Tryptophan hydroxylase 2 gene polymorphisms in Japanese patients with medication overuse headaches.

Purpose: We investigated whether tryptophan hydroxylase 2 (TPH2) gene polymorphisms were involved in the aggravation of migraines due to the overuse of medication.

Methods: Forty-seven migraine patients (6 males and 41 females; 36.4 10.

Association between the G252A Tumor Necrosis Factor-β Gene Polymorphism and Medication-Overuse Headache.

Background And Purpose: Migraine patients are particularly prone to the complication of medication-overuse headache (MOH). Although it has been shown that A allele carriers for the tumor necrosis factor (TNF)-β gene G252A polymorphism are at high risk of the development of migraine without aura, the relationship between the TNF-β gene G252A polymorphism and MOH is unknown. We investigated whether the TNF-β gene G252A polymorphism is involved in the aggravation of migraine by overuse of medications.

Predictive index for the onset of medication overuse headache in migraine patients.

Migraine patients are particularly prone to develop medication overuse headache (MOH). However, the risk factors for the transformation of migraine to MOH are still not clear. We investigated gene polymorphisms, personality traits, and characteristics of headache and lifestyle in 47 migraine patients (aged 36.

MAOA, MTHFR, and TNF-β genes polymorphisms and personality traits in the pathogenesis of migraine.

Migraine is a multifactorial disease with various factors, such as genetic polymorphisms and personality traits, but the contribution of those factors is not clear. To clarify the pathogenesis of migraine, the contributions of genetic polymorphisms and personality traits were simultaneously investigated using multivariate analysis. Ninety-one migraine patients and 119 non-headache healthy volunteers were enrolled.

Mitochondrial complex I activity is significantly decreased in a patient with maternally inherited type 2 diabetes mellitus and hypertrophic cardiomyopathy associated with mitochondrial DNA C3310T mutation: a cybrid study.

Mitochondrial respiratory function in a patient with maternally inherited type 2 diabetes mellitus and hypertrophic cardiomyopathy associated with heteroplasmic mitochondrial DNA (mtDNA) C3310T mutation, which replaces the second amino acid of NADH dehydrogenase 1 (ND1) from a hydrophobic Proline to a hydrophilic Serine, was investigated. Mitochondrial respiratory function solely due to mtDNA C3310T mutation was investigated in cybrid system by the fusion of mtDNA-deleted (rho(0)) HeLa cells and exogenous mtDNA either from the proband or from controls. Total oxygen consumption of the proband cybrid cells was significantly decreased compared with those of controls (2.
