According to a study published in the journal Cell, scientists have discovered that cancer cells enter a 'hibernation mode' to resist chemotherapy. In this Zogen blog post, we tell you more about the study, its implications, and how it could affect cancer treatment. cancer It is a disease characterized by the uncontrolled growth of abnormal cells in the body. Unlike normal cells, which grow, divide, and die in an orderly fashion, cancer cells continue to divide uncontrollably, which can form masses called tumors (except in some types of cancer such as leukemia, which do not form solid tumors).
How does cancer develop?
Cancer begins when a cell's DNA is damaged mutations or changes that alter their normal functioning. These mutations can be caused by genetic or environmental factors, such as:
- Exposure to tobacco
- Radiation
- Carcinogenic chemicals
- Viral infections (such as HPV or hepatitis B and C)
- Hereditary factors
What do cancer cells do?
- They grow uncontrollably
- They invade nearby tissues
- They can spread to other parts of the body (metastasis) through the lymphatic system or the bloodstream
Most common types of cancer
- Carcinomas: They affect organs or glands (breast, lung, prostate, etc.)
- Sarcomas: They originate in bones, muscles, or connective tissues.
- Leukemias: They affect the blood and bone marrow
- Lymphomas and myelomas: They affect the immune system
New discoveries
In a surprising scientific advance, published in the journal Cell, Researchers have identified that cancer cells can enter a hibernation-like state to survive the effects of chemotherapy. This discovery could change how cancer is treated, opening new avenues for more effective therapies.
How does this 'hibernation mode' work?
Cancer cells, when faced with the stress of chemotherapy, reduce their metabolic activity to a minimum, similar to how some animals hibernate to survive extreme conditions. This state allows them to resist the damage caused by the drugs, which explains why some cancers can recur after successful treatment.
Recent studies published in renowned scientific journals, such as Nature y Cell Reports, Scientists have demonstrated this phenomenon by observing cancer cells in the laboratory and in animal models. They discovered that by reducing their metabolism, these cells enter a state of dormancy that makes them less vulnerable to the effects of chemotherapy drugs. A study led by Dr. Cédric Blanpain of the Free University of Brussels revealed that this dormant state is regulated by specific genetic mechanisms that allow the cells to "pause" their growth and reactivate once the environment becomes favorable again.
Implications for cancer treatment
The discovery that cancer cells enter a state of 'hibernation' to resist chemotherapy has significant implications. Scientists are exploring how to disrupt this process so that cancer cells cannot evade treatment. This could lead to the development of new therapies that prevent cells from entering this dormant state. For example, some researchers are testing drugs that can 'wake up' dormant cells, making them more susceptible to traditional chemotherapy.
The role of genomic testing in the detection of these cells
Genomic tests are key tools for identifying mutations and genetic patterns in cancer cells. With this new discovery, they could play a crucial role in detecting cells in 'hibernation mode,' enabling more personalized and effective treatments. These tests allow for the identification of alterations in genes related to treatment resistance, providing oncologists with valuable information for adjusting therapeutic strategies.
Conclusion
The fact that cancer cells enter 'hibernation mode' to resist chemotherapy highlights the need for more sophisticated approaches in the fight against cancer. At zogen, we remain committed to facilitating access to advanced genomic tests that help physicians better understand cancer behavior and design personalized treatments for each patient. This scientific advancement underscores the importance of ongoing research to improve success rates in combating this disease.
