Article Title: Cepharanthine inhibits lysosomes and induces apoptosis in triple-negative breast cancer cells
doi: 10.3892/mmr.2026.13899
Figure Lengend Snippet: CEP does not induce LMP, increase lysosomal pH or destabilize lysosomal membrane-bound enzymes in triple-negative breast cancer cells. (A) CEP does not induce LMP, as evidenced by a dispersion of dextran, in MDA-MB-231 (10 µM; 24 h) and Hs578T cells (4 µM; 24 h). Scale bar, 25 µm. (B) CEP does not elevate lysosomal pH in the MDA-MB-231 (10 µM; 24 h) and Hs578T cell lines (4 µM; 24 h). Scale bar, 25 µm. (C) CEP does not induce lysosomal membrane-bound enzymes degradation in the MDA-MB-231 (10 µM; n=3; 24 h) and Hs578T cell lines (4 µM; n=3; 24 h). CEP, cepharanthine; ASAH1, acid ceramidase; SMPD1, sphingomyelin phosphodiesterase; ns, not significant.

CL-0114; Procell Life Science & Technology Co., Ltd.) were cultured in high-glucose DMEM medium (cat. no. C11965500BT; Gibco; Thermo Fisher Scientific, Inc.), supplemented with 10% fetal bovine serum (cat. no. 164210; Procell Life Science & Technology Co., Ltd.) and 1% penicillin/streptomycin (cat. no. 15140122; Gibco; Thermo Fisher Scientific, Inc.).
