Expression of Human Uncoupling Protein-1 in Escherichia coli Decreases its Survival Under Extremely Acidic Conditions.
Article in Current microbiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Uncoupling protein-1 (UCP1), located at the inner membrane of mitochondria, is expressed primarily in brown adipose tissue and mediates the permeability of protons through the inner mitochondrial membrane. This research examines whether human UCP1 can uncouple oxidative phosphorylation in E. coli. Recombinant human UCP1 that includes an N terminus signal peptide for the bacterial inner membrane was expressed in E. coli. Our testing showed that UCP1 functions as a proton transporter in the bacterial membrane, increasing its permeability, decrease ATP synthesis at neutral pH and reducing the viability of E. coli in markedly acidic environments. These results suggest that UCP1 can uncouple oxidative phosphorylation in E. coli. The decreased acid resistance (AR) of E. coli with UCP1 expressed in the membranes confirmed that oxidative phosphorylation plays a role in AR through the pumping of protons to regulate the intracellular pH, and demonstrate that UCP1 can be used as an uncoupler protein for bacterial metabolic research.
