It could down-regulate the Wnt/β-catenin signaling in Apc-truncated CRC cells, but had little effects in wild-type cancer cells.350 An SMI from the synthetic chemical library of lycorine derivatives, 4-ethyl-5-methyl-5,6-dihydro-[1,3]dioxolo[4,5-j]phenanthridine (HLY78), activated Wnt/β-catenin signaling by targeting the DIX domain of Axin and enhanced the effect of Axin-Lrp5/6.351. The gene discussed is AXIN1; the disease is colorectal carcinoma.
