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

Glioblastoma is the most common and aggressive primary brain tumor in adults, with a poor prognosis because of its resistance to radiotherapy and chemotherapy. Merlin/NF2 (moesin-ezrin-radixin-like protein/neurofibromatosis type 2) is a tumor suppressor found to be mutated in most nervous system tumors; however, it is not mutated in glioblastomas. Merlin associates with several transmembrane receptors and intracellular proteins serving as an anchoring molecule. Additionally, it acts as a key component of cell motility. By selecting sub-populations of U251 glioblastoma cells, we observed that high expression of phosphorylated Merlin at serine 518 (S518-Merlin), NOTCH1 and epidermal growth factor receptor (EGFR) correlated with increased cell proliferation and tumorigenesis. These cells were defective in cell-contact inhibition with changes in Merlin phosphorylation directly affecting NOTCH1 and EGFR expression, as well as downstream targets HES1 (hairy and enhancer of split-1) and CCND1 (cyclin D1). Of note, we identified a function for S518-Merlin, which is distinct from what has been reported when the expression of Merlin is diminished in relation to EGFR and NOTCH1 expression, providing first-time evidence that demonstrates that the phosphorylation of S518-Merlin in glioblastoma promotes oncogenic properties that are not only the result of inactivation of the tumor suppressor role of Merlin but also an independent process implicating a Merlin-driven regulation of NOTCH1 and EGFR.
