1 · What the graph read from it

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.

2 · The registry

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

We previously identified and characterized four galectin-1-like proteins in zebrafish, Drgal1-L1, Drgal1-L2, Drgal1-L3, and one splice variant of Drgal1-L2, of distinct ontogenic expression. Drgal1-L1 is maternal; Drgal1-L2 is zygotic and strongly expressed in the notochord, while Drgal1-L3 is both maternal and zygotic. Knockdown experiments in zebrafish embryos using a morpholino-modified antisense oligo targeted to the 5'-UTR sequence of Drgal1-L2 resulted in a phenotype with a bent tail and disorganized muscle fibers. This effect was dose-dependent as follows: 62-66% at 17 ng, 29-35% at 5.7 ng, 21-28% at 1.9 ng, and 14-17% at 0.6 ng. However, no (or a negligible number of) Drgal1-L1 knockdown embryos showed similar morphological defects, indicating that the observed effects are sequence-specific, and not due to the toxicity of the morpholino-modified oligos. Further, ectopic expression of native Drgal1-L2 specifically rescued the phenotype, as co-injection of the full-length sense Drgal1-L2 mRNA with Drgal1-L2-MO yielded 60-62% normal embryos. As the notochord serves as the primary source of signaling molecules required for proper patterning of adjacent tissues, such as neural tube, somites, and heart, these results suggest that galectins produced by the notochord play a key role in somitic cell differentiation and development.
