Multiple Endocrine Neoplasia type 1 (MEN1) is an autosomal dominant disorder characterised by the combined occurrence of tumours of the parathyroids, pancreas and pituitary. The MEN1 gene, which is located on chromosome 11q13 and encodes a 610 amino acid protein (menin), belongs to the class of tumour suppressors. To investigate the role of menin in tumour suppression, three different mouse models have been generated through targeted disruption of the Men1 gene. ...

Inbred laboratory mice are widely used to generate, by homologous recombination, transgenic and chemical mutagenesis routes, genetic models of human disease. However, physiological studies of such models are hampered by the lack of normal ranges for serum and urinary biochemistry, particularly in relation to acclimatisation following placement in metabolic cages. To establish such values, we investigated urinary and serum parameters in forty, 24–30 week-old C3H/HeH, BALB/...

Introduction: Graves’ disease (GD) is often treated with radioiodine therapy for cure. While, post external irradiation and post-radioiodine therapy (RAI) induced hyperparathyroidism after many years of latency is a well known phenomenon, there are only anectodal reports of post-radioiodine hypocalcemia. The factors contributing to this are poorly understood. In this context, we evaluated our own series to look deeper in to this issue.Material and m...

Introduction: Primary Hyperparathyroidism (PHPT) is a frequent endocrine disease which requires surgical excision for definitive cure. Apart from genetic role in its pathogenesis, there are conflicting reports about role of immunomodulation in literature. In this context, we set out study the role of Pro- inflammatory cytokines in PHPT in South Indian population.Material and methods: This prospective case-control study was conducted on surgically managed...

Introduction: Tumor necrosis factor alpha (TNF-α) and Interleukin-6 (IL-6) are potent immunomodulators and proinflammatory cytokines displaying varied functions. Apart from monocytes/macrophages, they are also produced by the cells in female reproductive tract. Polycystic ovarian syndrome (PCOS) is one of the commonest endocrine disorder amongst women of reproductive age group. Several polymorphisms in the promoter region of the gene TNF-α, IL-6 and Leptin receptors ...

Introduction: Graves’ disease (GD) is one of the commonest organ specific autoimmune thyroid disease. Surgical thyroidectomy is one of the definitive treatment modalities. Autoimmunity has been implicated as one of the main cause of GD. In this context, we set out study the role of Pro- inflammatory cytokines in GD.Material and methods: This prospective case-control study was conducted on surgically managed GD patients. Institutional ethical committ...

Introduction: Hashimoto’s thyroiditis (HT) is one of the commonest organ specific autoimmune thyroid disease. Though it is mostly treated medically, certain goitrous forms require surgical thyroidectomy for various indications. Autoimmunity has been implicated as one of the main cause of HT. In this context, we set out study the role of Pro- inflammatory cytokines in HT.Material and methods: This prospective case-control study was conducted on surgi...

Introduction: Contrary to the high prevalence of polycystic ovarian syndrome (PCOS) amongst reproductive age group women, there is disproportionate uncertainity over its etiopathogenesis. Substantial evidence suggests immunological-inflammatory role in causing this endocrine disorder. In this context, we set out study the role of inflammatory biomarkers in PCOS.Material and methods: This prospective case-control study was conducted on PCOS patients diagn...

Introduction: Nodular thyroid disease (NTD) is one of the commonest endocrine disease with incidence ranging from 5–30% in various populations Worldwide. They often require surgery for indications such as pressure symptoms or size related reasons. The natural history and etiopathogenesis are largely unclear except in few endemic regions. Immunomodulatory role has often been implicated in their pathogenesis. In this context, we set out study the association between Pro- in...

Introduction: The adenoma – carcinoma sequence in thyroid nodules is a enigmatic phenomenon. There are conflicting reports on development of papillary cancer from benign adenomas. Genomics is the only definitive modality to resolve this hypothesis. Adenomas and papillary carcinomas tend to have mutations in Sodium Iodide symporter gene (NIS) and highly specific BRAF gene respectively. In this context, we set out study the prevalence of these somatic mutations in surgical ...
