Spontaneous Regional Brain Activity in Healthy Individuals is Nonlinearly Modulated by the Interaction of ZNF804A rs1344706 and COMT rs4680 Polymorphisms / 神经科学通报·英文版

ZNF804A rs1344706 has been identified as one of the risk genes for schizophrenia. However, the neural mechanisms underlying this association are unknown. Given that ZNF804A upregulates the expression of COMT, we hypothesized that ZNF804A may influence brain activity by interacting with COMT. Here, we genotyped ZNF804A rs1344706 and COMT rs4680 in 218 healthy Chinese participants. Amplitudes of low-frequency fluctuations (ALFFs) were applied to analyze the main and interaction effects of ZNF804A rs1344706 and COMT rs4680. The ALFFs of the bilateral dorsolateral prefrontal cortex showed a significant ZNF804A rs1344706 × COMT rs4680 interaction, manifesting as a U-shaped modulation, presumably by dopamine signaling. Significant main effects were also found. These findings suggest that ZNF804A affects the resting-state functional activation by interacting with COMT, and may improve our understanding of the neurobiological effects of ZNF804A and its association with schizophrenia.

Gender differences of plasma glial cell line-derived neurotrophic factor levels in patients with major depressive disorder / 中华行为医学与脑科学杂志

Objective To investigate gender differences of plasma glial cell line-derived neurotro-phic factor (GDNF) levels in patients with major depressive disorder (MDD). Methods MDD subjects (male 20,female 36) and healthy controls (HCs) (male 35,female 45) were divided into four groups by gender. Plasma levels of GDNF were measured and compared in different gender groups. The clinical symp-tom severity of MDD patients was evaluated by 17-item Hamilton Depression Scale (HAMD-17) and Hamil-ton Anxiety Scale (HAMA-17). Results (1)The plasma GDNF level in male patients with major depres-sive disorder (( 1. 55 ± 0. 43 ) pg/ml ) was significantly lower than that in healthy controls (( 1. 86 ± 0. 50)pg/ml,F=4. 64,P=0. 036). There was no significant difference in GDNF level between female de-pression patients((1.62±0.46)pg/ml)) and female healthy control((1. 64±0. 48)pg/ml,F=0. 18,P=0. 672). In HCs,the GDNF level of male was significantly higher than that of female((1. 86±0. 50)pg/ml, (1. 64±0. 48)pg/ml,F=2. 04,P=0. 045). There was no significant difference in GDNF level between male and female patients(P>0. 05). (2) GDNF level in male patients with major depressive disorder was nega-tively correlated with HAMA score(r=-0. 388,P=0. 034). Conclusion The expression of GDNF is affect-ed by sex factors,which may be related to the different pathogenesis of MDD.
