The genome and proteome of the Kluyvera bacteriophage Kvp1 – another member of the T7-like Autographivirinae [PDF]

, 2008
BACKGROUND: Kluyvera, a genus within the family Enterobacteriaceae, is an infrequent cause of human infections. Bacteriophage Kvp1, the only bacteriophage isolated for one of its species, Kluyvera cryocrescens, is a member of the viral family Podoviridae.

Stimulation of ribosomal frameshifting by antisense LNA

Nucleic Acids Research, 2010
Abstract Programmed ribosomal frameshifting is a translational recoding mechanism commonly used by RNA viruses to express two or more proteins from a single mRNA at a fixed ratio. An essential element in this process is the presence of an RNA secondary structure, such as a pseudoknot or a hairpin, located downstream of the slippery ...

Mutation type‐specific transcriptomic signatures and readthrough therapy rescue in SMC1A‐related developmental and epileptic encephalopathy

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to investigate the molecular consequences of pathogenic variants in the SMC1A gene—particularly those associated with developmental and epileptic encephalopathy (DEE85)—and to evaluate the therapeutic potential of ataluren in restoring SMC1A function and mitigating disease‐related transcriptomic and genomic ...

Direct measurement of the mechanical work during translocation by the ribosome. [PDF]

, 2014
A detailed understanding of tRNA/mRNA translocation requires measurement of the forces generated by the ribosome during this movement. Such measurements have so far remained elusive and, thus, little is known about the relation between force and ...

A Data‐Driven Redefinition of Early Relapse in Pediatric T Cell Acute Lymphoblastic Leukemia: Evidence for Progression of Disease 15 Months

Med Research, EarlyView.
Data‐driven redefinition of early relapse in pediatric T‐ALL using hazard modeling, cumulative incidence, and time‐dependent HR across 1533 patients in three independent cohorts identifies 15 months as the optimal threshold. By integrating temporal risk metrics and external validation, this study provides evidence for POD ≤ 15 months as a data‐driven ...

Genome-wide CRISPR screens identify noncanonical translation factor eIF2A as an enhancer of SARS-CoV-2 programmed −1 ribosomal frameshifting

Cell Reports, 2023
Summary: Many positive-strand RNA viruses, including all known coronaviruses, employ programmed −1 ribosomal frameshifting (−1 PRF) to regulate the translation of polycistronic viral RNAs.

V, 2.Ribosomal frameshifting in astroviruses

, 2003
This chapter reviews ribosomal frameshifting with an emphasis on the frameshifting process in astroviruses. Frameshifting is a potential antiviral target. It is possible that the replication cycle of any virus that uses this process could be disrupted by modulation of frameshift efficiencies, but a better understanding of the occurrence and the ...

Influence of the relA gene on ribosome frameshifting [PDF]

Molecular Genetics and Genomics, 2002
We have examined the influence of genotype at the relA locus on the kinetics of leftward (or -1) frameshifting at a variety of codons calling for a limiting aminoacyl-tRNA species. We used lacZ left-frameshift reporter constructs carrying the sequenceU UUC XYZ, whereXYZ was each of three triplets coding for three different amino acids; we slowed the ...

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

An Overlapping Protein-Coding Region in Influenza A Virus Segment 3 Modulates the Host Response [PDF]

, 2012
Influenza A virus (IAV) infection leads to variable and imperfectly understood pathogenicity. We report that segment 3 of the virus contains a second open reading frame (‘X-ORF’), accessed via ribosomal frameshifting. The frameshift product, termed PA-X,
