Advanced Raman spectroscopy detection of oxidative damage in nucleic acid bases: probing chemical changes and intermolecular interactions in guanosine at ultralow concentration [PDF]

open access: yes, 2021
DNA/RNA synthesis precursors are especially vulnerable to damage induced by reactive oxygen species occurring following oxidative stress. Guanosine triphosphates are the prevalent oxidized nucleosites, which can be misincorporated during replication, leading to mutations and cell death. Here, we present a novel method based on micro-Raman spectroscopy,

Selective phosphodiesterase-5 inhibition reduces neointimal hyperplasia in rat carotid arteries after surgical endarterectomy. [PDF]

open access: yes, 2009
OBJECTIVE: Long-term results of surgical vessel reconstruction are compromised by restenosis caused by neointimal hyperplasia. Recent studies suggest that reduced cyclic guanosine monophosphate signaling is associated with neointima formation.

Initiation of cytosolic plant purine nucleotide catabolism involves a monospecific xanthosine monophosphate phosphatase [PDF]

open access: yes, 2021
In plants, guanosine monophosphate (GMP) is synthesized from adenosine monophosphate via inosine monophosphate and xanthosine monophosphate (XMP) in the cytosol.

Vericiguat: A New Hope for Heart Failure Patients

open access: yesCardiovascular Therapeutics, 2022
Heart failure with reduced ejection fraction (HFrEF) is the inability of the heart to adequately contract or eject blood. This heart is unable to produce adequate cardiac output to perfuse vital tissues.

Cyclic nucleotide specificity of the activator and catalytic sites of a cGMP-stimulated cGMP phosphodiesterase from Dictyostelium discoideum [PDF]

open access: yes, 1985
The cellular slime mold Dictyostelium discoideum has an intracellular phosphodiesterase which specifically hydrolyzes cGMP. The enzyme is activated by low cGMP concentrations, and is involved in the reduction of chemoattractant-mediated elevations of ...

Prevention of quality characteristic decline in freeze‐thawed cultured large yellow croaker (Larimichthys crocea) using flammulina velutipes polysaccharide

open access: yesFood Science &Nutrition, Volume 11, Issue 1, Page 181-190, January 2023., 2023
Our project aims to reveal the cryoprotective effect of flammulina velutipes polysaccharide (FVP) on the quality characteristics in freeze‐thawed cultured large yellow croaker. The differences were compared with conventional commercial cryoprotectant in combination with muscle quality, body color, and flavor.

Photoactivation of trans diamine platinum complexes in aqueous solution and effect on reactivity towards nucleotides [PDF]

open access: yes, 2010
We show that UVA irradiation (365 nm) of the Pt-IV complex trans,trans,trans-[(PtCl2)-Cl-IV(OH)(2)(dimethylamine) (isopropylamine)] (1), induces reduction to Pt-II photoproducts.

G-Quadruplex Guanosine Gels and Single Walled Carbon Nanotubes

open access: yesMolecules, 2013
Solubilization of single walled carbon nanotubes (SWNTs) in aqueous gel phases formed by reversible, G-quadruplex self-assembly of guanosine monophosphate (GMP) alone or with guanosine (Guo) is described.

Hepatitis B Virus Evasion From Cyclic Guanosine Monophosphate–Adenosine Monophosphate Synthase Sensing in Human Hepatocytes

open access: yesHepatology, 2018
Chronic hepatitis B virus (HBV) infection is a major cause of chronic liver disease and cancer worldwide. The mechanisms of viral genome sensing and the evasion of innate immune responses by HBV infection are still poorly understood. Recently, the cyclic
