With the recent revolution in Molecular Biology and the deciphering of the Human Genome, understanding of the building blocks that comprise living systems has advanced rapidly. We have yet to understand, however, how the physical forces that animate life affect the synthesis, folding, assembly, and function of these molecular building blocks. We are equally uncertain as to how these building blocks interact dynamically to create coupled regulatory networks from which integrative biological behaviors emerge. Here we review recent advances in the field of biomechanics at the cellular and molecular levels, and set forth challenges confronting the field. Living systems work and move as multi-molecular collectives, and in order to understand key aspects of health and disease we must first be able to explain how physical forces and mechanical structures contribute to the active material properties of living cells and tissues, as well as how these forces impact information processing and cellular decision making. Such insights will no doubt inform basic biology and rational engineering of effective new approaches to clinical therapy.
随着分子生物学领域最近的革命以及人类基因组的破译,对构成生命系统的基本组成部分的理解有了迅速进展。然而,我们尚未理解赋予生命活力的物理力如何影响这些分子基本组成部分的合成、折叠、组装和功能。我们同样不确定这些基本组成部分如何动态相互作用以创建耦合调节网络,从而产生综合生物行为。在此,我们回顾细胞和分子水平生物力学领域的最新进展,并阐述该领域面临的挑战。生命系统作为多分子集合体进行运作和移动,为了理解健康和疾病的关键方面,我们首先必须能够解释物理力和机械结构如何有助于活细胞和组织的活性物质特性,以及这些力如何影响信息处理和细胞决策。这些见解无疑将为基础生物学和有效临床治疗新方法的合理工程设计提供依据。
