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

The proliferation and apoptosis of tumor cells are regulated by a variety of microRNAs (miRs). miR‑21 can inhibit the apoptosis of cancer cells in vitro. Tumor necrosis factor α (TNF‑α) serves an important role in the induction of proliferation of cervical cancer cells. Previous studies have demonstrated that the expression level of miR‑21 is associated with TNF‑α expression in alveolar macrophages. However, to the best of our knowledge, whether miR‑21 regulates TNF‑α in cervical cells has not been reported. The present study was designed to investigate whether miR‑21 regulates TNF‑α expression, proliferation and apoptosis of cervical cancer cells. miR‑21, miR‑21 inhibitor and control miRNA were synthesized and transfected into HeLa cervical cancer cells. Reverse transcription‑quantitative polymerase chain reaction was used to measure the expression levels of miR‑21 and TNF‑α at the mRNA level. Western blotting was used to measure the expression levels of TNF‑α at the protein level. MTT assay and Hoechest‑33342 staining were used to measure the proliferation and apoptosis of HeLa cells. miR‑21 was identified to upregulate the mRNA and protein expression levels of TNF‑α. Furthermore, upregulation of TNF‑α enhanced the proliferation capability of HeLa cells. Changes in the expression levels of miR‑21 and TNF‑α did not significantly affect the apoptosis of Hela cells. In conclusion, the present study demonstrated that miR‑21 regulates the expression of TNF‑α in HeLa cells. Additionally, the expression level of TNF‑α was positively associated with the proliferation capability of Hela cells, but not apoptosis. Therefore, miR‑21 regulates the proliferation of HeLa cells through regulation of TNF‑α. These results provide novel potential therapeutic targets for the treatment of cervical cancer.
