Selection of reference genes and proteins for expression studies in pediatric gliomas.
Article in Discover oncology, 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
A critical aspect of gene and protein expression analysis is the selection of stable reference genes and proteins. These references are essential for normalizing data and enabling accurate comparisons between samples. In today’s context, molecular typing is essential to enhance diagnostic precision and inform therapeutic decisions, further emphasizing the need for reliable reference molecules. In this study, we analyzed the expression levels of six reference gene candidates and seven proteins in pediatric glioma samples. Gliomas are the most common solid tumors found in the central nervous system of children and are typically classified into low-grade gliomas, optic pathway gliomas, and high-grade gliomas. We evaluated the expression levels of the six target genes using RefFinder web-based software. Our findings indicate that YWHAZ and GAPDH are the most reliable pairs of reference genes, while β-Actin and 14-3-3ζ serve as the most dependable reference proteins. Interestingly, the expression of putative housekeeping proteins in low-grade gliomas closely resembles that in high-grade gliomas but differs from the expression observed in optic pathway gliomas. Furthermore, we found no correlation between RNA amounts and protein levels, suggesting variations in how protein expression is regulated. Overall, the results show that the expression of reference genes in pediatric gliomas differs from what has been reported for adult gliomas. This research provides valuable insights into the molecular characteristics of pediatric gliomas and may have important implications for diagnosis and treatment.
