HydrogenPeroxideCancerCausing
In recent times, medical pharmacology research has deepened, and there are many opinions on the properties and uses of hydrogen peroxide, among which the theory of its carcinogenicity is particularly eye-catching.
Hydrogen peroxide has the formula\ (H_ {2} O_ {2}\), which has strong oxidative properties. It often exists in nature and is metabolized by organisms. In the past, it was widely used in medical and health fields because of its ability to disinfect and sterilize. However, today's research has gradually suspected that it is related to carcinogenesis.
The reason is that hydrogen peroxide can cause oxidative stress in cells. When cells are exposed to hydrogen peroxide, a large number of reactive oxygen species (ROS) can be produced. ROS has high reactivity and can damage various biological macromolecules in cells, such as DNA, proteins and lipids. If DNA is damaged, its base pairs can be mutated, deleted or mismatched. Over time, the stability of cell genes is broken, and cell proliferation and differentiation are disordered, gradually threatening to become cancerous.
Furthermore, hydrogen peroxide can affect cell signal transduction pathways. Cell growth, differentiation and apoptosis depend on precise signal transduction regulation. Hydrogen peroxide can interfere with this regulation, causing abnormal activation of pro-cancer signals and suppression of tumor suppressor signals. For example, MAPK and NF-kappa B and other pathways are often abnormally activated when encountering hydrogen peroxide, causing abnormal cell proliferation and paving the way for cancer.
However, some commentators have refuted it. It is said that organisms have their own antioxidant defense system, which can resist the harm of hydrogen peroxide. Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), etc., can convert hydrogen peroxide or ROS into harmless substances. And under normal physiological conditions, the concentration of hydrogen peroxide in cells is low and does not cause serious damage.
In summary, the theory that hydrogen peroxide causes cancer has not been conclusively proven to be related. We should take a cautious attitude, deepen our research, clarify its accuracy, and provide a solid basis for medical and health practice and the cause of cancer prevention and anti-cancer.
