There has been only one report analyzing whole blood transcriptome (WBT) in menstrual migraine.


To investigate interictal WBT in patients suffering from migraine with aura (MWA).


We performed 52 RNA-seq experiments with 26 controls (20 females) and 26 interictally-drawn samples (20 females) from sex- and age-adjusted patients suffering from MWA using Illumina Hi-seq high-throughput sequencing machine. To detect differentially expressed (DE) genes between affected and unaffected samples we used the edgeR (robust dispersion estimation) software correcting by sex.


We obtained more than 100 million short reads per sample. We identified 93 up-regulated genes in unffecteds, and 7 up-regulated genes in affecteds (FDR< 5%). Interestingly, among those DE genes we found some related to endothelial function (HBG1, HBG2, and ADIPOR1), and other related to solute carriers, energetic mechanisms, and apoptosis were also found up-regulared in controls; overexpression of genes involved in inflamation were found in affecteds. We also performed a gene ontology enrichment for the differentially expressed genes (DAVID database) and found eritrocyte and myeloid differentiation processes to be significant (Bonferroni <0.1). Other gene ontologies, like apoptosis or positive regulation of synaptic transmission, showed uncorrected significant P values (<0.05).


Our preliminary results after analyzing WBT found 100 differentially expressed genes in MWA. The most significantly DE genes are involved in endothelial homeostasis. These results open new targets for understanding migraine pathophysiology.
