On-demand delivery of fibulin-1 protects the basement membrane during cyclic stretching in C. elegans.
Article in Developmental cell, 2025. 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
Basement membrane (BM) extracellular matrices enwrap and structurally support tissues. Whether BMs are uniquely constructed for tissues to undergo repetitive stretching and recoil events is unknown. During C. elegans ovulation, the spermathecal BM stretches ∼1.7-fold and then recoils to its original shape every 20 min to passage hundreds of oocytes. Fluorescence microscopy demonstrated that ovulating oocytes deliver the extracellular matrix protein fibulin-1 (FBL-1) through the spermathecal cell junctions to the BM during stretching, where it forms a dynamic overlapping network with type IV collagen. FBL-1 depletion led to a breakdown in type IV collagen and BM organization, resulting in a more deformable BM and extended spermatheca. Moreover, perturbation to FBL-1 network formation via mutagenesis was sufficient to disrupt tissue recoil and shape. Together, our study identifies an on-demand FBL-1 delivery system that protects the BM network when it is stretched, thereby allowing repeated rounds of tissue expansion and recovery.
