Fibronectin and Hand2 influence tubulogenesis during pronephros development and mesonephros regeneration in zebrafish (Danio rerio).
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
Worldwide incidence of kidney diseases has been rising. Thus, recent research has focused on zebrafish, whose fast development and innate regeneration capacity allow identifying factors influencing renal processes. Among these poorly studied factors are extracellular matrix (ECM) proteins like Fibronectin (Fn) essential in various tissues but not yet evaluated in a renal context. We utilized early nat and han zebrafish mutant embryos and carrier adults to investigate Fn's role during kidney development and regeneration. The locus natter (nat) encodes Fn and the locus han encodes Hand2, which results in increased Fn deposition. Our results show that Fn impacts identity maintenance and morphogenesis during development and influences conditions for neonephrogenic cluster formation during regeneration. Histological analysis revealed disrupted pronephric structures and increased blood cell accumulation in Fn mutants. Despite normal expression of specification markers (pax2, ATPα1a.1), structural abnormalities were evident. Differences between wild-type and mutation-carriers suggest a haploinsufficiency scenario. These findings reveal a novel function for ECM in renal development and regeneration, with potential implications for understanding and treating kidney diseases.
