The 48th Annual UNC Lineberger Scientific Symposium stands as a pinnacle event in the ongoing battle against cancer, convening leading researchers, clinicians, and population scientists in Chapel Hill, North Carolina. This year’s symposium not only marks a day-and-a-half of rigorous scientific discourse but also commemorates the 50th anniversary of UNC Lineberger’s esteemed designation as a National Cancer Institute (NCI)-designated cancer center. It serves as a crucial platform where cutting-edge discoveries across the molecular, clinical, and population health spectra are synthesized and disseminated to foster improved patient outcomes.
Central to this symposium is the exploration of protein kinase specificity, a subject extensively addressed by Lewis Cantley, PhD, from the Dana-Farber Cancer Institute. Protein kinases, enzymes critical in cell signaling and regulation, have emerged as pivotal modulators in oncogenesis. Cantley’s discourse elucidates the intricate biochemical networks underpinning kinase activity, emphasizing the therapeutic potential locked within their cellular regulatory mechanisms. This nuanced understanding paves the way for the development of more precise kinase inhibitors, curbing cancer cell proliferation and resistance.
Genomic disparities and their implications on cancer outcomes form a vital theme of the meeting, articulated by Melissa B. Davis, PhD, from Morehouse School of Medicine. Her presentation delves into the systemic inequities embedded within genomic datasets and the consequent population-level cancer disparities. Highlighting the necessity for inclusive genomic research, Davis underscores the role of tailored therapeutic interventions that address the unique molecular profiles of historically underrepresented groups, aiming to reduce the cancer burden equitably across diverse populations.
Another groundbreaking topic is the elucidation of RAS oncogenic signaling pathways and their immune evasion strategies, expertly presented by Julian Downward, PhD, of the Francis Crick Institute. RAS proteins, notorious for their role in driving oncogenesis, have historically been deemed “undruggable” due to their structural complexity. Downward’s insights into the modulation of immune checkpoints and intracellular signaling networks offer promising avenues for therapeutic innovation targeting these elusive oncoproteins, potentially revolutionizing treatment paradigms for RAS-driven malignancies.
The symposium also honors four decades of research on tyrosine phosphorylation, conveyed by Tony Hunter, PhD, from the Salk Institute. Tyrosine phosphorylation, a critical post-translational modification, orchestrates myriad cellular processes including growth and differentiation. Hunter’s retrospective and forward-looking analysis highlights how decades of fundamental biochemical research have culminated in the development of tyrosine kinase inhibitors that have transformed the therapeutic landscape for multiple cancer types, illustrating the profound impact of basic science on clinical advances.
William G. Kaelin Jr., MD, also from Dana-Farber Cancer Institute, addresses the enigmatic VHL (von Hippel-Lindau) tumor suppressor protein. His presentation navigates the complexities of targeting the “undruggable,” focusing on how understanding the VHL pathway’s regulatory role in hypoxia-inducible factors offers unprecedented therapeutic strategies. The molecular intricacies unravelled here hold immense promise in devising treatments that disrupt tumor growth in cancers characterized by VHL inactivation.
Edison T. Liu, MD, of The Jackson Laboratory, brings attention to triple-negative breast cancer (TNBC), a particularly aggressive subtype lacking targeted hormonal therapies. His genomic biology analysis probes the mutational landscape and heterogeneity of TNBC, revealing potential biomarkers and targets for innovative therapies. By integrating genomic sequencing data with clinical phenotypes, Liu’s work exemplifies the precision oncology approach that strives to tailor interventions to the unique genetic makeup of each tumor.
Elaine Mardis, PhD, from The Ohio State University, highlights the genomic diversity observed in acute myeloid leukemia (AML) among Black patients. This focus on genetic variability elucidates treatment outcome disparities and underscores the necessity of incorporating diverse populations in genomic studies. Mardis’s research advocates for personalized medicine strategies that account for racial and ethnic differences in cancer genomics, seeking to optimize therapeutic efficacy and equity.
Continuing at The Ohio State University, W. Kimryn Rathmell, MD, PhD, intriguingly contextualizes the historic and prospective trajectory of UNC Lineberger as a model for comprehensive cancer care. Rathmell’s insights weave together translational research, clinical innovation, and public health initiatives, underscoring the institution’s multifaceted approach to combating cancer. This holistic model exemplifies how integrated efforts enhance patient care and accelerate the translation of discoveries from bench to bedside.
From a public health perspective, Kurt M. Ribisl, PhD, of the UNC Gillings School of Global Public Health, advocates for interdisciplinary strategies in cancer prevention. His discourse emphasizes leveraging epidemiology, behavioral science, and policy to formulate concerted interventions that address cancer risk factors at the population level. Ribisl’s work highlights the critical interface between science and community health, illustrating the importance of preventative frameworks in reducing cancer incidence.
Arlene Sharpe, MD, PhD, of Harvard Medical School, explores the revolutionary use of CRISPR technology in discovering new immunotherapy targets. Her expert analysis demonstrates how genome editing accelerates the identification of molecular pathways that can be manipulated to enhance immune recognition and destruction of cancer cells. Sharpe’s contributions underscore the transformative potential of combining genetic engineering with immuno-oncology to develop next-generation therapies.
Kevan Shokat, PhD, from UC San Francisco, confronts the formidable challenge of drugging K-Ras, a dominant oncogene implicated in numerous cancers. Shokat’s research highlights innovative chemical biology techniques and allosteric modulation approaches that have begun to dismantle previous barriers in targeting K-Ras. His work represents a significant stride towards effective therapeutics against notoriously resistant oncogenic drivers.
Additionally, Melissa Troester, PhD, and Stephanie B. Wheeler, PhD, MPH, both from UNC Gillings School of Global Public Health, champion collaborative frameworks and multimodal data integration to optimize breast cancer care. Troester focuses on harnessing diverse data types—including genomic, histopathologic, and clinical information—to refine prognostic accuracy and treatment personalization. Meanwhile, Wheeler underscores community-engaged approaches and policy initiatives aimed at enhancing cancer care equity within North Carolina.
Kwok-Kin Wong, MD, PhD, of NYU Langone Health, addresses targeted therapeutic strategies for lung squamous cell carcinoma. Highlighting molecular vulnerabilities, Wong’s presentation sheds light on precision medicine approaches that improve outcomes for patients afflicted with this challenging lung cancer subtype.
Finally, Yue Xiong, PhD, from Cullgen Inc., discusses targeted protein degradation as an emerging therapeutic platform. This novel modality leverages the cell’s intrinsic degradation machinery to selectively eliminate oncogenic proteins, presenting a paradigm shift that holds promise across various cancer types.
Collectively, the 48th Annual UNC Lineberger Scientific Symposium integrates an impressive array of scientific advancements and multidisciplinary insights. By traversing molecular biology, clinical research, and population health, the symposium reaffirms its foundational mission: harnessing the full spectrum of cancer research to forge pathways for improved patient outcomes worldwide. Furthermore, the event’s accessibility through livestream and free registration underscores its commitment to disseminating knowledge broadly, fostering global collaboration in the fight against cancer.
