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

N6‑methyladenosine (m6A) RNA modification maintained by N6‑methyltransferases and demethylases is involved in multiple biological functions. Methyltransferase like 3 (METTL3) is a major N6‑methyltransferase. However, the role of METTL3 and its installed m6A modification in colorectal tumorigenesis remains to be fully elucidated. METTL3 is highly expressed as indicated in colorectal cancer samples in the TCGA and Oncomine databases, implying its potential role in colon tumorigenesis. SW480 cell line with stable METTL3 knockout (METTL3‑KO) was generated using CRISPR/Cas9 and were confirmed by the loss of METTL3 expression and suppression of m6A modification. The proliferation of METTL3‑KO cells was significantly inhibited compared with that of control cells. METTL3‑KO decreased the decay rate of suppressor of cytokine signaling 2 (SOCS2) RNA, resulting in elevated SOCS2 protein expression. m6A‑RNA immunoprecipitation‑qPCR (MeRIP‑qPCR) revealed that SOCS2 mRNA was targeted by METTL3 for m6A modification. Similar to METTL3‑KO SW480 cells, SW480 cells treated with 3‑deazaadenosine, an RNA methylation inhibitor, exhibited elevated SOCS2 protein expression. Increased levels of SOCS2 in METTL3‑KO SW480 cells were associated with decreased expression of leucine‑rich repeat‑containing G protein‑coupled receptor 5 (LGR5), contributing to the inhibition of cell proliferation. The underlying associations among METTL3, SOCS2, and LGR5 were further confirmed in SW480 cells transfected with si‑METTL3 and in tumor samples from patients with colorectal cancer. Taken together, our data demonstrate that an increased level of METTL3 may maintain the tumorigenicity of colon cancer cells by suppressing SOCS2.
