G3BP1 and astrocytoma (excluding glioblastoma): We next performed a compound screen to identify compounds that can inhibit CLM-and NU7441-induced formation of FUSP525L-positive SGs without changing the formation of G3BP1-positive SGs as the 1st screen using mCherry-G3BP1-and Venus-FUSP525L-expressing U251 MG (KO) astrocytoma cell lines.
