Exploring Cellular Stability and Adaptation
Understanding how cells maintain stability while adapting to environmental stress is critical to the research conducted by UC Riverside synthetic biologist Sonali Chaturvedi. Awarded a $2.1 million grant from the National Institutes of Health (NIH), Chaturvedi’s five-year project will delve into the molecular control systems and transcriptional feedback circuits that dictate gene expression and cellular responses.
Trillions of cells in the body constantly receive environmental signals. Despite the potential for dangerous gene activation that could lead to diseases such as cancer and diabetes, these occurrences remain rare due to the extraordinary reliability of cellular functions. Chaturvedi aims to uncover the fundamental rules that allow cells to remain stable while still adapting to various stresses, which is essential for most biological processes.
Chaturvedi’s research will focus on whether cells pass on more than just DNA to their progeny. The team will examine the concept of “molecular memories,” exploring how patterns of gene regulation inherited from parent cells might influence the responses of daughter and granddaughter cells to stressors. By simplifying complex transcriptional feedback circuits and testing them under various conditions, researchers hope to identify generalized principles that apply across different cell types.
The project shifts from Chaturvedi’s previous focus on genetic information transfer to a foundational investigation of how cells consistently make the correct decisions under stress. Cells are subject to numerous stress factors including infections, temperature fluctuations, nutrient shortages, DNA damage, and exposure to toxins. Insights gained from this research could lead to improved understanding of diseases caused by faulty gene regulation, especially those triggered by stress, and could inform the development of engineered cells with applications in cancer treatment and regenerative medicine.
The R35 award from the NIH is specifically designed to encourage innovative and curiosity-driven research rather than confining investigators to narrowly defined projects. This flexibility allows scientists to pursue unexpected findings as they arise, making it an ideal approach for uncovering the fundamental rules governing cell behavior.
“This grant gives us the freedom to ask big questions,” Chaturvedi remarked. By grasping how cells sustain both stability and flexibility, the research team anticipates a deeper understanding of life’s fundamental mechanisms and greater insights into cellular decision-making processes.
