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

backgroundThe study aims to evaluate the expression and activity of glycogen synthase kinase 3 isoforms α/β (GSK3α/β) and to assess their oncogenic potential through a correlation with the expression of cyclin D1 and p53 in oral cancer.

methodsThe expression of total and phosphorylated GSK3α/β as well as cyclin D1 and p53 together with their interaction were assessed in human oral cancer tissue samples, apparently normal adjacent tissues, benign tumor samples, premalignant lesions and healthy normal tissues (total 179) using various methods, such as immunohistochemistry, Western blot assays, immunoprecipitation and RT-PCR analysis.

resultsThe expression of GSK3β was significantly higher relative to GSK3α indicating the greater role of the β isoform in oral cancer. Among various types of oral cancers, OSCC (of the lip and tongue) showed elevated expression of GSK3α/β, and the expression was correlated with disease progression. The increased expression of pS(21)GSK3α and pS(9)GSK3β not only correlated positively with cyclin D1 and p53 expression in tongue cancer progression but a gradual shift of their expression from the cytoplasmic to the nuclear compartment and overall disease severity was also observed. The interaction of GSK3β-cyclin D1 and the positive correlation of pS(9)GSK3β and the transcription of cyclin D1 were observed.

conclusionsThese results demonstrate that the inactivation of GSK3β is an important event in OSCC and can be used as a marker for assessing disease severity and may be exploited for therapeutic intervention.
