Pseudouridylation of yeast ribosomal precursor RNA

Nucleic Acids Research, 1979
The pseudouridylation of ribosomal RNA of Saccharomyces carlsbergensis was investigated with respect to its timing during the maturation of rRNA and its sequence specificity. Analysis of 37-S RNA, the common precursor to 17-S, 5.8-S and 26-S rRNA and most probably the primary ribosomal transcript, shows that this RNA molecule contains already most if ...

Attachment of the RNA degradosome to the bacterial inner cytoplasmic membrane prevents wasteful degradation of rRNA in ribosome assembly intermediates.

PLoS Biology, 2023
RNA processing and degradation shape the transcriptome by generating stable molecules that are necessary for translation (rRNA and tRNA) and by facilitating the turnover of mRNA, which is necessary for the posttranscriptional control of gene expression ...

Understanding the Effects of Trenbolone Acetate, Polyamine Precursors, and Polyamines on Proliferation, Protein Synthesis Rates, and the Abundance of Genes Involved in Myoblast Growth, Polyamine Biosynthesis, and Protein Synthesis in Murine Myoblasts

Biology, 2023
Research suggests that androgens increase skeletal muscle growth by modulating polyamine biosynthesis. As such, the objective of this study was to investigate effects of anabolic hormones, polyamine precursors, and polyamines relative to proliferation ...

Structural basis of RNA polymerase I pre-initiation complex formation and promoter melting

Nature Communications, 2020
RNA polymerase I (Pol I) catalyses the transcription of ribosomal RNA precursors, and its transcription initiation mechanism differs from that of Pol II and Pol III.

Stability and Precursor Relationships of Virus RNA

Journal of General Virology, 1972
Summary Pulse-chase experiments with [3H]-uridine were performed with glucosamine-treated chick cells infected by RNA viruses. It was established that in cells infected by fowl plague virus both virus RNA and the RNA with the complementary base sequence were metabolically stable.

ATF4 Regulates MYB to Increase γ-Globin in Response to Loss of β-Globin

Cell Reports, 2020
Summary: β-Hemoglobinopathies can trigger rapid production of red blood cells in a process known as stress erythropoiesis. Cellular stress prompts differentiating erythroid precursors to express high levels of fetal γ-globin.

The Genesis of Human Breast Cancer: Histological, Histochemical and Cariometric Studies: Proposition on the Genesis of Cancer

Revista Brasileira de Cancerologia, 2023
1. Câncer arises gradually, preceded by histological, histochemical and cariometric (tetraploidism) or hyperdiploidism pictures which may be called morphological precursors of câncer. 2.

RNA-binding protein immunoprecipitation as a tool to investigate plant miRNA processing interference by regulatory proteins of diverse origin

Plant Methods, 2018
Background Due to the nature of viral RNA genomes, RNA viruses depend on many RNA-binding proteins (RBP) of viral and host origin for replication, dissemination and evasion of host RNA degradation pathways. Some viruses interfere with the microRNA (miRNA)

Hfq and RNase R Mediate rRNA Processing and Degradation in a Novel RNA Quality Control Process

mBio, 2020
RNA quality control pathways are critical for cell survival. Here, we describe a new surveillance process involved in the degradation of highly structured and stable ribosomal RNAs.

Structural determinants of Arabidopsis thaliana Hyponastic leaves 1 function in vivo. [PDF]

PLoS ONE, 2014
MicroRNAs have turned out to be important regulators of gene expression. These molecules originate from longer transcripts that are processed by ribonuclease III (RNAse III) enzymes. Dicer proteins are essential RNAse III enzymes that are involved in the
