RNA compaction and iterative scanning for small RNA targets by the Hfq chaperone

open access: yesNature Communications
RNA-guided enzymes must quickly search a vast sequence space for their targets. This search is aided by chaperones such as Hfq, a protein that mediates regulation by bacterial small RNAs (sRNAs).

Evolution of the Transfer RNA Molecule Evolution of the Transfer RNA Molecule

open access: yesZeitschrift für Naturforschung C, 1977
Abstract Base sequences of many transfer RNA (tRNA) species obtained from different sources contain homologous regions. These homologies, which are 6 to 20 nucleotides long, occur both within the same tRNA molecule and between many different tRNA molecules repeatedly.

Unconventional mRNA processing and degradation pathways for the polycistronic yrzI (spyTA) mRNA in Bacillus subtilis

open access: yesFEBS Letters, EarlyView.
The S1025 peptide is the major antidote to the YrzI toxin, which we renamed here as SpyT (Small Peptide YrzI Toxin) and SpyA (Small Peptide YrzI Antitoxin) (1). Degradation of the toxin–antitoxin spyTA mRNA, either by a translation‐dependent cleavage by the endoribonuclease Rae1 (2) or by direct attack by 3′‐exoribonucleases (3), also contributes to ...

Transfer RNA comes of age [PDF]

open access: yesRNA, 2015
The year the journal RNA was founded was slated by some in scientific publishing to be the year that one particular type of RNA's run in the spotlight would end. In 1995 I had recently started as a post-doc with Dieter Soll at Yale when he came into the lab to solemnly inform us all that an editor at a certain (S)cience journal had just told him “we ...

The power of microRNA regulation—insights into immunity and metabolism

open access: yesFEBS Letters, EarlyView.
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

Complete chloroplast genome sequence of Chrysosplenium ramosum and Chrysosplenium alternifolium (Saxifragaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete chloroplast genome of Chrysosplenium ramosum Maxim. and Chrysosplenium alternifolium L. were reported in this study. The chloroplast genomes were 153,460 bp for C. ramosum and 152,619 bp for C. alternifolium.

Analysis of Mitochondrial Transfer RNA Mutations in Breast Cancer

open access: yesBalkan Journal of Medical Genetics, 2022
Damage of mitochondrial functions caused by mitochondrial DNA (mtDNA) pathogenic mutations had long been proposed to be involved in breast carcinogenesis. However, the detailed pathological mechanism remained deeply undetermined.

Unlocking the potential of tumor‐derived DNA in urine for cancer detection: methodological challenges and opportunities

open access: yesMolecular Oncology, EarlyView.
Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...

The first mitochondrial genome for the subfamily Asopinae (Heteroptera: Pentatomidae) and its phylogenetic implications

open access: yesMitochondrial DNA. Part B. Resources, 2017
Here, we determined the complete mitogenome of Picromerus griseus, the first for the subfamily Asopinae. This mitochondrial genome contains 16,338 bp, with an A + T content of 71.69%, and contains 37 typical mitochondrial genes (13 protein-coding genes ...

Free Extracellular miRNA Functionally Targets Cells by Transfecting Exosomes from Their Companion Cells. [PDF]

open access: yesPLoS ONE, 2015
Lymph node and spleen cells of mice doubly immunized by epicutaneous and intravenous hapten application produce a suppressive component that inhibits the action of the effector T cells that mediate contact sensitivity reactions.
