Budding uninhibited by benzimidazoles 1 promotes cell proliferation, invasion, and epithelial-mesenchymal transition via the Wnt/β-catenin signaling in glioblastoma

Open access

Abstract

The pathogenesis and progression of GBM (glioblastoma), as one of the most frequently occurring malignancies of the central nervous system, are regulated by several genes. BUB1 (budding uninhibited by benzimidazoles 1) is a mitotic checkpoint that plays an important role in chromosome segregation as well as in various tumors. However, its role in glioma is unknown. The current study discovered prominently elevated BUB1 in glioma and a significant relationship between BUB1 expression, a high World Health Organization grade, and a poor prognosis in glioma patients. Moreover, BUB1 triggered EMT (epithelial-mesenchymal transition) apart from promoting glioma cell proliferation, migration, and infiltration. Besides, BUB1 promoted EMT by activating the Wnt/β-catenin axis. As implied by our study, BUB1 probably has the potential as a target for GBM management.

Figures

Fig. 1 In the GBM (glioblastoma) tissues, BUB1 (budding uninhibited by benzimidazoles 1) was up-regulated, which was linked to a poor outcome. (A) Compared to the normal cerebral tissues, BUB1 was upregulated in the glioma (low-grade) and GBM tissues, according to the GEPIA (Gene Expression Profiling Interactive Analysis) database-based analysis. (B) The World Health Organization grade was linked to the BUB1 expression. (C–D) Overall survival plots for the glioma patients either highly or lowly expressing BUB1 (GEPIA and Chinese Glioma Genome Atlas databases). (E) Compared to the normal tissues, up-regulation of BUB1 was noted in the GBM tissues. (F) RT-PCR (real-time polymerase chain reaction) findings of BUB1 levels in the GBM (A172, LN229, T98G, U87, and U251) cells.

Fig. 2 BUB1 facilitated the in-vitro carcinoma proliferation in GBM cells. (A) Short-hairpin RNA against BUB1 was effectively transfected into U87 and U251 cells. (B) BUB1 knockdown in the U87 and U251 cell lines. (C) The viability of transfected U87 and U251 cells was determined using the Cell Counting Kit-8 assay. (D) Cloning capacity assessment of the transfected U87 and U251 cells was accomplished via the colony formation assay (**P < 0.01).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
