Divergent Delivery and Expression Kinetics of Lipid and Polymeric Nanoparticles across mRNA Modalities

open access: yesAdvanced Science, EarlyView.
Self‐amplifying (saRNA), linear (linRNA), and circular (circRNA) mRNAs are compared under standardized conditions using lipid nanoparticles (LNPs) and pABOL polymer. saRNA achieved superior expression, while linRNA and circRNA performance varied based on untranslated region elements and delivery method.

Structural Probing and Molecular Modeling of the A3 Adenosine Receptor: A Focus on Agonist Binding

open access: yesMolecules, 2017
Adenosine is an endogenous modulator exerting its functions through the activation of four adenosine receptor (AR) subtypes, termed A1, A2A, A2B and A3, which belong to the G protein-coupled receptor (GPCR) superfamily.

Synthesis of Nucleoside Phosphate and Phosphonate Prodrugs

open access: yesChemical Reviews, 2014
For many decades, the design of new nucleoside analogs as potential therapeutic agents focused on both sugar and nucleobase modifications. These nucleoside analogs rely on cellular kinases to undergo stepwise addition of phosphate groups to form the ...

Emergence of highly profibrotic and proinflammatory Lrat+Fbln2+ HSC subpopulation in alcoholic hepatitis

open access: yesHepatology, EarlyView., 2022
Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

Dynamic eIF3‐S6 Phase Separation Switch Instructed by m6A Modification Drives the Molting of Locusts

open access: yesAdvanced Science, EarlyView.
This research reveals that reduced m6A modifications during insect molting trigger liquid–liquid phase separation (LLPS) of the m6A reader eIF3‐S6, which binds and stabilizes key molting mRNAs, including EcR and Cht10. Disrupting m6A or LLPS causes cuticle remodeling defects and molting failure, highlighting the synergistic control of gene expression ...

Nucleotides: Structure and Properties [PDF]

open access: yes, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

Nucleoside transporter proteins as biomarkers of drug responsiveness and drug targets

open access: yesFrontiers in Pharmacology, 2015
Nucleoside and nucleobase analogs are currently used in the treatment of solid tumors, lymphoproliferative diseases, viral infections such as hepatitis and AIDS, and some inflammatory diseases such as Crohn. Two gene families are implicated in the uptake

The cumulative analgesic effect of repeated electroacupuncture is modulated by Adora3 in the SCDH of mice with neuropathic pain

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Neuropathic pain management via repeated electroacupuncture. Abstract Background Existing remedial approaches for relieving neuropathic pain (NPP) are challenging and open the way for alternative therapeutic measures such as electroacupuncture (EA). The mechanism underlying the antinociceptive effects of repeated EA sessions, particularly concerning ...

Effect of uridine protecting groups on the diastereoselectivity of uridine-derived aldehyde 5’-alkynylation

open access: yesBeilstein Journal of Organic Chemistry, 2017
The 5’-alkynylation of uridine-derived aldehydes is described. The addition of alkynyl Grignard reagents on the carbonyl group is significantly influenced by the 2’,3’-di-O-protecting groups (R1): O-alkyl groups led to modest diastereoselectivities (65 ...
