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

Peptidylarginine deiminase type 4 (PADI4) post-translationally converts peptidylarginine to citrulline, appearing to be overexpressed in numerous carcinomas. The current study aimed to investigate the expression of PADI4 in gastric cancer tissues and its effect on the biological activities of SGC-7901 and AGS tumor cell lines. The expression of PADI4 was determined in gastric cancer and normal gastric mucosa tissues using western blot analysis and reverse transcription-quantitative polymerase chain reaction. Gastric cancer cell lines were divided into the following groups: Mock group (subjected to transfection reagent); negative group [subjected to small interfering RNA (siRNA) transfection]; PADI4 siRNA group (subjected to PADI4 siRNA transfection); 5-fluorouracil (5-Fu) group (subjected to 5-Fu); and 5-Fu + siRNA transfection group (subjected to 5-Fu and PADI4 siRNA transfection). The effects of silencing PADI4 with the above measures on the proliferation and invasion of SGC-7901 and AGS cells were determined by MTT and Transwell chamber assays. In addition, propidium iodide staining was performed to detect the effects of PADI4 on the cell cycle. A significant increase in the expression of PADI4 mRNA in gastric cancer tissue compared with normal mucosa tissue was identified (P<0.05). The proliferation and invasion of SGC-7901 and AGS cells were significantly decreased in the PADI4 siRNA group. Furthermore, flow cytometry DNA analysis revealed that silencing PADI4 resulted in significant S phase arrest and marked decrease of cells in the G2/M phase. PADI4 siRNA coupled with 5-Fu significantly enhanced its inhibitory effect on the proliferation of gastric cancer cells. In conclusion, PADI4 demonstrated high expression in gastric cancer and served an important role in the biological activities of gastric cancer cells involving cell proliferation, invasion and cell cycle. As a result, PADI4 may be a valid cancer susceptibility gene and potential target for cancer therapy.
