Yeast RNase III triggers polyadenylation-independent transcription termination [PDF]

open access: yes, 2009
Transcription termination of messenger RNA (mRNA) is normally achieved by polyadenylation followed by Rat1p-dependent 5'-3' exoribonuleolytic degradation of the downstream transcript.

Small Nucleolar RNAs: Biological Functions and Diseases

open access: yesMedComm, Volume 6, Issue 7, July 2025.
The majority of snoRNAs are derived from the intron region of genes, besides to intronic snoRNAs, some snoRNAs are transcribed as independent genes, often by Pol II or III, these snoRNAs are called intergenic snoRNAs. All of these play a role in the occurrence and progression of various diseases through multiple functions.

Conceptual Modeling of mRNA Decay Provokes New Hypotheses [PDF]

open access: yes, 2014
Biologists are required to integrate large amounts of data to construct a working model of the system under investigation. This model is often informal and stored mentally or textually, making it prone to contain undetected inconsistencies, inaccuracies,

Unraveling the Role of Topoisomerase 3β (TOP3B) in mRNA Translation and Human Disease

open access: yesWIREs RNA, Volume 16, Issue 4, July/August 2025.
The human genome encodes six topoisomerases—TOP1, TOP1mt, TOP2A, TOP2B, TOP3A, and TOP3B. The subcellular localization of each is shown. TOP3B, which harbors a bona fide RNA‐binding domain, predominantly localizes to the cytosol and is reported to function in mRNA translation and stability.

Noncoding Subgenomic Flavivirus RNA: Multiple Functions in West Nile Virus Pathogenesis and Modulation of Host Responses

open access: yesViruses, 2014
Flaviviruses are a large group of positive strand RNA viruses transmitted by arthropods that include many human pathogens such as West Nile virus (WNV), Japanese encephalitis virus (JEV), yellow fever virus, dengue virus, and tick-borne encephalitis ...

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

open access: yesFEBS Letters, Volume 599, Issue 9, Page 1222-1235, May 2025.
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 ...

Extracellular Vesicles Alter Trophoblast Function in Pregnancies Complicated by COVID‐19

open access: yesJournal of Extracellular Vesicles, Volume 14, Issue 4, April 2025.
ABSTRACT Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection and resulting coronavirus disease (COVID‐19) cause placental dysfunction, which increases the risk of adverse pregnancy outcomes. While abnormal placental pathology resulting from COVID‐19 is common, direct infection of the placenta is rare.

Genome-wide profiling of uncapped mRNA [PDF]

open access: yes, 2012
Gene transcripts are under extensive posttranscriptional regulation, including the regulation of their stability. A major route for mRNA degradation produces uncapped mRNAs, which can be generated by decapping enzymes, endonucleases, and small RNAs ...

A comprehensive overview on the crosstalk between microRNAs and viral pathogenesis and infection

open access: yesMedicinal Research Reviews, Volume 45, Issue 2, Page 349-425, March 2025.
Abstract Infections caused by viruses as the smallest infectious agents, pose a major threat to global public health. Viral infections utilize different host mechanisms to facilitate their own propagation and pathogenesis. MicroRNAs (miRNAs), as small noncoding RNA molecules, play important regulatory roles in different diseases, including viral ...

Cytoplasmic RNA decay pathways - enzymes and mechanisms [PDF]

open access: yes, 2016
RNA decay plays a crucial role in post-transcriptional regulation of gene expression. Work conducted over the last decades has defined the major mRNA decay pathways, as well as enzymes and their cofactors responsible for these processes. In contrast, our
