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

Disseminated forms of neuroblastoma (NB), a tumor derived from neuroectodermal tissue, pose a major therapeutic challenge for pediatric oncology. By performing a comparative cDNA array analysis of metastatic neuroblasts versus primary xenograft from the human IGR-N-91 NB model, we were able to identify a set of downregulated developmental genes in metastatic neuroblasts. One of these genes was Wnt-5a, a member of the Wnt signaling pathway, known to be involved in the development of neural crest cells. Since we also found a significant decrease in Wnt-5a mRNA in unfavorable versus favorable categories in 37 primary NB tumors (P<0.007), we wondered whether retinoic acid (RA), which has a role in neural crest induction and differentiation, might reverse the aberrant negative regulation of Wnt-5a in metastatic malignant neuroblasts. Following treatment with 10 muM RA for 6 days, the MYCN-amplified IGR-N-91 cell lines underwent neuronal differentiation as assessed by reduced MYCN gene expression and neuritic extension. In these conditions, data showed an upregulation of Wnt-5a and PKC-theta; isoform expressions. Our study highlights, for the first time, the involvement of Wnt-5a, which has a role in embryonic and morphogenetic processes, in the response of malignant neuroblasts to RA. In conclusion, we demonstrated that RA, which is used in the treatment of high-risk NB patients with recurrent/residual disease in the bone marrow, is able to upregulate Wnt-5a gene expression.
