Identification and Biological Characterization of a Novel NRF2 Activator Molecule Released From the Membranes of Heat-Treated Bifidobacterium breve NCC 2950.
Article in Molecular nutrition & food research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Postbiotics are defined as a "preparation of inanimate microorganisms and/or their components that confers a health benefit on the host". They represent an attractive alternative to probiotics as they could be used in a broader range of applications, where probiotic stability is limiting. To date knowledge on the mechanism of action of inanimate microorganisms is relatively scarce. In this study, we investigated the impact of heat treatment on NRF2 activation by several candidate probiotic strains from the Nestlé Culture Collection (NCC), including species encompassed in the Bifidobacterium genus and the Lactobacillaceae family. We identified an NRF2-activating bioactive molecule, 4-oxo-2-pentenoic acid (OPA), specifically released during heat treatment of Bifidobacterium breve NCC 2950. We explored cellular pathways that can be modulated by OPA, such as antiinflammatory signals and organismal defense against oxidative stress in zebrafish in vivo. We identified a new B. breve NCC 2950-derived postbiotic that, based on the mode of action, may have important applications for nutritional strategies to benefit human health.
