Figure Lengend Snippet: Mixed infection with S.m. and F.n. induced PANoptosis in DPCs (A–H) Dental pulp cells were infected with S.m. (MOI = 100), F.n. (MOI = 100), or a combination of S.m. (MOI = 100) and F.n. (MOI = 100) or treated with PBS (negative control, NC) for 8 h. (A) Dental pulp cells were treated with PBS, S.m. , F.n. , or a combination of S.m. and F.n. ( n = 5 experiments in each group), and cell death was quantified by measuring LDH release. (B) Dental pulp cells were treated with PBS, S.m. , F.n. , or a combination of S.m. and F.n . Treated DPCs were stained with PI, fixed, counterstained with DAPI, and visualized under a microscope. Scale bars, 100 μm. (C) Quantification of the proportions of PI-positive cells in B ( n = 6 experiments in each group). (D) Dental pulp cells were treated as indicated and analyzed by flow cytometry. (E) PANoptotic DPCs were quantified by determining the percentages of PI + /annexin V + cells ( n = 3 experiments in each group). (F) The protein levels of cleaved caspase-3 p17, cleaved GSDMD NT, and p -MLKL were assessed by Western blot. (G) Immunofluorescence staining of PANoptotic markers in infected DPCs, as visualized using a confocal microscope. Scale bars, 10 μm. (H) Quantification of PANoptotic cell proportions in DPCs treated with PBS, S.m. , F.n. , or a combination of S.m. and F.n. ( n = 8 samples in each group), corresponding to (G). Data are represented as mean ± SEM. ∗∗ p < 0.01, ∗∗∗ p < 0.001, and ∗∗∗∗ p < 0.0001 by one-way ANOVA (A, C, and E) or by Kruskal-Wallis test (H).

Article Title: FOXE1 promotes the progression of pulp inflammation by activating PANoptosis in dental pulp cells

doi: 10.1016/j.isci.2026.115204

Figure Lengend Snippet: Identification and validation of FOXE1 as a key transcription factor that regulates PANoptosis in DPCs (A) Differentially expressed gene analysis was performed between the PANoptotic DPC cluster (cluster 1) and other DPC clusters (clusters 0, 2, 4, 5, and 6) and between cluster 1 and all remaining clusters. The candidate regulators were selected from the overlapping DEGs between these comparisons. (B) The top five candidate regulators were identified after comparison. (C) siRNA targeting FOXE1 (20 μM) was transfected into DPCs with Lipofectamine 2000 for 24 h. The knockdown efficiency was validated by qRT-PCR ( n = 3 experiments in each group) and Western blot. (D–H) Dental pulp cells were pretreated with siRNAs (20 μM) targeting candidate regulators for 24 h, followed by infection with S.m. (MOI = 100) and F.n. (MOI = 100) for 8 h. (D) Cell death was quantified by the LDH release assays ( n = 5 experiments in each group). (E, also see in ) Cell death was assessed by PI staining ( n = 4 experiments in each group). (F) Treated cells were analyzed by flow cytometry. (G) PANoptotic DPCs were quantified by determining the percentages of PI + /annexin V + cells ( n = 3 experiments in each group). (H) Western blot analysis was used to assess the expression of cleaved caspase-3 p17, cleaved GSDMD NT and p -MLKL. (I) Immunofluorescence staining of PANoptotic markers in si FOXE1 -and siCON-transfected DPCs. Scale bars, 10 μm. (J) Quantification of PANoptotic DPCs in I ( n = 5 samples in each group). Data are represented as mean ± SEM. ∗∗ p < 0.01, ∗∗∗ p < 0.001, and ∗∗∗∗ p < 0.0001 by Student’s t test (C, G, and J) or by one-way ANOVA (D and E).
