The sensitivity of human glioblastoma cells to virus-mediated oncolysis was investigated on five patient-derived cell lines. Primary glioblastoma cells (Gbl13n, Gbl16n, Gbl17n, Gbl25n, and Gbl27n) were infected with tenfold serial dilutions of the Leningrad-3 strain of the mumps virus, and virus reproduction and cytotoxicity were monitored for 96-120 h. Immortalized human non-tumor NKE cells were used as controls to determine the virus specificity.

Available systemic treatment options are few and ineffective, so new approaches to therapies for glioblastoma are in high demand. In total, 131 patients with diffuse glioma were studied.

A key feature of glioblastoma is the high level of inter- and intratumor heterogeneity that accounts for treatment resistance. Our aim was to investigate whether intratumor heterogeneity is maintained in cell models.

These tumors exhibit overlapping clinical and histological features. Mutations in genes serve as important diagnostic markers of tumor type, particularly chondrosarcoma.

Here we demonstrated the oncolytic potential of the L-16 vaccine strain of measles virus (MV) against primary human GBM cells and characterized the genetic patterns that determine the sensitivity of primary human GBM cells to oncolytic therapy. MV replicated in all GBM cells, and seven out of eight cell lines underwent complete or partial oncolysis.
