LASP1 and glioblastoma: To determine the underlying mechanism of LASP1 in regulating proliferation and TMZ chemoresistance, we analyzed glioblastoma data in TCGA database (TCGA, Cell 2013) by using cBioPortal tools (http://www.cbioportal.org/index.do) and found that phosphorylated AKT3 at Ser 473 was positively correlated with the LASP1 mRNA level, but the total level of AKT3 was not significantly correlated with LASP 1 (Fig. 5a).
