Understanding the molecular basis for mechanotransduction

In cells and tissues, the integration and propagation of mechanical signals is facilitated by the activity of molecular machines; small groups of proteins that detect and respond to mechanical stimuli by transferring physical forces to other cellular components, or facilitating their conversion to biochemical signals.

At MBI, we are exploring mechano-transduction though four major research programs: molecular, cellular, tissue, and through technological innovations.

The information obtained during this process, which is known as mechanosensing, helps in cellular decision making.This is particularly important during development, when stem cells are differentiating to become specific cell types, and during wound healing or tissue repair.

Cells can measure the stiffness of the surface on which they are growing and they can detect and respond to tension from neighboring cells within a tissue. Understanding how individual cells and proteins contribute to the mechanotransduction of physical force, is a major focus in the research conducted at the MBI. Dissecting the nanoscale architecture of various molecular machines involves the manipulation of specific cellular components, and at times, single proteins or specific protein domains. We can then monitor any subsequent effects.

Crucial to these efforts is the ability to control and modify the physical parameters of the cellular microenvironment. This means growing cells on substrates of a specific stiffness, pattern or shape. The effect of any molecular manipulation must then be monitored by quantifying the forces generated by cells or individual proteins, or visualizing the effects using super-resolution microscopy techniques.

Kenney’s laboratory is interested in signal transduction and the regulation of gene expression in prokaryotes. They are studying the two-component regulatory system EnvZ/OmpR that regulates the expression of outer membrane proteins as well as many other genes. Their present work focuses on how OmpR activates genes required for systemic infection in Salmonella enterica. Learn more.

Salmonella Lifestyle Choices

A bacterial molecular switch for infection or dormancy

Professor Linda Kenney describes a recent project from her lab on Salmonella pathogenesis. In this study, MBI Senior Research Fellow Dr Stuti Desai and colleagues discovered that the bacterial protein SsrB is the molecular switch for determining whether Salmonella infections become acute and virulent, or remain in a dormant carrier state.

Researchers from the Mechanobiology Institute (MBI), National University of Singapore have discovered that the bacterial protein SsrB is the molecular switch for determining whether Salmonella infections become acute and virulent, or remain in a dormant carrier state. This paper was published in eLife (Desai et al., The horizontally-acquired response regulator SsrB drives a Salmonella lifestyle switch by relieving biofilm silencing, February 2, 2016, eLife 2016; 5: e10747, doi: 10.7554/eLife.10747).
