Template for selective drugs to kill cancer cells

Scientists have successfully prepared a sample of a drug based on ribonucleic acid (RNA), which allows to selectively destroy cancer cells without harming the health of patients.

According to the work published in the journal Proceedings of the National Academy of Sciences , these drug models help avoid the side effects of chemotherapy that patients currently undergoing cancer have to undergo.

The basis of this drug template is primarily made up of tiny RNA molecules, called small auxiliary RNA molecules, that perform various and repeated functions in the body daily. human life.

Scientists explain that each type of cancer has its own unique characteristics and that practically every patient can choose their own suitable drug on the basis of RNA, allowing selective destruction for malignant cells .

The scientists used the study to prepare this template from cancer cells carrying the deoxyribonucleic acid (DNA) mutation, expressed in their RNA molecule. These molecules can be unique patterns, allowing differentiation of cancer cells from benign cells.

In separate ways, in the process of interacting with similar patterns, tiny synthetic auxiliary RNA molecules can mutate (self-evolve) and change their structure. This structural change results in a chain reaction of tiny auxiliary RNA molecules with long chain structures.

The process of self-recognition of the cell and the transmission of the virus creates within it immunity as well as the mechanism of self-destruction of malignant cells. In the process of " meeting " with healthy cells will not occur the evolution of these auxiliary RNA molecules and healthy cells will remain intact.

Now scientists have to prove the therapeutic effect of this drug on the living organism instead of just experimenting on artificial cancer cells, then we can hope for methods. Cancer treatment with a new drug template.

Nucleic acid is a biological macromolecule with a large molecule made up of nucleotide chains to transmit genetic information. The two most common nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
