Immunogens

Immunogen:

A synthesized peptide derived from human GPX1, corresponding to a region within the internal amino acids.

Uniprot:

P07203(GPX1_HUMAN) >>Visit HPA database.

Gene(ID):
GPX1(2876)
Description:
Glutathione peroxidase 1 (GPX1) is a cytosolic selenoprotein which reduces hydrogen peroxide to water (1). GPX1 is the most abundant and ubiquitous among the five GPX isoforms identified so far (2). It is an important component in the anti-oxidative defense in cells and is associated with a variety of disease conditions, such as colon cancer (3), coronary artery disease (4) and insulin resistance (1).

Compared with the BCNC group, the NAC therapy group significantly decreased the expression and activity of LOX (P <0.05). GPX1 had an upward trend after NAC treatment, but there was no statistical difference (P = 0.0902). The over-expression of MDA was significantly reduced (P <0.05), while the expression of GSH was increased (P <0.05). *P <0.05.
