| 摘要 |
The present invention provides a suppressing agent for inflammatory cytokine expression in joints and/or joint destruction (e.g., articular cartilage destruction) and/or pain in a bone/joint disease, comprising a substance that suppresses the expression or activity of a protein comprising the same or substantially the same amino acid sequence as the amino acid sequence shown by SEQ ID NO:2, a screening method for a substance that regulates inflammatory cytokine expression in joints and/or joint destruction (e.g., articular cartilage destruction) and/or pain in a bone/joint disease, comprising using the protein or a partial peptide thereof, and a diagnostic method for genetic susceptibility to a bone/joint disease, comprising detecting a polymorph in the base shown by base number 24007 in the partial base sequence of the human EDG2 gene shown by SEQ ID NO:3.
