Furthermore, a closer look at the MMP’s expression profile revealed that the most abundant transcripts in infected GBM cells were MMP1, MMP2, MMP3, and MMP14, while the MMP3 expression level correlated with sensitivity to MV-induced oncolysis in all cell line tested (particularly in Gbl12n it was not detected) highlighting the potential role of MMPs in productive replication of MV L-16 (Figure 16). Here, MMP14 is linked to glioblastoma.
