Effect of tubastatin A on NLRP3 inflammasome activation in macrophages under hypoxia/reoxygenation conditions.

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
backgroundThere are currently no effective drugs to mitigate the ischemia/reperfusion injury caused by fluid resuscitation after hemorrhagic shock (HS). The aim of this study was to explore the potential of the histone deacetylase 6 (HDAC6)-specific inhibitor tubastatin A (TubA) to suppress nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome activation in macrophages under hypoxia/reoxygenation (H/R) conditions.
methodsThe viability of RAW264.7 cells subjected to H/R after treatment with different concentrations of TubA was assessed using a cell-counting kit-8 (CCK8) assay. Briefly, 2.5 μmol/L TubA was used with RAW264.7 cells under H/R condition. RAW264.7 cells were divided into three groups, namely the control, H/R, and TubA groups. The levels of reactive oxygen species (ROS) in the cells were detected using fluorescence microscopy. The protein expression of HDAC6, heat shock protein 90 (Hsp90), inducible nitric oxide synthase (iNOS), NLRP3, gasdermin-D (GSDMD), Caspase-1, GSDMD-N, and Caspase-1 p20 was detected by western blotting. The levels of interleukin-1β (IL-1β) and IL-18 in the supernatants were detected using enzyme-linked immunosorbent assay (ELISA).
resultsHDAC6, Hsp90, and iNOS expression levels were significantly higher (
conclusionTubA inhibited the expression of HDAC6, Hsp90, and iNOS in macrophages subjected to H/R. This inhibition led to a decrease in the content of ROS in cells, which subsequently inhibited the activation of the NLRP3 inflammasome and the secretion of IL-1β and IL-18.
