Background

Gliomas are the most malignant and aggressive form of brain tumors, and account for the majority of brain cancer related deaths. Previous studies have reported that SUB1 serves as a novel RBP, which is highly expressed in tumors.

Aim

In our research, we aimed at exploring the regulatory mechanism of SUB1 in glioma cells.

Methods

RT-qPCR was conducted to measure the expression of SUB1, HSP90β and MYC in glioma cells in U87 cell. Cell function tests were conducted to identify how the ectopic SUB1 expression influenced the proliferation and migration of glioma cells. Also, functional assays and mechanism experiments were carried out to figure out the relationship among circVCAN, SUB1 and MYC/HSP90β.

Results

SUB1 expression was up-regulated in glioma cells. The inhibition of SUB1 expression suppressed the proliferation and migration of glioma cells, while the up-regulation of that accelerated the proliferation and migration of glioma cells. CircVCAN could up-regulate the expression of MYC/HSP90β by recruiting SUB1, thereby promoting glioma progression.

Conclusion

SUB1 plays a significant role in the survival and migration of glioma cells."xsd:string
