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

The HCLS1-Binding Protein 3 (HS1BP3) interacts with the SH3 domain of cortactin (CTTN), a protein that contributes to a malignant phenotype in cancers. Here, we demonstrate that high expression of HS1BP3 is associated with reduced survival for gastric adenocarcinoma and triple negative breast carcinoma patients and that HS1BP3 is specifically upregulated in these cancers. We mapped the HS1BP3-cortactin interaction site to the third proline-rich region (PRR3.1) of HS1BP3 and show that this interaction is important for cancer cell proliferation, extracellular matrix degradation and secretion. HS1BP3 expression was found to correlate with expression of the invadopodia scaffold protein TKS5 and we show that the localisation of TKS5 inside multivesicular endosomes is increased in cells expressing an HS1BP3 PRR3.1 mutant. Overall, our results highlight the importance of the direct interaction between HS1BP3 and cortactin in cancer development by regulating cell proliferation, secretion and invasion, which may provide an explanation for the negative correlation between HS1BP3 levels and the survival of gastric adenocarcinoma and triple negative breast cancer patients.
