Investigating the role of dachshund b in the development of the pancreatic islet in zebrafish.

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
AIMS/
introductionβ-Cell dysfunction is a hallmark of type 2 diabetes. In a previous pilot study, we identified an association between genetic variants within the human DACH1 gene and young-onset type 2 diabetes. Here, we characterized the function of dachb, the only dach homologue to be expressed in the pancreas, in developing zebrafish embryos. MATERIALS AND
methodsWe injected one-cell stage embryos with a dachb-morpholino (MO) or with the dachb-MO and dachb messenger ribonucleic acid, and determined the effect on the development of the pancreatic islet. We also carried out quantitative polymerase chain reaction and ribonucleic acid sequencing on the dachb-MO group to determine the effect of dachb knockdown on gene expression.
resultsMO-mediated dachb knockdown resulted in impaired islet cell development, with a significant decrease in both the β-cell and islet cell numbers. This islet developmental defect was rescued when embryos were co-injected with dachb-MO and dachb messenger ribonucleic acid. Knockdown of dachb was associated with a significant downregulation of the β-cell specific marker gene, insa, and the somatostatin cell marker, sst2, as well as regulators of pancreas development, ptf1a, neuroD, pax6a and nkx6.1, and the cell cycle gene, insm1a. Furthermore, ribonucleic sequencing analysis showed an upregulation of genes enriched in the forkhead box O and mitogen-activated protein kinase signaling pathways in the dachb-MO group, when compared with the control groups.
conclusionsTogether, our results suggest the possible role of dachb in islet development in zebrafish.
