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 ...

The 18S rRNA genes of Haemoproteus (Haemosporida, Apicomplexa) parasites from European songbirds with remarks on improved parasite diagnostics

Malaria Journal, 2023
Background The nuclear ribosomal RNA genes of Plasmodium parasites are assumed to evolve according to a birth-and-death model with new variants originating by duplication and others becoming deleted.

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

FEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

Pre-sequencing assessment of RNA-Seq library quality using real-time qPCR

BioTechniques
RNA sequencing (RNA-Seq) is an essential assay for studying transcriptome profiling. Ribosomal RNA (rRNA) comprises more than 80–90% of total cellular RNA; efficient removal is essential for accurately capturing transcriptomes, particularly to sequence ...

Variation of expression levels of seven housekeeping genes at different life-history stages in Porphyra yezoensis. [PDF]

PLoS ONE, 2013
In order to identify the optimal internal control for relative real-time PCR when studying target gene expression in the red alga Porphyra yezoensis, we quantified the expression of seven housekeeping genes (18S ribosomal RNA, 30S ribosomal protein S8 ...

Sequence determination of the 3' terminal T1 oligonucleotide of 18S ribosomal RNA

Nucleic Acids Research, 1976
We have reexamined the primary structure of the 3' terminal oligonucleotide of 18S RNA from chicken fibroblasts and have shown, contrary to previously published results that this extremity G-A-U-C-A-U-U-AOH is identical to that of the rabbit, drosophila and bombyx.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

H/ACA snR30 snoRNP guides independent 18S rRNA subdomain formation

Nature Communications
Ribosome biogenesis follows a cascade of pre-rRNA folding and processing steps, coordinated with ribosomal protein incorporation. Nucleolar 90S pre-ribosomes are well-described stable intermediates, composed of pre-18S rRNA, ribosomal S-proteins, U3 ...

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA

FEBS Open Bio, EarlyView.
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

In Situ Detection of Aspergillus 18S Ribosomal RNA in Invasive Pulmonary Apergillosis.

Internal Medicine, 1999
We attempted to evaluate the usefulness of in situ hybridization (ISH) in the specific diagnosis of Aspergillus pulmonary infection.We used an ISH technique using a multiple digoxigenin-incorporating probe, which was constructed by means of the polymerase chain reaction (PCR) from the 18S ribosomal RNA of Aspergillus fumigatus.We studied twelve ...
