Abstract | OBJECTIVE: METHODS: We examined the coexpression of PTH/PTHrP receptor and ligand in 73 glial tumors of different histological grades and 4 nonneoplastic human brain specimens and three glioblastoma cell lines, by using Western Blot analysis and immunohistochemical analysis. RESULTS:
PTHrP and PTH/ PTHrP receptors were shown in the neurons, reactive astrocytes and the endothelial cells of normal brain tissue as well as tumor cells, reactive astrocytes and vasculature of nonneoplastic tissue. They were expressed at higher levels in pure astrocytic tumors as compared to tumors with oligodendroglial components. CONCLUSION:
