Perturbation of Spermine Homoeostasis Uncouples Hypersensitive Cell Death From Systemic Plant Immunity

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Polyamines are key regulators of plant stress responses, yet their contribution to coordinating local immune responses with systemic immunity remains poorly understood. Here, we investigated how spermine (Spm) homeostasis influences local and systemic defence responses in Arabidopsis thaliana following inoculation with Pseudomonas syringae pv.

Effects of Hypoxanthine Substitution in Peptide Nucleic Acids Targeting KRAS2 Oncogenic mRNA Molecules: Theory and Experiment

open access: yes, 2016
Genetic disorders can arise from single base substitutions in a single gene. A single base substitution for wild type guanine in the twelfth codon of KRAS2 mRNA occurs frequently to initiate lung, pancreatic, and colon cancer.

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

sox17 Mutagenesis Reveals Compounding Effects ofMaternal and Zygotic Contribution on Microglia Abundance

open access: yesGlia, Volume 75, Issue 1, January 2027.
sox17 is a maternal effect gene impacting microglia and microglia precursor abundance. sox17 mRNA injection timed to maternal contribution rescues abundance. A CRISPR screen reveals f11r.1, gas6, and mpp1 also regulate microglia abundance. ABSTRACT Embryonic development is shaped by maternal and zygotic factors but how the interplay between these ...

Formation of hypoxanthine from guanine in rat liver extracts

open access: yes, 1961
The formation of hypoxanthine from guanine in extracts of rat liver has been observed and its mechanism investigated. Evidence is presented indicating that the reduction occurs at the free base level, the pathway involving deamination to xanthine ...

The development and critical evaluation of an immunoassay for hypoxanthine in biological matrices. [PDF]

open access: yes, 2018
A classical radioimmunoassay for hypoxanthine was developed and validated. Hypoxanthine, being a low molecular weight compound (M.W. 136.11) is not immunogenic unless first attached to a macromolecule such as a protein.

7-(2'-Deoxy-?-D-ribofuranosyl)hypoxanthine [PDF]

open access: yes, 1996
The [alpha]-configured N7 analogue of 2'-deoxyinosine [7-(2'-deoxy-[alpha]-D-ribofuranosyl)hypoxanthine, C10H12N4O4] shows the following structural characteristics: (i) the furanose part of the molecule adopts the 2'-endo conformation [pseudorotation ...

Disruption of Lactate Metabolism in the Peripheral Nervous System Leads to Motor‐Selective Deficits

open access: yesGlia, Volume 74, Issue 12, December 2026.
To test the importance of lactate metabolism and shuttling between Schwann cells and neurons in the PNS, we selectively knocked out both LDHA and LDHB in motor neurons, sensory neurons, or Schwann cells. ABSTRACT Schwann cells (SCs) myelinate and provide trophic support to axons in the peripheral nervous system (PNS).

Adenosine and hypoxanthine transport in horse erythrocytes: Evidence for a polymorphism in the transport of hypoxanthine via a sodium-dependent cotransporter

open access: yes, 1998
The inward transport of two purines, adenosine and hypoxanthine, at 37 degrees C by horse erythrocytes was compared. No mediated transport of adenosine was detected in horse erythrocytes, nor was saturable, high-affinity binding of the potent facilitated-
