On the nucleolar size and density in human early granulocytic progenitors, myeloblasts
European Journal of Histochemistry, 2009 Human myeloblasts were studied in bone marrow of patients suffering from chronic phase of chronic myeloid leukaemia to provide more information on the nucleolar diameter in these early granulocytic progenitors. These cells are a convenient model for such

Glutamine deficiency in solid tumor cells confers resistance to ribosomal RNA synthesis inhibitors
Nature Communications, 2022 Small molecules that target RNA Polymerase I inhibit ribosome biogenesis to activate p53 through the nucleolar surveillance response pathway. Here, the authors show that p53 induction by ribosome stress is dependent on extracellular glutamine ...

Functional organization of box C/D RNA-guided RNA methyltransferase [PDF]
, 2020 Box C/D RNA protein complexes (RNPs) catalyze site-specific 2'-O-methylation of RNA with specificity determined by guide RNAs. In eukaryotic C/D RNP, the paralogous Nop58 and Nop56 proteins specifically associate with terminal C/D and internal C'/D ...

Nucleolar localization signals of Box H/ACA small nucleolar RNAs [PDF]
The EMBO Journal, 1999 The two major families of small nucleolar RNAs (snoRNAs), Box C/D and Box H/ACA, are generated in the nucleoplasm and transported to the nucleolus where they function in rRNA processing and modification. We have investigated the sequences involved in the intranuclear transport of Box H/ACA snoRNAs by assaying the localization of injected fluorescent ...

Expression and Functional Studies on the Noncoding RNA, PRINS. [PDF]
, 2012 PRINS, a noncoding RNA identified earlier by our research group, contributes to psoriasis susceptibility and cellular stress response. We have now studied the cellular and histological distribution of PRINS by using in situ hybridization and demonstrated

Evolution of small nucleolar RNAs in nematodes [PDF]
Nucleic Acids Research, 2006 In contrast to mRNAs, which are templates for translating proteins, non-protein coding (npc) RNAs (also known as 'non-coding' RNA, ncRNA), exhibit various functions in different compartments and developmental stages of the cell. Small nucleolar RNAs (snoRNAs), one of the largest classes of npcRNAs, guide post-transcriptional modifications of other RNAs

Jouvence a small nucleolar RNA required in the gut extends lifespan in Drosophila
Nature Communications, 2020 Small non-coding RNAs contribute to the regulation of aging. Here the authors identify a small nucleolar RNA, the snoRNA jouvence, which extends the lifespan of fruit flies through its function in the gut, and is conserved in humans.

Yeast Rrp8p, a novel methyltransferase responsible for m1A 645 base modification of 25S rRNA [PDF]
, 2012 Ribosomal RNA undergoes various modifications to optimize ribosomal structure and expand the topological potential of RNA. The most common nucleotide modifications in ribosomal RNA (rRNA) are pseudouridylations and 2'-O methylations (Nm), performed by H ...

Human snoRNA-93 is processed into a microRNA-like RNA that promotes breast cancer cell invasion
npj Breast Cancer, 2017 RNA: Small nucleolar-derived RNA contributes to tumor invasiveness A short microRNA-like fragment excised from a small nucleolar RNA (called a snoRNA-derived RNA or sdRNA) contributes to the invasiveness of breast cancer cells.
