ARL13B-Cerulean rescues Arl13b-null mouse from embryonic lethality and reveals a role for ARL13B in spermatogenesis.
Article in Journal of cell science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
ARL13B is a regulatory GTPase enriched in cilia, making it a popular marker for this organelle. Arl13bhnn/hnn mice lack ARL13B expression, die during mid-gestation, and exhibit defects in ciliogenesis. The R26Arl13b-Fucci2aR biosensor mouse line directs the expression of fluorescently tagged full-length Arl13b cDNA upon Cre recombination. To determine whether constitutive, ubiquitous expression of Cerulean-tagged ARL13B (ARL13B-Cerulean) can replace endogenous gene expression, we generated Arl13bhnn/hnn animals expressing ARL13B-Cerulean. We show that Arl13bhnn/hnn;Arl13b-Cerulean mice survive to adulthood with no obvious physical or behavioral defects, indicating that the fluorescently tagged protein can functionally replace the endogenous protein during development. However, we observed that rescued males failed to sire offspring, revealing a role for ARL13B in spermatogenesis. This work shows that the R26Arl13b-Fucci2aR mouse contains an inducible allele of Arl13b capable of functioning in most tissues and biological processes.
