Abstract
The calcitonin receptor (CTR) gene in human osteoclasts formed in a human bone marrow cell culture system was examined by reverse transcription-polymerase chain reaction (RT-PCR). The RT-PCR results indicated that the 5′-untranslated region (5′UTR) was different between CTR mRNAs in human osteoclasts and in a mammary tumor cell line, MCF-7 cells. We isolated the 5′UTR of the CTR gene from human osteoclasts, whose sequence had only 28.6% identity with that of other CTR genes reported until now. In a radioligand binding assay, COS-1 cells transfected with the osteoclast CTR gene bound to [ 125I]human CT (hCT). These results provided evidence that the CTR gene cloned from human osteoclasts was expressed functionally and its coding protein was identical to MCF-7 cell CTR.
