The Gene Expression Omnibus (GEO, is an international public repository for high-throughput microarray and next-generation sequence functional genomic data sets submitted by the research community. The resource supports archiving of raw data, processed data and metadata which are indexed, cross-linked and searchable. All(More)
The Gene Expression Omnibus (GEO) repository at the National Center for Biotechnology Information (NCBI) archives and freely disseminates microarray and other forms of high-throughput data generated by the scientific community. The database has a minimum information about a microarray experiment (MIAME)-compliant infrastructure that captures fully annotated(More)
The Gene Expression Omnibus (GEO) at the National Center for Biotechnology Information (NCBI) is the largest public repository for high-throughput gene expression data. Additionally, GEO hosts other categories of high-throughput functional genomic data, including those that examine genome copy number variations, chromatin structure, methylation status and(More)
A decade ago, the Gene Expression Omnibus (GEO) database was established at the National Center for Biotechnology Information (NCBI). The original objective of GEO was to serve as a public repository for high-throughput gene expression data generated mostly by microarray technology. However, the research community quickly applied microarrays to(More)
In Saccharomyces cerevisiae, genes located at the telomeres and the HM loci are subject to transcriptional silencing. Here, we report results of screening a Gal4 DNA-binding domain hybrid library for proteins that cause silencing when targeted to a silencer-defective HMR locus.
Until recently, little was known about how transforming growth factor (TGF)-beta signals are transduced to the nucleus. With the discovery of the Smad proteins initially in Drosophila and C. elegans, the unraveling of the pathway has begun. Nine different vertebrate members also have been reported, indicating that Smads are a conserved component of the(More)
Several studies have demonstrated the existence of an autonomous intranuclear phospho-inositide cycle that involves the activation of nuclear PI-PLC and the generation of diacylglycerol (DG) within the nucleus. Although several distinct isozymes of PI-PLC have been detected in the nucleus, the isoform that has been most consistently highlighted as being(More)
Selection for mutants which release glucose repression of the CYB2 gene was used to identify genes which regulate repression of mitochondrial biogenesis. We have identified two of these as the previously described GRR1/CAT80 and ROX3 genes. Mutations in these genes not only release glucose repression of CYB2 but also generally release respiration of the(More)
The TBX20 data set [4] provides ChIP-Seq and RNA-Seq data. In here only the RNA-Seq part of the data is utilized. The raw data where downloaded from Gene Expression Omnibus (GEO) [1], accession number GSM767225GSM767230. TBX20 (T-box 20) in general is a transcriptional regulator essential for cardiac development and maintenance of mouse heart tissue. In(More)
