REL and bipolar disorder: Bipolar disorder subjects had higher mean mRNA levels for NF-κB2 (+51%; F(1,67) = 10.1, p = 0.018; Fig. 2), RelA (+14%; F(1,67) = 8.8, p = 0.029), and cRel (+12%; F(1,67) = 6.9, p = 0.042), but not NF-κB1 (+6%; F(1,67) = 2.1, p = 0.15) or RelB (+7%; F(1,68) = 1.2, p = 0.28), relative to unaffected comparison subjects.
