Glioblastoma multiforme (GBM), one of the most aggressive human malignant brain
tumors, is induced by multiple complex pathological mechanisms. The main cause of
mortality in patients with GBM is the invasion-metastasis cascade of tumor cells.
The dysfunction of Parkinson protein 2 E3 ubiquitin protein ligase (PARK2) is
closely linked with the development of certain human cancers. However, whether
PARK2 is associated with metastasis in GBM remains unknown. The present study
demonstrated that the metastasis and invasion of U87 cells were significantly
repressed by PARK2 overexpression. Conversely, knockdown of PARK2 facilitated the
metastasis and invasion of A172 cells. Furthermore, PARK2 downregulated zinc
finger E-box-binding homeobox 1 (ZEB1) expression and mitigated
epithelial-mesenchymal transition (EMT). Promoter effects of PARK2 knockdown on
cell metastasis and EMT were antagonized by silencing ZEB1 expression. These
results indicated that PARK2 participated in regulating the invasion-metastasis
cascade of cancer cells by depressing ZEB1 expression and acting as a metastasis
suppressor in GBM progression, providing a potential therapeutic approach for GBM
treatment.
