Identification of the modifications in artificial E. coli rRNAs

ABSTRACT: Ribosome biogenesis is pivotal in the self-replication of life. In Escherichia coli, three ribosomal RNAs and 54 ribosomal proteins are synthesized and subjected to cooperative hierarchical assembly facilitated by numerous accessory factors. Realizing ribosome biogenesis in vitro is a critical milestone for understanding the self-replication of life and creating artificial cells. Despite its importance, this goal has not yet been achieved owing to its complexity. In this study, we report the successful realization of ribosome biogenesis in vitro. Specifically, we developed a highly specific and sensitive reporter assay for the detection of nascent ribosomes. The reporter assay allowed for combinatorial and iterative exploration of reaction conditions for ribosome biogenesis, leading to the simultaneous, autonomous synthesis of both small and large subunits of ribosomes in vitro through transcription, translation, processing, and assembly in a single reaction space. Our achievement represents a crucial advancement toward revealing the fundamental principles underlying the self-replication of life and creating artificial cells.

The E3 SUMO ligase Mms21 controls ribosome biogenesis

Project description:The budding yeast E3 SUMO ligase Mms21, a component of the Smc5-6 complex, regulates sister chromatid cohesion, DNA replication, and DNA repair. We identify a role for Mms21 in ribosome biogenesis. The mms21RINGD mutant exhibits reduced rRNA production, nuclear accumulation of 60S and 40S ribosomal proteins, and elevated Gcn4 translation. Genes involved in ribosome biogenesis and translation are down-regulated in the mms21RINGD mutant.

Small molecule RBI2 disrupts ribosome biogenesis through pre-rRNA depletion

Project description: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 relationship, only recently has ribosome biogenesis drawn interest as a cancer therapeutic target. Here, we have exploited the relationship between ribosome biogenesis and cancer cell proliferation by using a potent ribosome biogenesis inhibitor: RBI2 (Ribosome Biogenesis Inhibitor 2) to perturb cancer cell growth and viability. We demonstrate that RBI2 significantly decreases cell viability in malignant melanoma cells and breast cancer cell lines. Treatment with RBI2 dramatically and rapidly decreases ribosomal RNA (rRNA) synthesis, without affecting the occupancy of RNA polymerase I (Pol I) on the ribosomal DNA template. Next-generation RNA sequencing (RNA-seq) reveals that RBI2 and previously described ribosome biogenesis inhibitor CX-5461 induce distinct changes in the transcriptome. Investigation of the content of the pre-rRNAs through RT-qPCR reveals an increase in polyadenylation of cellular rRNA after treatment with RBI2, a known pathway by which rRNA degradation occurs. Northern blotting revealed that RBI2 does not appear to impair or alter rRNA processing. Collectively, these data suggest that RBI2 inhibits rRNA synthesis distinctly from other previously described ribosome biogenesis inhibitors, potentially through a novel pathway that upregulates turnover of premature rRNAs.

Runx1 deficiency decreases ribosome biogenesis and confers stress resistance to hematopoietic stem and progenitor cells

Project description: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) have a slow growth, low biosynthetic, small cell phenotype and markedly reduced ribosome biogenesis (Ribi). The reduced Ribi involves decreased levels of rRNA and many mRNAs encoding ribosome proteins. Runx1 appears to directly regulate Ribi; Runx1 is enriched on the promoters of genes encoding ribosome proteins, and binds the ribosomal DNA repeats. Runx1 deficient HSPCs have lower p53 levels, reduced apoptosis, an attenuated unfolded protein response, and accordingly are resistant to genotoxic and endoplasmic reticulum stress. The low biosynthetic activity and corresponding stress resistance provides a selective advantage to Runx1 deficient HSPCs, allowing them to expand in the bone marrow and outcompete normal HSPCs. Comparison of the phenotypic and molecular properties of normal (Runx1f/f, or WT) versus Runx1 deficient (Mut) hematopoietic stem cells.

Genome-wide reporter screen for transcriptional regulators of ribosome biogenesis genes and ribosomal protein genes

Project description:A genome-wide CRISPR/Cas9 knockout reporter screen was performed to identify transcriptional regulators of ribosomal biogenesis genes and ribosomal protein genes. The murine GeCKO v2 library provided by the Zhang lab was amplified and positive control sgRNAs targeting the reporters were spiked-in. NIH/3T3 cells (murine fibroblasts) harboring the "ribosome biogenesis" reporter Fbl-GFP (Fibrillarin promoter-driven enhanced GFP fused to the PEST domain of the murine ornithine decarboxylase) and the "ribosomal protein" reporter Rpl18-RFP (Rpl18 promoter-driven TurboRFP fused to the PEST domain of the murine ornithine decarboxylase) were transduced with the aforementioned library, selected and FACS-sorted six days after infection. The sorted conditions were i) low GFP, but middle to strong RFP expression (RiBi down); ii) low RFP, but middle to strong GFP expression (RP down); iii) low GFP and low RFP expression (Both down); iv) strong GFP and strong RFP expression (Both up). The same amount of cells that were used for sorting, were harvested as the "unsorted" condition to which all sorted samples were compared to. The plasmid library was also sequenced.

RNA helicase DDX10 is Required for Pluripotency of Stem Cells by Regulating 18S rRNA Processing (RNA-Seq)

Project description:Ribosomes, as a protein synthesis machine, are required for stem cells to maintain self-renewal. Here, we find that DEAD-box RNA helicase DDX10 is necessary for cellular pluripotency acquisition in somatic cell reprogramming, and in mouse embryonic stem cells (mESCs), DDX10 degradation disrupts cellular homeostasis, leads to cell cycle arrest in G1 phase and markedly inhibits cell proliferation. DDX10 is localized in dense fiber component (DFC) and granular component (GC), mainly binds to 45S ribosomal RNA (rRNA) and participates in regulating ribosome biogenesis. Specifically, DDX10 degradation prevents the release of U3 snoRNA from pre-rRNA, and disrupts pre-rRNA processing and maturation of 18S rRNA, leading to impaired ribosomal small subunit production. Together, this study reveals that DDX10 functions as an important regulator of ribosome biogenesis, and is essential for the survival, induction and maintenance of pluripotent stem cells.

p53 activation during ribosome biogenesis regulates normal erythroid differentiation. [ChIP-Seq]

Project description:The role of ribosome biogenesis in erythroid development is supported by the recognition of erythroid defects in ribosomopathies in both Diamond-Blackfan anemia and 5q- syndrome. Whether ribosome biogenesis exerts a regulatory function on normal erythroid development is still unknown. In the present study, a detailed characterization of ribosome biogenesis dynamics during human and murine erythropoiesis shows that ribosome biogenesis is abruptly interrupted by the drop of rDNA transcription and the collapse of ribosomal protein neo-synthesis. Its premature arrest by RNA polI inhibitor, CX-5461 targets the proliferation of immature erythroblasts. We also show that p53 is activated spontaneously or in response to CX-5461 concomitantly to ribosome biogenesis arrest, and drives a transcriptional program in which genes involved in cell cycle arrest, negative regulation of apoptosis and DNA damage response were upregulated. RNA polI transcriptional stress results in nucleolar disruption and activation of ATR-CHK1-p53 pathway. Our results imply that the timing of ribosome biogenesis extinction and p53 activation are crucial for erythroid development. In ribosomopathies in which ribosome availability is altered by unbalanced production of ribosomal proteins, the threshold of ribosome biogenesis down-regulation could be prematurely reached and together with pathological p53 activation prevents a normal expansion of erythroid progenitors.
