PLSCR3 deficiency activates mtDNA‐associated <t>cGAS‐STING</t> signaling. (A) 2 ′ ‐3 ′ ‐cGAMP quantification by ELISA in PLSCR3 knockdown (KD_PLSCR3) HT29 cells and normal controls (NCs) treated with Scramble or <t>dideoxycytidine</t> <t>(DDC)</t> ( 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.

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.
