APOE and glioblastoma: In addition, the cellular uptake of ApoE-rHDL in glioblastoma cellswas largely inhibited by the inhibitors of macropinocytosis, amiloride andethylisopropylamiloride (EIPA), indicating that macropinocytosis might serve as a uniquemechanism for the glioblastoma-specific accumulation of ApoE-rHDL.
