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

Species from lower invertebrates to a spectrum of mammals show antiaging health benefits of phytochemical(s). Here, we explored the pro-longevity effects of a natural triterpenoid, ursolic acid (3β-hydroxy-urs-12-en-28-oic acid; UA) in Caenorhabditis elegans with maximal life span being evident at 25 µM UA. Similar to eat-2 mutants, UA uptake by worm results in reduced fat storage and attenuation of reactive oxygen species (ROS), independent of superoxide dismutase(s) activation. The genetic requirements for UA-mediated longevity are quite similar to dietary restriction (DR) achieved through SKN-1/NRF-2 exhibiting upregulation of downstream target genes gcs-1 and daf-9. Longevity mechanism was independent of PHA-4/FOXA and attributed to partial dependence on sir-2.1. Altogether, our study suggests differential use of UA-elicited signaling cascades in nutrient sensing for longevity. Both the redox state and the proteostasis of an organism play critical role in aging and disease resistance. Interestingly, we observed a reduction of toxic protein aggregation in transgenic polyglutamine (polyQ) C. elegans model and UA-mediated JNK-1 (c-Jun-NH2-terminal kinase) activation in wild-type animals. Thus, our study demonstrates a small extent of prevention against proteotoxic stress by UA coupled with positive aspects of DR-mediated longevity.
