Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.

Project description:Ubiquitin-mediated proteolysis play a significant role in various biological processes including transcription, DNA repair and cell cycle progression. The identification of Set8 and Set8b (a splice isoform) histone H4K20 methyl transferase as a substrate for the cullin-based ubiquitin ligase (CRL4-Cdt2) demonstrate that this pathway plays a significant role in promoting cell cycle progression, specifically promoting G2 progression. This study investigate the effect of failure to degrade Set8 in S-phase of the cell cycle via CRL4-Cdt2 on gene expression. We used microarrays to detail the effect of the expression of stable form of Set8b H4K20 mono-methyl transferase (Set8b_deltaPIP2) on gene expression Human osteosarcoma-derived human cells were transduced with retroviruses encoding either wt-Set8b or a mutant of Setb8 which is resistant to degradation via CRL4-Cdt2 ubiquitin ligase complex (Set8b_deltaPIP2) or with an a control pMSCV empty virus. 5 days after transduction, cells were harvested and the RNA was extracted by Trizol (Invitrogen) and hybridized to the affymetrix chips array.

Project description:The methylation state of lysine 20 on histone H4 (H4K20) has been linked to cell cycle progression, Origin Recognition Complex (ORC) binding, and replication origin regulation. Monomethylation of H4K20 (H4K20me1) is mediated by the cell cycle-regulated histone methyltransferase PR-Set7, which is essential for genome integrity and cell cycle progression. PR-Set7 depletion in mammalian cells results in defective S-phase progression and the accumulation of DNA damage, which could be partially attributed to a defect in pre-Replication Complex (pre-RC) formation and origin activity. However, these studies were limited to a handful of mammalian origins, and it remains unclear how PR-Set7 and H4K20 methylation impact the replication program on a genomic scale. Using Drosophila Kc167 cells, we employed genetic, cytological, and genomic approaches to better understand the role of PR-Set7 and H4K20 methylation in regulating DNA replication and governing genome stability. We find that depletion of Drosophila PR-Set7 and loss of H4K20me1 result in the accumulation of DNA damage and an ATR-dependent cell cycle arrest. The cell cycle arrest occurs during the second S-phase following loss of PR-Set7 activity, suggesting that accumulation of nascent H4K20 is recalcitrant to the DNA replication program. Deregulation of H4K20 methylation had no impact on origin activation throughout the genome; instead, we found that the DNA damage marker, phosphorylated H2A.v (γ-H2A.v), accumulated specifically in late replicating domains in the absence of PR-Set7. This suggests that the molecular basis for the cell cycle arrest and accumulation of DNA damage resulting from loss of PR-Set7 is stochastic fork collapse within late replicating domains.
