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

Afatinib is the second generation of irreversible inhibitor of EGFR, HER2 and HER4, which has shown encouraging phase II and III clinical outcomes in the treatment of head and neck squamous cell carcinoma (HNSCC). However, the molecular mechanism of afatinib-induced apoptosis in HNSCC is poorly understood. In the present investigation, we discovered that down-regulation of MCL-1, an anti-apoptotic member of BCL-2 family, was responsible for afatinib-triggered apoptosis. And the inactivation of AKT-mTOR signaling caused by afatinib lead to translational inhibition of MCL-1 expression. As a crucial branch of ER stress, PERK-eIF2α-ATF4 axis was also stimulated in HNSCC cells after afatinib incubation. Silencing either eIF2α or ATF4 by siRNA transfection relieved afatinib-caused suppression of AKT-mTOR activity, attenuating MCL-1 down-regulation as well as subsequent apoptosis. Collectively, the results show that afatinib hampers AKT-mTOR activation by stimulating PERK-eIF2α-ATF4 signaling pathway, giving rise to MCL-1 down-regulation mediated apoptosis in HNSCC cells. Therefore, our findings reveal the elaborate molecular network of afatinib-induced apoptosis in HNSCC, which would provide substantial theoretical underpinnings for afatinib clinical application and highlight its promising prospect in HNSCC treatment.
