Paul Macklin, PhD, a Professor of Intelligence Systems Engineering at Indiana University, spearheaded a groundbreaking approach to describing cell behavior using plain-language ‘hypothesis grammar.’ This innovative method allows researchers to construct mathematical models based on natural language statements, enabling the creation of digital representations of complex biological systems like cancer. By integrating biological knowledge and multiomics data, scientists can conduct virtual ‘thought experiments’ to enhance our comprehension of multicellular systems and develop new testable hypotheses. Unlike traditional methods that required custom code and technical expertise, this hypothesis grammar simplifies the encoding of intricate cellular behaviors and responses in a single line of human-readable text.
In a collaborative effort between Indiana University and the University of Maryland School of Medicine, researchers have developed a software tool that combines genomics technologies with computational modeling to forecast cell behavior variations over time. This approach mirrors the predictive capabilities of weather forecast models, offering insights into how cells interact within tissues and potentially influence diseases like cancer. The utilization of plain-language hypothesis grammar serves as a bridge between biological systems and computational models, facilitating the simulation of cellular actions within tissue environments.
One of the key highlights of this research is the ability to conduct virtual experiments exploring the behavior of cancer cells in response to their surroundings and the formation of neuronal layers in brain development. This multi-laboratory project emphasizes the importance of collaboration between software developers and clinical researchers, aiming to enhance our understanding of complex diseases such as cancer and neurodevelopmental disorders.
Through the integration of genomic data from real patient samples, the research team at the Institute for Genome Sciences (IGS) analyzed the behavior of breast and pancreatic cancer cells using spatial transcriptomics. By modeling scenarios where the immune system supports tumor growth rather than inhibiting it, the researchers shed light on the intricate dynamics of cancer progression. Additionally, the computational framework was adapted to simulate an immunotherapy clinical trial for pancreatic cancer, highlighting the individualized responses of virtual ‘patients’ to treatment.
The open-source nature of the newly developed grammar promotes accessibility and standardization within the scientific community, paving the way for widespread adoption of this innovative approach. By showcasing its applicability in diverse fields such as oncology and neuroscience, researchers are unlocking new possibilities in modeling cellular interactions and tissue ecosystems. This groundbreaking study not only advances our knowledge of complex diseases but also provides a framework for future research in precision medicine and systems biology.
