EFEMP1 binds to STEAP1 to promote osteosarcoma proliferation and invasion via the Wnt/β-catenin and TGF-β/Smad2/3 signal pathways.

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
Purpose: To investigate the prognostic value and function of six-transmembrane epithelial antigen of prostate 1 (STEAP1) in osteosarcoma and determine whether EFEMP1 mediates its effects. Methods: IHC (immunohistochemistry)/ICC (immunocytochemistry) in conjunction with RT-qPCR (quantitative real-time polymerase chain reaction) were employed to assess the expression of STEAP1 in paratumoral tissues, osteosarcoma, benign fibrous dysplasia, osteosarcoma cells, normal osteoblastic hFOB cells, as well as various invasive subclones. The association of STEAP1 with outcome was examined with Kaplan-Meier graph among the osteosarcoma population. The effects of the down-regulation and up-regulation of STEAP1 on the biological behavior of osteosarcoma cells were studied through Results: Up-regulation of STEAP1 in the osteosarcoma tissues, whose correlations with the malignant osteosarcoma phenotype and the poor patient outcome were positive. In addition, STEAP1 induced the epithelial-mesenchymal transition (EMT) via the Wnt/β-catenin and TGF-β/Smad2/3 pathways and facilitated the osteosarcoma cell infiltration and migration. An increase or decrease in EFEMP1 expression directly promoted or inhibited the expression of STEAP1. In osteosarcoma cells overexpressing EFEMP1, STEAP1 knockdown significantly inhibited cell invasion, EMT process, and increased activity of Wnt/β-catenin and TGF-β/Smad2/3 signaling pathways. Although exogenous EFEMP1 could stimulate the Wnt/β-catenin and TGF-β/Smad2/3 pathways to promote the EMT, it had not effect on osteosarcoma cells with STEAP1 knockdown. Collectively, similar to Conclusion: EFEMP1 enabled the Wnt/β-catenin and TGF-β/Smad2/3 axises initiation and EMT elicitation by targeting STEAP1, thereby facilitating the osteosarcoma cell infiltration and migration. These results are expected to contribute to the search for new targeted drugs able to effectively inhibit invasion and metastasis and improve prognosis in osteosarcoma.
