What is translation?
What is translation? Translation is a process that involves the synthesis of an amino acid chain from an mRNA blueprint. These polypeptide chains fold into functional proteins. Translation occurs outside the nucleus once nuclear [...]
How is transcription regulated in stem cells?
How is transcription regulated in stem cells? Pluripotent stem cells can potentially differentiate into any given cell type. They commonly exhibit mechanically softer nuclei [1], lack type-A lamins [2] and have a poorly defined [...]
How does chromatin remodeling impact gene transcription?
How does chromatin remodeling impact gene transcription? While chromosome territory dynamics is believed to regulate gene expression through the redistribution of genes and the subsequent co-localization of these genes with transcription machinery, changes are [...]
What are transcription factories?
What are transcription factories? The primary role of chromatin assembly is the compaction of an otherwise very long DNA molecule into discrete structures that fit into the nucleus. However, this compaction cannot be achieved [...]
How do chromosome territory dynamics affect gene redistribution?
How do chromosome territory dynamics affect gene redistribution? The spatial organization of chromatin within the 3-dimensional space of a chromosome territory enables the co-localization of co-transcribed genes and their transcriptional foci. Many gene positioning [...]

Research Interests
The morphology of cells, organs and whole organisms is determined by the generation of forces on the immediate environment, which is either extracellular matrix or adjacent cells. We are currently engaged in studies to understand the detailed molecular mechanisms involved in a variety of phenomena from cancer metastasis to brain function. Further, we are developing several new tools and protocols for measuring cell forces at the molecular level, which are revealing many new aspects of how cells can both generate and respond to external forces. We have an effort underway to define quantitatively the steps involved in cell adhesion to and spreading on a matrix-coated surface. Using a variety of cell lines that are missing proteins in various motility pathways, we are determining the quantitative changes in the spreading process. This will enable us to generate a detailed model of the process of spreading that will be a model for further studies of how cells differentiate, regenerate tissues or metastasize.
Biography
Hailing from Columbia University, Prof Michael Sheetz has more than 40 years’ experience in the biomedical field. Introduced to Singapore by Prof Hew Choy Leong of the National University of Singapore’s Department of Biological Sciences, Prof Sheetz was sought to lead an RCE project. This resulted in a two-year effort to organise and submit a proposal on Mechanobiology where Prof Sheetz set the theme and direction of the Mechanobiology Institute (MBI). As Founding Director of the MBI, he led the institute for 10 years and built it into a world-leading research centre in the field of mechanobiology.
