To identify genes preferentially expressed at the hypertrophic stage rather than early differentiation stages of chicken chondrocyte differentiation, a subtracted cDNA library was generated. Here we describe the characterization of a cDNA isolated from this library and that of the encoded protein referred to as Chondrocyte Protein with a Poly-proline Region (CHPPR). The cDNA coding for CHPPR hybridizes with a 3.0-kb mRNA expressed at extremely low levels in dedifferentiated chondrocytes, cultured in adherent conditions, at low levels in differentiating chondrocytes and at very high levels in hypertrophic chondrocytes in suspension culture. The Parathyroid Hormone peptide [PTH (1-34)] enhances accumulation of CHPPR mRNA in cultured chondrocytes. This 3.0-kb mRNA is also detectable in several chick embryo tissues but at a lower extent when compared to that present in cartilage and in hypertrophic chondrocytes. The CHPPR cDNA has a complete open reading frame coding for a polypeptide with a calculated mass of 35.6 kDa containing a proline-rich region with a PPLP motif (single-letter amino acid code). We demonstrate by Western blot analysis that two CHPPR isoforms are detected in the cell lysates from cultured chondrocytes when they are not in the culture medium; furthermore, we find that the CHPPR gene is expressed in vivo by chick embryo chondrocytes at higher levels in the prehypertrophic and hypertrophic zones."xsd:string |
