Article Title: IL-37/IL-1R8 blocks keratinocyte acantholysis via suppressing ADAM17/EGFR

doi: 10.3892/ijmm.2026.5793

Figure Lengend Snippet: IL-37/IL-1R8 protects HaCaT cells from keratinocyte dissociation and apoptosis through the ADAM17/EGFR pathway. (A) Protein expression levels of ADAM17, p-EGFR, total EGFR as well as EGFR downstream protein p-AKT, p-ERK1/2 and p-STAT3 levels were determined by western blotting. HaCaT cells were treated with EGFR activator NSC228155. (B) Cell dissociation was analyzed by cell dissociation assay. (C) Cell apoptosis was analyzed by flow cytometry. (D) Protein expression levels of Bcl-2 and Bax were analyzed by western blotting. (E) HaCaT was transfected with ADAM17 siRNA and the transfection efficiency was detected by western blotting. HaCaT cells were transfected with ADAM17 siRNA or treated with 1 μ M of EGFR inhibitor AG1478 for 30 min followed by treated with AK23. (F) Cell dissociation was analyzed by cell dissociation assay. (G) Cell apoptosis was analyzed by flow cytometry. # P<0.05 vs. Control group; & P<0.05 vs. anti-Dsg3 group; @ P<0.05 vs. anti- Dsg3 + IL-37 + si-NC group; * P<0.05; Data are presented as mean ± SD, n=3 biological indepen- dent replicates. One-way ANOVA with Bonferroni's post-hoc test was used for multiple group comparisons. IL, interleukin; ADAM17, TNF-alpha-converting enzyme; EGFR, epidermal growth factor receptor; p- phosphorylated; STAT, signal transducer and activator of transcription; si, short interfering.

Article Snippet: For EGFR inhibition assay, HaCaT cells were pre-treated with 1 μ M of EGFR inhibitor AG1478 (MedChemExpress) at 37°C for 30 min followed by treatment with AK23 for 24 h at 37°C.

Article Title: MFAP2 promotes metastasis and drug resistance by regulating epithelial-to-mesenchymal transition through EGFR signaling pathway in colorectal cancer cells

doi: 10.1016/j.gendis.2025.101800

Figure Lengend Snippet: MFAP2 promotes epithelial–mesenchymal transition (EMT) through the EGFR-AKT-STAT3 signaling pathway in colorectal cancer (CRC) cells. (A, B) The top 20 enrichment signaling pathways regulated by MFAP2 knockdown. (C, D) VEGFR2 signaling pathway was enriched in the MFAP2 knockdown cells, shown by Gene Set Enrichment Analysis (GSEA) and essential genes in this enrichment. (E) MFAP2 knockdown affected the EGFR-AKT-STAT3 axis.

Article Snippet: Following blocking with 5% non-fat milk in PBS with 0.02% Tween 20 detergent (PBST) at room temperature for 2 h, the membranes were incubated with primary antibodies, including MFAP2 (Solarbio, China), GAPDH (BBI Co., Ltd., China), epidermal growth factor receptor (EGFR; Proteintech, China), protein kinase B (AKT) (Proteintech), signal transducer and activator of transcription 3 (STAT3) (Proteintech), and vascular endothelial growth factor A (VEGFA) (Proteintech), p-EGFR (Cell Signaling Technology, USA), p-STAT3 (Cell Signaling Technology), and p-AKT ser473 (Cell Signaling Technology) antibodies, at 4 °C overnight.
