An increasing set of optogenetic tools enables tightly controlled regulation of ion flux across biological membranes, gene expression, gene editing, and protein–protein interactions and is being used to interrogate hallmark traits of cancer at the cellular, subcellular, and organismic level. This enables, on the one hand, the identification of critical signaling circuits required for cancer development and progression in vitro and in animal models and can flag potential intervention points for pharmacologic interference. On the other hand, optogenetics can improve the level of control in cell-based therapeutics. The current article provides areview of optogenetic tools and approaches used in the cancer research field and their multiple applications for improving our understanding of signal transduction pathways, modulating immune functions in the tumor microenvironment, facilitating drug screening, or directly attacking cancer cells. Key advantages and achievements of optogenetics in the cancer research field and remaining barriers for clinical applications are discussed.  \nKeywords: optogenetics; cancer research; signal transduction; immune cell modulation; cancer therapy  \n1. Introduction and a Glimpse of History  \nOptogenetics is a biological approach that combines optical and genetic methods to control cell functions. The technology typically involves artificially incorporating DNA sequences that encode light-sensitive proteins or protein domains, which are often derived from plants or microorganisms, into selected cells or organisms [1,2] . Once the encoded proteins are expressed in the receiving cells, their activity can be controlled with light, which in turn enables a light-mediated control of a wide spectrum of specific cell functions depending on the engineered proteins. DNA constructs are delivered using established transfection techniques including plasmids, viral vectors, or bacterial carriers [3] . Optogenetic proteins can, for instance, function as ion channels, cell surface receptors, or various components of cell signaling cascades [4] .  \nOptogenetics originated in the field of neuroscience in response to a critical need for selective control of individual neurons while leaving surrounding neurons unaltered. Previously thought tobe unattainable, a 2005 article demonstrated that neurons could be engineered to respond to light upon the integration of microbial opsin genes without the need  \nfor additional components [1,5] . In subsequent years, optogenetics has become a powerful tool to dissect physiological and pathophysiological neuronal circuits and processes [1,6] . Specifically, the modulation of neuronal behavior is achieved by altering membrane potential using photoreceptive proteins including bacteriorhodopsin (BR), halorhodopsin (NpHR), and channelrhodopsin-2 (ChR","cbCaiaAdqXW0JanM","https://ap.wps.com/l/cbCaiaAdqXW0JanM","pdf",4944226,26,"English","# Introduction and a Glimpse of History\n# Key Features and Advantages of Optogenetics","[{\"question\":\"How does optogenetics enable precise control of cell functions relevant to cancer?\",\"answer\":\"Optogenetics combines engineered light-sensitive proteins with light exposure, allowing light-mediated regulation of ion flux, gene expression, and signaling components in selected cells.
