Cudrania tricuspidata water extract improved obesity-induced hepatic insulin resistance in db/db mice by suppressing ER stress and inflammation.
Article in Food & nutrition research, 2015. 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
backgroundObesity can play a role in the development of hepatic insulin resistance. Although the molecular mechanism of the association between obesity and hepatic insulin resistance is unclear, it has been reported that obesity leads to hepatic endoplasmic reticulum (ER) stress and inflammation, which can induce the development of insulin resistance in several tissues.
objectiveIn this study, we investigated the associations between hepatic insulin resistance, ER, and inflammation in obesity and the effect of water extract from Cudrania tricuspidata leaves (CTL) on hepatic insulin resistance induced by ER stress and inflammation in db/db mice.
designThe mice were randomly divided into four groups: a normal control group (C57BL/6J), a control group (C57BL/6J-db/db), a CTL 100 group (C57BL/6J-db/db mice fed a dietary supplement of 100 mg/kg of CTL), and a CTL 300 group (C57BL/6J-db/db mice fed a dietary supplement of 300 mg/kg of CTL). After 8 weeks, we performed an oral glucose tolerance test and the mice were sacrificed.
resultsThe C57BL/6J-db/db mice developed obesity and hyperglycemia, and the ER stress response and inflammation were activated in their livers. Interestingly, there was a marked decrease in the activation of the ER stress response and insulin resistance in the livers of the C57BL/6J-db/db mice treated with CTL due to decreases in the phosphorylation of eIF2α, IRE1α, and IRS-1 serine and decreases in the mRNA expression of ATF4, c-Jun N-terminal kinase, C/EBPα, and C/EBP homologous protein. Dietary supplementation with CTL also induced a statistically significant decrease in the expression of pro-inflammatory cytokines, C-reactive protein (CRP), and NF-κB phosphorylation.
conclusionsOverall, these results suggest that CTL can improve hepatic insulin resistance and hyperglycemia by controlling obesity-induced ER stress and inflammation in the liver and that CTL may be a useful agent in treating hyperglycemia.
