Go Fish! Hepatic Uptake of Clinical Hepatospecific Gadolinium-Based MRI Contrast Agents in Zebrafish is Similar to Humans.

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
purposeZebrafish are a useful organism for investigating liver disease due to their genetic similarities with humans, particularly in genes associated with liver function. It has been posited that liver function can be assessed non-invasively by MRI, measuring the hepatic accumulation of gadolinium-based contrast agents (GBCAs). We characterized the hepatic uptake of various hepatospecific and non-hepatospecific clinical GBCAs in zebrafish. PROCEDURES: To introduce GBCAs systemically, zebrafish swam for 30 min in water containing 5 mM of various clinical hepatospecific or non-hepatospecific GBCAs. Fish were then sacrificed and underwent 3D, T1-weighted, high-resolution MRI at 9.4 T. In vitro MRI and transport studies of the same GBCAs were conducted in HEK293T cells transiently expressing OATP1D1, OATP1B2 and OATP1B3.
resultsT1-weighted ex-vivo MRI of zebrafish showed hyperintensity in the liver, gall bladder, bile ducts, and intestine for fish swimming in gadoxetate, but not for in gadobenate nor gadoterate. In vitro cell experiments confirm that gadoxetate but not gadobenate is efficiently transported by OATP1D1.
conclusionZebrafish liver accumulates gadoxetate but not gadobenate via OATP1D1 transport, among the two clinical hepatospecific MRI GBCAs, and also does not accumulate gadoterate, a non-hepatospecific GBCA. This pattern of GBCA hepatic uptake is similar to humans but differs from all other non-primates reported, which exhibit high hepatic uptake of both gadoxetate and gadobenate.
