Abnormal Histones Acetylation in Patients with Primary Sjögren's Syndrome.
Article in Clinical rheumatology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionAberrant histone acetylation is increasingly thought to play important roles in the pathogenesis of autoimmune diseases. However, there are very few data on histone acetylation in primary Sjögren's syndrome (pSS). We aimed to investigate whether there was abnormal histones acetylation in patients with pSS.
methodsWe investigated the expressions of histone acetyltransferase (HAT) genes (p300, CREBBP and PCAF) by real-time PCR in the peripheral blood mononuclear cells (PBMCs) of pSS patients. HAT activity and histone H3/H4 acetylation activity were measured by activity kit, and histone H3/H4 acetylation was verified by Western blot (WB). Spearman test was utilized to analyze the association between HAT activity levels and clinical parameters of pSS patients.
resultsThe mRNA expressions of p300, CREBBP and PCAF in PBMCs from pSS patients were decreased in comparison with healthy controls (P < 0.05). HAT activity and histone H3/H4 acetylation were reduced in PBMCs from pSS patients (P < 0.05). We found that HAT activity was negatively correlated with CRP (P = 0.040) and TNF-α (P = 0.012), and was positively correlated with C4 (P = 0.041).
conclusionsHistone hypoacetylation is observed in patients with pSS and is involved in the pathogenesis of pSS. KEY POINTS: • The mRNA expressions of p300, CREBBP and PCAF in PBMCs from pSS patients were decreased in comparison with HCs. • HAT activity and histone H3/H4 acetylation were reduced in PBMCs from pSS patients. • HAT activity was correlated with disease characters. • We show for the first time that the histone hypoacetylation may be involved in the pathogenesis of pSS.
