Figure Lengend Snippet: Evaluation of ferroptosis characteristics induced by CDDP2@MSPION@GP3/FAPI in MKN45 cells and CAFs. A–B) Fluorescence distribution (A) and quantification of ROS levels (B) in MKN45 cells treated with PBS (I), MSPION (II), CDDP (III), CDDP2@MSPION@GP3 (IV) or CDDP2@MSPION@GP3/FAPI (V) for 24 h, detected by DCFH-DA staining. C–D) Fluorescence distribution (C) and quantification of ROS levels (D) in CAFs from different treatment groups, detected by DCFH-DA staining. E–G) GPX4 expression in MKN45 cells and CAFs from different treatment groups as determined by Western blot (E), with corresponding statistical analysis (F–G). H–J) CLSM images (H) and corresponding flow cytometry analysis (I–J) of MKN45 cells from different treatment groups, stained with JC-1 to assess mitochondrial membrane potential. Red fluorescence indicates JC-1 aggregates in healthy mitochondria, while green fluorescence represents JC-1 monomers in depolarized (damaged) mitochondria. K–M) CLSM images (K) and corresponding flow cytometry analysis (L–M) of JC-1 stained CAFs from different treatment groups. N-P) CLSM images (N), flow cytometry fluorescence distributions (O), and the quantitative analysis (P) of MKN45 cells after treatments of groups I–V and staining with DAPI and C11-BODIPY. Red fluorescence: reduced form for the decreased LPO. Green fluorescence: oxidized form for the increased LPO. Q–S) CLSM images (Q), flow cytometry fluorescence distributions (R), and the quantitative analysis (S) of CAFs after treatments of groups I–V and staining with DAPI and C11-BODIPY 581/591. Scale bar: 100 μm ∗ P < 0.05. ∗∗ P < 0.01. ∗∗∗ P < 0.001. ∗∗∗∗ P < 0.0001.
