PubMed Abstract:
Lysine-specific demethylase 1 (LSD1/KDM1A) is a pivotal epigenetic enzyme that contributes to several malignancies including malignant glioma. LSD1 is a flavin adenine dinucleotide dependent histone demethylase that specifically targets histone H3 lysine (K) 4 mono- (me1) and di-methylation (me2) and H3K9me1/2 for demethylation. Herein we report the development of an LSD inhibitor, S2172, which efficiently penetrates the blood-brain barrier. S2172 effectively suppresses LSD1 enzymatic activity, resulting in the depletion of cell growth both in vitro in glioma stem cells (GSCs) (mean half-maximal inhibitory concentration (IC ₅₀) of 13.8 μM) and in vivo in a GSC orthotopic xenograft mouse model. Treatment with S2172 robustly reduced the expression of the stemness-related genes MYC and Nestin in GSC cells. Consistent with this, chromatin immunoprecipitation-sequencing revealed a significant S2172-dependent alteration in H3K4me2/H3K4me3 status. Furthermore, we identified 284 newly acquired H3K4me2 peak regions after S2172 treatment, which were encompassed within super-enhancer regions. The altered H3K4me2/H3K4me3 status induced by S2172 treatment affected the expression of genes related to tumorigenesis. Our data suggest that targeting LSD1 with S2172 could provide a promising treatment option for glioblastomas, particularly due to targeting of GSC populations.
