FRMD6 and glioblastoma: After selection of the infected cells with puromycin, pooled populations of the drug-resistant U87MG/U251 cells express v5-epitope tagged FRMD6 (FRMD6v5, Figure 2A) at the levels that are similar to those of endogenous FRMD6 expressed by normal human astrocytes or certain GBM cells (Figure 1A, lane 1, 15).
