Regulatory networks refer to the complex systems of genes and proteins that work together to control gene expression and cellular processes in living organisms. These networks play a key role in determining how genes are turned on and off, and how cells respond to different stimuli and signals. Research in this area aims to understand the structure and function of regulatory networks, as well as how they are disrupted in disease states. This often involves the use of computational models, high-throughput sequencing techniques, and experimental approaches to map out the interactions between different components of the network and identify key regulatory nodes. By studying regulatory networks, researchers can gain insights into the underlying mechanisms of cellular function and dysfunction, and develop new therapeutic strategies for treating a variety of diseases.
