HOMER1 and Behcet disease: Furthermore, we measured the expression of circHomer1a and linear HOMER1 mRNA in a large subset of iPS cell-derived neuronal progenitors (NPs) and 6-week differentiated neurons from early onset SCZ patients and controls (n = 9 patients/10 controls) [56], and in iPS cell-derived NPs and neuronal cultures from patients with BD and unaffected controls [10] that were differentiated for 2, 4, and 6 weeks (n = 4 patients and 3 controls for each developmental stage) (Fig. 2e–h).
