Effect of sodin 5 and saporin-S6 on cell viability in HT29 and Caco-2 cells. HT29 ( a ) and Caco-2 ( b ) cell viabilities were evaluated at 24, 48 and 72 h after exposure to the indicated concentrations of sodin 5 (red lines) and saporin-S6 (blue lines). Cell viability was measured using a colorimetric assay based on MTS reduction. The mean results ± S.D. are reported, representing the percentage of control values. Data were analyzed by ANOVA/Bonferroni test, followed by a comparison with Dunnett’s test (confidence range 95%; ** p < 0.01, *** p < 0.001, **** p < 0.0001, versus untreated controls). Asterisks indicate the first concentration at which a statistically significant reduction in cell viability is observed compared to controls. The morphology of HT29 ( c ) and Caco-2 ( d ) cells was evaluated at the indicated times for control (Ctrl) and for treated cells (sodin 5 or saporin-S6 at 10 −6 M concentration). Images were taken using phase-contrast microscopy (total magnification 100×).

Time-dependent TEER changes across Caco-2 monoculture, Caco-2/HT29 and Caco-2/3T3/collagen co-culture models. Caco-2 monoculture ( a ), Caco-2/HT29 ( b ) and Caco-2/3T3/collagen ( c ) co-culture models were established by seeding cells (6.25 × 10 4 Caco-2 cells/cm 2 for monoculture experiments, 6.25 × 10 4 Caco-2/HT29 cells/cm 2 , in a 9:1 ratio, for co-culture experiments) on 24-well Transwell inserts with 0.4 µm transparent polyester membrane. In the Caco-2/3T3/collagen co-culture model, 3T3 cells (0.78 × 10 4 cells/cm 2 ) were seeded on the apical compartment with 0.1 µg/mL of type 1 collagen in complete medium. After 1 h at 37 °C, Caco-2 cells (6.25 × 10 4 /cm 2 ) were seeded. In all experiments, complete medium (900 µL) was added to the basolateral compartment. All cultures were maintained about 10 days, replacing culture medium every 2–3 days. When TEER reached values ≥ 500 Ω × cm 2 (about 10 days), cell monolayers were treated with sodin 5 or saporin-S6 at 10 −6 M concentration. TEER values were recorded at 0, 8, 24, 32, 48 and 72 h after sodin 5 or saporin-S6 intoxication. Results are expressed as mean ± SD of three independent experiments, each conducted in triplicate. Data were analyzed by ANOVA/Bonferroni test, followed by a comparison with Dunnett’s test (confidence range 95%; ** p < 0.01, *** p < 0.001 versus untreated controls). Asterisks indicate the first timepoint at which a statistically significant reduction in TEER is observed compared to controls.

Evaluation of cell death mechanisms triggered by sodin 5 and saporin-S6. HT29 ( a ) and Caco-2 ( b ) cells (4 × 10 5 /well) were seeded in 6-well plates and cultured for 24 h in the absence or presence of sodin 5 or saporin-S6 at 10 −6 M concentration. Apoptosis, necroptosis and necrosis were evaluated through flow cytometry analysis. Representative plots of Annexin V-EGFP (FITC channel)/PI (PE channel) staining of HT29 and Caco-2 cells are shown. Cell populations were characterized based on staining: necrotic cells (PI-positive and EGFP-negative) are in the upper left quadrant; late apoptotic and/or necroptotic cells (PI-positive and EGFP-positive) are in the upper right quadrant; early apoptotic cells (PI-negative and EGFP-positive) are in the lower right quadrant. The plots are representative of two independent experiments, each conducted in triplicate. The tables report the percentages of live, early apoptotic, late apoptotic and/or necroptotic and necrotic HT29 ( c ) and Caco-2 ( d ) cells after sodin 5 or saporin-S6 treatment. The protective effect of cell death inhibitors was evaluated on HT29 ( e ) and Caco-2 ( f ) cells (3 × 10 3 /well), treated with 10 −6 M sodin 5 or saporin-S6. The inhibitors Z-VAD (apoptosis) or necrostatin-1 (NEC, necroptosis) were added at 100 μM concentration 3 h before the RIP treatment. Cells were then treated for 2 h with sodin 5 or saporin-S6 and further incubated for 24 h in complete medium. Cell viability was evaluated using a colorimetric assay based on MTS reduction. The results are expressed as means ± S.D. of three independent experiments, each conducted in triplicate. Data were analyzed by the Mann–Whitney U test (confidence range 95%; ** p < 0.01, *** p < 0.001 versus RIP-treated samples).

PLSCR3 deficiency activates mtDNA‐associated cGAS‐STING signaling. (A) 2 ′ ‐3 ′ ‐cGAMP quantification by ELISA in PLSCR3 knockdown (KD_PLSCR3) HT29 cells and normal controls (NCs) treated with Scramble or dideoxycytidine (DDC) ( p < 0.0001; ns = not significant; n = 3). (B, C) KD_PLSCR3 cells exhibited an elevation in IFN β and CXCL10 production measured by ELISA compared to NC ( p < 0.0001, n = 3). CRISPR‐mediated STING knockout (STING sg) completely abrogated these effects. (D) Western blot analysis showed upregulation of phosphorylated STING and innate immune effectors (IFIH1, ISG60, and ISG15 protein) in STING‐competent KD_PLSCR3 cells relative to GAPDH loading controls. (E) Normalized mRNA level quantification by qPCR demonstrated significant induction of interferon‐stimulated genes (ISGs) in STING‐competent KD_PLSCR3 cells compared with the other groups. Data in panels A–C and E are presented as mean ± SD. Statistical significance was determined using one‐way ANOVA followed by Tukey′s multiple‐comparisons post hoc test for multiple‐group comparisons.
