Introduction: The molecular events involved in the formation of parathyroid adenomas are not well understood. Two genes, cyclin D1 (CCND1) and MEN-1, have been established as having major roles in parathyroid tumorigenesis. Tumor suppressor gene HRPT2 is frequently mutated in parathyroid carcinoma. The aim of our study was to analyze HRPT2 expression in parathyroid adenomas and in residual normal/atrophic parathyroid tissue and to relate it to other...
