Dr. Perry [Damon Runyon-Lois A. Cinelli Awardee supported by the Cinelli Family Foundation] is investigating how a key immune cell in the tumor microenvironment, the macrophage, contributes to cancer’s development and progression. His work focuses on triple-negative breast cancer, as it remains one of the deadliest cancers, especially to young women and Black women, with decades of treatment efforts failing to improve patient outcomes. Specifically, Dr. Perry aims to combine novel methods of manipulating and imaging the cellular metabolism to better understand how macrophages contribute nutrients to help cancer cells meet their nutrient demand and escape treatment. This work will not only provide a method for diagnostic biomarker identification but also establish a novel platform for developing individualized treatments. Importantly, his work has the potential of being broadly applicable to all difficult-to-treat metastatic adenocarcinomas.

Most cancers develop in the epithelial tissue, which includes the skin and internal organ linings.  Hemidesmosomes (HDs) are adhesive structures that anchor epithelial cells to the underlying base layer and maintain tissue integrity. While HD disassembly occurs normally during wound healing, tumor cells can exploit this process to detach and spread to other parts of the body. Dr. Bagde is studying how HD components interlock like Lego blocks to form stable HDs in healthy tissues and how they disassemble in cancerous tissues. To investigate this phenomenon, Dr. Bagde plans to develop organoids—self-organizing mini-organs grown in a petri dish to study disease progression. By creating simple base layers that simulate the supportive properties of the native organ base layer, he plans to promote the growth of both normal and cancerous organoids. This work has the potential to support the development of personalized cancer therapies based on patient-derived tumor samples. Dr. Bagde received his PhD from Cornell University, Ithaca and his MS and BS from the Indian Institute of Science Education and Research, Pune.

Some breast cancers and most prostate cancers express high levels of androgen receptors. Curiously, both activation and inhibition of androgen receptor signaling can result in tumor shrinkage, and the molecular mechanisms driving these opposing effects remain unclear. By studying circulating tumor cells from the blood, Dr. Dai and his colleagues found that this paradoxical effect is mainly caused by abnormal binding of androgen receptors to DNA, changing its three-dimensional structure and resulting in the shutdown of a key cancer gene called MYC. Dr. Dai may have discovered a way to therapeutically target MYC, which has long been a challenging drug target, by overactivating androgen receptors to disrupt the DNA structure required to keep MYC turned on. This could be a promising new strategy to treat certain breast and prostate cancers. He is now investigating why this effect occurs, and how many cancers could be treated this way. Dr. Dai’s research could lead to a new approach to cancer treatment: activating androgen receptors to disrupt the genes that cancers rely on to grow.

The cellular response to DNA damage is coordinated by an enzyme known as ATM kinase. Mutations in ATM are found in approximately 1% of the population and contribute to an increased risk of both hereditary and sporadic cancers, including breast cancer. Dr. Kim’s research investigates how ATM suppresses the production of double-stranded RNAs (dsRNAs) in response to DNA damage. These dsRNAs play a critical role in tumor progression. Dr. Kim aims to identify the key molecular players involved in ATM-mediated suppression of dsRNAs and elucidate how the loss of ATM function triggers inflammatory responses through dsRNA sensing pathways. By uncovering these mechanisms, Dr. Kim aims to deepen our understanding of how ATM mutations drive cancer development and uncover novel therapeutic strategies for ATM-associated cancers. Dr. Kim received his PhD and BS from the Ulsan National Institute of Science and Technology, Ulsan.

“Bone-deep pain” is more than a metaphor. Bones and joints are constantly monitored by sensory neurons (nociceptors) that detect damage and trigger protective pain responses. However, in bone cancer and osteoarthritis, this pain can become chronic and debilitating—especially when the bone’s rich environment is colonized by migrating metastatic tumor cells originating in the prostate, breast, or lung. Dr. Martin’s [Connie and Bob Lurie Fellow] research aims to uncover how skeletal sensory neurons are activated and remodeled in these conditions. Using neurophysiology techniques, she is mapping how skeletal neurons respond to potential triggers and testing a new hypothesis: that these neurons not only detect tumors but also influence their growth. This work may uncover new strategies for treating chronic skeletal pain. Dr. Martin received her PhD from the University of Chicago, Chicago, and her BS from St. John’s University, New York.

Mitochondria are best known as the cell’s power plants, but they also help cells respond to stress and repair their own DNA. A mitochondrial protein called ATAD3A plays a key role in these processes and is found at abnormally high levels in many aggressive cancers such as glioblastoma, breast cancer, and colorectal cancer, where it contributes to tumor growth and resistance to treatment. Dr. Orta studies how ATAD3A acts as a sensor of mitochondrial DNA damage—detecting trouble inside the mitochondria and helping signal to other parts of the cell, like the endoplasmic reticulum, that stress responses are needed. Using cryo-electron microscopy along with biochemical and cell-based approaches, she aims to uncover how ATAD3A is regulated and how its function supports cancer cell survival. Ultimately, she hopes to expose new ways to target mitochondrial stress pathways in cancer. Dr. Orta received her PhD from California Institute of Technology, Pasadena, and her BS from the University of Texas at El Paso, El Paso.

Human cells compact their vast genomes into the small confines of the nucleus by wrapping their DNA into a highly complex structure called chromatin. Packaging DNA into chromatin, however, affects all nucleic acid-transacting machines (e.g., transcription factors) that need to access the genomic information stored in the DNA. NuRD is a large multi-subunit protein complex that plays a major role in making chromatin either accessible or inaccessible. Dysregulation of NuRD and aberrant targeting of the complex can result in the emergence of several types of cancers, including breast, liver, lung, blood, and prostate cancers. Dr. Osorio Valeriano’s [Philip O'Bryan Montgomery, Jr., MD, Fellow] work will reveal mechanistic aspects of NuRD-mediated chromatin regulation and pave the way for the development of novel therapeutic approaches that target cancers more effectively. Dr. Osorio Valeriano received his PhD from Philipps University and his MSc and BSc from the National Autonomous University of Mexico.

In order to survive, cancer cells must evade or disable the immune system. Many cancers are caused by chronic infection with viruses that modulate the host cell by influencing gene expression to achieve this same goal. Dr. Pasquarelli Rios [HHMI Fellow] is studying how viral proteins alter gene expression to create a tumor microenvironment that prevents the immune system from killing cancer cells. Since many viral proteins achieve this by changing the expression of secreted proteins, which can be therapeutically targeted, Dr. Pasquarelli Rios is also exploring the effect of secreted proteins on tumor immune evasion. This work will deepen our understanding of how cancers evade the immune system and has the potential to uncover new targets for cancer treatment. Dr. Pasquarelli Rios received her PhD from the University of California, Los Angeles, and her BS from Brown University, Providence.

Groundbreaking advances in immunotherapy have revolutionized the treatment of cancer. In particular, new antibody drugs that block immunosuppressive pathways have achieved remarkable success in reawakening the immune system to clear tumor cells, leading to lasting cures in patients whose cancers do not respond to any other therapies. Unfortunately, the majority of patients (>70%) do not respond to immunotherapy treatment. It is difficult to predict which patients will benefit, creating an urgent demand for novel immunotherapy drugs that act through alternative mechanisms. Dr. Spangler is working to develop a class of antibody therapeutics that target cancer-promoting pathways in a different way than all current immunotherapies, with the goal of drastically expanding the percentage of cancer patients who benefit from them.
