Lycorine inhibits cell proliferation in a dose-dependent manner in the abovementioned 4 PCa cell lines, and the IC 50 ranged from 5 μM to 10 μM., it also shows Lycorine has little effects on PNT1A cell's proliferation.SCAP (SREBF chaperone) is an ER-toGolgi transport protein, undergoes a conformational change, and regulates/preserves SREBFs in the ER by forming a complex with INSIG1 (insulin induced gene 1).Lycorine (5-40 μM; 16 hours) significantly suppresses SREBFs activity (up to -70%) in a dosedependent manner and does not cause obvious cytotoxicity in cells.Lycorine (10-20 μM; 2-16 hours) dose- and time-dependently decreases the mature SREBF1 and SREBF2 proteins in HL-7702 cells.Lycorine (20 μM; 16 hours) neither activates NR1H3 transcription nor affect NR1H3 target genes, including ABCG5 and ABCG8, but Sterols activates NR1H3 transcription activity.Lycorine hydrochloride (0-25 μM; 48 hours) treatment markedly suppresses the expression of vascular endothelial (VE)-cadherin in a dose-dependent manner and also slightly diminishes the expression of Sema4D in C8161 cells. However, the expression of the other six genes is not affected.Lycorine hydrochloride (0-25 μM; 48 hours) treatment markedly reduces VE-cadherin protein levels in C8161 cells in a dose-dependent fashion.
