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

introductionCD146 is highly expressed in various malignant tumors and contributes to their malignancy phenotype, which involves metastatic and tumorigenic activity. However, studies on the expression and function of CD146 in brain tumors are limited.

methodsWe over-expressed or knocked-down CD146 in both conventionally cultured glioma cells and tumor spheres (TS). The distribution of glioma cells and their stem cells in different cell cycle phases was analyzed by flow cytometry using the stem cell marker CD133 and the glial precursor marker A2B5. CD146 expression was immunohistochemically examined in glioma tissues.

resultsThe majority of glioma stem cells (GSCs) expressing CD133 were also CD146-positive. CD146 knockdown in GSCs significantly compromised cell growth. Cell cycle analysis revealed that most of the CD146 and CD133 double-positive cells were in the G2/M phase. Ectopic expression of CD146 in parental glioma cells resulted in cell cycle arrest of most differentiated cells in G0/G1 phase. In contrast, ectopic expression of CD146 in GSCs resulted in an increase in the number of CD133-positive cells in the G2/M phase. Furthermore, CD146 knockdown reduced the number of CD133-positive cells in the G2/M phase, which was consistent with effects of cell growth inhibition. Immunohistochemical analysis revealed that CD146 expression was significantly upregulated in World Health Organization (WHO) Grade III and IV glioma and positively correlated with CD133 expression.

conclusionsCD146 is mainly expressed in dividing GSCs and may be a potential target for eradicating glioma stem cells.
