How the Timing of Biological Processes Is Controlled and Modified at the Molecular and Cellular Level? 2.0.

This document discusses the importance of timing in biological processes and the challenges in understanding how cells and organisms measure and regulate time. It introduces a special issue that includes articles on various aspects of temporal regulation in cells, tissues, and organisms. The articles cover topics such as the regulation of the cell cycle, the timing of mitotic divisions, the duration of the S phase of the cell cycle, the interaction between circadian clocks and other factors, and the role of microRNAs in human endometrium development. The document emphasizes the relevance of studying time-related processes in the context of an aging population and the potential for future clinical therapies. [Extracted from the article]
