Bacterial Community Reconstruction Using A Single Sequencing Reaction [PDF]

, 2010
Bacteria are the unseen majority on our planet, with millions of species and comprising most of the living protoplasm. While current methods enable in-depth study of a small number of communities, a simple tool for breadth studies of bacterial population

Mouse nucleolus-like body supports transcription and enhances processing of rRNA in porcine enucleolated oocytes

Macedonian Veterinary Review
Fully-grown mammalian oocytes contain morphologically evident but transcriptionally inactive nucleoli called “nucleolus-like bodies” (NLBs). These nuclear structures are essential for early embryonic development.

The molecular basis for ANE syndrome revealed by the large ribosomal subunit processome interactome

eLife, 2016
ANE syndrome is a ribosomopathy caused by a mutation in an RNA recognition motif of RBM28, a nucleolar protein conserved to yeast (Nop4). While patients with ANE syndrome have fewer mature ribosomes, it is unclear how this mutation disrupts ribosome ...

Identification of RMP24 and RMP64, human ribonuclease MRP-specific protein components

Cell Reports
Summary: Human RNase MRP is a ribonucleoprotein (RNP) enzyme that processes precursor rRNA (pre-rRNA) at ITS1 site 2 and may have additional activities. It is an endonuclease related to RNase P, which processes pre-tRNAs and pre-tRNA-like substrates.

Tor1 and CK2 kinases control a switch between alternative ribosome biogenesis pathways in a growth-dependent manner.

PLoS Biology, 2017
Ribosome biogenesis is a major energy-consuming process in the cell that has to be rapidly down-regulated in response to stress or nutrient depletion. The target of rapamycin 1 (Tor1) pathway regulates synthesis of ribosomal RNA (rRNA) at the level of ...

Nucleolar Structure and Function in Trypanosomatid Protozoa

Cells, 2019
The nucleolus is the conspicuous nuclear body where ribosomal RNA genes are transcribed by RNA polymerase I, pre-ribosomal RNA is processed, and ribosomal subunits are assembled.

RiboCop surveils pre-rRNA processing by Dicer in cellular quiescence

Abstract In nature, most cells exist in a quiescent G 0 state in which cellular homeostasis must be rigorously maintained in the absence of cell division. Non-coding RNAs are prevalent in G 0 and are important regulators of development and ...

N-TERMINAL PROCESSING OF RIBOSOMAL PROTEIN L27 IN STAPHYLOCOCCUS AUREUS [PDF]

, 2012
The bacterial ribosome is essential to cell growth yet little is known about how its proteins attain their mature structures. Recent studies indicate that certain Staphlyococcus aureus bacteriophage protein sequences contain specific sites that may be ...

Bacteriological and epidemiological studies of campylobacter spp. in Swedish broilers [PDF]

, 2007
Campylobacter jejuni is the most frequently reported cause of bacterial gastrointestinal illness in humans in Sweden. Chicken products are considered an important risk factor for human infection.
