A Predictive Model for Selective Targeting of the Warburg Effect through GAPDH Inhibition with a Natural Product.

Cell metabolism | Oct 3, 2017

Targeted cancer therapies that use genetics are successful, but principles for selectively targeting tumor metabolism that is also dependent on the environment remain unknown. We now show that differences in rate-controlling enzymes during the Warburg effect (WE), the most prominent hallmark of cancer cell metabolism, can be used to predict a response to targeting glucose metabolism. We establish a natural product, koningic acid (KA), to be a selective inhibitor of GAPDH, an enzyme we characterize to have differential control properties over metabolism during the WE. With machine learning and integrated pharmacogenomics and metabolomics, we demonstrate that KA efficacy is not determined by the status of individual genes, but by the quantitative extent of the WE, leading to a therapeutic window in vivo. Thus, the basis of targeting the WE can be encoded by molecular principles that extend beyond the status of individual genes.

MATLAB

A multi-paradigm numerical computing environment and fourth-generation programming language. It allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, Java, Fortran and Python. (Adapted from Wikipedia) The high-level language and interactive environment lets you explore and visualize ideas and collaborate across disciplines including signal and image processing, communications, control systems, and computational finance.

R Project for Statistical Computing

Software environment and programming language for statistical computing and graphics that provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, etc) and graphical techniques. R is an integrated suite of software facilities for data manipulation, calculation and graphical display.

Clustal Omega

Multiple sequence alignment tool for proteins that uses seeded guide trees and HMM profile-profile techniques to produce biologically meaningful multiple sequence alignments of divergent sequences. Evolutionary relationships can be seen via viewing Cladograms or Phylograms. SOAP Web services and source code are also available. Aligning multiple sequences highlights areas of similarity which may be associated with specific features that have been more highly conserved than other regions. These regions in turn can help classify sequences or to inform experiment design. Multiple sequence alignment is also an important step for phylogenetic analysis, which aims to model the substitutions that have occurred over evolution and derive the evolutionary relationships between sequences. There are two ways to use this service at the EBI. The first is interactively (default) and the second is by email. Using it interactively, the user must wait for the results to be displayed in the browser window. The email option means that the results will not be displayed in the browser window but instead a link to the results will be sent by email. The email option is the better one to take when submitting large amounts of data or a job that might take a long time to run. The program accepts nucleic acid or protein sequences, in the following multiple sequence formats: NBRF/PIR, EMBL/UniProt, Pearson (FASTA), GDE, ALN/Clustal, GCG/MSF, RSF.

ImageJ

A Java image processing program which can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and raw. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.4 or later virtual machine. Downloadable distributions are available for Windows, Mac OS, Mac OS X and Linux. It supports stacks, a series of images that share a single window. It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations. It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering. It does geometric transformations such as scaling, rotation and flips. Image can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. The program supports any number of windows (images) simultaneously, limited only by available memory. Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. Density or gray scale calibration is also available. ImageJ was designed with an open architecture that provides extensibility via Java plugins. Custom acquisition, analysis and processing plugins can be developed using ImageJ built in editor and Java compiler. User-written plugins make it possible to solve almost any image processing or analysis problem.

Gene Set Enrichment Analysis

A computational software that determines whether an a priori defined set of genes shows statistically significant, concordant differences between two biological states (e.g. phenotypes). Additional resources to analyze, annotate and interpret enrichment results are also available including the Molecular Signatures Database (MSigDB), a collection of annotated gene sets for use with GSEA software.

BioModels Database

Repository of peer-reviewed, published, computational models that allows biologists to store, search and retrieve published mathematical models from the field of systems biology, but also more generally those of biological interest. Models in the database can be used to generate sub-models, can be simulated online, and can be converted between different representational formats. This resource also features programmatic access via Web Services. Each model is curated to verify that it corresponds to the reference publication and gives the proper numerical results. Curators also annotate the components of the models with terms from controlled vocabularies and links to other relevant data resources allowing users to search accurately for the models they need. The models can be retrieved in the SBML format and import/export facilities are being developed to extend the spectrum of formats supported by the resource.
