doi: 10.1016/j.isci.2026.115796
Figure Lengend Snippet: Multi-pathway dysregulation drives dLAN-induced cardiac injury (A) Heatmap of RNA-seq analysis comparing dLAN-exposed and control zebrafish embryos ( n = 5 zebrafish embryos/group). (B) DCFH-DA staining showing elevated reactive oxygen species (ROS) in dLAN-exposed hearts (dashed outline: cardiac region). Scale bars, 500 μm. (C and D) ELISA quantification of serum heart failure biomarkers, including haptoglobin (HP) (C) and B-type natriuretic peptide (BNP)(D), both significantly increased in dLAN-exposed embryos ( n = 3–4 pools of 50 zebrafish embryos/group). (E) Immunofluorescence staining for activated caspase-3 (red) and DAPI (blue) confirming enhanced apoptosis in dLAN-exposed hearts. Scale bars, 500 μm. (F) Confocal images of Tg (myl7:EGFP;lyz: D sRed) hearts showing neutrophil infiltration (red) into the pericardial space (green myocardium) in dLAN-exposed embryos. Scale bars, 250 μm. (C and D) Data are presented as mean ± SEM. Statistical significance was determined by unpaired two-tailed Student’s t test.
