AI Article Synopsis

  • The nuclear cap-binding complex (CBC) plays a vital role in various processes related to mRNA metabolism by binding to the 5' cap of mRNA.
  • The CBP20 subunit of CBC interacts with the mRNA through numerous hydrogen bonds and the stacking of tyrosine sidechains with the first two bases of the capped mRNA.
  • Researchers created an mRNA tetramer using a new capping method, allowing them to study its affinity for CBC through fluorescence titration.

Article Abstract

Binding of mRNA 5' cap by the nuclear cap-binding complex (CBC) is crucial for a wide variety of mRNA metabolic events. The interaction involving the CBP20 subunit of CBC is mediated by numerous hydrogen bonds and by stacking of the tyrosine sidechains with two first bases of the capped mRNA. To examine a possible role of a longer mRNA chain in the CBC-cap recognition, we have synthesized an mRNA tetramer using a novel way of capping an RNA trimer and determined its affinity for CBC by fluorescence titration.

Intervertebral disc degeneration (IDD)-induced lower back pain (LBP) brings heavy burden worldwide. In the degenerated intervertebral disc, there is an increase in the accumulation of reactive oxygen species (ROS) and the infiltration of M1 macrophages, which leads to abnormal local inflammatory microenvironment and exacerbates IDD. In this study, we developed a novel injectable polyethylene glycol (PEG)-capped cerium ion-manganese ion (Ce-Mn) bimetallic nanozyme (CeMn-PEG) with strong ROS scavenging and M2-type macrophage polarizing abilities to efficiently alleviate IDD.

Stearic acid-capped mesoporous silica microparticles as novel needle-like-structured drug delivery carriers.

Eur J Pharm Biopharm

December 2024

School of Pharmacy, College of Health and Life Sciences, Aston University, Birmingham, United Kingdom. Electronic address:

Mesoporous silica are widely utilised as drug carriers due to their large pore volume and surface area, which facilitate effective loading. Additionally, they can be used to enhance drugs stability and protect against enzymatic degradation due to their silica framework. However, without the addition of a capping material, the loaded cargo may be prematurely released before reaching the target site.

This study introduces a novel one-pot strategy for the chemical valorization of poly(lactic acid) (PLA), coupling its base-catalyzed depolymerization with the ring-opening polymerization (ROP) of trimethylene carbonate (TMC). The process exploits an eutectic mixture of lactide (LA) and TMC, which lowers the thermal input required for PLA degradation. Using potassium aryloxide (KOArtBu) as a bifunctional catalyst, the PLA is first quickly hydrolyzed into oligomers or lactic acid, which subsequently initiate the slower polymerization of TMC.

Diazepam (DZP) is a muscle-relaxing, anxiety-relieving sedative drug; nonetheless, it is also an addictive drug that may be abused. This work reports on the development of a novel electrochemical nanosensor for diazepam using SiO-encapsulated-3-mercaptopropionic acid-capped AuZnCeSeS quantum dots (QDs) overcoated with a molecularly imprinted polymer (MIP) on screen-printed carbon electrodes (SPCEs). Electrochemical, spectroscopic and electron microscopic characterization of the nanomaterial and modified electrode surface was carried out and is reported herein.

Surfactin lipopeptides (LPs) are a compelling class of biosurfactants with notable antimicrobial and anticancer properties. This study presents a novel approach by integrating bioinformatics tools to assess the drug potential of Surfactin, specifically focusing on its antibacterial, antifungal activities, and cancer cell-line toxicity. Silver nanoparticles (AgNPs) were synthesized using Surfactin, a biosurfactant derived from KLP2016, as a capping agent, both in the presence and absence of Surfactin, to evaluate its impact on nanoparticle stability and bioactivity.
