Abstract

Glioblastoma is the most common and aggressive primary brain tumor and has a high mortality in humans. However, mechanisms and factors involved in the progression of glioblastoma remain elusive. WISP1 (WNT1 inducible signaling pathway protein 1), has been suggested to be a critical regulator of cancer development. The aim of this study was to investigate the role of WISP1 in regulating the progression of glioblastoma. Clinicopathological characteristics of glioblastoma were assessed, and higher levels of WISP1 were positively associated with advanced clinical stage and a poor prognosis. Consistently, WISP1 expression was significantly upregulated in glioblastoma tissue and cell lines compared with normal tissue and cells. Additionally, inhibition of WISP1 greatly suppressed cell proliferation, migration, and invasion and promoted apoptosis and cell cycle arrest of glioblastoma cells. Further study indicated that downregulation of WISP1 suppressed cell proliferation associated with the gene expression of c‑myc and cyclin D1 and cellular signaling such as through the ERK pathway, while inhibiting epithelial-mesenchymal transition and MMP9. Finally, knockdown of WISP1 markedly suppressed in vivo tumor growth and sensitized glioblastoma cells to temozolomide. This study identified WISP1 as an oncogene in glioblastoma and suggests that WISP1 may serve as a potential molecular marker and treatment target for glioblastoma.
