C
grade
Phage anti-defense genes targeting NAD<sup>+</sup> metabolism and DNA replication are associated with a broad host range against <i>Klebsiella pneumoniae</i>.
NAD+ (Nicotinamide Adenine Dinucleotide) · Virulence · 2026 · Observational · Preclinical
The study identifies key genetic factors that could help engineer phages with a broader host range against Klebsiella pneumoniae, but further research is needed to confirm these findings in humans.
Not reported in abstract.
D
grade
Efficacy of tannins as silage additives to inhibit deamination process during ensiling: a meta-analysis and <i>in silico</i> approach.
NAD+ (Nicotinamide Adenine Dinucleotide) · Veterinary and animal science · 2026 · Meta-analysis
Tannins show promise in reducing protein degradation during ensiling, but further experimental validation is needed to confirm their practical benefits.
Tannin supplementation significantly reduced NH₃-N, NPN, and soluble nitrogen concentrations (p < 0.001).
C
grade
Evaluation of the safety and potential genotoxicity of a high-purity mogroside ingredient containing siamenoside I produced from a modified strain of &lt;i&gt;Yarrowia lipolytica&lt;/i&gt;.
NAD+ (Nicotinamide Adenine Dinucleotide) · Toxicology reports · 2026 · Animal study · Preclinical
The high-purity mogroside ingredient appears safe in rats, with no genotoxic effects observed at high doses. Human studies are needed for confirmation.
NOAEL of 50,000 ppm in male rats (3309 mg/kg-bw/day) and female rats (3362 mg/kg-bw/day) in 90-day study.
C
grade
Improved catalytic efficiency of P450 OleP for converting lithocholic acid into murideoxycholic and ursodeoxycholic acids through semi-rational and rational design.
NAD+ (Nicotinamide Adenine Dinucleotide) · Synthetic and systems biotechnology · 2026 · In vitro · Preclinical
Engineered P450 OleP mutants show enhanced catalytic efficiency for synthesizing therapeutic bile acids from lithocholic acid, but further research is needed to assess industrial applicability.
MDCA conversion rate improved from 32.5% to 98.3% with S240A mutant.
D
grade
Transancestral TWAS Enrichment of NMN- Informed Pathways in Type 2 Diabetes: CPT2- Linked Fatty-Acid Oxidation and MAP2K1/MAPK3 Drivers as Translational Bridges
NAD+ (Nicotinamide Adenine Dinucleotide) · biorxiv-preprint · 2026 · Observational
This study highlights significant genetic associations between NAD+ precursors and type 2 diabetes across different ancestry groups, particularly noting a strong signal in the European population.
Stouffer Z = −9.70 for fatty-acid-degradation association in the European group, permutation p = 0.0077.
