We then used a human neuroblastoma cells (M17) stably over-expressing alpha-synuclein and found that RAC1 function decreased the amount of amyloidogenic alpha-synuclein.
Given that Rac1 GTPase has been suggested to mediate the switch between elongated and rounded invasion, the functionality of the Rac1 morphology switch was evaluated in the glioma and neuroblastoma cells.
We studied all trans-retinoic acid (RA) signaling in neuroblastoma cells differing in N-myc levels in terms of neurite formation, expression of tissue transglutaminase, neuronal marker proteins, matrix metalloproteinases (MMPs), and activation of Rac1 and Cdc42.
