Dioscin regulates oxidative stress and autophagy in uric acid-induced HK-2 cells through the P62-KEAP1-NRF2 signaling 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
objectiveThis study aims to explore the therapeutic effects and mechanisms of dioscin on the UA-induced HK-2 cells fibrosis model by modulating oxidative stress and autophagy.
methodsHK-2 cells fibrosis was constructed by UA stimulation. CCK8 was used to assess cell proliferation. Flow cytometry was employed to detect apoptosis. MDC staining was performed to observe the formation of autophagosomes. Western blot was used to evaluate the levels of oxidative stress, autophagy and fibrosis markers. The detection of ROS and Elisa assay were used to analyze the changes of oxidative stress.
resultsDioscin significantly inhibits cell apoptosis. Dioscin increases the expression of LC3, Beclin-1 and NRF2 and decreases the expression of P62 and KEAP1. Furthermore, dioscin inhibits the levels of ROS and MDA, and promotes the levels of SOD and CAT. Moreover, dioscin significantly downregulates the expression of TGF-β, FN, and Collagen I. However, the regulatory effects of dioscin on these indicators are inhibited when NRF2 is knocked down.
conclusionThese results suggest that dioscin treats the UA-induced HK-2 cells fibrosis model by targeting the modulation of NRF2 to regulate oxidative stress and promote protective autophagy. The mechanism may be associated with the restoration of the P62-KEAP1-NRF2 signaling pathway.
