Found a way to fight cancer without harm to the body

Depending on the type of cancer and type of treatment,the patient can suffer from many side effects, including anemia, loss of appetite, bleeding, fatigue, hair loss, nausea, and so on. However, a group of researchers from the University of Oregon, the University of Central Florida and New York University made a discovery by which it is possible to develop methods for treating a dangerous disease that will not cause complications from antitumor therapy.

Why do tumors grow

As you know, a hallmark of behaviortumor cells is their uncontrolled growth. Tumor cells must constantly receive energy and create building proteins for replication. Due to the rapid metabolism inside the cells, their growth occurs. And studying these processes with the development of type 2 neurofibromatosis - a hereditary disease that causes the development of benign tumors in the nervous system, scientists from the USA came to unusual conclusions.

According to the editors of the Journal ofBiological Chemistry, researchers led by Professor Mac Franco, have discovered that tumor cells reproduce an oxidizing agent and a specific nitrating agent (peroxynitrite). They affect the amino acid composition of the body’s proteins, and specifically tyrosine. When tyrosine is altered, it “reprograms” cells for faster energy production.

To maintain constant growth, tumorcells are changing the way they produce energy and building proteins. We found that peroxynitrite, the most powerful oxidizing agent produced by cells, controls the metabolic changes that occur in the tumor cells of the nervous system, which supports their growth. We believe that there are specific proteins that acquire a new function that they did not have before, and this new function can control tumor growth.

Moreover, in normal, not affected by tumorthe process of tissues, peroxynitrite is not produced. Moreover, it is precisely because of peroxynitrite that healthy cells are often affected, which can lead to the development of significant complications during the course of the disease.

This discovery gives us a great opportunity.developing a new therapeutic strategy in the treatment of cancer. We only need to understand how to slow down or even stop the production of peroxynitrite. If this succeeds, then we will have a great opportunity not only to effectively stop the growth of the tumor, but also to do it with minimal side effects for the whole organism.
