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

Invasive potentials of carcinomas greatly contribute to their metastasis, which is a major threat in most cancers. We have recently shown that Arf6 plays a pivotal role in breast cancer invasive activities and identified AMAP1 as an effector of GTP-Arf6 in invasion. Expression of AMAP1 correlates well with invasive phenotypes of primary tumors of the human breast. We also have shown that AMAP1 functions by forming a trimeric protein complex with cortactin and paxillin. In this complex, AMAP1 binds to the src homology 3 (SH3) domain of cortactin via its proline-rich peptide, SKKRPPPPPPGHKRT. SH3 domains are known to bind generally to the proline-rich ligands with a one-to-one stoichiometry. We found that AMAP1/cortactin binding is very atypical in its stoichiometry and interface structure, in which one AMAP1 proline-rich peptide binds to two cortactin SH3 domains simultaneously. We made a cell-permeable peptide derived from the AMAP1 peptide, and we show that this peptide specifically blocks AMAP1/cortactin binding, but not other canonical SH3/proline bindings, and effectively inhibits breast cancer invasion and metastasis. Moreover, this peptide was found to block invasion of other types of cancers, such as glioblastomas and lung carcinomas. We also found that a small-molecule compound, UCS15A, which was previously judged as a weak inhibitor against canonical SH3/proline bindings, effectively inhibits AMAP1/cortactin binding and breast cancer invasion and metastasis. Together with fine structural analysis, we propose that the AMAP1/cortactin complex, which is not detected in normal mammary epithelial cells, is an excellent drug target for cancer therapeutics.
