Expression data from HeLa cell lines stably expressing shRNA targeting ctrl or UHRF1

ABSTRACT: We used microarrays to explore the expression profile from cells expressing wild type and UHRF1 S674A mutant. HeLa cells expressing UHRF1 WT and S674A mutant showed similar gene expression pattern without significant affecting the transcription of DNA repari genes.

Expression data from HeLa cell lines stably expressing shRNA targeting ctrl or UHRF1

Project description:We used microarrays to explore the expression profile from cells expressing wild type and UHRF1 S674A mutant. HeLa cells expressing UHRF1 WT and S674A mutant showed similar gene expression pattern without significant affecting the transcription of DNA repari genes. UHRF1 was depleted in HeLa cells by shRNA treatment. Total RNA was purified and used to determine the global gene transcription profiles by microarray assays. The UHRF1-related genes expression profiles were compared among control cells, UHRF1-depleted cells, UHRF1 WT reconstituting cells and UHRF1 S674A mutant reconstituting cells.

Epigenome analyses of HCT116 cells stably expressing UHRF1 mutant [Illumina EPIC]

Project description:UHRF1 is a key regulator of DNA methylation maintenance. In this study, we investigated whether acetylation of UHRF1 affects its hemimethylated DNA binding affinity and alters genome-wide DNA methylation pattern. We show that cells with mutation in K490 of UHRF1 have distinct methylation profile versus wildtype UHRF1 expressing cells.

Expression data from Hela cells stably expressing the wild-type preS and the three mutant preS

Project description:In large cohort studies, several preS mutants were identified as independent risk factors for HCC risk.In order to study the carcinogenic mechanism between different mutants, HeLa cell lines expressing wild type and different mutated preS proteins were constructed. We used microarrays to describe gene expression in HeLa cells stably expressing the wild-type preS and the three mutant preS, and to identify distinct classes of up-regulated genes.

Gene expression profiles of uhrf1 mutant zebrafish

Project description:UHRF1 (Ubiquitin-like, containing PHD and RING finger domains, 1) recruits DNMT1 to hemimethylated DNA during replication, is essential for maintaining DNA methylation patterns during cell division and is suggested to direct additional repressive epigenetic marks. Uhrf1 mutation in zebrafish results in multiple embryonic defects including failed hepatic outgrowth, but the epigenetic basis of these phenotypes is not known. We find that DNA methylation is the only epigenetic mark that is depleted in uhrf1 mutants and make the surprising finding that despite the reduced organ size in uhrf1 mutants, genes regulating DNA replication and S-phase progression were highly upregulated. Further, there is a striking increase in BrdU incorporation in uhrf1 mutant cells, and they retained BrdU labeling over several days, indicating they are arrested in S-phase. Moreover, some of the label retaining nuclei co-localized with TUNEL positive nuclei, suggesting that arrested cells are responsible for apoptosis. Importantly, dnmt1 mutation phenocopies the S-phase arrest and hepatic outgrowth defects in uhrf1 mutants and Dnmt1 knock-down enhances the uhrf1 hepatic phenotype. Together, these data indicate that DNA hypomethylation is sufficient to generate the uhrf1 mutant phenotype by promoting an S-phase arrest. We thus propose that cell cycle arrest is a mechanism to restrict propagation of epigenetically deranged cells during embryogenesis. Genome-wide expression profiling was performed on 2 uhrf1 mutant and 2 wildtype zebrafish larvae (120 hours post fertilization) by using Zebrafish Genome Array (Affymetrix) according to manufacturer's instruction.
