Since T98G glioblastoma cells mainly express the M87-Spastin isoform (Figure 6A), to analyze the role of M87-Spastin in detail and compare the isoforms, we cloned the wild-type (SpastinM87) and mutant (SpastinM87_mutA and SpastinM87_mutD) M87-Spastin constructs (Figure 1) expressing only the M87-Spastin isoform (Figure S1). The gene discussed is SPAST; the disease is glioblastoma.
