a Representative western blots of APP in PITRM1+/+ and PITRM1−/− iPSC-derived cortical neurons. b Quantification of APP levels normalized to the loading control (mean + SEM; **p < 0.01, two-tailed t test, n = 5). c Quantification of Aβ species and the Aβ42/Aβ40 ratio in the supernatant of PITRM1+/+ and PITRM1−/− iPSC-derived cortical neurons at DIV 35, as performed by Meso Scale immunoassay (mean + SEM; *p < 0.05, ***p < 0.001, two-tailed t test, n = 5). d Gene expression levels of APP in PITRM1+/+ and PITRM1−/− iPSC-derived cortical neurons (mean + SEM; ***p < 0.001, two-tailed t test, n = 5). e Representative western blot of PITRM1+/+ and PITRM1−/− iPSC-derived neurons of total ubiquitinated protein levels. f Quantification of the protein ubiquitination level in PITRM1+/+ and PITRM1−/− iPSC-derived neurons (mean + SEM; **p < 0.01, two-tailed t test, n = 6).
