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

Osteosarcoma (OS) is one of the most common types of primary sarcoma of bone in children and young adults, and the long-term prognosis for OS patients still remains dismal due to the lack of effective early diagnostic biomarkers. Identifying sensitive and specific biomarkers in carcinogenesis may improve diagnostic and therapeutic strategies for this malignancy. The expression of miR-664 in osteosarcoma cell lines and osteosarcoma tissues was examined using real-time PCR. The effects of miR-664 on osteosarcoma cell migration and invasion were evaluated by cell invasion assays, migration assays, and three-dimension spheroid invasion assay. The effect of miR-664 on SOX7 was determined by luciferase assays and Western blot assay. The clinical association between miR-664 and SOX7 was analyzed by real-time PCR and Western blot assay. Expression of miR-664 was found to be upregulated in OS cell lines and tissues. Overexpression of miR-664 was associated with increased migration and invasive abilities of OS cells in vitro, whereas downregulation of miR-664 appeared to inhibit their migration and invasive potential. Furthermore, using biological approaches, we showed that miR-664 directly targeted and suppressed expression of the tumor suppressor SOX7. Additionally, the expression of miR-664 was negatively correlated with SOX7 expression in OS clinical tissues. Our findings suggest that miR-664 functions as an oncogene miRNA and has an important role in promoting human OS cell invasion and migration by suppressing SOX7 expression. Consequently, miR-664 may have potential as a novel diagnostic and therapeutic target of osteosarcoma.
