Autophagy regulates rRNA synthesis
Nucleus, 2022 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.

PLoS ONE, 2009 BackgroundRibosomal RNA (rRNA) is a central regulator of cell growth and may control cancer development. A cis noncoding rRNA (nc-rRNA) upstream from the 45S rRNA transcription start site has recently been implicated in control of rRNA transcription in ...

Circularization of 23S rRNA but not 16S rRNA within archaeal ribosomes
Genome BiologyBackground Processing of archaeal 16S and 23S rRNAs is believed to involve excision of individual rRNAs from polycistronic precursors, circularization of excised rRNAs, and re-linearization before the incorporation into ribosomes.

Organelle-associated rRNA Degradation [PDF]
Bio-Protocol, 2019 Cytosolic rRNAs are highly dynamic and can be degraded under conditions such as apoptosis, starvation and magnesium depletion. The degradation is also related to their specific localization, as fractions of cytosolic ribosomes are localized on the ...

Simultaneous measurement of 16S-rRNA and pre-16S-rRNA as a strategy to monitor clinical tuberculosis [PDF]
Frontiers in AntibioticsBackgroundCulture-based biomarkers of TB treatment response monitoring, e.g., Mycobacterial Growth Indicatory Tube (MGIT), are compromised when bacteria enter a non-replicating persister phase limiting the measurement of antibiotic efficacy and ...
