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

Period2 (Per2) is a key mammalian circadian clock protein, and additionally has a tumor suppressive function. The present study aimed to investigate its role in drug resistance in A549/cisplatin (DDP) lung adenocarcinoma cells. Per2 knockdown and overexpression in A549/DDP cells were used to compare cell proliferation (by MTT assay), apoptosis (active-caspase 3 western blot) and clone forming assay. The activation of AKT/mechanistic target of rapamycin (mTOR) was investigated by a western blot assay. The Per2 expression level was decreased in A549/DDP cells compared with A549 cells. Per2 knockdown by short hairpin RNA protects A549/DDP cells from apoptosis, and promotes proliferation and migration. Per2 knockdown results in increased activation of the phosphoinositide 3-kinase (PI3K)/AKT/mTOR signaling pathway. Overexpression of Per2 in A549/DDP cells may reduce the activity of the PI3K/AKT/mTOR signaling pathway, and promote apoptosis of A549 cells. The results of the present study suggest that Per2 participates in AKT-mediated drug resistance in A549/DDP lung adenocarcinoma cells.
