Compact Course: "Virtual Screening of Drug Discovery"

Prof. Markus Lill, Purdue University
26-29th June 2017

Virtual screening has become an essential element of the drug discovery process. Virtual screening is used to search a large library of small molecules for binding to a target protein and select a small subset of compounds for subsequent experimental validation and optimization. In this block course we will discuss the methodological basis and practical applications of structure-based and ligand-based virtual screening methods such as docking, shape-based, pharmacophore and fingerprint concepts.

The course alternates lectures and practical sections in the computer lab.

Talk: "Modelling glioma growth with fully anisotropic diffusion"

Prof. Thomas Hillen, University of Alberta
6th June 2017

The human brain has a complex geometric structure consisting of white and gray matter, blood vessels, ventricles, skull etc. It forms a highly anisotropic medium. Glioma in the brain are known to invade along white matter tracks and along other brain structures. Using diffusion tensor imaging (DTI) it is now possible to obtain directional information of the brain geometry. In my talk I will show how this DTI information can be used to parametrize a fully anisotropic diffusion equation for glioma spread. We validate the model on clinical data of glioma patients and discuss the future use in treatment design. (joint work with A. Swan, K.J. Painter, C. Surulescu, C. Engwer, M. Knappitsch, A. Murtha).

Talk: "Analytical approximations for spatial stochastic gene expression in single cells and tissues"

Dr. Ramon Grima, Edinburgh University
8th March 2017

Gene expression occurs in an environment in which both stochastic and diffusive effects are significant. Spatial stochastic simulations are computationally expensive compared to their deterministic counterparts and hence little is currently known of the significance of intrinsic noise in a spatial setting. I will show how starting from the reaction-diffusion master equation (RDME) describing stochastic reaction-diffusion processes, we can derive closed-form expressions for the approximate steady-state mean concentrations which are explicit functions of the dimensionality of space, rate constants and diffusion coefficients. These are generally different from those given by the deterministic theory of reaction-diffusion processes, thus highlighting the importance of intrinsic noise. Our theory is confirmed by comparison with stochastic simulations, using the RDME and Brownian dynamics, of two models of stochastic and spatial gene expression in single cells and tissues. Lastly, time permitting, I will discuss how one can extend these results to stochastic spatial simulations of intracellular processes which take into account macromolecular crowding, namely the volume exclusion due to the finite size of molecules.
