Figure Lengend Snippet: FIGURE 7 IATL directly binds to STAT3 in melanoma cells. (a) Molecular docking of IATL (PubChem CID: 73285), and STAT3 (PDB ID: 6NUQ) was performed using Autodock Vina 1.2. Three- dimensional binding mode of IATL (green) in complex with STAT3. (b) Two-dimensional binding mode of IATL in complex with STAT3. (c) Molecular dynamics (MD) simulation of surface crystal structure of STAT3-IATL complex at 0 ns (left panels) and 100 ns (right panels). (d) RMSD of all atoms of the STAT3 (green) and IATL (pink). (e) The SPR titration curve of IATL- STAT3 interaction. (f) CETSA for the binding of IATL to STAT3 protein in melanoma cell lysate. The thermal stability of STAT3 in cell lysates treated with IATL (100 μM) at different temperatures was determined by immunoblotting. Representative CETSA blot (left panel) and band intensity results analyzed using Image J software (right panel) are shown. ##p < 0.01, versus DMSO treatment.
