PRKCA and glioblastoma: One study has evaluated KPF action in vitro using the GBM cell line GBM8401 exposed to 12-otetradecanoylpholia-13-acetate (TPA) at 5, 10, 20, and 40 μM, a MMP9 inducer activity, and consequent cell migration and invasion through kinase C α protein (PKCα), extracellular signal-regulated kinases (ERK), and NF-kB pathways activation.
