Figure Lengend Snippet: 84-EBET shows substantial anticancer efficacy in CRC, LC, and BC models in vitro and in vivo . A, IHC analysis of CRC-1, CRC-5, BRE-704, and H1573 tumors. Scale bar, 100 μm. B, Growth inhibition by ADCs and standard chemotherapies in CRC-1, CRC-5, and BRE-704 PDX-derived organoids and the H1573 cell line. Data are presented as mean ± SD ( n = 4 biological replicates). Fitted curves with nonlinear regression are shown. SN38, an active metabolite of irinotecan. 5FU + OXA has a different concentration range (10 nmol/L to 100 µmol/L + 1 nmol/L to 10 µmol/L) from those of the other agents. C, Relative tumor growth curves in response to ADCs and standard chemotherapies in CRC-1, CRC-5, BRE-704, and H1573 xenograft models. Arrowheads indicate times of drug administration. Data are presented as mean ± SD ( n = 5 mice). CDX, cell line–derived xenograft; HEL, hen-egg lysozyme 3 (control).
