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

backgroundPolymerase θ (POLQ) is an error-prone translesion synthesis polymerase that participates in the repair of DNA double-strand breaks. Previous studies have reported that the level of POLQ expression is distinctly upregulated in colorectal cancer (CRC), but little attention has been given to its function and regulation of CRC progression. This study aimed to explore the specific function of POLQ in CRC.

methodsQuantitative real-time PCR and western blotting analysis were used to assess the transcription and translation levels of POLQ. Then, POLQ was stably silenced using small interfering RNA in SW480 and HCT116 cells. Afterwards, the function of POLQ in CRC cells was proven via Cell Counting Kit‑8, scratch wound healing, colony formation, and Boyden chamber assays. Furthermore, we investigated the effects of POLQ on the cell cycle signaling pathway that obtained from biological pathway enrichment analysis and further verified by activating the signaling pathway.

resultsThe results showed that POLQ was highly expressed in CRC tissues and cells and was associated with poor clinical outcomes of patients. Knockdown of POLQ significantly reduced the proliferation, migration and invasion of CRC cells. Additionally, POLQ knockdown markedly decreased the expression levels of MMP2 and MMP9, and blocked cell cycle progression by inhibiting the expression of G1/M and S/M phases proteins.

conclusionsPOLQ knockdown restrained the progression of CRC by blocking the cell cycle signaling pathway.
