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

backgroundHuman basal-like breast cancer (BLBC) has a poor prognosis and is often identified by expression of the epidermal growth factor receptor (EGFR). BLBC remains a major clinical challenge because its pathogenesis is not well understood, thus hindering efforts to develop targeted therapies. Recent data implicate the forkhead box C1 (FOXC1) transcription factor as an important prognostic biomarker and functional regulator of BLBC, but its regulatory mechanism and impact on BLBC tumorigenesis remain unclear.

methodsThe association between FOXC1 and EGFR expression in human breast cancer was examined by immunohistochemistry in formalin-fixed tissues and analysis of the TCGA database. The regulation of FOXC1 by EGFR activation was investigated in MDA-MB-468 cells using immunoblotting, qRT-PCR, and luciferase activity assays. This EGFR effect on FOXC1 expression was confirmed using the MDA-MB-468 xenograft model.

resultsBoth FOXC1 mRNA and protein levels significantly correlated with EGFR expression in human breast tumors. EGFR activation induced FOXC1 transcription through the ERK and Akt pathways in BLBC. EGFR inhibition in vivo reduced FOXC1 expression in xenograft tumors. We also found that FOXC1 knockdown impaired the effects of EGF on BLBC cell proliferation, migration, and invasion.

conclusionsOur findings uncover a novel EGFR-FOXC1 signaling axis critical for BLBC cell functions, supporting the notion that intervention in the FOXC1 pathway may provide potential modalities for BLBC treatment.
