Primary hyperparathyroidism (PHPT) is one of the common endocrine disorders. The major clinical symptoms involve stones, bones, abdominal groans and psychiatric moans. Increased parathyroid cell proliferation and decreased calcium-mediated control of the PTH secretion are characteristic findings. The most common cause of PHPT is adenoma followed by hyperplasia and carcinoma.The molecular mechanisms involved in parathyroid tumorigenesis are partially known. Few genes have been identified and their roles are under study. The genes which are under study by different groups are unable to give a definite direction towards the understanding of parathyroid tumorigenesis and the mechanism involved in overgrowth of parathyroid tissue. So identifying different proteins and their regulation pattern from adenomas to carcinomas will be the initial steps towards understanding the proteins involved in tumorigenesis of parathyroid tissues. By using proteomics approach one can generate protein level information. In this study, using a combined approach based on 2 D gel electrophoresis and mass spectrometry (MS), the investigators propose to study a comparative proteomics to examine the changes of protein profiles in parathyroid tumor tissues with normal and hyperplasic parathyroid tissues. This work plan will help us to understand differentially expressed proteins in patients with PHPT. This will help in understanding the disease and identifying better diagnostic and curative measures of the disease. The investigators are also planning to access nuclear morphometry changes in sporadic parathyroid tumors. It will help in establishing cellular and nuclear change pattern variations from normal to parathyroid tumors.
