Altered ANRIL Methylation in Epileptic Patients.
Article in Journal of molecular neuroscience : MN, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Long non-coding RNAs (lncRNAs) have regulatory roles in several aspects of cellular physiology. Recent studies have also revealed their role in neuronal differentiation and the pathophysiology of neurologic disorders such as epilepsy. We have recently reported altered expression of a number of lncRNAs in the peripheral blood of epileptic patients in association with their response to antiepileptic drugs. One the most significantly altered lncRNAs in epileptic patients is the antisense non-coding RNA in the INK4 locus (ANRIL), whose expression has been found to be higher in both refractory and non-refractory groups compared with controls. In the current study, we aimed to identify the methylation status of this lncRNA to suggest a potential mechanism for deregulated ANRIL expression. Thus, we assessed the methylation status of the ANRIL promoter in 40 patients with refractory epilepsy, 40 patients with non-refractory epilepsy and 40 normal controls using the high-resolution melting (HRM) method. The HRM results showed hypomethylation of the ANRIL promoter region in both refractory epilepsy and non-refractory epilepsy patients compared with normal controls. This methylation pattern was consistent with the recently reported upregulation of this lncRNA in patients with epilepsy. Thus, we suggest altered methylation of the ANRIL promoter as a potential cause of its aberrant expression in peripheral blood of epileptic patients.
