(Submitter supplied) 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. more...

(Submitter supplied) Accumulating evidence indicate that aberrantly increased ribosome biogenesis is a hallmark of cancer. As such, there is a growing interest in the development of strategies to target this pathway for cancer therapeutic. It is well established that inhibition of any steps of ribosome biogenesis induces a nucleolar stress characterized by p53 activation and subsequent cell cycle arrest and/or cell death. more...

(Submitter supplied) Myriad of craniofacial disorders are caused by heterozygous mutations in general regulators of housekeeping cellular functions such as ribosome biogenesis. While it is understood that many of these highly tissue-specific malformations are a consequence of defects in cranial neural crest cells (cNCCs), an embryonic cell group that gives rise to most of the facial structures during embryogenesis, the mechanism underlying cell type-selectivity of these effects remains largely unknown. more...

(Submitter supplied) In our work, we uncovered a critical role for cholesterol homeostasis in terminal erythropoiesis. The master transcriptional factor GATA1 binds to Sterol-regulatory element binding protein 2 (SREBP2) to downregulate cholesterol biosynthesis, leading to a gradual reduction in intracellular cholesterol levels. To reveal genetic interactions and epistatic relations between GATA1 and SREBP2 on depth at the whole genome level, we performed RNA sequencing to analyze the gene expression profiles change between treated with Vehicle or β-estradiol in overexpressing active SREBP2 G1E-ER4 cells.

(Submitter supplied) In our work, we explored the dynamics of cholesterol homeostasis during terminal erythropoiesis. Interestingly, we found differential requirements of cholesterol during terminal erythropoiesis, with that cholesterol is essential for the early stage erythroblasts proliferation, while the downregulation of cholesterol biosynthesis is required for late stage cell cycle exit and final enucleation. To reveal the role of cholesterol in the the early stage erythroblasts proliferation and the detail mechanisms of erythroblasts late stage cell cycle exit, we performed RNA sequencing to analyze the gene expression profiles change between untreated and cholesterol treated erythroblasts.

(Submitter supplied) 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). more...

(Submitter supplied) Erythropoiesis is a tightly regulated process. Development of red blood cells occurs through differentiation of hematopoietic stem cells into more committed progenitors and finally into erythrocytes. Binding of erythropoietin to its receptor (EpoR) is strictly required for erythropoiesis as it promotes survival and late maturation of erythroid progenitors. In vivo and in vitro studies have highlighted the requirement of EpoR signaling through Jak2 tyrosine-kinase and Stat5a/b as a central pathway. more...

(Submitter supplied) Regulation of the cell cycle is intimately linked to erythroid differentiation, yet how these processes are coupled is not well understood. To gain insight into this coordinate regulation, we examined the role that the retinoblastoma protein (Rb), a central regulator of the cell cycle, plays in erythropoiesis. We found that Rb serves a cell-intrinsic role and its absence causes ineffective erythropoiesis, with a differentiation block at the transition from early to late erythroblasts. more...

(Submitter supplied) Suture mesenchymal stem cell (MSC) drives calvarial suture development, homeostasis, and regeneration. Its loss leads to craniosynostosis, a prevailing craniofacial disorder characterized by premature suture closure. Ribosome biogenesis, historically thought to be a static house-keeping process, is now known to have tissue-specific roles. However, the functional specificity of ribosome biogenesis in suture MSCs remains largely unexplored, hampering development of therapeutic strategies for craniofacial tissue regeneration. more...

(Submitter supplied) The eukaryotic RNA exosome is a ubiquitously expressed complex of nine core proteins (EXOSC1-9) and associated nucleases responsible for RNA processing and degradation. Autosomal recessive mutations in EXOSC3, EXOSC8, EXOSC9 and the exosome cofactor RBM7 cause pontocerebellar hypoplasia and motor neuronopathy. To understand the importance of the exosome in neurodegeneration, we investigated the consequences of exosome mutations on RNA metabolism and cellular survival in zebrafish and human cell models. more...

(Submitter supplied) In ribosomopathies, perturbed expression of ribosome components leads to tissue-specific phenotypes. What accounts for such tissue-selective manifestations as a result of mutations in the ribosome, a ubiquitous cellular machine, has remained a mystery. Combining mouse genetics and in vivo ribosome profiling, we observe limb patterning phenotypes in ribosomal protein (RP) haploinsufficient embryos and uncover selective translational changes of transcripts controlling limb development. more...
