Summary of "Z-Ligustilide protects vascular endothelial cells from oxidative stress and rescues high fat diet-induced atherosclerosis by activating multiple NRF2 downstream genes."

Oxidative stress-induced endothelial dysfunction is considered to exert a vital role in the development of atherosclerotic coronary heart disease (CHD). NRF2 is a key transcriptional factor against oxidative stress through activation of multiple ARE-mediated genes. Z-Lig is derived from the Ligusticum species with antitumor, anti-inflammation and neuroprotection activities. However, the antioxidant potentials of Z-Lig on endothelial dysfunction and atherosclerosis have not been well elucidated. Therefore, in the present work, we appraise the cytoprotective property and anti-atherosclerosis effect of Z-Lig.

Medical and Biotech [MESH] Definitions

A direct-acting oxidative stress-inducing agent used to examine the effects of oxidant stress on Ca(2+)-dependent signal transduction in vascular endothelial cells. It is also used as a catalyst in polymerization reactions and to introduce peroxy groups into organic molecules.

A protein deglycase that repairs methylglyoxal- and glyoxal-glycated amino acids and proteins, releasing repaired proteins and lactate or glycolate. It deglycates CYSTEINE, ARGININE and LYSINE residues to reactivate proteins by reversing glycation and prevent the formation of ADVANCED GLYCATION END PRODUCTS. It protects cells against OXIDATIVE STRESS and CELL DEATH by functioning as an oxidative stress sensor and redox-sensitive MOLECULAR CHAPERONE and PROTEASE. Mutations in the PARK7 gene are associated with autosomal-recessive, early-onset PARKINSON DISEASE.

A 200-230-kDa tyrosine kinase receptor for vascular endothelial growth factors found primarily in endothelial and hematopoietic cells and their precursors. VEGFR-2 is important for vascular and hematopoietic development, and mediates almost all endothelial cell responses to VEGF.

The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.

A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. Indicators of oxidative stress include damaged DNA bases, protein oxidation products, and lipid peroxidation products (Sies, Oxidative Stress, 1991, pxv-xvi).
