Five breakthrough technologies to accelerate drug discovery and development
Facilitating anti-cancer drug discovery with selective inhibitors of ubiquitin
El Bachir Affar (Research Centre of the Hôpital Maisonneuve-Rosemont, Université de Montréal) and Sachdev Sidhu (University of Toronto), $300,000/2 years
Human cells dispose of damaged or non-functional proteins using a highly sophisticated protein degradation system. However, abnormalities in protein degradation are frequently observed in many diseases, including several types of cancer. In most cases, this can be attributed to the misbehaviour of a cellular machinery employing a small protein called ubiquitin, which attaches to target proteins and acts as a signal for their destruction. Ubiquitin attachment or removal, ensured by distinct and critical sets of enzymes, is highly coordinated. These enzymes, that have attracted increasing attention as novel targets for drug development, are crucial mediators of key intracellular processes and their manipulation has a profound impact on protein activity, localization, and life span and therefore on human physiopathology. Unfortunately, the paucity of selective molecules that modulate the function of these enzymes has severely hampered attempts to manipulate them for therapeutic benefits. This project will use protein engineering technology to enable the discovery and development of highly specific and potent ubiquitin-like molecules that associate tightly with these enzymes in a manner that will block their catalytic function (inhibitors) or alternatively enhance their function (activators). The inhibitory or activating function of these molecules will then be validated preclinically using established biological assays. This could lead to the discovery and validation of novel therapeutic targets, further translate fundamental findings into pharmaceutical research, and guide the development of therapeutic molecules for diseases where these processes are deregulated.
Genetic interactions studies to better establish efficacious drug targets
Tomas Babak and Xiaolong Yang (Queen's University), $300,000/2 years
A major challenge for pharmaceutical companies is identifying efficacious drug targets. Genetic interactions, where the effects of disrupting multiple genes at once are measured, enable unbiased interrogation of functional relationships between any genes of interest. When applied to many genes systematically, an interaction network emerges, and this has proven to be profoundly informative for globally mapping pathways and understanding how a cell operates. Tomas Babak's team approach aims at discovering efficacious drug targets and biomarkers by comprehensively mapping interactions between established disease pathways and all known genes. Given the practical merits, the approach will also enable custom screens to identify effects specific to genetic background in diverse environments such as in systems that model disease progression or in patient-specific cells. This project will be developing a technology for generating interaction networks that will work in human cells, will be sufficiently high-throughput to enable genome-wide interaction screens, simultaneously detect effects of single, pairwise, and triple gene knockouts, exceed the cost and technical limitations encountered of to now and have an overall impact at all stages of drug development.
Drug delivery: silencing RNAs using exosomes
Derrick Gibbings (University of Ottawa), $300,000/2 years
Early research has shown that a new type of molecule called silencing RNAs could be readily designed to silence or inhibit virtually any gene in a very specific and powerful manner. This in turns eliminates the expression of the protein encoded by this gene. Because most diseases could benefit from shutting-down the action of a specific protein, it is suggested that silencing RNAs could be used to treat virtually any diseases. Unfortunately, a roadblock has prevented use of silencing RNAs to treat most diseases: the ability to deliver these drugs into the tissues and organs where they are needed. The body makes its own equivalent of silencing RNAs, and uses tiny vesicles called exosomes to transport these between cells. The project aims to utilize these natural vesicles to deliver therapeutic silencing RNAs. Derrick Gibbings will test his novel technology for packaging silencing RNAs into exosomes and test where silencing RNAs delivered by exosomes are active in the body. With this knowledge he can begin to use exosomes to deliver silencing RNAs and treat diseases associated with this tissue. In the long-term he will modify exosomes to target other tissues and enable treatment of further diseases. This would enable the treatment of many previously untreatable diseases with silencing RNAs.
3D liver tissue models to screen the effects of drugs
Craig Simmons, Michael Sefton, Denis Grant and M. Dean Chamberlain (University of Toronto), $300,000/2 years
Poor efficacy and unpredictable toxic effects are leading causes for removal of a drug from the market. Many drugs act unpredictably in patients because the preclinical studies performed poorly mimic humans. In particular, the liver requires special attention as it responsible for metabolizing drugs. Thus improved liver models could identify and eliminate toxic and ineffective drugs earlier in the drug discovery process. To meet this need, Craig Simmons' team has developed three-dimensional liver microtissues that demonstrate improved functionality over standard liver models. The team proposes to incorporate these microtissues in a microfluidic platform that they have created to model arrays of tissues that contain blood vessels, like the liver. This new and improved liver model will be unique in its compatibility with standard laboratory equipment and the pharmaceutical industry R&D processes, ensuring ease of implementation with minimal time and effort. They will optimize the new liver model to achieve functionality more similar to native human liver tissue than is possible with conventional models. They will then validate the system by screening a panel of compounds to detect adverse metabolic and toxic effects that are overlooked by conventional drug screening methods. At project completion, they will deliver a new best-in-class model of human liver that is expected to decrease the time and cost associated with drug development by identifying ineffective and toxic drugs much earlier in the drug development process than is possible with current methods.
Mammalian Membrane Two Hybrid (MaMTH), an innovative technology for drug discovery
Igor Stagljar (University of Toronto), $300,000/2 years
Igor Stagljar and his team have worked over the last 12 years to understand how interactions among a special class of proteins, called membrane proteins, produce either healthy or diseased cells. These proteins, which make up approximately one-third of all proteins in a cell, are responsible for a variety of processes, making them attractive therapeutic targets for many diseases such as hypertension, diabetes, neurological disorders and various types of cancer. However, membrane proteins have been extremely difficult to study in the past because of their biochemical complexity. The research team has recently developed a novel translational research tool called MaMTH that allows researchers to study the interactions of any membrane protein of interest as well as understand how such protein interactions respond to various therapeutic compounds in the context of any human cell. The purpose of this research project is to modify MaMTH into a powerful new drug discovery assay that can be used for the unbiased discovery of small molecules that can disrupt protein interactions of any membrane protein of therapeutic interest.
