Graph shows the average velocity of HcT-containing organelles treated with Capivasertib or Ipatasertib (10 nM) for 30 min compared to controls (DMSO: 483 endosomes, 34 axons, 41,897 movements; Capivasertib: 658 endosomes, 43 axons, 49,841 movements; Ipatasertib: 605 endosomes, 32 axons, 41,485 movements) (** P=2 x10-16, One-way ANOVA, Tukey's post-hoc test: DMSO-Capivasertib and DMSO-Ipatasertib *** P <0.0001; N=6 independent experiments, boxplot shows median, first and third quartiles. Upper/lower whiskers extend to 1.5 * the interquartile range). Percent of time HcT-containing organelles pausing per axon. Treatment with Ipatasertib and Capivasertib reduced the amount of time organelles spent pausing (* P=1.14 x10-7, One-way ANOVA, Tukey's post-hoc test: DMSO-Capivasertib P= 9.37x10-5, DMSO-Ipatasertib P= 2 x10-7; data shown are mean ± SEM, N=6 independent experiments).
