Interoceptive neural circuits are responsible for sensing internal changes in the body and initiating appropriate responses. In the context of female reproduction, these neurons sense internal states within the reproductive tract and maintain homeostasis by modulating functions like smooth muscle contractions, fluid flow, and communication with the central nervous system. The female reproductive tract undergoes major changes throughout life, ranging from pregnancy to gynecological cancers like high-grade ovarian carcinoma. Dr. Greenberg is investigating how interoceptive neurons monitor the female reproductive tract and modulate essential physiologies in these changing hormonal and biological states. Her research on the typical functions of reproductive neurons and on the neuronal contribution to tumor progression may suggest novel therapeutic approaches for gynecological cancer treatment.

There are two key types of cancerous mutations: one that turns on growth signals too strongly, like a car with a stuck accelerator, and the other that turns off safety mechanisms, like a car with broken brakes. While some cancers can be treated with drugs that block overactive growth signals—such as Gleevec for chronic myeloid leukemia—there are currently no effective treatments for cancers caused by the loss of these safety mechanisms, also known as tumor suppressor genes. Notably, mutations in TP53, one of the most common tumor suppressor genes, are abundant in almost all cancers, including breast, lung, and ovarian cancers. Dr. Zheng’s research focuses on reactivating these impaired tumor suppressor genes, such asTP53and FBXW7, to develop new treatment options for a wider range of cancers and to address resistance to existing therapies.

Dr. Thawani studies how so-called “selfish DNA” elements copy and paste themselves within the human genome. Using advanced methods such as cryo-electron microscopy to reveal the atomic structures of various molecules associated with these selfish elements, she aims to delineate their mechanism of mobility. She is also interested in understanding how selfish DNA elements are recognized and silenced within the human genome. Dr. Thawani plans to harness these discoveries to engineer new genome editing technologies to precisely insert large genes at user-specified sites in a variety of human cell types. This general technology will translate directly into new gene therapy tools that will enable treatment of loss-of-function genetic diseases, including many cancer types, and provide a path to improving CAR-T therapies for blood cancers.

Dr. Liu’s research focuses on discovering new drug candidates to treat pancreatic, colorectal, breast, and prostate cancers. Using advanced computational techniques to screen billions of chemical compounds, she aims to identify and develop highly specific molecules that target critical pathways in cancer cells while sparing healthy tissues. For example, she has uncovered compounds that modulate calcium-sensing receptors, which play a role in certain cancers, with reduced side effects compared to the current standard-of-care. She is now applying these insights to improve treatments that boost immune responses against tumors. Dr. Liu’s work not only strives to create new cancer therapies but also deepen our understanding of the complex interactions within tumors, paving the way for precision medicine tailored to individual patients.

Dr. Gu’s [Sijbrandij Foundation Breakthrough Scientist] lab studies how cells regulate the destruction of proteins without using the typical "ubiquitin" tag, which signals that a protein should be transported to the proteasome for digestion and recycling of amino acids. The lab has discovered a new pathway, the midnolin-proteasome pathway, that helps degrade key proteins involved in cancer, including several linked to blood cancers like multiple myeloma. The lab’s goal is to understand this pathway better and explore how it might be used to develop new treatments, especially for blood cancers, by targeting specific proteins that drive disease.

Cells must communicate with each other to maintain homeostasis and respond to external stimuli. This communication typically occurs through chemical signals or via direct physical contact. Dr. Fang plans to develop genomic tools to understand how different types of cells communicate with each other in the healthy brain and how communication goes awry in brain tumors. His goal is to determine whether and to what extent it is possible to manipulate specific genes or pathways underlying cell-cell communication to reverse disease progression in brain cancer patients.
 

Dr. Choi develops a technology called “Molecular recording”, which allows the recording of cellular events and their lineage information into each cell’s genome. These innovative tools are critical for understanding the development of individual cells, both in normal developmental processes and in diseases like cancer. Recently, Dr. Choi has successfully demonstrated this technology by engineering human cancer cells to record their lineage or signaling events in a culture dish (“in vitro”) using CRISPR-based genome editing methods. Moving forward, Dr. Choi plans to further develop these methods to study cancer development. The goal is to uncover how specific characteristics of cancer cells emerge, ultimately identifying new targets for treatment.
