There are numerous forkhead transcription factors in mammalian cells but we know little about the molecular functions of the majority of these. FOXK2 is a ubiquitously expressed family member suggesting an important function across multiple cell types. Here, we show that FOXK2 binds to the SIN3A and PR-DUB complexes. The PR-DUB complex contains the(More)
CONTEXT Cortisol is released in ultradian pulses. The biological relevance of the resulting fluctuating cortisol concentration has not been explored. OBJECTIVE Determination of the biological consequences of ultradian cortisol pulsatility. DESIGN A novel flow through cell culture system was developed to deliver ultradian pulsed or continuous cortisol to(More)
BACKGROUND The transcription factor FOXM1 is an important regulator of the cell cycle through controlling periodic gene expression during the G2 and M phases. One key target for FOXM1 is the gene encoding the protein kinase PLK1 and PLK1 itself acts in a positive feedback loop to phosphorylate and activate FOXM1. Both FOXM1 and PLK1 have been shown to be(More)
The mammalian genome is transcribed into large numbers of long noncoding RNAs (lncRNAs), but the definition of functional lncRNA groups has proven difficult, partly due to their low sequence conservation and lack of identified shared properties. Here we consider positional conservation across mammalian genomes as an indicator of functional commonality. We(More)
After publication of this study [1], we discovered that we had unintentionally omitted to include an accession number for our ChIP-seq data. The ChIP-seq data for FOXM1 in OE33 cells is available at ArrayExpress; accession number E-MTAB-4121. In addition, we omitted to include lists of the high confidence and high coverage FOXM1 binding regions. This has(More)
Survival rates for oesophageal adenocarcinoma (OAC) remain disappointingly poor and current conventional treatment modalities have minimal impact on long-term survival. This is partly due to a lack of understanding of the molecular changes that occur in this disease. Previous studies have indicated that the transcription factor FOXM1 is commonly upregulated(More)
Gastric cancers present late in life with advanced disease and carry a poor prognosis. Polo-like Kinase 1 (PLK1) is a mitotic kinase with regulatory functions during G2/M and mitosis in the cell cycle. In mammalian cells, there is an intricate co-regulatory relationship between PLK1 and the forkhead transcription factor FOXM1. It has been demonstrated that(More)
Analyzing protein-RNA binding structures depends on a significant quantity of manual work. Therefore, the protein-RNA binding structures are generally studied individually or on a small-scale. The task of analyzing the protein-RNA binding structures manually becomes increasingly difficult as the complexity and number of protein-RNA binding structures(More)
