Hydrogen Peroxide Impact on Cells
On the effect of hydrogen peroxide on cells
The role of hydrogen peroxide in cells is really important for scientific research. It has a significant impact on cell physiology and pathology.
Hydrogen peroxide has strong oxidative properties and is a common reactive oxygen species in cell metabolism. When appropriate, it can act as a messenger for cell signal transduction and participate in the regulation of cell growth, proliferation and differentiation. For example, during an immune response, immune cells can produce hydrogen peroxide to resist the invasion of pathogens, and by virtue of its oxidative properties, it can break the structure of pathogens and inhibit their growth and reproduction.
However, if there is too much hydrogen peroxide, it will harm the growth and reproduction. It can cause oxidative stress in cells, damage cell membranes, proteins and nucleic acids. Cell membranes are the barrier of cells. Hydrogen peroxide can cause membrane lipid peroxidation, rupture of membrane integrity and fluidity, and hinder cellular material transportation and signal transduction. Proteins are oxidized by it, conformational changes, loss of activity, impairment of the functions of many enzymes, and cell metabolism disorders. As for nucleic acids, hydrogen peroxide can cause base modification, chain breakage, abnormal gene expression, or cell carcinogenesis and apoptosis.
The mechanism by which cells respond to hydrogen peroxide has an antioxidant defense system. Intracellular superoxide dismutase, catalase, glutathione peroxidase, etc. can cooperate to remove hydrogen peroxide and maintain the redox balance in cells. However, when hydrogen peroxide is generated too much, the defense system may be overwhelmed and the cell will be damaged.
In short, the impact of hydrogen peroxide on cells has both advantages and disadvantages. Understanding its mechanism is of great significance in disease diagnosis and treatment and biomedical research. Doctors can explore new treatments according to their reasons; researchers can use this to investigate the mysteries of cells and promote biomedical progress.
