Regardless the obtention of the unanticipated triarylmethane instead of pMb, THTMP presents a positive effect at GBM cytotoxicity level.20 Our investigation of cellular mechanisms reveals that THTMP treatment disrupts epidermal growth factor receptor (EGFR) pathways by modulation of genes encoding downstream mediators,23 leading to a reduction of the cell proliferation and migration. The gene discussed is EGFR; the disease is glioblastoma.
