Cancer patients could benefit from a groundbreaking discovery that reveals a ‘vital weak spot’ in the devastating disease, according to experts. Recent findings have established a previously unknown link between DNA and the effectiveness of immunotherapy, a type of treatment used to combat certain types of cancers. Immunotherapy utilizes drugs that harness the body’s natural defenses to attack cancer cells.
Scientists have made an exciting breakthrough that could potentially enhance the drug’s effectiveness. They have uncovered the significance of DNA in the ‘energy factories’ residing within tumors. Mitochondria, the special compartments responsible for generating energy within living cells, may hold the key to improving the drug’s response rate. Through strategic DNA rewiring, experts have demonstrated that tumors can become up to two and a half times more susceptible to the effects of the commonly used immunotherapy drug, nivolumab.
Immunotherapy mainly operates by inhibiting the immune system ‘brake’ that prevents attacking cancer cells. The studies have shown that tumors with high levels of mitochondrial DNA mutations exhibited an increased response rate of up to two and a half times to nivolumab. This discovery could aid doctors in predicting the patients who would benefit the most from immunotherapy, potentially revolutionizing cancer treatments.
Beyond prediction, researchers also suggest that replicating the effects of DNA mutations could render treatment-resistant cancers more vulnerable to immunotherapy. With this approach, thousands more cancer patients could avail themselves of these life-saving drugs.
Advancements in Cancer Treatment
Immunotherapy, an innovative cancer treatment that utilizes the body’s immune system, has emerged as a powerful tool in the fight against cancer. Typically applied in lung, cervical, head and neck, and liver cancers, it promotes the body’s recognition and attack of cancer cells. Immunotherapy can either be utilized as a standalone treatment or in combination with other therapies such as chemotherapy and radiotherapy.
Professor Dr. Payam Gammage, Co-lead Author and Group Leader at the Cancer Research UK (CRUK) Scotland Institute and the University of Glasgow, explained, “Cancer is a complex disease that challenges our immune system’s ability to identify and destroy cancer cells, as they may resemble healthy cells. Our research showed that tumors with the most mutated mitochondrial DNA exhibited heightened sensitivity to immunotherapy.”
This research breakthrough has allowed Cancer Research Horizons, the innovation arm of CRUK, to file patents for the technology underlying this discovery. These patents will pave the way for the development of novel treatments that disrupt the energy sources exploited by cancer cells to grow and spread.
Promising Future Ahead
Dr. Iain Foulkes, Executive Director of Research and Innovation at CRUK and CEO of Cancer Research Horizons, stated, “The identification of mitochondrial DNA mutations holds immense potential in targeting cancer. After years of dedicated laboratory research, we have found a critical vulnerability in cancer. Thanks to this remarkable discovery, we can approach cancer treatment through an entirely new perspective, opening up endless possibilities.”
Dr. Ed Reznik, who also contributed to this study at the Memorial Sloan Kettering Cancer Center, shared his enthusiasm, saying, “This research opens up new avenues in which we can disrupt tumor energy sources. By potentially short-circuiting them, we can make powerful advancements in cancer treatment.”
The findings, published in the prestigious journal Nature Cancer, represent a significant development in cancer research, offering renewed hope to those fighting this battle.
