Hepcidin as a Potential Biomarker for the Diagnosis of Anemia.

There are several blood-based markers to assess iron stores, but they all have some limitations. Hepcidin, a low-molecular-weight peptide hormone, is produced mainly by the liver. It is the main regulator of iron homeostasis by preventing iron release into plasma from absorptive enterocytes and macrophages.

PAD4: pathophysiology, current therapeutics and future perspective in rheumatoid arthritis.

Peptidyl arginine deiminase 4 (PAD4) is an enzyme that plays an important role in gene expression, turning out genetic code into functional products in the body. It is involved in a key post translational modification, which involves the conversion of arginine to citrulline. It regulates various processes such as apoptosis, innate immunity and pluripotency, while its dysregulation has a great impact on the genesis of various diseases.

Effect of curcumin on proliferation of human retinal endothelial cells under in vitro conditions.

Purpose: To investigate the effect of high glucose on the proliferation of human retinal endothelial cells (HRECs) and to elucidate the possible mechanisms of antiangiogenic activity of curcumin, a diferuloylmethane.

Methods: Human retinal endothelial cells were isolated from the retinal tissue obtained from human donors and the culture system was established. The effect of curcumin on the proliferation of primary HRECs in the presence of low and high glucose was measured by MTT and thymidine uptake assays.
