The present invention relates to compositions and methods for inhibiting DHHC3 palmitoyltransferase for treating cancer. Described herein, are methods of inhibiting expression or activity of programmed death-ligand 1 (PD-L1) in a cell of a subject, e.g., a human subject, in need thereof are carried out by administering to the subject an effective amount of a palmitoyltransferase inhibitor, thereby inhibiting the expression or activity of PD-L1 in the subject. The palmitoyltransferase comprises an Asp-His-His-Cys motif (DHHC)-type protein. Exemplary DHHC-type proteins include DHHC3, DHHC5, DHHC7, and DHHC17.
