Termination region in rRNA genes from a eucaryotic thermophile, Thermomyces lanuginosus.

Abstract:

:S1 mapping of the termination region in the ribosomal DNA from a thermophilic fungus, Thermomyces lanuginosus, revealed three distinct termini corresponding to the mature 25S rRNA, a precursor that is 19 nucleotides longer and corresponds to the 37S precursor in yeast cells, and a putative termination site at +96 that bears a limited sequence homology with the SalI box of mammalian cells. An estimate of the secondary structure suggested that the three termini are in close proximity, a feature that may be essential to precursor termination and maturation. The results raise questions regarding recently reported relationships between ribosomal DNA termination and spacer enhancer elements in fungi.

  • The hypoxia-inducible factor 1/NOR-1 axis regulates the survival response of endothelial cells to hypoxia.

    abstract::Hypoxia induces apoptosis but also triggers adaptive mechanisms to ensure cell survival. Here we show that the prosurvival effects of hypoxia-inducible factor 1 (HIF-1) in endothelial cells are mediated by neuron-derived orphan receptor 1 (NOR-1). The overexpression of NOR-1 decreased the rate of endothelial cells und...
