  • Towards Complete Descriptions of the Free-Energy Landscapes of Proteins by Michele Vendruscolo and Christopher M
    FirstCite® Phil. Trans. R. Soc. A (2005) e-publishing doi:10.1098/rsta.2004.1501 Towards complete descriptions of the free-energy landscapes of proteins By Michele Vendruscolo and Christopher M. Dobson Department of Chemistry, University of Cambridge, Lensfield Road, Cambridge CB2 1EW, UK ([email protected]) In recent years increasingly detailed information about the structures and dynamics of protein molecules has been obtained by innovative applications of experimental techniques, in particular nuclear magnetic resonance spectroscopy and protein engi- neering, and theoretical methods, notably molecular dynamics simulations. In this article we discuss how such approaches can be combined by incorporating a wide range of different types of experimental data as restraints in computer simulations to provide unprecedented detail about the ensembles of structures that describe pro- teins in a wide variety of states from the native structure to highly unfolded species. Knowledge of these ensembles is beginning to enable the complete free-energy land- scapes of individual proteins to be defined at atomic resolution. This strategy has provided new insights into the mechanism by which proteins are able to fold into their native states, or by which they fail to do so and give rise to harmful aggregates that are associated with a wide range of debilitating human diseases. Keywords: protein folding; energy landscape; protein misfolding; protein aggregation; amyloid diseases; computer simulations 1. Introduction Characterizing the nature of partially folded states of proteins is crucial for under- standing the determinants of many aspects of their behaviour, including the stability of the native state, the kinetics of folding and the mechanisms of misfolding (Ven- druscolo et al.

Though the elements regulating cellular states have been identified, the underlying dynamic mechanisms and the significance of such cellular heterogeneity remain elusive. Results: We present a gene regulatory network model to investigate the bimodal Nanog distribution in stem cells. Our model reveals a novel role of dynamic conversion between the cellular states of high and low Nanog levels. Model simulations demonstrate that the low-Nanog state benefits cell differentiation through serving as an intermediate state to reduce the barrier of transition. Interestingly, the existence of low-Nanog state dynamically slows down the reprogramming process, and additional Nanog activation is found to be essential to quickly attaining the fully reprogrammed cell state.

  • Protein Solubility and Protein Homeostasis: a Generic View of Protein Misfolding Disorders
    Downloaded from http://cshperspectives.cshlp.org/ on September 30, 2021 - Published by Cold Spring Harbor Laboratory Press Protein Solubility and Protein Homeostasis: A Generic View of Protein Misfolding Disorders Michele Vendruscolo, Tuomas P.J. Knowles, and Christopher M. Dobson Department of Chemistry, University of Cambridge, Cambridge CB2 1EW, United Kingdom Correspondence: [email protected] According to the “generic view” of protein aggregation, the ability to self-assemble into stable and highly organized structures such as amyloid fibrils is not an unusual feature exhibited by a small group of peptides and proteins with special sequence or structural properties, but rather a property shared by most proteins. At the same time, through a wide variety of techniques, many of which were originally devised for applications in other disciplines, it has also been established that the maintenance of proteins in a soluble state is a fundamental aspect of protein homeostasis. Taken together, these advances offer a unified framework for understanding the molecular basis of protein aggregation and for the rational development of therapeutic strategies based on the biological and chemical regulation of protein solubility. irtually every complex biochemical process structures that results from protein folding, and Vtaking place in living cells depends on the which serve to bring key functional groups into ability of the molecules involved to self- close proximity, has enabled living systems to assemble into functional structures (Dobson develop an astonishing diversity and selectivity 2003; Robinson et al. 2007; Russel et al. 2009), in their underlying chemical processes by using and a sophisticated quality control system is a common set of just 20 basic molecular com- responsible for regulating the reactions leading ponents, the amino acids (Dobson 2003).

Commun., 2015, 51, 14425 and protein aggregates Maya A. Wright, Francesco A. Aprile, Paolo Arosio, Michele Vendruscolo, Christopher M. Dobson and Tuomas P. J. Knowles* Molecular chaperones are key components of the arsenal of cellular defence mechanisms active against protein aggregation. In addition to their established role in assisting protein folding, increasing evidence indicates that molecular chaperones are able to protect against a range of potentially damaging aspects of protein behaviour, including misfolding and aggregation events that can result in the generation of aberrant protein assemblies whose formation is implicated in the onset and progression of neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases. The interactions between molecular chaperones and different amyloidogenic protein species are difficult to study owing to the inherent heterogeneity of the aggregation process as well as the dynamic nature of molecular chaperones under physiological conditions.

  • The University of Chicago-Educated Chinese Phds of 1915-1960
    The Untold Stories: The University of Chicago-educated Chinese PhDs of 1915-1960 Frederic Xiong* ------------------------------------------------------------------------------------------------------------------------------ Abstract In modern Chinese history, there have been three major waves of Chinese students going to study in the United States. The second wave began in the late 19th century and continued up to 1960. Through political turmoil, two Sino-Japanese Wars, the Chinese Civil War, the regime-change in 1911, the Communists’ victory in 1949, and Korean War, 2,455 Chinese students earned Doctorates of Philosophy (PhD) degrees from 116 American colleges and universities. The University of Chicago (UChicago), a prestigious research university, educated 142 of those students, the fourth highest number among universities in the U.S. This paper presents the first comprehensive list of Chinese scholars awarded PhDs at UChicago from 1915 to 1960, as well as descriptions of their achievements and what they did after graduation. It also explores the lives of Chinese PhDs who chose to stay in the U.S., as well as those who returned to China after the Communists came to power. Those who stayed in the U.S. later helped China when it reopened its borders to outside of the world. Those who returned to China suffered greatly during the political upheavals—especially the Cultural Revolution, in which at least a dozen lost their lives. PART I Chinese Students Studying in the U.S. In modern Chinese history, there have been three major waves of Chinese students going to study in the U.S. The first wave can be traced back to 1847 when Yung Wing (容闳, 1828-1912) became the first Chinese student to study in the U.S.
