Exploring the epigenetic modifications of the RONS-TRPA1-CGRP axis in migraine pathophysiology.
Review in The journal of headache and pain, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundEpigenetic studies in migraine provided results on the occurrence or lack of epigenetic modifications of genes whose products are important in migraine pathogenesis. However, these studies focus on single genes without analyzing how epigenetic modifications can affect complex signaling pathways. This narrative/hypothesis review aims to provide information on how the reactive oxygen and nitrogen species (RONS)-transient receptor potential cation channel subfamily A member 1 (TRPA1)-calcitonin gene-related peptide (CGRP) axis functions, suggesting that its epigenetic modifications could be a significant factor in migraine pathophysiology. MAIN BODY: Oxidative stress is both a cause and a consequence of migraine, and reactive oxygen and nitrogen species (RONS), like other noxious stimuli, may activate the transient receptor potential cation channel subfamily A member 1 (TRPA1) to send pain signals. Methylation of the TRPA1 gene correlates with various pain states; however, the results of these studies are largely inconsistent. DNA methylation and the action of non-coding RNAs are important in the alternative RNA processing of the calcitonin-related polypeptide alpha (CALCA) gene and its transcript to produce calcitonin gene-related peptide (CGRP). The release of CGRP and substance P from trigeminal neuron terminals, mediated by TRPA1 activation and involving mitogen-activated protein kinase 1/2, is a primary mechanism driving migraine headaches. Epigenetic memory may be related to neural plasticity and migraine chronification. Therefore, the RONS-TRPA1-CGRP signaling pathways may be important in migraine pathogenesis, as demonstrated in experimental animals by the phenomenon of cortical spreading depolarization.
conclusionThe RONS-TRPA1-CGRP axis plays a significant role in the pathogenesis of migraine and other pain-related syndromes. Epigenetic modifications of the genes encoding the components of the antioxidant defense system, TRPA1 and CGRP, are crucial in migraine pathogenesis, prevention, and therapy. However, due to the sequence specificity of the axis, only non-coding RNAs can currently be considered for therapeutic intervention in migraine, targeting the epigenetic profile of the RONS-TRPA1-CGRP axis.
