mRNA level of N-methyl-D-aspartic acid receptor NR1 subunit in patients with major depressive disorder and its relationship with clinical features].

Objective: To investigate the characteristics of glutamatergic neurotransmitter and neurotransmission dysfunction in patients with major depressive disorder (MDD) and its relationship with clinical characteristics. Methods: Fifty-two patients with MDD and 51 healthy controls were selected. Hamilton Depression scale-17 (HAMD-17) and Hamilton Anxiety Scale (HAMA) were used to evaluate the symptoms of depression and anxiety. The serum glutamate level was measured by enzyme-linked immunosorbent assay (ELISA). Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the mRNA level of NR1 subunit of NMDA receptor. Results: There was no significant difference in gender and age between MDD group and healthy control group. Compared with the control group, the level of serum glutamate [(35±6) mg/L vs (29±6) mg/L, P = 0.021] and mRNA level of NR1 (1.5±0.8 vs 0.8±0.6, P = 0.001) in MDD group were significantly higher. In MDD group, serum glutamate level was positively correlated with depression core symptom score (r = 0.52, P = 0.028), and mRNA level of NR1 subunit was positively correlated with the total course of disease (r = 0.42, P = 0.024). Conclusion: MDD patients may have disorder of glutamatergic neurotransmitter and abnormal expression of NR1 subunit.
