Summary
Galectin-8 (gal-8) is highly expressed in papillary thyroid carcinoma, suggesting its potential as a diagnostic marker. However, gal-8 is not useful for differentiating follicular carcinoma from adenoma.
Area of Science:
- Endocrinology
- Oncology
- Pathology
Background:
- Galectin-8 (gal-8) expression is altered in neoplastic cell transformations.
- Thyroid cancer diagnosis and characterization are critical in clinical practice.
Purpose of the Study:
- To investigate galectin-8 expression in normal and pathological human thyroid tissues.
- To evaluate galectin-8 as a potential biomarker for thyroid neoplasms.
Main Methods:
- Immunohistochemistry was used to analyze galectin-8 expression.
- 41 archival thyroid tissue samples (papillary carcinomas, follicular carcinomas, adenomas) and 36 adjacent normal/hyperplastic tissues were studied.
Main Results:
- Galectin-8 was detected in 87% of papillary thyroid carcinomas.
- Weaker galectin-8 staining was observed in 40% of follicular carcinomas and 40% of adenomas.
- Galectin-8 was undetectable in normal thyroid tissue and weakly positive in 29% of adjacent hyperplastic areas.
Conclusions:
- High galectin-8 expression in papillary thyroid carcinoma suggests its potential as a diagnostic marker.
- Galectin-8 is not helpful in differentiating follicular carcinoma from adenoma.
- Further research is needed to elucidate the biological functions of galectin-8 in thyroid lesions.

The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Synthesis and Regulation of Thyroid Hormones
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 iodine is then...

Graves' Disease I: Introduction
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 in...
Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
Graves Disease II: Pathophysiology
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, and heat...
