ABSTRACT
Aim To investigate the effect of m6A demethylase FTO inhibitor(FB23-2)on human glioblastoma stem cell activity. Methods The effects of FB23-2 and Temozolomide on GSC were detected by CCK-8 assay and neurosphere formation assay. The effect of FB23-2 on self-renewal of GSC was detected by limited dilution assay in vitro. The effect of FB23-2 on the proliferation of GSC was detected by EdU method. The effect of FB23-2 on apoptosis of glioblastoma stem cells was detected by flow cytometry. Results CCK-8 assay showed that FB23-2 could effectively inhibit the cell viability of GSC with IC50 values of 7.11 μmol·L-1 and 4.63 μmol·L-1,respectively. The size and number of GSC neural sphere in FB23-2 treatment group were significantly reduced compared with control group. In vitro limited dilution experiment showed that FB23-2 effectively inhibited the self-renewal ability of GSC. EdU incorporation experiment showed that compared with the control group,the treatment group decreased to(70.59±13.74)% and(50.33±4.53)%,respectively. The apoptotic rates of the treated group were(12.16±1.90)% and(16.77±1.17)% by flow cytometry. Conclusions FTO inhibitor FB23-2 can effectively inhibit GSC growth,self-renewal and the formation of neural sphere. In addition,FB23-2 can inhibit the proliferation of GSC and induce its apoptosis.
