Bcl-2 and the short isoform of c-FLIP, two proteins which can inhibit TRAIL-triggered cellular apoptosis, appear to mediate the sensitization effect of myricetin in glioblastoma cells, as their expression can be down-regulated by myricetin incubation (50 μM), and their overexpression can abrogate the facilitation effect of myricetin on TRAIL-induced apoptosis of glioblastoma cells (Siegelin et al., 2009). This evidence concerns the gene CFLAR and glioblastoma.
