AI Article Synopsis
Article Abstract
The synthesis, computer modeling, and biological activity of an octawalled molecular umbrella short interfacing RNA (siRNA) conjugate is described. This molecular umbrella-siRNA conjugate exhibited mRNA knockdown activity in vitro in the absence of a transfection reagent. Evaluation of this molecular umbrella conjugate in vivo, using the rat eye via intravitreal injection, resulted in sequence specific mRNA knockdown in the retina with no obvious signs of toxicity, as judged by ophthalmic examination.

Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by extracellular amyloid plaques, predominantly consisting of amyloid- (A) peptides. The oligomeric form of A is acknowledged as the most neurotoxic, propelling the pathological progression of AD. Interestingly, besides A, other proteins are co-localized within amyloid plaques.

Gaussia Luciferase (GLuc) is a renowned reporter protein that can catalyze the oxidation of coelenterazine (CTZ) and emit a bright light signal. GLuc comprises two consecutive repeats that form the enzyme body and a central putative catalytic cavity. However, deleting the C-terminal repeat only limited reduces the activity (over 30% residual luminescence intensity detectable), despite being a key part of the cavity.

EgB4 is a nanobody that could facilitate the development of drug-nanobody conjugates or drug delivery in cancer treatment due to its specific binding ability to the EGFR transmembrane protein. More significantly, EgB4 does not hamper the EGFR function and associates with EGFR in both the presence and absence of an EGF ligand. However, the difference in EgB4-EGFR interaction with and without EGF ligand is not clear.

Deep eutectic solvents (DESs) have emerged as promising solvents for biocatalysis. While their impact on enzyme solvation and stabilization has been studied for several enzyme classes, their role in substrate binding is yet to be investigated. Herein, molecular dynamics (MD) simulations of horse-liver alcohol dehydrogenase (HLADH) are performed in choline chloride-ethylene glycol (ChCl-EG) and choline chloride-glycerol (ChCl-Gly) at varying water concentrations.
