title: Expression of mitochondrial complex I subunit gene NDUFV2 in the lymphoblastoid cells derived from patients with bipolar disorder and schizophrenia.
abstract: Several studies have suggested mitochondrial abnormality in bipolar disorder (BD) and schizophrenia (SZ). We have previously reported the decreased expression of mitochondrial complex I subunit gene, NDUFV2 at 18p11, in lymphoblastoid cell lines (LCLs) from Japanese patients with bipolar I disorder (BDI). Recently it was reported that no differences were found in NDUFV2 mRNA levels in LCLs of Caucasian BDI patients compared with controls. In this study, we tested the altered expression of NDUFV2 in extended Japanese LCLs and LCLs from different ethnic groups. Similar tendency was found in the current study compared with our previous study, since decreased expression of NDUFV2 in LCLs from Japanese patients with BDI was found (p=0.03). We also found that the expressions of NDUFV2 were up-regulated in those from patients with Japanese bipolar II disorder (p=0.001) and the mRNA levels of this gene were down-regulated in Caucasian SZ (p=0.000001) compared with controls. Furthermore, we revealed that the mRNA expression of NDUFV2 in LCLs cultured with valproate, one of mood stabilizers, were significantly increased compared with controls (p=0.02). Our study presented the further evidence of biological significance of NDUFV2 in BD and SZ.
