Method for diagnosis of bile duct cancer using methionyl-tRNA synthetase in bile duct cell

A method for treating a bile duct cancer in a latent patient, the method comprising the steps of:

• obtaining a sample from a latent patient;
• measuring the expression level of a methionyl-tRNA synthetase (MRS) protein in the sample;
• comparing the measured protein expression level of the latent patient with that of a control;
• diagnosing the patient with a bile duct cancer when the protein expression level of the patient is increased in comparison with that of the control;
• and
• treating the diagnosed patient by conducting at least one of a chemotherapy, a surgery, and a radiation therapy.
