Anti-Oxidative and Anti-Inflammatory Effect of Protaetia Brevitarsis-Derived Protein Hydrolysates in Adipose Tissues of Obese Mice.
Article in International journal of molecular sciences, 2025. 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
Obesity is a major global health issue linked to metabolic disorders, chronic inflammation, and systemic complications, with high-fat diets (HFDs) playing a key role by disrupting intestinal balance and promoting oxidative stress. This study investigates Protaetia brevitarsis-derived protein hydrolysate (PBPH), an insect-derived bioactive peptide extract, as a potential intervention to counteract HFD-induced metabolic disturbances. Female ICR mice were divided into three groups: control diet, HFD, and HFD + PBPH, with PBPH (obtained by alcalase hydrolysis and ultrafiltration) administered daily for eight weeks. Researchers assessed adipokine levels, inflammatory cytokines, antioxidant enzymes, and apoptotic markers using qPCR, ELISA, histology, and immunohistochemistry. PBPH supplementation significantly improved metabolic parameters by lowering leptin, adipsin, resistin, IL-1β, TNF-α, and IL-6, while restoring antioxidant balance and reducing pro-apoptotic signals. Histological analyses confirmed preserved intestinal tissue and reduced inflammation. Overall, this study highlights PBPH's promising therapeutic role in addressing obesity-related metabolic dysfunctions through its multifaceted effects on inflammation, oxidative stress, and apoptosis. It underscores the potential of insect-derived peptides as sustainable, innovative dietary interventions for improving metabolic health.
