Metabonomics of brain tissue in migraine rat model induced by nitroglycerin or cortical spreading depression

Abstract

This study analyzes the differences in potential biomarkers of migraine models constructed by two commonly used modeling methods through metabolomics research. Migraine models were constructed by nitroglycerin (NTG) induction or mechanical stimulus-induced cortical spreading depression (CSD) in rats. Multivariate analysis was used for metabolomic analysis. Compared with control group, NTG migraine group had 1 different metabolite up-regulated and 14 down-regulated. Compared with NTG migraine group, 13 differential metabolites in the CSD migraine model group were up-regulated and 12 were down-regulated. Both nitroglycerin-induced and mechanical stimulation-induced CSD can construct migraine rat models, and the biomarkers of the two models are different.
