Evaluation of the antioxidant effects of different histone deacetylase inhibitors (HDACis) on human lens epithelial cells (HLECs) after UVB exposure.
Article in BMC ophthalmology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundTo compare the protective effects of the histone deacetylase inhibitors (HDACis) β-hydroxybutyrate (βOHB), trichostatin A (TSA), suberoylanilide hydroxamic acid (SAHA) and valproic acid (VPA) on human lens epithelial cells(HLECs) following ultraviolet-B (UVB) exposure.
methodsHLECs were divided into subgroups: four HDACi groups, a control group, a UVB-treated group and a DMSO group (cells treated with DMSO and UVB irradiation). In the HDACi groups, HLECs were cultured with different concentrations of HDACis 12 h prior to UVB irradiation. The protective effects of the HDACis were evaluated by assessing apoptosis rates, cell activity and expression levels of genes associated with apotosis (caspase-3, Bcl-2, BAX, SOD1, FOXO3A and MT2). The levels of superoxide dismutase (SOD), reactive oxygen species (ROS), malondialdehyde (MDA) and total antioxidant capacity (T-AOC) were detected in order to evaluate oxidative stress.
resultsThe results showed that SAHA (1 μmol/L, 2 μmol/L) and TSA (0.2 μmol/L) had mild protective effects on cell viability. βOHB (4 mmol/L) and TSA (0.2 mol/L) demonstrated protective effects on BCL-2 expression. TSA (0.2 mol/L) showed protective effects on SOD1 expression. TSA (0.2 mol/L) and SAHA (1 μmol/L) suppressed BAX and caspase-3 expression. TSA (0.2 mol/L, 0.8 mol/L) and SAHA (1 μmol/L, 2 μmol/L) suppressed the expression of FOXO3A and MT2. SOD levels were increased after treatment with βOHB (4 mmol/L), SAHA (8 μmol/L) and TSA (0.1 mol/L, 0.2 mol/L). T-AOC levels were increased in UVB-treated HLECs after treatment with SAHA (2 μmol/L). MDA levels decreased in UVB-treated HLECs following treatment with TSA (0.2 mol/L, 0.8 mol/L). ROS levels decreased in UVB-treated HLECs following treatment with βOHB (4 mmol/L), SAHA (1 μmol/L, 2 μmol/L) and TSA (0.2 mol/L). Western blotting results demonstrated that SOD1 levels significantly increased in the βOHB (4 mmol/L), SAHA (1 μmol/L, 2 μmol/L), TSA (0.1 mol/L, 0.2 mol/L) and VPA (5 mmol/L) groups. Only SAHA (1 μmol/L) had an anti-apoptotic effect on UVB-treated HLECs.
conclusionsOur findings indicate that low concentrations of HDACis (1 μmol/L of SAHA) mildly inhibit oxidative stress, thus protecting HLECs from oxidation. These results may suggest that there is a possibility to explore the clinical applications of HDACis for treatment and prevention of cataracts.
