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

Previous studies have demonstrated that AMP-activated protein kinase (AMPK) controls autophagy through the mammalian target of rapamycin (mTOR) and Unc-51 like kinase 1 (ULK1/Atg1) signaling, which augments the quality of cellular housekeeping, and that β-guanidinopropionic acid (β-GPA), a creatine analog, leads to a chronic activation of AMPK. However, the relationship between β-GPA and aging remains elusive. In this study, we hypothesized that feeding β-GPA to adult Drosophila produces the lifespan extension via activation of AMPK-dependent autophagy. It was found that dietary administration of β-GPA at a concentration higher than 900 mm induced a significant extension of the lifespan of Drosophila melanogaster in repeated experiments. Furthermore, we found that Atg8 protein, the homolog of microtubule-associated protein 1A/1B-light chain 3 (LC3) and a biomarker of autophagy in Drosophila, was significantly upregulated by β-GPA treatment, indicating that autophagic activity plays a role in the effect of β-GPA. On the other hand, when the expression of Atg5 protein, an essential protein for autophagy, was reduced by RNA interference (RNAi), the effect of β-GPA on lifespan extension was abolished. Moreover, we found that AMPK was also involved in this process. β-GPA treatment significantly elevated the expression of phospho-T172-AMPK levels, while inhibition of AMPK by either AMPK-RNAi or compound C significantly attenuated the expression of autophagy-related proteins and lifespan extension in Drosophila. Taken together, our results suggest that β-GPA can induce an extension of the lifespan of Drosophila via AMPK-Atg1-autophagy signaling pathway.
