With the aim of verifying the fundamental possibility of using the DLX5 transcriptionfactor as a target for anti-tumor agents and designing drugs that can suppress thedevelopment of certain types of human tumors (T-lymphomas, lung and ovarian cancer),a search for specific ligands of the DLX5 factor was performed based on the analysisof its crystal structure. The gene discussed is DLX5; the disease is lymphoma.
