Origins of DNA replication are generally inefficient, with most firing in fewer than half of cell cycles. However, neither the mechanism nor the importance of the regulation of origin efficiency is clear. In fission yeast, origin firing is stochastic, leading us to hypothesize that origin inefficiency and stochasticity are the result of a diffusible, rate-limiting activator. We show that the Hsk1-Dfp1 replication kinase (the fission yeast Cdc7-Dbf4 homologue) plays such a role. Increasing or dec ...[more]

S. pombe oxidative stress response time course

Project description:S. pombe cells were challenged with 0.5 mM hydrogen peroxide for various periods of time (0, 10, 30, 60, 120, 180 minutes). Total RNA was isolated at each time point, labeled with Cy3 and hybridized on cDNA microarrays competitively with Cy5 labeled RNA pooled from all 6 samples. A biological replicate was performed in analyzed as a dyw swap (pool = Cy3, time series = Cy5).

Repression of meiotic genes by antisense transcription and by Fkh2 transcription factor in Schizosaccharomyces pombe

Project description:In S. pombe, about 5% of genes are meiosis-specific and accumulate little or no mRNA during vegetative growth. Here we use Affymetrix tiling arrays to characterize transcripts in vegetative and meiotic cells. In vegetative cells, many meiotic genes, especially those induced in mid-meiosis, have abundant antisense transcripts. These results suggest that antisense transcription represses sense transcription of meiotic genes in vegetative cells. Although the mechanism(s) of antisense mediated transcription repression need to be further explored, our data indicates that RNAi machinery, such as Rdp1, is not required for repression. Previously, we and others used non-strand specific methods to study splicing regulation of meiotic genes and concluded that 28 mid-meiotic genes are spliced only in meiosis. We now demonstrate that the “unspliced” signal in vegetative cells comes from the antisense RNA, not from unspliced sense RNA, andwe argue against the idea that splicing regulates these mid-meiotic genes. Most of these mid-meiotic genes are induced in mid-meiosis by the forkhead transcription factor Mei4. Interestingly, deletion of a different forkhead transcription factor, Fkh2, allows low levels of sense expression of some mid-meiotic genes in vegetative cells. We propose that expression of mid-meiotic genes is kept tightly off in vegetative cells by two independent ways: antisense transcription and Fkh2 repression.

Transcription profiling of human colon cancer cell line SW480 expressing ERb and then treated with estrogen or untreated

Project description:Assess the full impact of estrogen receptor beta on transcription by a full transcriptome analysis of ERb-mediated gene regulation in the SW480 colon cancer cell line. The colon cancer cell line SW480 does not express endogenous ER but is made ERb-expressing by lentiviral transduction of an ERb expression cassette. Introduction of ERb makes it possible to study the role and function of ERb in colon cancer as well as the impact ERb has on its own (in the absence of ERa).
