Endoplasmic reticulum stress induces renal fibrosis in high‑fat diet mice via the TGF‑β/SMAD pathway.

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
The aim of the present study was to investigate the role and mechanism of endoplasmic reticulum stress (ERS) in kidney injury caused by high‑fat diet (HFD). An obese mouse model was established via HFD feeding and intervention was performed by intraperitoneal injection of the ERS inhibitor salubrinal (Sal). Changes in the body and kidney weight and serum biochemical indices of the mice were determined. Hematoxylin and eosin and Masson staining were used to observe the pathological changes of renal tissues. Reverse transcription‑quantitative PCR and western blotting were used to observe the expression of ERS‑related proteins and TGF‑β/SMAD pathway‑related proteins. Immunohistochemistry was employed to explore the distribution of these proteins. Compared with those in the control group, the weight gain, lipid metabolism disorders and deterioration of renal function in the model group were greater. Malondialdehyde was elevated and superoxide dismutase was decreased in renal tissues. The mRNA and protein levels of TGF‑β1, SMAD2/3, α‑smooth muscle actin, collagen I, glucose‑regulated protein 78 and C/EBP‑homologous protein were markedly elevated, whereas SMAD7 was markedly decreased. Sal markedly inhibited the aforementioned effects. This investigation revealed a link between ERS and renal injury caused by HFD. ERS in HFD‑fed mice triggers renal fibrosis through the TGF‑β/SMAD pathway.
