Abstract:
<b>Introduction:</b> In various pathological conditions, including cancer, transforming growth factor-beta (TGF-β) emerges as a pivotal cytokine.<b>Aim:</b> This study sought to evaluate TGF-β concentrations in blood serum samples and explore potential associations between pre- and post-surgery TGF-β levels in patients with differentiated thyroid cancer and forms of nodular goiter.<b>Material and methods:</b> A total of 70 patients were included, aged 26 to 79, undergoing thyroidectomy for: differentiated thyroid cancer (11), neutral nodular goiter (46), and hyperactive nodular goiter (13). Serum TGF-β1 values were assessed using the Bio-Plex Pro™ Human Cytokine Assay from Bio-Rad Laboratories, and data were analyzed with Bio-Plex Manager™ software.<b>Conclusions:</b> This investigation aimed to provide insights into the dynamics of TGF-β concentrations in the context of thyroid pathologies, utilizing a comparative approach before and after surgical intervention.

Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
The Thyroid Gland
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
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...
Functions of Thyroid Hormones
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...
