HIV-1 uses dynamic capsid pores to import nucleotides and fuel encapsidated DNA synthesis

open access: yesNature, 2016
During the early stages of infection, the HIV-1 capsid protects viral components from cytosolic sensors and nucleases such as cGAS and TREX, respectively, while allowing access to nucleotides for efficient reverse transcription.

The nucleobase analog 4-thiouracil hijacks the pyrimidine salvage pathway to inhibit Staphylococcus aureus growth

open access: yesMicrobiology Spectrum
Staphylococcus aureus is a leading cause of bacterial-induced mortality due to infections that are increasingly resistant to antibiotics, highlighting the need for new therapeutic strategies to treat these drug-resistant infections.

An Allosteric Inhibitory Site Conserved in the Ectodomain of P2X Receptor Channels

open access: yesFrontiers in Cellular Neuroscience, 2019
P2X receptors constitute a gene family of cation channels gated by extracellular ATP. They mediate fast ionotropic purinergic signaling in neurons and non-excitable cell types in vertebrates.

RNAs Containing Modified Nucleotides Fail To Trigger RIG-I Conformational Changes for Innate Immune Signaling

open access: yesmBio, 2016
Invading pathogen nucleic acids are recognized and bound by cytoplasmic (retinoic acid-inducible gene I [RIG-I]-like) and membrane-bound (Toll-like) pattern recognition receptors to activate innate immune signaling.

The 5' untranslated region of the I factor, a long interspersed nuclear element-like retrotransposon of Drosophila melanogaster, contains an internal promoter and sequences that regulate expression [PDF]

open access: yes, 1993
The I-R system of hybrid dysgenesis in Drosophila melanogaster is controlled by a long interspersed nuclear element-like retroposon, the I factor.

Enzyme-free genetic copying of DNA and RNA sequences

open access: yesBeilstein Journal of Organic Chemistry, 2018
The copying of short DNA or RNA sequences in the absence of enzymes is a fascinating reaction that has been studied in the context of prebiotic chemistry.

Physiological and Metabolic Responses of Leymus chinensis Seedlings to Alkali Stress

open access: yesPlants, 2022
To elucidate the physiological and metabolic mechanism of perennial grass responses to alkali stress, we selected Leymus chinensis (L. chinensis), a salt-tolerant perennial rhizomatous species of the family Poaceae as experimental material.

Programmable multimetallic linear nanoassemblies of ruthenium–DNA conjugates [PDF]

open access: yes, 2012
A new ruthenium–DNA conjugates family was synthesized, made up of a ruthenium complex bound to one or two identical DNA strands of 14–58 nucleotides.

Disruption of nucleotide biosynthesis reprograms mitochondrial metabolism to inhibit adipogenesis

open access: yesJournal of Lipid Research
A key organismal response to overnutrition involves the development of new adipocytes through the process of adipogenesis. Preadipocytes sense changes in the systemic nutrient status and metabolites can directly modulate adipogenesis.

Effect of Deep Dormancy Temperature Cultivation on Meat Quality of Crucian Carp (Carassius auratus)

open access: yesFoods, 2023
To extend the survival of crucian carp (Carassius auratus) during transportation, the effect of deep dormancy temperature (DDT) cultivation on the crucian carp was investigated by measuring the respiratory rate, survival time, and effect of cooling speed
