  • Bone and/or joint disease-associated genes
    Publication number: 20070028314
    Abstract: This invention provides a method for obtaining a gene involved in regulation of cartilage differentiation, in which a transcription factor, preferably Runx2/Cbfa1, is forcedly expressed in a cell that is deficient such transcription factor, preferably in a Runx2/Cbfa1-deficient chondrocyte, and the gene, the expression of which is thereby induced, is selected using DNA chip analysis, subtraction, or other means as well as a Runx2/Cbfa1-deficient chondrocyte useful for carrying out such method.
