在单细胞和多细胞生物体中,生物过程,特别是基因功能,自然地受到高时空分辨率的调节。基因、蛋白质和其他生物分子的活动在时间和位置上受到精确控制。在生物体发育过程中观察到的复杂生物过程中,这一点尤其明显。为了理解和研究这些过程及其在人类疾病中的错误调节,必须以自然界中发现的相同水平的时空分辨率来控制它们。在这里,光照射是一种独特的工具,因为它可以在时间、位置和幅度上轻松而精确地控制,从而使生物功能的精确激活和失活成为可能。本文不提供全面的文献综述,而是重点介绍用光控制生物(特别是细胞)功能的基本概念和要求。最近的例子被用来说明这些概念。感兴趣的读者可以在文献中找到关于生物活性分子的光化学调节的更多优秀和全面的评论。
Biological processes, particularly gene function, are naturally regulated with high spatiotemporal resolution in single cells and multicellular organisms. The activity of genes, proteins, and other biological molecules is precisely controlled in timing and location. This is especially evident during the complex biological processes observed in the development of an organism. In order to understand and to study these processes and their misregulation in human disease, it is imperative to control them with the same level of spatiotemporal resolution found in nature. Here, light irradiation represents a unique tool, because it can be easily and precisely controlled in timing, location, and amplitude; thus, light enables the precise activation and deactivation of biological function.Rather than providing a comprehensive literature review, this article focuses on the basic concepts and requirements of controlling biological (especially cellular) function with light. Recent examples are used to illustrate these concepts. The interested reader can find additional excellent and comprehensive reviews regarding the photochemical regulation of biologically active molecules in the literature.[1]
