A method of characterizing the protein O-GlcNAcylation site-specificity of an antibody. A method of detecting or quantitating the expression of site-specific O-GlcNAcylated proteins expressed in cells and biological samples. A method of diagnosing cancer in a host based on the cellular expression of site-specific O-GlcNAcylated proteins. A method of screening anti-cancer compounds according to their ability to increase a level O-GlcNAcylation of oncogene or tumor suppressor proteins. Methods of treating cancer in an animal host by administering compounds that increase a level of O-GlcNAcylated c-myc or p53 in cancer cells. A method of distinguishing subclasses of pancreatic cancer according to the sensitivity of pancreatic cancer cells to an imidazole derivative, and a method of personalized pancreatic cancer treatment delivered according to the sensitivity subclasses.
