  • Publication number: 20180080939
    Abstract: The present invention provides a novel cancer marker for testing a morbidity risk of a cancer. The cancer marker according to the present invention is a prorenin receptor. A test method for testing a morbidity risk of a cancer according to the present invention includes measuring a prorenin receptor expression in a biological specimen obtained from a subject and further includes, for example, a step of comparing a prorenin receptor expression level in the biological specimen obtained from the subject with a reference value to test the morbidity risk of the cancer in the subject. The reference value is a prorenin receptor expression level in a biological specimen obtained from a healthy subject or a cancer patient. When the expression level in the subject is higher than that in the healthy subject or identical to or higher than that in the cancer patient, it can be evaluated that the subject has the mobility risk of the cancer.
