Methyltransferase gene-mediated antiproliferative effect of 1,25(OH)2D3 on neuroblastoma cells.
Article in Revista da Associacao Medica Brasileira (1992), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objective1,25-Dihydroxyvitamin D3 is the body's active form of vitamin D and is also known as calcitriol. It has an effect on the body's immune system and is involved in the regulation of cell growth, differentiation, and apoptosis.
methodsThe effect of 1,25-Dihydroxyvitamin D3 on the viability of human neuroblastoma human neuroblastoma cell line cells was investigated by 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide assay, the effect on migration was investigated by wound healing assay, and methyltransferase genes (DNA methyltransferase 3 alpha and DNA methyltransferase 3 beta) and phosphatase and tensin homolog gene expression levels were investigated by real time polymerase chain reaction method.
resultsAs a result of the 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide assay, 1,25-Dihydroxyvitamin D3 IC50:265.6 nM was found. It was observed that 100 and 265.6 nM applied to human neuroblastoma cell line cells had an antiproliferative effect. In addition, DNA methyltransferase 3 alpha and DNA methyltransferase 3 beta genes, which are effective as methyltransferases, caused a change in expression levels (p<0.05), while phosphatase and tensin homolog expression levels did not change (p>0.05).
conclusion1,25-Dihydroxyvitamin D3 showed antiproliferative, antimigratory activity on neuroblastoma human neuroblastoma cell line cells and decreased the expression levels of genes involved in methylation, which may be evidence of its anticancer effect.
