The effect of Q‐PAC on the demethylase activity of LSD1 was assessed in vitro using the fluorometric LSD1 Assay Kit (# 700120; Cayman Chemical, Ann Arbor, MI, USA) according to the manufacturer's instructions. Each concentration was assessed in duplicate alongside no inhibitor controls and enzyme‐only reactions, with the average fluorescence intensity from three consecutive measurements used (FLUOstar Optima; BMG Labtech (Mornington, Vic., Australia), excitation/emission 540 nm/580 nm).
