The 5′ → 3′ exoribonuclease XRN1/Pacman and its functions in cellular processes and development
XRN1 is a 5' ? 3' processive exoribonuclease that degrades mRNAs after they have been decapped. It is highly conserved in all eukaryotes, including homologs in Drosophila melanogaster (Pacman), Caenorhabditis elegans (XRN1), and Saccharomyces cerevisiae (

Senescence in placenta/fetal membranes is a normal phenomenon linked to term parturition. However, excessive senescence which may be induced by telomere attrition, has been associated with preeclampsia (PE). We hypothesized that the telomerase complex in

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

(A-D) Insect Cellular mRNA stability is altered by DENV sfRNA. The half-life of ECR (A & B) and La (C&D) mRNA was determined in Aag2 and Aag2-wMel cells mock infected or infected with DENV after Actinomycin-D treatment by RT-qPCR.

RNA structural profiling of Turnip Yellow Mosaic Virus by DMS‐MaPseq and DREEM analyses uncover that viral genome‐wide RSS is highly complicated and heterogeneous, with alternative RSSs widely distributed across the genome. Notably, the viral 3’ tRNA‐like structure adopts alternative conformations in vivo.

Noncoding RNAs and the Architecture of Gene Regulation: Focus on Long and Small Regulatory RNAs
NcRNAs play fundamental roles in many facets of cellular homeostasis, systemic physiology and disease outcomes. Historical and current advancements have led to a deeper understanding of ncRNAs' roles, utilizing their diverse and tissue‐specific functions to drive the development of innovative therapeutic tools.

Decay of mRNAs targeted by RISC requires XRN1, the Ski complex, and the exosome [PDF]
RNA interference (RNAi) is a conserved RNA silencing pathway that leads to sequence-specific mRNA decay in response to the presence of double-stranded RNA (dsRNA). Long dsRNA molecules are first processed by Dicer into 21–22-nucleotide small interfering RNAs (siRNAs).

This study revealed a dose‐dependent miRNA buffering mechanism involving extracellular export and storage of miRNA on lipid droplets. The protein HuR facilitates miRNA buffering by dissociating miRNAs from Ago2 and promoting miRNA accumulation on lipid droplets or its extracellular export, depending on cellular requirements.

We demonstrate that both Hepatitis C virus (HCV) and Bovine Viral Diarrhea virus (BVDV) contain regions in their 5' UTRs that stall and repress the enzymatic activity of the cellular 5'-3' exoribonuclease XRN1, resulting in dramatic changes in the ...
