Circ_103128 is associated with the tumorigenesis of medulloblastoma.
Article in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
BACKGROUND &
aimsMedulloblastoma (MB) is a primary malignant tumor of the brain. They are categorized as WHO grade IV neoplasms, and mostly occur in children. The traditional therapy for MB is surgery, followed by radiation and chemotherapy, but the clinical outcome is still poor and has a high possibility of recurrence. The mechanism underlying the development of MB should be further investigated to develop novel therapeutic strategies.
methodsResearch has demonstrated that circRNAs contribute to tumorigenesis, but the functional mechanism of circRNAs in MB has not been fully explored and remains vague. The differentially expressed circRNAs between MB and normal cerebellar tissues were analyzed based on the microarray expression profiles to characterize the potential mechanism of circRNAs in MB.
resultsThe results revealed that circRNA_103128 was highly expressed in MB, and cellular and animal experiments were performed to verify its tumorigenic effect in MB. Furthermore, a bioinformatics analysis and literature review previous literature were performed, confirming miR-129-5p as a target gene downstream of circRNA_103128. In addition, SOX4 was predicted to be a downstream target protein of miR-129-5p. Subsequently, miR-129-5p expression was inhibited, which revealed the regulatory mechanism of circRNA_103128. The latter promotes MB cell growth, migration, and invasion by the sponge effect of miR-129-5p, thereby affecting the expression of SOX4.
conclusionsThis study is the first to systematically demonstrate that circRNA_103128 may play an important regulatory role in MB through a sponge effect with miR-129 -5p, which affects SOX4 expression and regulates tumorigenesis and tumor cell development in MB.
