Summary
Survivin (BIRC5) gene expression, particularly the survivin delta Ex3 splice variant, is significantly higher in thyroid cancer tissues compared to benign nodules. This suggests survivin is a key marker for thyroid malignancy.
Area of Science:
- Endocrinology
- Oncology
- Molecular Biology
Background:
- Thyroid cancer incidence has risen, making it the most common endocrine malignancy.
- Identifying prognostic factors is crucial for understanding thyroid cancer progression.
Purpose of the Study:
- To assess survivin (BIRC5) expression and its splice variants (survivin delta Ex3, survivin 2B) in benign and malignant thyroid nodules.
- To determine if survivin expression correlates with thyroid cancer prognosis.
Main Methods:
- Quantitative RT-PCR was used to analyze survivin gene expression and splice variants.
- Thyroid tissue samples from 50 patients (29 with thyroid cancer, 21 with benign/healthy tissues) were analyzed.
Main Results:
- Survivin (BIRC5) expression was significantly elevated in malignant thyroid nodules versus benign and healthy samples.
- Higher BIRC5 transcript levels were observed in advanced tumor stages (pT3/pT4).
- The survivin delta Ex3 splice variant was highly expressed in thyroid carcinomas.
Conclusions:
- Elevated survivin expression, especially the survivin delta Ex3 variant, is a characteristic feature of thyroid malignancy.
- Survivin may serve as a potential biomarker for thyroid cancer diagnosis and prognosis.

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH...

01:25Hyperthyroidism I: Introduction
28
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

01:24Graves Disease II: Pathophysiology
20
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor,...

01:20Synthesis and Regulation of Thyroid Hormones
7.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

01:28Graves' Disease I: Introduction
19
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence...

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
