LH inhibits OSCC cell proliferation in vitro. (A) Chemical structure of LH. (B) HSC-3, HSC-4, UM1 and UM2 OSCC cell lines were incubated with LH at the indicated concentrations for 24 h, and cell proliferation was measured using a CCK-8 assay. (C) HSC-3 cells were incubated with LH at the indicated concentrations for 24 and 48 h, and cell proliferation was measured using a CCK-8 assay. IC50 value of LH-treated OSCC cells was calculated with GraphPad Prism 7 software. OSCC, oral squamous cell carcinoma; LH, lycorine hydrochloride; CCK-8, Cell Counting kit-8.
