From: Epigenetic drug library screening identified an LSD1 inhibitor to target UTX-deficient cells for differentiation therapy

Fig. 7

A working model of the molecular mechanism by which SP2509 induces the differentiation of Utx-deficient cells. a Schematic showing that the H3K4 methylation activity of MLL3/4 in the COMPASS-like complex is impaired by Utx deficiency, which leads to a reduced expression of differentiation-related genes and tumor suppressors. b Schematic showing that in Utx-deficient cells, the small molecule SP2509 inhibits the demethylation activity of LSD1 on H3K4 and therefore rescues the expression of differentiation-related genes and tumor suppressors
