Phylogenetic analysis of microbial communities in different regions of the gastrointestinal tract in Panaque nigrolineatus, a wood-eating fish [PDF]

, 2012
The Neotropical detritivorous catfish Panaque nigrolineatus imbibes large quantities of wood as part of its diet. Due to the interest in cellulose, hemi-cellulose and lignin degradation pathways, this organism provides an interesting model system for the

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Polyadenylated versions of small non-coding RNAs in Saccharomyces cerevisiae are degraded by Rrp6p/Rrp47p independent of the core nuclear exosome

Microbial Cell
In Saccharomyces cerevisiae, polyadenylated forms of mature (and not precur-sor) small non-coding RNAs (sncRNAs) those fail to undergo proper 3-end mat-uration are subject to an active degradation by Rrp6p and Rrp47p, which does not require the ...

The conformation of ribosomes and rRNA

Current Opinion in Structural Biology, 1997
During the past 18 months, electron microscopists have published two reconstructions of the Escherichia coli ribosome, independently derived from images of unstained particles. The resolutions of their images are 20-25 A-much higher than any previously available. During the same time, NMR spectroscopists have provided an atomic-resolution model for the

Location of 5.8 S rRNA contact sites in 28 S rRNA and the effect of alpha-sarcin on the association of 5.8 S rRNA with 28 S rRNA.

Journal of Biological Chemistry, 1983
We have constructed phage M13mp7 clones each containing the coding strand from one of three restriction fragments which collectively span the mouse 28 S rRNA gene with the exception of the 3'-terminal approximately 500 base pairs. When hybridized to 28 S rRNA, only the fragment containing the 5'-terminal 1400 nucleotides of the gene inhibited the ...

Differential polyadenylation of ribosomal RNA during post-transcriptional processing in Leishmania. [PDF]

, 2005
The protozoan parasite Leishmania belongs to the most ancient eukaryotic lineages and this is reflected in several distinctive biological features, such as eukaryotic polycistronic transcription and RNA trans-splicing.

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Culture medium modulates nucleolar architecture and disrupts ribosomal RNA levels in preimplantation mouse embryos

The Journal of Reproduction and Development
Embryonic culture media support preimplantation development in vitro, yet their broader effects on the molecular organization have not been fully characterized. In mammalian embryos, the nucleolus is a prominent and

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Exploring Fresh Lettuce (Lactuca sativa) as a Dairy-Free Probiotic Source

Journal of Microbiological Sciences
Probiotics are living microorganisms that, when given in appropriate amounts, have optimistic effects on body. This study explores the potential of fresh lettuce (Lactuca sativa) leaves as a probiotic source for individuals with dairy allergies.
