CBX7, a member of the Polycomb-group proteins, plays a significant role in normal
and cancerous tissues and has been defined as a tumor suppressor in thyroid,
breast and pancreatic cancers. However, its function in glioma remains undefined.
CBX7 expression is decreased in glioma, especially in higher grade cases,
according to data in the CGGA, GSE16001 and TCGA databases. Further experimental
evidence has shown that exogenous CBX7 overexpression induced apoptosis and
inhibited cell proliferation, colony formation and migration of glioma cells. In
this study, we show that the invasive ability of glioma cells was decreased
following CBX7 overexpression and CBX7 overexpression was associated with
Wnt/?-catenin pathway inhibition, which also decreased downstream expression of
ZEB1, a core epithelial-to-mesenchymal transition factor. This reduction in Wnt
signaling is controlled by DKK1, a specific Wnt/?-catenin inhibitor. CBX7
enhances DKK1 expression by binding the DKK1 promoter, as shown in Luciferase
reporter assays. Our data confirm that CBX7 inhibits EMT and invasion in glioma,
which is manifested by influencing the expression of MMP2, MMP9, E-cadherin,
N-cadherin and Vimentin in LN229, T98G cells and primary glioma cells (PGC).
Furthermore, as a tumor suppressor, CBX7 expression is pivotal to reduce tumor
invasion and evaluate prognosis.
