Ribosome profiling reveals novel regulation of GGGGCC repeat-containing RNA translation

, 2021
GGGGCC (G4C2) repeat expansion in the first intron of C9ORF72 causes amyotrophic lateral sclerosis and frontotemporal dementia. Repeat-containing RNA is translated into dipeptide repeat (DPR) proteins, some of which are neurotoxic. Using dynamic ribosome

A metal ion orients SARS-CoV-2 mRNA to ensure accurate 2′-O methylation of its first nucleotide

Nature Communications, 2021
The SARS-CoV-2 nsp16/nsp10 enzyme complex methylates the 2′-OH of the first nucleotide of the viral mRNA, converting the Cap-0 to Cap-1, which helps the virus to evade immune surveillance in the host cell.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

Kissing interaction between 3' noncoding and coding sequences is essential for porcine arterivirus RNA replication

, 2002
We used an infectious cDNA clone of Porcine reproductive and respiratory syndrome virus (PRRSV) to investigate the presence of essential replication elements in the region of the genome encoding the structural proteins.

Evaluation of RNA Amplification Methods to Improve DC Immunotherapy Antigen Presentation and Immune Response

Molecular Therapy: Nucleic Acids, 2013
Dendritic cells (DCs) transfected with total amplified tumor cell RNA have the potential to induce broad antitumor immune responses. However, analytical methods required for quantitatively assessing the integrity, fidelity, and functionality of the ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Influenza A virus preferentially snatches noncoding RNA caps

, 2016
Influenza A virus (IAV) lacks the enzyme for adding 5' caps to its RNAs and snatches the 5' ends of host capped RNAs to prime transcription. Neither the preference of the host RNA sequences snatched nor the effect of cap-snatching on host processes is ...

Whole-Transcriptome Sequencing Reveals That mRNA and ncRNA Levels Correlate with Pleurotus cornucopiae Color Formation

Horticulturae
Pleurotus cornucopiae cap color is an important commercial trait. The roles of non-coding RNA molecules (ncRNAs) in fungal fruiting body color formation are unclear. Whole-transcriptome analyses were performed, identifying messenger RNA (mRNA) and ncRNA (
