Abstract

We have examined expression of bone morphogenetic protein 3 (BMP-3) mRNA in normal rat osteoblasts in culture as they undergo differentiation to form bone-like structures, and have found that expression of BMP-3 mRNA in primary fetal rat calvarial (FRC) cells is discontinuous and shows at least four different-sized transcripts. BMP-3 mRNA expression has a distinct temporal pattern during bone cell differentiation of FRC osteoblasts. Previously, we showed that BMP-3 mRNA is expressed in normal and neoplastic rat and human prostate tissues, and in human osteosarcoma cells, as multiple transcripts. To compare the nature of these transcripts in different tissues, three cDNA clones encoding BMP-3 have been isolated by reverse transcription-polymerase chain reaction (RT-PCR) and cDNA library screening from human prostate cancer PC-3 cells, rat prostate adenocarcinoma PA III cells, and primary FRC cells. Analysis of these clones has revealed that the nucleotide sequence of BMP-3 found in human prostate cells is identical to that found in human bone cells. The rat BMP-3 sequences from bone and prostate cells are also identical but show a high degree of variation in the pro- or precursor region compared with human BMP-3. The biological significance of these differences in these two species is unknown.
