Autophagy regulates rRNA synthesis
Autophagy has emerged as a key regulator of cell metabolism. Recently, we have demonstrated that autophagy is involved in RNA metabolism by regulating ribosomal RNA (rRNA) synthesis.

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

Recognition of Ribosomal RNA Sites in DNA, I. Analysis of the E. coli System [PDF]
The evidence recently presented of specific hybridization between bacterial ribosomal RNA and homologous DNA1-3 has indicated the possibility of a biochemical approach to the problem of the identification of ribosomal RNA sites in DNA.

Dielectrophoretic manipulation of ribosomal RNA [PDF]
The manipulation of ribosomal RNA (rRNA) extracted from E. coli cells by dielectrophoresis (DEP) has been demonstrated over the range of 3 kHz–50 MHz using interdigitated microelectrodes. Quantitative measurement using total internal reflection fluorescence microscopy of the time dependent collection indicated a positive DEP response characterized by a

Conformational switches control early maturation of the eukaryotic small ribosomal subunit
Eukaryotic ribosome biogenesis is initiated with the transcription of pre-ribosomal RNA at the 5’ external transcribed spacer, which directs the early association of assembly factors but is absent from the mature ribosome.

Loss of the ribosomal RNA methyltransferase NSUN5 impairs global protein synthesis and normal growth
Modifications of ribosomal RNA expand the nucleotide repertoire and thereby contribute to ribosome heterogeneity and translational regulation of gene expression.

Recent Advances on the Structure and Function of RNA Acetyltransferase Kre33/NAT10
Ribosome biogenesis is one of the most energy demanding processes in the cell. In eukaryotes, the main steps of this process occur in the nucleolus and include pre-ribosomal RNA (pre-rRNA) processing, post-transcriptional modifications, and assembly of ...

Variant ribosomal RNA alleles are conserved and exhibit tissue-specific expression
Ribosomal RNA sequence variants are conserved, exhibit tissue-specific expression, and are found in actively translating ribosomes. The ribosome, the integration point for protein synthesis in the cell, is conventionally considered a homogeneous ...

The European ribosomal RNA database [PDF]
The European ribosomal RNA database aims to compile all complete or nearly complete ribosomal RNA sequences from both the small (SSU) and large (LSU) ribosomal subunits. All sequences are available in aligned format. Sequence alignment is based on the secondary structure of the molecules, as determined by comparative sequence analysis.

Arabidopsis AGO1 binds both microRNA (miRNA) and endogenous small interfering RNA (siRNA). Here the authors show that 5′−3′ RNA degradation suppresses siRNA biogenesis from ribosomal RNA to prevent overloading of AGO1 with ribosomal siRNA and maintain ...
