TranscriptomicsRunx1 deficiency decreases ribosome biogenesis and confers stress resistance to hematopoietic stem and progenitor cells
The transcription factor RUNX1 is frequently mutated in myelodysplastic syndrome and leukemia. RUNX1 mutations can be early events, creating pre-leukemic stem cells that expand in the bone marrow. Here we show that, counter-intuitively, Runx1 deficient hematopoietic stem and progenitor cells (HSPCs)...

GenomicsSch9 regulates ribosome biogenesis via Stb3, Dot6 and Tod6 and the histone deacetylase complex RPD3L (ChIP-Seq data)
TORC1 is a structurally and functionally conserved multiprotein complex that regulates many aspects of eukaryote growth including the synthesis and assembly of ribosomes. The protein kinase activity of this complex is responsive to environmental cues and is potently inhibited by the natural product ...

TranscriptomicsUBF Is An Epigenetic Factor Required For Ribosomal RNA Gene Activity And Preinitiation Complex Assembly But Not For Nucleolar Body Formation
Upstream Binding Factor (UBF) is a unique multi-HMGB-box protein first identified as a co-factor in RNA polymerase I (RPI/PolI) transcription. However, its poor DNA sequence selectivity and its ability to generate nucleosome-like nucleoprotein complexes suggest a more generalized role in chromatin s...

TranscriptomicsCircular non-coding RNA ANRIL modulates ribosomal RNA maturation and atherosclerosis in humans.
Circular RNAs (circRNAs) are broadly expressed in eukaryotic cells, but their role in human health and disease remains obscure. Here, we show that circular antisense non-coding RNA in the INK4 locus (circANRIL), which is transcribed at a locus of atherosclerotic cardiovascular disease on chromosome ...

TranscriptomicsSIRT7-dependent deacetylation of the U3-55k protein controls pre-rRNA processing [CLIP-Seq]
SIRT7 is an NAD+-dependent protein deacetylase with important roles in ribosome biogenesis and cell proliferation. Previous studies have established that SIRT7 is associated with RNA polymerase I, interacts with pre-rRNA and promotes rRNA synthesis. Here we show that SIRT7 is also associated with sn...

ProteomicsNuclear VCP-like 2 (NVL2)-associated complex
LC-MSMS analysis of NVL2-associated pre-60S complex. To obtain more insights into the molecular mechanism of this effects caused by the mutant NVL2 in pre-60S complexes,we searched for additional proteins that preferentially interact with the NVL2(E365Q/E682Q) in comparison with wild-type NVL2. Co-m...

TranscriptomicsSmall molecule RBI2 disrupts ribosome biogenesis through pre-rRNA depletion
In all domains of life, the rate of protein synthesis is directly linked to the rates of cell growth and proliferation. Consequently, highly proliferative cancer cells are especially sensitive to perturbations in ribosome biogenesis. While ribosome synthesis and cancer have a well-established relati...

ProteomicsRole of the sarcin-ricin loop of 23S rRNA in biogenesis of the 50S ribosomal subunit
In this work, we show that 23S rRNA lacking the SRL can be efficiently reconstituted into 50S subunits, which exhibit full peptidyl transferase (PT) activity. Using cryo-EM and proteomic methods, we also further characterize affinity-purified SRL particles isolated from cells. Collectively, these da...
