G-protein signaling and activate LATS2 kinase; LATS2 in turn stabilizes p53 and inhibits the transcriptional regulators YAP and TAZ. These findings define an important tumor suppression mechanism. Furthermore, our experiments uncover adaptations that allow nascent tumor cells to bypass this inhibitory regulation. Hepatocytes of newborn mice are initially diploid, but become progressively tetraploid with age. To study the mechanism of cell cycle arrest in naturally occurred tetraploidy, we used microarrays to detail the overall gene expression profile of diploid and tetraploid primary hepatocytes and identified YAP target genes up-regulated in diploid cells.

Comparison of DNA methylation profiles in diploid and transformed tetraploid MEF cells

Project description:We propose that tetraploidy induces epigentic changes including DNA methylation due to the abnormal chromatin in the cells. To test our hypothesis, we employed methylated CpG island recovery assay (MIRA) assisted microarray to determine the DNA methylation profiles in both diploid and tetraploid cells. First, we conducted a methylated-CpG island recovery assay (MIRA). Briefly, we enriched for methylated CpG islands with methylated DNA binding proteins, MBD2/MBD3L1. The pulled down DNA fragments containing CpG islands and input DNA fragments were amplified with real-time PCR. After labeling, they were hybridized to CpG island promoter array. Data were collected and analyzed.

DLD1 Diploid vs Tetraploid

Project description:Tetraploidisation has been implicated in tumorigenesis and in aneuploidy which is frequently observed in most human cancers. In this study we aim to reveal differences in gene expression profile of p53 defective isogenic diploid and tetraploid cell populations. Isogenic DLD1 populations were obtained by transient Dihydro-Cytochalasin B treatment and cell sorting of pure diploid and tetraploid populations by cell cycle profile several days after release from DCB. RNA isolation: Two technical replicas were collected for each population from two different passages (biological replicas) of 60-80% confluent cells.

Transcription profiling of human cell lines treated with cytochalasin D and nocodazole with the aim of characterising tetraploid clones

Project description:During the oncogenic process, tetraploidy is a candidate intermediate stage leading from diploidy to aneuploidy. The aim of our experiment was to establish tetraploid clones and to characterize their transcriptome.

Gene expression in diploid and evolved tetraploid RPE-1 and BJ-1 cells

Project description:Both diploid RPE-1 and BJ-1 cells were made tetraploid by transient treatment with the cytokinesis inhibitor DCD. Proliferating tetraploids from both BJ-1 and RPE-1 were selected and isolated. The gene expression profiles of the proliferating tetraploid cells were then compared to the diploids from which they originated.

Comparison of gene expression profiles in diploid and transformed tetraploid MEF cells

Project description:We propose that abnormal DNA content in tetraploid cells can alter the gene expression profile, contributing to the cellular transformation. To test this hypothesis, we employ mRNA microarray to compare the gene expression profile in transformed tetraploid cells with that in the parent diploid cells. Keywords: gene expression profile determination Total RNA were extracted from diploid or tetraploid cells (n = 3 for each cell lines. mRNA microarray hybridization was conducted. Data were collected and analyzed.
