The promoting effect and mechanism of MAD2L2 on stemness maintenance and malignant progression in glioma

View Original View Raw

Summary

This study aimed to investigate the molecular mechanisms behind glioblastoma stem cell (GSC) maintenance and progression. Through bioinformatics analysis, MAD2L2 was found to be highly expressed in glioblastoma samples and was shown to have a significant correlation with patient prognosis. In vitro and in vivo experiments confirmed that silencing of MAD2L2 led to decreased proliferation, invasion, and migration capabilities of glioblastoma cells, while decreasing stemness characteristics of GSCs. Overexpression of MAD2L2 enhanced these malignant behaviors, and further investigation revealed that the c-MYC proto-oncogene mediated the functional role of MAD2L2 in glioblastoma. Additionally, E2F-1 was found to be a transcription factor that regulates MAD2L2 expression. These findings suggest that MAD2L2 may be a potential therapeutic target for treating glioblastomas.

Q&As

What is the role of Mitotic arrest deficient 2 like 2 (MAD2L2) in glioma?
The role of Mitotic arrest deficient 2 like 2 (MAD2L2) in glioma is to maintain glioblastoma stemness and promote malignant behaviors.

What is the impact of MAD2L2 on glioblastoma cell behaviors?
The impact of MAD2L2 on glioblastoma cell behaviors is decreased proliferation, invasion, and migration capabilities, while decreasing stemness characteristics of glioblastoma stem cells. Conversely, overexpression of MAD2L2 enhances these malignant behaviors.

How does silencing and overexpression of MAD2L2 affect glioblastoma stemness characteristics?
Silencing of MAD2L2 leads to decreased stemness characteristics of glioblastoma stem cells, while overexpression of MAD2L2 enhances these stemness characteristics.

What role does c-MYC play in the functional role of MAD2L2 in glioblastoma?
c-MYC mediates the functional role of MAD2L2 in glioblastoma, which was further validated through a rescue experiment.

How is the expression of MAD2L2 regulated by upstream transcription factors?
The upstream transcription factor E2F-1 regulates the expression of MAD2L2, which was determined through dual-luciferase reporter assays and ChIP assays.
