Plasma exosomal miR-122 regulates the efficacy of metformin
Article in Heliyon, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
Metformin is a drug that has been applied in clinical use for many years for the treatment of type 2 diabetes mellitus (T2DM). It achieves its function through multiple targets and modulation of multiple signaling pathways. To date, the mechanism of the action of metformin is still not fully understood. Along with glycemic control, metformin has shown good inhibitory effects on the development of many tumors. Here, we elucidated that plasma exosomal microRNA-122-5p (miR-122) is closely related to the mechanism of metformin. MiR-122 regulates glycogen-glucose metabolism in hepatocytes or hepatocellular carcinoma cells (HCC) by inhibiting the phosphorylation of AMPK. Since miR-122 and metformin regulate glucose metabolism homeostasis through similar mechanisms, miR-122 can antagonize the effects of metformin. MiR-122 expression increases the sensitivity of hepatocytes or HCC to metformin. Conversely, decreased expression of miR-122 results in hepatocyte insensitivity to metformin. Therefore, significantly elevated levels of miR-122 in plasma exosomes of hepatocellular carcinoma patients could enhance their sensitivity to metformin. The results of the present study revealed a key regulatory role of plasma exosomal miR-122 on the molecular mechanism of metformin. The regulation of key molecules of related signaling pathways by miR-122 may lead to similar glycemic lowering and tumor suppression therapeutic effects as metformin. This provides new ideas for the development of new therapeutic strategies for hepatocellular carcinoma based on the mechanism of miR-122 and metformin.
