Interestingly, in contrast to these later mentioned “bad responders”, the group of “good responders” included GBM cultures which were characterized by considerable induction of dormancy- and stemness-associated genes (exemplified by H2BK and KLF4 in Figures 6A and 7A) in a time-dependent manner in the surviving cells (Figure 6A: LN229, U251MG; Figure 7A: 116/14, 118/14, 124/15). The gene discussed is KLF4; the disease is glioblastoma.
