Mutual Relations between Substituent Effect, Hydrogen Bonding, and Aromaticity in Adenine-Uracil and Adenine-Adenine Base Pairs

Molecules, 2020
The electronic structure of substituted molecules is governed, to a significant extent, by the substituent effect (SE). In this paper, SEs in selected nucleic acid base pairs (Watson-Crick, Hoogsteen, adenine-adenine) are analyzed, with special emphasis ...

Mechanism study on the effect of adenine on the viability of Lactiplantibacillus plantarum LIP-1 powder via freeze-drying

Food Science of Animal Products, 2023
Adenine acts as a growth promoter to promote the growth of the lactic acid bacteria (LAB), but the effect on the viability of freeze-dried strains has rarely been studied.

Metal-ion binding and metal-ion induced folding of the adenine-sensing riboswitch aptamer domain [PDF]

, 2010
Divalent cations are important in the folding and stabilization of complex RNA structures. The adenine-sensing riboswitch controls the expression of mRNAs for proteins involved in purine metabolism by directly sensing intracellular adenine levels ...

Research Models for Studying Vascular Calcification [PDF]

, 2020
Calcification of the vessel wall contributes to high cardiovascular morbidity and mortality. Vascular calcification (VC) is a systemic disease with multifaceted contributing and inhibiting factors in an actively regulated process.

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Surface-Enhanced Raman Spectroscopy (SERS) for Identifying Traces of Adenine in Organic-Bearing Extraterrestrial Dust Analogs Captured in the Tanpopo Aerogel after Hypervelocity Impacts

Gels
Raman spectroscopy is a non-destructive analytical technique for characterizing organic and inorganic materials with spatial resolution in the micrometer range. This makes it a method of choice for space-mission sample characterization, whether on return

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

The effect of adenine adsorption on Zn (II) electroreduction in acetate buffer.

Acta Chimica Slovenica, 2018
The paper presents the thermodynamic analysis of adenine adsorption on a mercury electrode in an acetate buffer at pH 3 and pH 4. Adsorption energy and constants were determined using the Frumkin isotherm and the virial isotherm.

Purine and pyrimidine bases as growth substances for lactic acid bacteria [PDF]

, 1941
In 1936 Richardson (1) showed that uracil was essential for the anaerobic growth of Staphylococcus aureus, but not for aerobic growth of the same organism.

Attenuation of ischemic liver injury by prostaglandin E1 analogue, misoprostol, and prostaglandin I2 analogue, OP-41483 [PDF]

, 1998
Background: Prostaglandin has been reported to have protective effects against liver injury. Use of this agent in clinical settings, however, is limited because of drugrelated side effects.
