Figure Lengend Snippet: A Structures of selected ERX-41 analogs. B Heatmap depicting the antiproliferative effects of selected ERX analogs on OCa cells in vitro. C MTT assay results demonstrating the potency of ERX-208 over ERX-41 on the viability of OCa cells in vitro. D – F MTT assay results showing the impact of ERX-208 on the viability of OCa cells in vitro. G , H , Colony formation assay results illustrating the effect of ERX-208 on the clonogenic potential of OCa cells in vitro. The left panel ( G ) presents representative images of colonies formed, while the right panel ( H ) quantifies the number of colonies in control versus ERX-208-treated cells. I ERX-208 induces caspase-dependent apoptosis in treated ES2 OCa cells. Caspase 3/7 activity (fold change) was measured after treatment with ERX-208 (500 nM) alone or in combination with Q-VD-Oph (caspase inhibitor), ferrostatin-1 (ferroptosis inhibitor), or necrostatin-1 (necroptosis inhibitor). Data are represented as mean ± SEM. ns not significant; *** p < 0.001; **** p < 0.0001.

Figure Lengend Snippet: A Time-course analysis of ERX-208 (1 μM) treatment on mRNA expression of ER stress-related genes, sXBP1 and CHOP, in SKOV3, OVCAR3, ES2, and OVCAR4 cells. B RT-PCR analysis showing the temporal effects of ERX-208 (1 μM) on the expression of XBP1 (unspliced XBP1 (XBP1u) and spliced XBP1 (XBP1s)) in OCa39, OVCAR8, OVCAR3, and ES2 cells. C Western blot analysis of UPR component activation in OCa39 and OVCAR8 OCa cell lines treated with ERX-208 for the indicated time points. D Transmission electron microscopy of OVCAR8 cells illustrating the effects of vehicle and ERX-208 treatments on subcellular structures after 16 h.; yellow arrows indicate the ER. Scale bar represents 100 nm.

Figure Lengend Snippet: Fig. 6 PVRbbz CAR-T cells effectively killed multiple tumor cell lines even at low effector:target ratios and corroborated by cytokines release. A-L Cytotoxicity of PVRbbz CAR-T cells on PC3 (A and G), PANC1 (B and H), U20S (C and I), ES2 (D and J), Huh7 (E and K) and MM.1S (F and L) cells at the indicated effector:target (E:T) ratios after 12 h of co-culturing. Cell Lysis was determined by luciferase and relative IVIS picture was shown. Two independent experiments were performed. M and N The concentrations of TNF-α (M) and IFN-γ (N) in supernatants from cytotoxicity assays at 1:1 effector:target after co-culture with tumor cells for 12 h were measured by ELISA kits. Three independent experiments were performed. Significance was calculated by two-way ANOVA. All error bars represent mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
