Perturbation of Ribosome Biogenesis Drives Cells into Senescence through 5S RNP-Mediated p53 Activation

Cell Reports, 2015
The 5S ribonucleoprotein particle (RNP) complex, consisting of RPL11, RPL5, and 5S rRNA, is implicated in p53 regulation under ribotoxic stress. Here, we show that the 5S RNP contributes to p53 activation and promotes cellular senescence in response to ...

Lymphoid and CXCR4 Cell Targeted Lipid Nanoparticles Facilitate HIV‐1 Proviral DNA Excision

Advanced Healthcare Materials, EarlyView.
Advancements in ART improve HIV‐1 patient outcomes but are unable to eliminate latent viral DNA. To address this, CXCR4‐targeted lipid nanoparticles (T‐LNPs) for delivering CRISPR‐Cas9 to excise HIV‐1 DNA in infected cells are developed. These T‐LNPs achieve ≈60% HIV‐1 DNA excision efficacy in blood and splenic tissue, demonstrating promise for ...

SSB-1 of the yeast Saccharomyces cerevisiae is a nucleolar-specific, silver-binding protein that is associated with the snR10 and snR11 small nuclear RNAs [PDF]

, 1990
SSB-1, the yeast single-strand RNA-binding protein, is demonstrated to be a yeast nucleolar-specific, silver-binding protein. In double-label immunofluorescence microscopy experiments antibodies to two other nucleolar proteins, RNA Pol I 190-kD and ...

Molecular Mechanisms of Extracellular Vesicle Biogenesis and Their Impact on the Design of Custom EVs

Advanced Healthcare Materials, EarlyView.
Extracellular vesicles (EVs) are pivotal mediators of intercellular communication and disease, yet the fundamental mechanisms controlling their biogenesis and cargo selection remain unclear. This limitation hinders their diagnostic utility and therapeutic development.

Beyond BLASTing : ribonucleoprotein evolution via structural prediction and ancestral sequence reconstruction [PDF]

, 2016
Primary homology in DNA and protein sequence has long been used to infer a relationship between similar sequences. However gene sequence, and thus protein sequence, can change over time.

Hfq binding changes the structure of Escherichia coli small noncoding RNAs OxyS and RprA, which are involved in the riboregulation of rpoS [PDF]

, 2013
OxyS and RprA are two small noncoding RNAs (sRNAs) that modulate the expression of rpoS, encoding an alternative sigma factor that activates transcription of multiple Escherichia coli stress-response genes. While RprA activates rpoS for translation, OxyS

Development of a Modular Ribonucleoprotein Complex as a General Strategy to Deliver RNAi Therapeutics

Advanced Healthcare Materials, EarlyView.
A modular and customizable RNAi therapeutics delivery platform composed of a pseudosymmetric human RNA binding protein‐siRNA complex (SmiRNP) is developed. By fusing a targeting module and an endosomal escape peptide onto the delivery platform, SmiRNP successfully delivered siRNA to silence the KRAS oncogene in a colorectal carcinoma cell line, leading

Purification and electron cryomicroscopy of coronavirus particles. [PDF]

, 2008
Intact, enveloped coronavirus particles vary widely in size and contour, and are thus refractory to study by traditional structural means such as X-ray crystallography. Electron microscopy (EM) overcomes some problems associated with particle variability
