A recent study has found a way to track each step of a healthy cell as it becomes cancerous. Researchers were able to study the “genes and molecules involved in each step.”
The researchers provoked genomic instability in the cells of the fruit fly’s wing, or the Drosophila melanogaster, and allowed these cells to withstand the organism’s natural defenses. The scientists were able to see the cancer spreading throughout the cell and invading nearby organelles and cell structures. According to one scientist, Andres Dekanty, “for the first time we have a genetic model that allows us to understand the events that take place, starting from when cells begin to accumulate genomic errors until the development of a tumor.”
Furthermore, the researchers at the Institute for Research in Biomedicine believe that their research will be important for determining if cancer is caused by genomic instability. If this proves to be true, scientists and doctors will have a specific target to study, and to treat.
Researchers believe that the key to curing caner is identifying the difference between normal, healthy cells and a cell with genomic instability. Dekanty hopes that since “there isn’t a treatment available that attacks only the cells with genomic instability, if we can clearly differentiate one from the other, we’ll hopefully be able to find drugs that target them specifically.”
This study is of major importance because today, cancer treatments, such as chemotherapy have many side effects because they aim to stop cell division in both infected and healthy cells. New, more precise treatments could stem out of this study.
