Effect of P. harmala on AlCl₃-induced alterations in hippocampal (a) Aβ42, (b) p-tau, and (c) pS9-GSK-3β in AD rat model. Values represent mean ± SD (n = 6/4). The blots of p-tau and β-actin were cropped and the full-length blots are shown in the Supplementary file (Fig. S1). Statistical analysis was carried out by one-way ANOVA followed by Tukey’s Multiple Comparisons test. Significantly different from (*) CONT and (@) AlCl₃ groups at p < 0.05; AlCl₃ aluminum chloride, CONT control, Aβ42 amyloid beta 42, AU arbitrary units, pS9-GSK-3β phosphorylated glycogen synthase kinase-3 beta at serine 9, Ph Peganum harmala, p-tau phosphorylated tau.
