VASH1 and glioma: In order to further explore the biological role of VASH1 in glioma cells, we first detected VASH1 expression in three human glioma cell lines (A-172, U-251, and U-87) and screened according to the results by Western-Blot and qPCR, and then established the human glioma cell line knocked out by VASH1 and analyzed the effect of low expression of VASH1 on the biological activity of glioma cells.
