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 ...

Comparative analysis of pyrosequencing and a phylogenetic microarray for exploring microbial community structures in the human distal intestine [PDF]

, 2009
BACKGROUND: Variations in the composition of the human intestinal microbiota are linked to diverse health conditions. High-throughput molecular technologies have recently elucidated microbial community structure at much higher resolution than was ...

Differentiation of lactococci by rRNA gene restriction analysis [PDF]

FEMS Microbiology Letters, 1991
Strains of the subspecies of Lactococcus lactis could be differentiated by rRNA gene restriction fragment length polymorphisms (RFLP). 16S rRNA-specific oligonucleotide as well as polynucleotide DNA probes were used for the detection of restriction fragments. In addition, a site-specific probe was designed for the intergenic spacer region of 23S and 5S

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 ...

A yeast transcription system for the 5S rRNA gene

Nucleic Acids Research, 1982
A cell-free extract of yeast nuclei that can specifically transcribe cloned yeast 5S rRNA genes has been developed. Optima for transcription of 5S rDNA were determined and conditions of extract preparation leading to reproducible activities and specificities established. The major in vitro product has the same size and oligonucleotide composition as in

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.
