doi: 10.3389/fmed.2025.1554934
Figure Lengend Snippet: Xanthatin induces caspase-dependent apoptosis in a concentration-dependent manner in retinoblastoma cells. (A) Gene expression analysis from the GEO dataset (GSE208143) comparing the retinoblastoma (RB) group to the normal control (NC) group, showed a decrease in caspase-3 expression and an increase in caspase-8 and c-FLIP expression in the RB group. (B) Gene Set Enrichment Analysis (GSEA) from GSE208143, highlighting enrichment of the apoptosis gene set in the RB group, with a normalized enrichment score (NES) of 2.145 and a p -value <0.01. (C,D) Flow cytometry analysis of apoptosis in Y79 (C) and WERI-RB-1 (D) cell lines treated with xanthatin at concentrations of 0, 5, 10, and 20 μM for 48 h. (E) Quantification of apoptosis rates in Y79 and WERI-RB-1 cells treated with xanthatin (0, 5, 10, 20 μM) for 48 h, corresponding to the flow cytometry results in C,D . (F) Western blot analysis showing the expression levels of caspase-8, caspase-9, caspase-3, cleaved caspase-3, and cleaved PARP in Y79 and WERI-RB-1 cells treated with xanthatin (0, 5, 10, 20 μM).
Article Snippet: The Y79 retinoblastoma cell line was obtained from ATCC, and the WERI-RB-1 cell line was obtained from Procell Biotechnology Co., Ltd. (Wuhan, China).
