The 67-kD elastin-laminin receptor (ELR) subunit which carries the recognition site for elastin peptides (EP) is a lectin. Its binding with galactosides can modulate the kinetics of its interaction with its ligand, EP. In this study the biosynthesis of proteins, collagen and fibronectin were evaluated in the presence of agonists and antagonists of the receptor on human skin fibroblasts. The bio...
Retinoic acid is essential for skin growth and differentiation, and its concentration in skin is controlled tightly. In humans, four different members of the short-chain dehydrogenase/reductase (SDR) superfamily of proteins were proposed to catalyze the rate-limiting step in the biosynthesis of retinoic acid (the oxidation of retinol to retinaldehyde). Epidermis contains at least three of these...
Citrinin is a mycotoxin, which is produced by fungi belonging to the genus Monascus, known in biotechnology as producers of azaphilone pigments. The relation between biosynthesis of these secondary metabolites was investigated in different species of the genus Monascus in batch-culture at the following cultivation conditions: T = 28 degrees C, agitation 220 rpm, and a medium, which induce citri...
effect of extracellular calcium depletion on atrial natriuretic factor secretion and gene expression
extracellular ca 2+ concentration ([ca2+]o) may be one of the factors affecting atrial natriuretic factor (anf) release. in the previous studies, there are opposite reports about the effect of [ca2+]o on anf secretion. therefore, the effect of [ca2+]o depletion on anf secretion and gene expression was studied in the present research. isolated right atria from rats were perfused for 6 and 2 hour...
