To further investigate the epigenetic effects of Myc inhibition by Omomyc in glioblastoma cells, we analysed the expression of several histone modifications upon Omomyc induction by doxycycline in U87MG cells infected with a lentivirus encoding a Flag-Omomyc (FO; U87MG/FO) fusion protein. This evidence concerns the gene MYC and glioblastoma.
