We measured the expression of BDNF mRNA and BDNF-AS mRNA in iPSC and NSC from bipolar disorder (BD) patients and healthy control subjects, and postmortem brain samples such as the corpus callosum, the Brodmann area (BA8), and BA46 from BD patients and age- and ***-matched controls. The expression of BDNF mRNA in iPSC from BD patients (n=6) was significantly lower than that of control subjects (n=4) although the expression of BDNF mRNA in NSC from BD patients was significantly higher than that of control subjects. In contrast, there were no changes in the expression of BDNF-AS mRNA in both iPSC and NSC between two groups. The expression of BDNF mRNA in the BA46 from BD patients (n=35) was significantly lower than that of controls (n=34) although the expression of BDNF mRNA in the corpus callosum and BA8 was not different between two groups (n=15). In contrast, there were no changes in expression of BDNF-AS mRNA in the three brain regions between two groups. Interestingly, there were significant positive correlations between BDNF mRNA expression and BDNF-AS mRNA expression in the postmortem brain samples. Sample sizes are relatively low. Our data suggest that abnormalities in the expression of BDNF, but not BDNF-AS, play a role in the pathogenesis of BD. Our data suggest that abnormalities in the expression of BDNF, but not BDNF-AS, play a role in the pathogenesis of BD. Hoarding disorder (HD) affects approximately 2.5% of the general population, leads to significant distress and impairment, and is notoriously difficult to treat. The crux of developing effective treatments for HD is our ability to reliably and validly measure relevant constructs in HD to better understand its presentation and, subsequently, formulate appropriate interventions.
