Each of us has "oncogenes" in our bodies, but most people's "oncogenes" have not been activated in their lifetime.

     Xiao Nan first came into contact with this knowledge in the high school biology textbook. Like everyone else, he was shocked at the time! It turns out that dangerous oncogenes accompany us all the time to eat, drink and sleep...

        With the acceleration of the pace of social development, environmental degradation has become more and more serious, the people's life pressure has continued to increase, and the growth rate of malignant tumors in China has increased year by year. These blinking numbers and grim reality have made cancer, the devil that destroys human health, even more terrifying. Fortunately, our body and the immune system are guarded by the "iron warriors", and they are not vulnerable. In the long journey of fighting cancer, how to prevent cancer and prevent the activation of cancer genes is what everyone must understand. Knowledge.

Proto-oncogene and tumor suppressor gene

    The oncogene precursor in the human body is called "proto-oncogene". As the name suggests, it is a gene that induces cell carcinogenesis. The medical concept is a nucleotide fragment that is highly similar to oncogene in normal cell tissues. The expression product of proto-oncogene is related to the growth, proliferation, differentiation and regulation of normal cells. In normal individuals, the gene is in a low expression or quiescent state and is not harmful to the cell. Once activated, the cell will become cancerous;

    Proto-oncogenes do not exist alone. Correspondingly, there are also tumor suppressor genes that "bundle" proto-oncogenes in normal humans. As the name suggests, they are genes that inhibit the expression of proto-oncogenes and can curb tumors by inhibiting cell proliferation and growth. generate.

    The protocarcinoma and tumor suppressor genes are in a state of expression balance. Once the balance is broken and the protooncogene is greater than the tumor suppressor gene, the cell will become cancerous! Carcinogenic factors are the "key" that initiates the growth of cancer cells, and we must remove this key.
