Rare earth: cancer nova
Rare earth: cancer nova
China has abundant rare earth resources and various kinds. Rare earth elements include 17 elements including lanthanum, cerium, praseodymium and neodymium. In recent years, rare earth has not only been widely used in agriculture, science and technology, defense, etc., but also demonstrated its encouraging application prospects in the medical field.
The epidemiological investigation showed that the incidence of tumor of rare earth workers was significantly lower than that in the control group. Animal experiments also found that after long-term irrigation of rare earths, mice were observed to have a significant inhibitory effect on the transplanted sarcomas. Further research also confirmed that the rare earth elements on the one hand, can be against many kinds of human tumor cell lines (such as breast, lung, stomach cancer, leukemia, etc.) the growth and proliferation, and can promote the growth of normal cells on the other hand, it is for application of rare earth in provides experiment basis for tumor treatment.
So what is the mechanism for rare earth cancer? Most studies suggest that there are several main aspects:
The rare earth has a strong affinity for cancer tissues, and the combination of rare earth and cancer can interfere with the metabolism of cancer cells and the synthesis of DNA (DNA).
Rare earth is like a pair of "scissors", the shear nucleic acid chain can be h ydrolyzed and fractured.
The rare earth can selectively destroy the ultrastructure of the cells that are malignant or cancerous.
The rare earth can inhibit the expression of oncogene expression and enhance the expression of tumor suppressor genes.
Although the study of the anti-tumor mechanism of rare earth is still under discussion, statistics show that radioactive rare earths account for half of the radioactive elements that treat cancer. In addition, medical researchers are now working on the use of rare earths for AIDS treatment. Adachi edition university professor Yin to the work as well as the highly: "to extend the function of rare earths to achievements in the field of biology, such as can with rare earth catalyst in medicine cut AIDS and cancer genes, will be the humanity's greatest blessing."
As far as AIDS and cancer are concerned, the rare earth shock will greatly exceed the rare earth oxides high temperature superconductors that occurred in previous years. It is believed that in the 21st century, when the cancer and AIDS are conquered, the rare earths - the new cancer star - will shine.
