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

Lysosomal-associated protein transmembrane 4 beta (LAPTM4B), a proto-oncogene, has been shown to be a positive modulator in cancer progression. However, the mechanism of LAPTM4B regulation is not fully elucidated. Aberrant microRNAs (miRNAs) can regulate gene expression by interfering with target transcripts and/or translation to exert tumor-suppressive or oncogenic effects in breast cancer. In the present study, miR-132-3p, which was predicted by relevant software, was confirmed to directly bind to the 3' untranslated region (3'UTR) of LAPTM4B and negatively regulate its expression in luciferase reporter and western blot assays. Subsequently, we validated that miR-132-3p was downregulated in breast cancer tissues. Receiver-operating characteristic curve analysis indicated that miR-132-3p had accurate diagnostic value, and a Kaplan-Meier and Cox regression model showed that miR-132-3p was a potential prognostic marker for recurrence, showing low levels in breast cancer patients. In addition, we showed that miR-132-3p was inversely correlated with LAPTM4B expression in the above samples. Functionally, miR-132-3p suppressed the migration and invasion of breast carcinoma cells through LAPTM4B by mediating epithelial-mesenchymal transition signals, and partially reversed the carcinogenic effects of LAPTM4B by inhibiting the PI3K-AKT-mTOR signaling pathway. Taken together, these findings provide the first comprehensive analysis of miR-132-3p as a direct LAPTM4B-targeted miRNA, and shed light on miR-132-3p/LAPTM4B as a significant functional axis involved in the oncogenesis and metastasis of breast cancer.
