Furthermore, we found NF-κB2 mRNA levels were correlated with mRNA levels for RelA (r = 0.83, p < 0.00001) and cRel (r = 0.74, p < 0.00001) across all subjects, as well as in either bipolar disorder subjects alone (all r ≥ 0.75, all p < 0.00001) or comparison subjects alone (all r ≥ 0.45, all p < 0.007; Table 2). Here, REL is linked to bipolar disorder.
