Project description:DNA replication checkpiont kinase rad3 (human ATM/ATR-like kinase) and cds1 (human CHK2-like kinase) are known to restore stalled replication forks and prevent subsequent cell cycle progression during a replication block imposed by HU-treatment in fission yeast. In order to identify cell cycle-specific exression which are modulated by replication checkpoint kinase rad3 and cds1, microarray approach was used to profile asynchronous and synchronous cells of wildtype and mutants treated and untreated with HU Keywords: HU treated cells vs wildtype untreated cells

Project description:Expression profiles of polg mutant cells reveal that many genes encoding proteins involved in cell wall biogenesis and stress response are induced, suggesting that polg mutant cells attempt to maintain growth potential and undergo extensive oxidative metabolism. Conversely, many genes encoding proteins involved in ribosome biogenesis and respiration are repressed, indicating that cells depleted of mtDNA are adapted to grow slowly in absence of mitochondrial function.

Project description:DNA replication is initiated at multiple sites or origins enriched with AT-rich sequences at various times during the S-phase. While current studies of genome-wide DNA replication profiles have focused on the timing of replication and the location of origins, the efficiency of replication/firing at various origins remains unclear. In this study, we show different efficiencies of DNA replication at various loci by using ORF-specific DNA microarrays. DNA copy-number increases as a function of time at individual loci are approximated to near-sigmoidal models for estimation of replication initiation and completion timings in HU-challenged cells. Duplicating times (from initiation to completion) vary from loci to loci, partly contributing to various firing efficiencies at origins. DNA replication timing profiles are strikingly similar to the reported patterns of enriched ssDNA, suggesting that majority stalled forks are restored for resumption of DNA replication. Although the DNA replication timing profiles are disrupted in HU-challenged cds1? cells, ~85% of potential origins overlapped with those found in wild type cells, significantly, most of which represents inefficiently fired origins in wild type cells. Together, our result indicates that replication checkpoint plays a role in monitoring efficient origins and thus maintaining global DNA replication patterns in HU-challenged cells.
