New functions for endoribonuclease III were unravelled in the facultative photosynthetic bacterium Rhodobacter sphaeroides by transcriptome analysis and phenotypic screening under three different growth conditions. The RNase III deficient mutant showed reduced pigmentation, linked to decreased expression of photosynthesis‐related mRNAs (bch and crt ...

A Novel Pathway of Functional microRNA Uptake and Mitochondria Delivery
In the presence of serum, microRNAs (miRNAs) spontaneously form ≈110 nm nanoparticles, mediated bycationic proteins. When depleted, miRNA uptake is blocked. Unlike lysosome‐located, nanoparticle‐delivere mechanism are preferentially delivered to mitochondria of recipient cells by PNPT1.

How hydrolytic exoribonucleases impact human disease: Two sides of the same story
Ribonucleases (or simply RNases) are the enzymes responsible for the processing and degradation of all types of RNAs, having multiple roles in every aspect of RNA metabolism. Here, we review what is known about the involvement of the RNase II/RNB family of 3′–5′ exoribonucleases in human disease.

Adenovirus-mediated hPNPase(old-35) gene transfer as a therapeutic strategy for neuroblastoma [PDF]
Current treatment options for neuroblastoma fail to eradicate the disease in the majority of high-risk patients, clearly mandating development of innovative therapeutic strategies. Gene therapy represents a promising approach for reversing the neoplastic

Summary Mitochondrial biogenesis relies on nuclearly encoded factors, which regulate the expression of the organellar‐encoded genes. Pentatricopeptide repeat (PPR) proteins constitute a major gene family in angiosperms that are pivotal in many aspects of mitochondrial (mt)RNA metabolism (e.g. trimming, splicing, or stability).

Isolate Specific Cold Response of Yersinia enterocolitica in Transcriptional, Proteomic, and Membrane Physiological Changes [PDF]
Yersinia enterocolitica, a zoonotic foodborne pathogen, is able to withstand low temperatures. This psychrotrophic ability allows it to multiply in food stored in refrigerators. However, little is known about the Y. enterocolitica cold response.

Symbiont‐specific responses to environmental cues in a threesome lichen symbiosis
Abstract Photosymbiodemes are a special case of lichen symbiosis where one lichenized fungus engages in symbiosis with two different photosynthetic partners, a cyanobacterium and a green alga, to develop two distinctly looking photomorphs. We compared gene expression of thallus sectors of the photosymbiodeme‐forming lichen Peltigera britannica ...

The endoribonucleolytic N-terminal half of Escherichia coli RNase E is evolutionarily conserved in Synechocystis sp. and other bacteria but not the C-terminal half, which is sufficient for degradosome assembly [PDF]
Escherichia coli RNase E, an essential single-stranded specific endoribonuclease, is required for both ribosomal RNA processing and the rapid degradation of mRNA.
