Article Title: PLSCR3 Deficiency Triggers mtDNA‐Driven cGAS‐STING Activation to Potentiate Antitumor Immunity in Colorectal Cancer

doi: 10.1155/humu/8545428

Figure Lengend Snippet: PLSCR3 deficiency disrupts mitochondrial homeostasis in CRC cells. (A) Western blotting verified the reduction of PLSCR3 protein levels in HT29 cells. (B) RT‐qPCR analysis verified reduction of PLSCR3 mRNA levels normalized to GAPDH compared with negative control (NC) cells ( p < 0.0001, n = 3). (C) Representative JC‐1 staining (scale bar: 20 μ m) images showing red fluorescence (polarized mitochondria) and green fluorescence (depolarized mitochondria). (D) Quantification of the JC‐1 red/green fluorescence intensity ratio. Fluorescence intensity was quantified using ImageJ software as described in the section. (E) Real‐time oxygen consumption rate (OCR) profiles under sequential treatment with oligomycin, FCCP, and rotenone/Antimycin A. (F) Quantification of cytosolic mtDNA by qPCR using the D‐loop ratio in PLSCR3‐knockdown and control cells. Data are presented as mean ± SD from three independent experiments. Statistical significance was determined using an unpaired two‐tailed Student′s t ‐test for two‐group comparisons.

Article Snippet: Cells were incubated with JC‐1 dye (MedChemExpress, Cat. No. HY‐K0601) at 37°C in the dark, enabling accumulation in mitochondria; high membrane potential promoted J‐aggregate formation (red fluorescence), while depolarized mitochondria retained JC‐1 monomers (green fluorescence).

Article Title: PBX3 regulates mast cell parthanatos via TOP2A mediated DNA damage in allergic rhinitis

doi: 10.1016/j.isci.2026.115426

Figure Lengend Snippet: Regulatory role of TOP2A in mast cell apoptosis, parthanatos pathway, and inflammatory response In vitro experimental groups: CON, model, Model+OE-NC, Model+OE-TOP2A, Model+si-NC, Model+si-TOP2A. (A and B) RT-qPCR and western blot analyses were conducted to assess the mRNA and protein expression levels of TOP2A and PARP-1 in mast cells. ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001 vs. the CON or Model+OE-NC or Model+si-NC group. (C) TUNEL staining was performed to evaluate and visualize cell apoptosis. ∗ p < 0.05, ∗∗ p < 0.01 vs. the CON or Model+OE-NC or Model+si-NC group; scale bars, 50 μm. (D) Cell proliferation activity in each group was measured using the CCK-8 assay. ∗∗ p < 0.01 vs. the CON or Model+OE-NC or Model+si-NC group. (E and F) MMP was assessed using the JC-1 assay to evaluate mitochondrial function. ∗∗ p < 0.01, ∗∗∗ p < 0.001 vs. the CON or Model+OE-NC or Model+si-NC group. (G) Western blotting was used to examine the protein levels of mitochondrial AIF (Mito-AIF), cytoplasmic AIF (Cyto-AIF), and nuclear AIF (Nucleo-AIF), along with visual analysis. ∗∗ p < 0.01, ∗∗∗ p < 0.001 vs. the CON or Model+OE-NC or Model+si-NC group. (H and I) ELISA was employed to determine the concentrations of β-hexosaminidase, Histamine, IL-4, IL-5, and IFN-γ. ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001 vs. the CON or Model+OE-NC or Model+si-NC group. Data are represented as mean ± SEM ( n = 3 per group) from independent biological replicates. One-way ANOVA with Tukey’s post hoc correction for (A–D) and (F–I).

Article Snippet: After experimental treatments, cells were stained with JC-1 dye solution (5×, Beyotime) and incubated at 37°C in the dark for 20 min.
