April 24, 2024 Cells may possess hidden communication system

Cells constantly navigate a dynamic environment, facing ever-changing conditions and challenges. But how do cells swiftly adapt to these environmental fluctuations? A new Moffitt Cancer Center study, published in iScience, is answering that question by challenging our understanding of how cells function. A team of researchers suggests that cells possess a previously unknown information processing system that allows them to make rapid decisions independent of their genes.

For decades, scientists have viewed DNA as the sole source of cellular information. This DNA blueprint instructs cells on how to build proteins and carry out essential functions. However, new research at Moffitt led by Dipesh Niraula, Ph.D., and Robert Gatenby, M.D., discovered a nongenomic information system that operates alongside DNA, enabling cells to gather information from the environment and respond quickly to changes. The study focused on the role of ion gradients across the cell membrane. These gradients, maintained by specialized pumps, require large energy expenditure to generate varying transmembrane electrical potentials. The researchers proposed that the gradients represent an enormous reservoir of information that allows cells to monitor their environment continuously. When information is received at some point on the cell membrane, it interacts with specialized gates in ion-specific channels, which then open, allowing those ions to flow along the pre-existing gradients to form a communication channel. The ion fluxes trigger a cascade of events adjacent to the membrane, allowing the cell to analyze and rapidly respond to the information. When the ion fluxes are large or prolonged, they can cause self-assembly of the microtubules and microfilaments for the cytoskeleton. Typically, the cytoskeleton network provides mechanical support for the cell and is responsible for cell shape and movement. However, the Moffitt researchers noted that proteins from the cytoskeleton are also excellent ion conductors. This allows the cytoskeleton to act as a highly dynamic intracellular wiring network to transmit ion-based information from the membrane to the intracellular organelles, including mitochondria, endoplasmic reticulum and the nucleus. The researchers suggested that this system, which allows for rapid and local responses to specific signals, can also generate coordinated regional or global responses to larger environmental changes. "Our research reveals the capability of cells to harness transmembrane ion gradients as a means of communication, allowing them to sense and respond to changes in their surroundings rapidly," said Niraula, an applied research scientist in the Department of Machine Learning. "This intricate network enables cells to make swift and informed decisions, critical for their survival and function." The researchers believe that this nongenomic information system is critical for forming and maintaining normal multicellular tissue and suggests the well described ion fluxes in neurons represent a specialized example of this broad information network. Disruption of these dynamics may also be a critical component of cancer development. They demonstrated their model was consistent with multiple experimental observations and highlighted several testable predictions arising from their model, hopefully paving the way for future experiments to validate their theory and shed light on the intricacies of cellular decision-making. "This study challenges the implicit assumption in biology that the genome is the sole source of information, and that the nucleus acts as a kind of central processor. We present an entirely new network of information that allows rapid adaptation and sophisticated communication necessary for cell survival and probably deeply involved in the intercellular signaling that permits functioning multicellular organisms," said Gatenby, co-director of the Center of Excellence for Evolutionary Therapy at Moffitt. This work was supported by the National Institutes of Health (R01-CA233487).

Commentary: The proposed nongenomic information processing system in cells challenges the notion that such coordinated systems could have emerged through a stepwise evolutionary process. This system relies on the simultaneous implementation of both the "hardware" and "software" components, making it improbable to have arisen gradually. The "hardware" aspect of this system involves the specialized structures and components necessary for its functioning. These include the ion channels, pumps, and gradients across the cell membrane, as well as the cytoskeleton network that acts as a dynamic intracellular wiring system.  Moreover, the "software" aspect, which refers to the mechanisms and processes that govern the system's operation, is equally complex. This includes the ability of the cell to sense environmental changes, interpret the information carried by ion fluxes, and coordinate a rapid and appropriate response through the self-assembly of the cytoskeleton and the transmission of signals to various organelles. The development of such sophisticated information processing and decision-making capabilities, which are essential for the system's functionality, is extremely unlikely to have occurred through random, undirected processes. The system exhibits characteristics of irreducible complexity, where the removal or absence of any of its components would render the entire system non-functional.  The existence of such  an interdependent system, with both hardware and software components working in tandem, suggests the involvement of an intelligent designer who purposefully created and integrated these elements to achieve the desired functionality.
