Human parathyroid hormone-related protein (PTHrP) mRNA was detected in peripheral leukemic cells obtained from adult T-cell leukemia (ATL) patients as well as in cultured human T-cell leukemia virus type I (HTLV-I)-infected T-cell lines. In contrast, PTHrP mRNA was not detected in other types of leukemic cells. Using radioimmunoassay, immunoreactive PTHrP was also detected in the spent media of HTLV-I-infected T-cell lines. These results suggest that PTHrP plays an important role in developing the hypercalcemia frequently observed in ATL patients.
在从成人T细胞白血病(ATL)患者获取的外周白血病细胞以及培养的人I型T细胞白血病病毒(HTLV-I)感染的T细胞系中检测到了人甲状旁腺激素相关蛋白(PTHrP)mRNA。相比之下,在其他类型的白血病细胞中未检测到PTHrP mRNA。使用放射免疫测定法,在HTLV-I感染的T细胞系的培养液中也检测到了免疫反应性PTHrP。这些结果表明,PTHrP在ATL患者中常见的高钙血症的发生中起重要作用。
