Cathepsin-B dependent autophagy ameliorates steatoheaptitis in chronic exercise rats.
Article in Histology and histopathology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
purposeThis study aimed to investigate the role of cathepsin B dependent autophagy induced by chronic aerobic exercise on a high-fat diet (HFD)-induced nonalcoholic steatohepatitis (NASH) in rats.
methodsHealthy female (Sprague-Dawley) SD rats (8-10 weeks old; 180g-200g; n=6 per group) were divided into: (1) control group; (2) HFD group; (3) Exercise group; (4) HFD + exercise group. Rats were fed with a normal chow or an HFD for 12 weeks. Rats with exercise ran on a rotarod for 30 min per day from weeks 9-12.
resultsExercise training significantly (1) upregulated the levels of autophagy markers Beclin1, ATG5 and LC3II partly through inhibiting the p-AKT/mTOR pathway; (2) ameliorated HFD-mediated accumulation of fat mass by upregulating β-oxidation regulator PPAR-α and downregulating fatty acid synthesis marker SREBP-1c via lipophagy; (3) diminished the HFD-induced hepatic pro-inflammatory mediators TNF-α and IL-1β via NF-κB inactivation; (4) decreased the NASH-induced hepatic apoptotic marker caspase-3 activation caused by the upstream oxidative stress and by cytochrome P450 2E1 (CYP2E1); (5) mitigated the HFD-mediated lysosomal membrane permeabilisation and cathepsin B release partly via the reduction of reactive oxygen species (ROS).
conclusionsChronic aerobic exercise reduces oxidative stress/ROS and ROS may cause lysosomal membrane destabilisation and disrupts the autophagic process. The beneficial effect of chronic exercise may further inhibit the process of lysosome membrane permeabilisation and facilitate lysosome fusion with autophagosomes to trigger autophagy. This process may possibly contribute to the inhibition of cathepsin B released into cytosol which further reduces inflammation and mitochondrial-dependent apoptosis.
