Lower protein levels of BDNF in both adult and pediatric patients with MDD compared with controls. |
Cattaneo et al. 2010a [46] | Case-control and follow up | 21 MDD 23 Controls | BDNF | Diagnosis based on DSM-IV or ICD-10 criteria MADRS | Lower expression of BDNF in patients with MDD compared with controls. Significant increase in expression of BDNF after escitalopram treatment as well as symptom improvement. |
Cattaneo et al. 2010b [48] | Case-control and follow up | 25 MDD 25 Controls | VGF | Diagnosis based on DSM-IV or ICD-10 criteria MADRS | Lower expression of VGF in patients with MDD compared with controls. Significant increase in expression of VGF after 12 weeks of escitalopram treatment in responders only. |
Cattaneo et al. 2012 [23] | Case-control and follow up | 74 MDD 34 Controls | BDNF VGF | Diagnosis based on DSM-IV or ICD-10 criteria SCAN | Lower expression of BDNF and VGF in patients with MDD compared with controls. Significant increase in BDNF and VGF expression after 8 weeks of antidepressant treatment (escitalopram or nortriptyline) in responders only. |
Otsuki et al. 2008 [49] | Case-control | 60 MDD 42 BPD 28 Controls | BDNF NGF NT-3 NT-4 GDNF ARTN NRTN PSPN | Diagnosis based on DSM-IV criteria HDRS | Lower expression of GDNF, ARTN and NT-3 in patients with MDD in a current depressive state compared with those in remission and controls. No significant difference in expression of GDNF, ARTN or NT-3 in patients with BPD. No significant difference in expression levels of BDNF, NGF or NT-3 among the three groups. |
Su et al. 2009 [54] | Case-control | 16 MDD 14 Controls | p11 | Diagnosis based on DSM-IV criteria MINI HAM-D HARS | Higher expression of p11 in patients with MDD compared with controls. |
Zhang et al. 2011 [55] | Case-control | 38 BPD 14 Controls | p11 | Diagnosis based on DSM-IV criteria MINI HDRS-17 YMRS | Higher expression of p11 in patients with BPD compared with controls. |
Iga et al. 2007 [57] | Case-control | 42 MDD 32 Controls | VEGF | Diagnosis based on DSM-IV criteria SIGH-D 17 | Higher expression of VEGF in patients with MDD compared to controls. |
Dome et al. 2009 [58] | Case-control | 33 MDD 16 Controls | CD34 CD133 VEGFR2 | Diagnosis based on DSM-IV criteria BDI | Lower expression of VEGFR2 and CD133 in patients with MDD compared with controls. Expression of VEGFR2 and CD133 correlated negatively with BDI scores. |
Anitha et al. 2008 [59] | Case-control | 33 MDD 21 BPD 57 Controls | PCNT2 | Diagnosis based on DSM-IV criteria BPRS HAM-D | Higher expression of PCNT2 in patients with MDD compared with controls. Higher expression of PCNT2 in patients with BPD in a remission state compared with controls. |
Nakataki et al. 2011 [60] | Case-control | 27 MDD 27 Controls | EMP1 | Diagnosis based on DSM-IV criteria HAM-D | Lower expression of EMP1 in patients with MDD compared with controls. A trend increase in expression of EMP1 after 8 weeks of antidepressant treatment |
Wakabayashi et al. 2008 [64] | Case-control | 60 MDD 42 BPD 28 Controls | NCAM-140 L1 VCAM-1 ICAM-1 E-cadherin | Diagnosis based on DSM-IV criteria HDRS | Lower expression of NCAM-140 in patients with BPD in a current depressive state, but not in a remissive state, compared with controls and patients with MDD. Higher expression of L1 in patients with BPD in a current depressive state, but not in a remissive state, compared with controls and patients with MDD. No significant differences in expression of NCAM-140 or L1 in patients with MDD compared with controls. No significant differences in expression of ICAM-1, VCAM-1 or E-cadherin in patients with MDD or BPD in a current depressive state compared to controls. |
Otsuki et al. 2010 [68] | Case-control | 60 MDD 46 BPD 28 Controls | REST CRH 5-HT1A Adcy5 CaMKIIa Epor IGF1R Tnfsf10 Tnfsf11 Tnfsf12-12 | Diagnosis based on DSM-IV criteria HDRS | Lower expression of REST in patients with MDD compared with controls. Higher expression of CRH, Adcy5 and Tnfsf12-13 in patients with MDD in a current depressive state compared with those in a remissive state. No significant difference in expression of REST or any other mRNAs in patients with BPD compared with controls. |
