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

To explore mechanisms underlying the discrepancy in anti-tumor effects of metformin on pancreatic cancer cells PANC-1 under different glucose conditions. We cultured PANC-1 cells in 25 mM and 5 mM glucose media, then treated with or without metformin. It showed that metformin significantly inhibited proliferation and viability, induced apoptosis of PANC-1 cells, which was more pronounced in low-glucose than in high-glucose group. Metformin up-regulated the expression of miR-210-5p in low glucose, but not in high glucose. miR-210-5p mimic inhibited the viability of PANC-1 cells and further enhanced the inhibitory effect of metformin. miR-210-5p down-regulated the expression of PFKFB2, a predicted target gene of miR-210-5p, reduced the activity of PFK1 and LDH. Metformin significantly inhibited the expression of phosphorylation-PFKFB2(p-PFKFB2) in the low-glucose group and inhibited the LDH activity both in the low and high glucose groups, thus inhibiting anaerobic glycolysis and inducing energy stress. Cells in the high glucose group could make a compensatory adaptation to the energy stress induced by metformin through increasing glucose consumption. However, due to the limited glucose supply and high dependence on anaerobic glycolysis of cells in the low glucose group, they couldn't make effective adaptive compensation. Therefore, cells in the low-glucose group were more vulnerable to the toxicity of metformin. In conclusion, the enhanced inhibitory effect of metformin on PANC-1 cells cultured in low glucose may be due to the up-regulation of the expression of miR-210-5p, then inhibiting anaerobic glycolytic flux and inducing energy stress via repressing the expression of p-PFKFB2 and activity of LDH.
