Figure Lengend Snippet: LHA induces pyroptosis through targeting eEF2K in PDAC cells. (A) Molecular docking of LHA on eEF2K protein. Predicted two-dimensional and three-dimensional crystal structures of LHA (PubChem CID: 5318998) and the eEF2K (PDB ID: 7SHQ) complex. (B) MIA PaCa-2 and BxPc3 cell lines were treated with LHA (0, 7.5, 10, and 12.5 μM) for 48 h. The expressions of eEF2K, p-eEF2, and eEF2 were examined using Western blotting. Data were expressed as mean ± S.D. of at least three independent experiments. *p < 0.05, **p < 0.01, and ***p < 0.001 vs. control. (C) MIA PaCa-2 and BxPc3 cell lines were transfected using lentivirus vectors with the overexpressed human eEF2K gene, and the images were captured using the fluorescent microscope after 72 h of transfection. (D) MIA PaCa-2 and BxPc3 with or without eEF2K overexpression. The expressions of eEF2K were examined using Western blotting. Data were expressed as mean ± S.D. of at least three independent experiments. **p < 0.01 vs. control. (E) The cell viability of MIA PaCa-2 and BxPc3 cell lines with or without overexpression of eEF2K was examined using MTT assay. Data were expressed as mean ± S.D. of at least three independent experiments. *p < 0.05, **p < 0.01, and ***p < 0.001 vs. control. # p < 0.05, ## p < 0.01, and ### p < 0.001 vs. overexpression eEF2K with the same LHA concentration. (F) MIA PaCa-2 and BxPc3 with or without eEF2K overexpression with LHA (0 and 12.5 μM) for 48 h. The expressions of eEF2K, GSDMD-N, GSDME-N, and IL-1β were examined using Western blotting. Data were expressed as mean ± S.D. of at least three independent experiments. *p < 0.05, **p < 0.01, and ***p < 0.001 vs. control. ## p < 0.01 and ### p < 0.001 vs. overexpression eEF2K with the same LHA concentration.
Article Snippet: Lentivirus vectors carrying the overexpressed human eEF2K gene and green fluorescent protein (GFP) were designed and produced as “LV-EEF2K (100354-1).” The construct was bought from the Genchem Company (Shanghai, China).
