USE OF ADCY3 FOR DIAGNOSIS AND TREATMENT OF GASTRIC CANCER

摘要

The present invention relates to: a composition for detecting a gastric cancer marker comprising a preparation for measuring the expression level or methylation level of mRNA of ADCY3 or a protein thereof; a kit for diagnosing gastric cancer, containing the composition; a method for diagnosing gastric cancer by treating a biological sample with the preparation to ascertain whether a material for complementarily binding to the preparation exists and comparing the amount thereof with a control group; a composition for treating and preventing gastric cancer, containing a preparation capable of inhibiting ADCY3 polynucleotide or ADCY3 polypeptide; and a method for treating gastric cancer by administering the composition to an individual. According to the present invention, it is possible to diagnose gastric cancer with high diagnostic sensitivity and specificity using ADCY3 as a marker for diagnosing gastric cancer, and thus the present invention can greatly contribute to reducing mortality due to gastric cancer. In addition, the preparation capable of controlling the expression of ADCY3 of the present invention can be used in the prevention and treatment of gastric cancer.
