The complex effects of combined CDki/SPyADI application on arginine-auxotrophic glioblastoma multiforme cells. CDki/SPyADI combination therapy impairs cell proliferation, invasiveness, gene expression, induces mitochondrial impairment, and vacuole formation. Abemaciclib-SPyADI-treatment suppresses DNA repair, dinaciclib-SpyADI-treatment enhances γ-H2AX accumulation and activates the stress sensor GADD45 and β-catenin antagonist AXIN2. Both CDKi/SpyADI combinations significantly boost cell death.
