Complexities associated with expression of Epstein-Barr virus (EBV) lytic origins of DNA replication. [PDF]

, 2007
EBV has two lytic origins (oriLyt) of DNA replication lying at divergent sites on the viral genome within a duplicated sequence (DS). The latter contains potential hairpin loops, ‘hinge’ elements and the promoters for transcripts from viral genes BHLF1 ...

Endonucleolytic cleavages by RNase E generate the mature 3′ termini of the three proline tRNAs in Escherichia coli

Nucleic Acids Research, 2016
We demonstrate here for the first time that proline tRNA 3′ end maturation in Escherichia coli employs a one-step endonucleolytic pathway that does not involve any of the six 3′ → 5′ exonucleases (RNase T, RNase PH, RNase D, RNase BN, RNase II and ...

Impact of Nanoparticle Stiffness on Endosomal Escape and Signaling Pathways in Cytosolic Delivery

Advanced Healthcare Materials, EarlyView.
Nanoparticle (NP) stiffness affects cellular uptake, but its impact on intracellular distribution remains unclear. This study synthesizes silica nanocapsules with varying stiffness, inspired by viral mechanisms, and applies assays to measure cellular uptake and escape efficiency.

Identification of antisense nucleic acid hybridization sites in mRNA molecules with self-quenching fluorescent reporter molecules [PDF]

, 2005
We describe a physical mRNA mapping strategy employing fluorescent self-quenching reporter molecules (SQRMs) that facilitates the identification of mRNA sequence accessible for hybridization with antisense nucleic acids in vitro and in vivo, real time ...

Suppressing t(4;11) Acute Leukemia by Lipopolymer Nanoparticle Delivery of siRNA Targeting KMT2A::AFF1 with Enhanced Extrahepatic Delivery

Advanced Healthcare Materials, EarlyView.
This study introduces a new lipopolymer nanoparticle (LPNP) system that efficiently delivers siRNA to leukemia cells. The LPNPs silence the leukemia fusion gene KMT2A::AFF1, induce apoptosis, and decrease leukemia burden in mice. These results demonstrate the potential of LPNPs as a targeted siRNA therapy for acute lymphoblastic leukemia.

Comparison of methods for quantitation of radioactivity in protected hybrids in RNase protection assays.

BioTechniques, 1998
Several methods exist for the detection and quantitation of RNA, including Northern analysis, in situ hybridization, solution hybridization/RNase protection, dot blot and reverse transcriptase polymerase chain reaction (RT-PCR), and each has unique ...

Porous Decellularized Nerve Grafts Facilitate Recellularization and Nerve Regeneration in a Rat Model of Critical Long‐Gap Peripheral Nerve Injury

Advanced Healthcare Materials, EarlyView.
A decellularized nerve graft (DNG) is modified to generate a porous DNG (PDNG). The PDNG is used to repair a 30‐mm peripheral nerve injury (PNI) defect, and is compared with isograft, serving as the standard, and DNG, a widely used alternative. The result shows that PDNG facilitated nerve regeneration in long‐gap PNI, evidenced by better‐aligned axonal

Mechanical Reinforced and Self‐healing Hydrogels: Bioprinted Biomimetic Methacrylated Collagen Peptide‐Xanthan Gum Constructs for Ligament Regeneration

Advanced Healthcare Materials, EarlyView.
Readily UV‐curing and self‐healing methacrylated collagen peptide (COPMA) hydrogels are developed with tunable mechanical properties. As the interpenetrating network between COPMA and xanthan gum (XG), COPMA‐XG bioinks show improved mechanical properties, printability, and stability, compared to COPMA or XG.

Structure-guided design of endosomolytic chloroquine-like lipid nanoparticles for mRNA delivery and genome editing

Nature Communications
Despite remarkable progress in designing RNA delivery systems, endosomal escape remains a recognized challenge for efficient RNA delivery. In this study, we develop a robust mRNA delivery platform termed endosomolytic chloroquine-like optimized lipid ...
