Abstract: The present invention provides a method of testing a sample derived from the blood of a test subject for determining the pathology of rheumatoid arthritis, including the steps of (a) measuring an expression level of at least one miRNA selected from the group consisting of miR-24, miR-26a, miR-28-5p, miR-28-3p, miR-30c, miR-30e-3p, miR-125a-5p, miR-126-3p and miR-502-5p, or expression levels of miR-24, miR-30a-5p and miR-125a-5p, in a sample derived from the blood of a test subject, and (b) correlating the expression level measured in step (a) with the pathology of rheumatoid arthritis.

Abstract: The present invention relates to uses of sarcopodin as a gene associated with distant metastasis or prognosis for survival in tumors. Specifically, the present invention provides a method of determining the risk of distant metastasis or prognosis for survival in a tumor, comprising measuring the expression level of sarcopodin in a tumor tissue. Furthermore, the present invention provides an agent for inhibiting metastasis containing a polynucleotide complementary to an mRNA that encodes sarcopodin or an expression vector capable of expressing the polynucleotide.
