Introduction: Glycoprotein gp91-phox is an essential component of the NADPH oxidase. The superoxide-generating NADPH oxidase is present in phagocytes, neuroepithelial bodies, vascular smooth muscle cells and endothelial cells. It includes a membrane-bound flavocytochrome containing two subunits, gp91-phox and p22-phox. gp91-phox is a significant element of the membrane-bound oxidase of phagocytes that generates superoxide. It is the terminal component of a respiratory chain th...

Introduction: Thyroid goiter may be present in different thyroid pathologies, such as non-toxic nodular goiter (NTNG) or Hashimoto’s thyroiditis (HT), as a result of focal hyperplasia of thyrocytes (nodal goiter) or generalized enlargement of thyroid (diffuse goiter). Previous studies have demonstrated that programmed cell death, known as apoptosis, plays an important role in the pathogenesis of many thyroid diseases, especially inflammatory conditions.<p class="abste...

Introduction: Catalase is an enzyme, which functions in the detoxification of hydrogen peroxide, and is one of the most important antioxidant enzymes in humans. It is responsible for protecting the cell from oxidative damage by reactive oxygen species. Catalase promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells, and normal and transformed fibroblast cells. Nevertheless, the role of this enzyme in thyroid pathologies i...
