These findings suggest the potential for photophysical and photochemical control of MT dynamics, which have been correlated with the regulation and partitioning of reactive oxygen species (ROS) in living cells. Endogenous, optical ultraweak photon emissions (UPEs) from living organisms are well-documented in the context of ROS-mediated oxidative stress. Stress-induced ultraviolet UPEs are more prominent during the exponential growth phase of the cellular cycle, implicating them in potential biophotonic signaling along aromatic networks during oxidative metabolism.
