NAMPT improves high-fat diet-induced nonalcoholic fatty liver disease (NAFLD) via the SIRT1-C/EBPβ-STEAP4-NRF2 axis.
Article in Journal of molecular cell biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a prevalent chronic condition, yet therapeutic targets remain elusive. Nicotinamide phosphoribosyl transferase (NAMPT) and six-transmembrane epithelial antigen of the prostate 4 (STEAP4) are integral regulators in various metabolic disorders. This study investigates the role and molecular mechanisms of NAMPT in NAFLD pathogenesis. We found that inhibiting NAMPT or silent information regulator 1 (SIRT1) exacerbates liver steatosis and impairs hepatic antioxidant defenses in high-fat diet (HFD)-induced obese mice, while reducing STEAP4 expression in liver tissues, suggesting that NAMPT and SIRT1 are pivotal in NAFLD progression and may regulate STEAP4. The role of NAMPT in SIRT1 expression involves nicotinamide adenine dinucleotide synthesis. Our results indicate that inhibiting SIRT1's deacetylase activity impairs CCAAT/enhancer-binding protein β (C/EBPβ) deacetylation and consequently its function. Additionally, STEAP4, previously identified as a C/EBPβ target, can upregulate the expression and nuclear translocation of NF-E2-related factor 2 (NRF2) to combat oxidative stress in NAFLD. This study confirms that NAMPT ameliorates NAFLD via the SIRT1-C/EBPβ-STEAP4-NRF2 signaling axis in HFD-induced obese mice, proposing a novel strategy for the prevention and treatment of NAFLD.
