Abstract:
S100 A7 is a small calcium-binding protein that has an important role to play in the differentiation of human kerati -nocytes.It also helps build the chemical defense system of the skin and responds to oxidative stress and inflammation .The expression of S100 A7 can be induced by physical , chemical and biological stimulations .S100 A7 has many ligands and is related to the reactive oxygen species (ROS) via specific signaling pathways.As an important antimicrobial peptide, S100A7 helps the skin fight against main pathogens .S100 A7 is also a key indicator for the state of inflammation and cell differentiation;and its up-regulation has been cor-roborated in various skin diseases .In the brain of patients with Alzheimer′s disease, the up-regulation of S100A7 in primary cortico-hippocampal neurons can inhibit the generation of β-amyloid peptides .Moreover , S100 A7 is also up-regulated in different types of cancer and closely related to tumor malignancy and progression .In this review, we introduce biological properties of S 100A7 and high-light its expression characteristic in related diseases .This should have implication for the discovery of potential biomarkers and targets for the treatment of S100A7-related diseases.
