A new frontier in cancer research is emerging from the MUSC Hollings Cancer Center, where Dr. Aguirre de Cubas is pioneering groundbreaking strategies to enhance the treatment of kidney cancer. With his receipt of a Department of Defense Academy of Kidney Cancer Investigators Early Career Scholar Award, Dr. de Cubas aims to harness the power of the immune system, pushing its boundaries to identify and obliterate cancerous renal tumors. This award, established by Congress in 2017, seeks to advance research initiatives that hold immense potential and exceptional scientific merit.
Dr. de Cubas’s focus is on renal cell carcinoma, which represents the most prevalent type of kidney cancer. This form of cancer often goes undiagnosed until it reaches an advanced stage, which significantly diminishes the chances of survival. Unfortunately, current statistics reveal that at the time of diagnosis, as many as 30% of patients already present with metastatic disease, and these individuals face disheartening five-year survival rates of merely 12%. The recent development of immune checkpoint inhibitors has revolutionized cancer therapy, acting as a means to “release the brakes” that restrain the immune system from efficiently combating tumors. Yet, despite these advancements, lasting responses remain limited, with only one in five individuals experiencing significant and enduring improvements following treatment for metastatic renal cell carcinoma.
In his quest to enhance the immune system’s ability to recognize and eliminate cancer cells, Dr. de Cubas employs a transformative tool: mitochondrial DNA. Found within the powerhouses of cells known as mitochondria, this genetic material can serve as an alarm system for the immune response. When mitochondria are compromised, the consequent release of DNA fragments into the cytoplasm conveys a signal akin to that of a viral infection, thus activating the immune system into recognizing a threat. Nevertheless, many cancers have developed mechanisms to inhibit this alert system, allowing tumors to evade immune detection.
To counteract this evasion, Dr. de Cubas utilizes innovative strategies that mimic the signs of viral infection, thereby triggering an immune response toward the afflicted cancer cells. A pivotal aspect of his methodology is centered around targeting a specific protein known as BCL-XL. By damaging mitochondria through this protein, he encourages the release of mitochondrial DNA fragments. This response reinstates the immune system’s alert mechanism, effectively unveiling the previously camouflaged tumors.
The ultimate objective of Dr. de Cubas’s research is to forge an innovative combination therapy. This approach intends to not only make tumors more conspicuous to the immune system but also to eliminate the restraining barriers that inhibit its efficacy in combating cancer. By achieving this dual action, he envisions a more robust immune attack on kidney cancer, significantly improving patient outcomes.
Dr. de Cubas acknowledges the critical role of the South Carolina Disparities Research Center (SC CADRE) in propelling his research career. This collaborative effort, funded by the National Cancer Institute, has been operating for 13 years and acts as a vital partnership between MUSC Hollings Cancer Center and South Carolina State University, a historically Black institution. SC CADRE seeks to cultivate a diverse generation of cancer researchers who are adept in tackling health disparities and improving cancer outcomes for South Carolinians.
Under the co-direction of Marvella Ford, Ph.D., who holds the Endowed Chair in Cancer Disparities, and Judith Salley-Guydon, Ph.D., who chairs the Biological and Physical Sciences Department at SCSU, SC CADRE’s mission is to equip emerging scientists like Dr. de Cubas with the necessary tools and resources. This initiative not only aids in securing preliminary data but also strengthens collaboration among researchers. Dr. de Cubas lauds SC CADRE for its instrumental role in transitioning his early research ideas into substantial concepts positioned for funding and expansion.
The DOD award securing Dr. de Cubas’s position as an independent researcher exemplifies the significance of partnerships between research organizations and community-centric initiatives in the pursuit of cancer treatment advancements. By aligning advanced research expertise with community-focused efforts, SC CADRE fosters an environment where new methodologies in cancer treatment can develop, opening doors for a diverse spectrum of scientific inquiry.
As Dr. de Cubas embarks on establishing his own independent laboratory, his pioneering approaches stand to illuminate pathways toward more effective cancer therapies. The intersection of advanced research and community engagement serves not only to advance awareness about kidney cancer but also inspires a new generation of scientists committed to addressing the multifaceted challenges posed by this disease.
Ultimately, Dr. de Cubas’s work represents a beacon of hope for kidney cancer patients. By reinvigorating the immune system’s capacity to recognize and respond to cancerous cells, he is laying the groundwork for transformative therapies that could redefine the landscape of cancer treatment in the years to come.
This flourishing area of study mirrors the evolving nature of cancer research, where innovative ideas meet pragmatism to develop tangible solutions for those afflicted. The ongoing collaboration with organizations like SC CADRE ensures that the future of cancer care will be inclusive, equitable, and driven by scientific excellence, which is the cornerstone of transformative healthcare interventions.
As Dr. de Cubas continues to navigate uncharted waters in cancer research, the journey holds the promise of not just prolonging lives but enhancing the quality of life for kidney cancer patients everywhere. In this pursuit, the marriage of science, community engagement, and personal dedication paints an optimistic picture for the future of cancer treatment.
